For both users' and\nauthors' sake, the GPL requires that modified versions be marked as\nchanged, so that their problems will not be attributed erroneously to\nauthors of previous versions.\n\n  Some devices are designed to deny users access to install or run\nmodified versions of the software inside them, although the manufacturer\ncan do so.  This is fundamentally incompatible with the aim of\nprotecting users' freedom to change the software.  The systematic\npattern of such abuse occurs in the area of products for individuals to\nuse, which is precisely where it is most unacceptable.  Therefore, we\nhave designed this version of the GPL to prohibit the practice for those\nproducts.  If such problems arise substantially in other domains, we\nstand ready to extend this provision to those domains in future versions\nof the GPL, as needed to protect the freedom of users.\n\n  Finally, every program is threatened constantly by software patents.\nStates should not allow patents to restrict development and use of\nsoftware on general-purpose computers, but in those that do, we wish to\navoid the special danger that patents applied to a free program could\nmake it effectively proprietary.  To prevent this, the GPL assures that\npatents cannot be used to render the program non-free.\n\n  The precise terms and conditions for copying, distribution and\nmodification follow.\n\n                       TERMS AND CONDITIONS\n\n  0. Definitions.\n\n  \"This License\" refers to version 3 of the GNU General Public License.\n\n  \"Copyright\" also means copyright-like laws that apply to other kinds of\nworks, such as semiconductor masks.\n\n  \"The Program\" refers to any copyrightable work licensed under this\nLicense.  Each licensee is addressed as \"you\".  \"Licensees\" and\n\"recipients\" may be individuals or organizations.\n\n  To \"modify\" a work means to copy from or adapt all or part of the work\nin a fashion requiring copyright permission, other than the making of an\nexact copy.  The resulting work is called a \"modified version\" of the\nearlier work or a work \"based on\" the earlier work.\n\n  A \"covered work\" means either the unmodified Program or a work based\non the Program.\n\n  To \"propagate\" a work means to do anything with it that, without\npermission, would make you directly or secondarily liable for\ninfringement under applicable copyright law, except executing it on a\ncomputer or modifying a private copy.  Propagation includes copying,\ndistribution (with or without modification), making available to the\npublic, and in some countries other activities as well.\n\n  To \"convey\" a work means any kind of propagation that enables other\nparties to make or receive copies.  Mere interaction with a user through\na computer network, with no transfer of a copy, is not conveying.\n\n  An interactive user interface displays \"Appropriate Legal Notices\"\nto the extent that it includes a convenient and prominently visible\nfeature that (1) displays an appropriate copyright notice, and (2)\ntells the user that there is no warranty for the work (except to the\nextent that warranties are provided), that licensees may convey the\nwork under this License, and how to view a copy of this License.  If\nthe interface presents a list of user commands or options, such as a\nmenu, a prominent item in the list meets this criterion.\n\n  1. Source Code.\n\n  The \"source code\" for a work means the preferred form of the work\nfor making modifications to it.  \"Object code\" means any non-source\nform of a work.\n\n  A \"Standard Interface\" means an interface that either is an official\nstandard defined by a recognized standards body, or, in the case of\ninterfaces specified for a particular programming language, one that\nis widely used among developers working in that language.\n\n  The \"System Libraries\" of an executable work include anything, other\nthan the work as a whole, that (a) is included in the normal form of\npackaging a Major Component, but which is not part of that Major\nComponent, and (b) serves only to enable use of the work with that\nMajor Component, or to implement a Standard Interface for which an\nimplementation is available to the public in source code form.  A\n\"Major Component\", in this context, means a major essential component\n(kernel, window system, and so on) of the specific operating system\n(if any) on which the executable work runs, or a compiler used to\nproduce the work, or an object code interpreter used to run it.\n\n  The \"Corresponding Source\" for a work in object code form means all\nthe source code needed to generate, install, and (for an executable\nwork) run the object code and to modify the work, including scripts to\ncontrol those activities.  However, it does not include the work's\nSystem Libraries, or general-purpose tools or generally available free\nprograms which are used unmodified in performing those activities but\nwhich are not part of the work.  For example, Corresponding Source\nincludes interface definition files associated with source files for\nthe work, and the source code for shared libraries and dynamically\nlinked subprograms that the work is specifically designed to require,\nsuch as by intimate data communication or control flow between those\nsubprograms and other parts of the work.\n\n  The Corresponding Source need not include anything that users\ncan regenerate automatically from other parts of the Corresponding\nSource.\n\n  The Corresponding Source for a work in source code form is that\nsame work.\n\n  2. Basic Permissions.\n\n  All rights granted under this License are granted for the term of\ncopyright on the Program, and are irrevocable provided the stated\nconditions are met.  This License explicitly affirms your unlimited\npermission to run the unmodified Program.  The output from running a\ncovered work is covered by this License only if the output, given its\ncontent, constitutes a covered work.  This License acknowledges your\nrights of fair use or other equivalent, as provided by copyright law.\n\n  You may make, run and propagate covered works that you do not\nconvey, without conditions so long as your license otherwise remains\nin force.  You may convey covered works to others for the sole purpose\nof having them make modifications exclusively for you, or provide you\nwith facilities for running those works, provided that you comply with\nthe terms of this License in conveying all material for which you do\nnot control copyright.  Those thus making or running the covered works\nfor you must do so exclusively on your behalf, under your direction\nand control, on terms that prohibit them from making any copies of\nyour copyrighted material outside their relationship with you.\n\n  Conveying under any other circumstances is permitted solely under\nthe conditions stated below.  Sublicensing is not allowed; section 10\nmakes it unnecessary.\n\n  3. Protecting Users' Legal Rights From Anti-Circumvention Law.\n\n  No covered work shall be deemed part of an effective technological\nmeasure under any applicable law fulfilling obligations under article\n11 of the WIPO copyright treaty adopted on 20 December 1996, or\nsimilar laws prohibiting or restricting circumvention of such\nmeasures.\n\n  When you convey a covered work, you waive any legal power to forbid\ncircumvention of technological measures to the extent such circumvention\nis effected by exercising rights under this License with respect to\nthe covered work, and you disclaim any intention to limit operation or\nmodification of the work as a means of enforcing, against the work's\nusers, your or third parties' legal rights to forbid circumvention of\ntechnological measures.\n\n  4. Conveying Verbatim Copies.\n\n  You may convey verbatim copies of the Program's source code as you\nreceive it, in any medium, provided that you conspicuously and\nappropriately publish on each copy an appropriate copyright notice;\nkeep intact all notices stating that this License and any\nnon-permissive terms added in accord with section 7 apply to the code;\nkeep intact all notices of the absence of any warranty; and give all\nrecipients a copy of this License along with the Program.\n\n  You may charge any price or no price for each copy that you convey,\nand you may offer support or warranty protection for a fee.\n\n  5. Conveying Modified Source Versions.\n\n  You may convey a work based on the Program, or the modifications to\nproduce it from the Program, in the form of source code under the\nterms of section 4, provided that you also meet all of these conditions:\n\n    a) The work must carry prominent notices stating that you modified\n    it, and giving a relevant date.\n\n    b) The work must carry prominent notices stating that it is\n    released under this License and any conditions added under section\n    7.  This requirement modifies the requirement in section 4 to\n    \"keep intact all notices\".\n\n    c) You must license the entire work, as a whole, under this\n    License to anyone who comes into possession of a copy.  This\n    License will therefore apply, along with any applicable section 7\n    additional terms, to the whole of the work, and all its parts,\n    regardless of how they are packaged.  This License gives no\n    permission to license the work in any other way, but it does not\n    invalidate such permission if you have separately received it.\n\n    d) If the work has interactive user interfaces, each must display\n    Appropriate Legal Notices; however, if the Program has interactive\n    interfaces that do not display Appropriate Legal Notices, your\n    work need not make them do so.\n\n  A compilation of a covered work with other separate and independent\nworks, which are not by their nature extensions of the covered work,\nand which are not combined with it such as to form a larger program,\nin or on a volume of a storage or distribution medium, is called an\n\"aggregate\" if the compilation and its resulting copyright are not\nused to limit the access or legal rights of the compilation's users\nbeyond what the individual works permit.  Inclusion of a covered work\nin an aggregate does not cause this License to apply to the other\nparts of the aggregate.\n\n  6. Conveying Non-Source Forms.\n\n  You may convey a covered work in object code form under the terms\nof sections 4 and 5, provided that you also convey the\nmachine-readable Corresponding Source under the terms of this License,\nin one of these ways:\n\n    a) Convey the object code in, or embodied in, a physical product\n    (including a physical distribution medium), accompanied by the\n    Corresponding Source fixed on a durable physical medium\n    customarily used for software interchange.\n\n    b) Convey the object code in, or embodied in, a physical product\n    (including a physical distribution medium), accompanied by a\n    written offer, valid for at least three years and valid for as\n    long as you offer spare parts or customer support for that product\n    model, to give anyone who possesses the object code either (1) a\n    copy of the Corresponding Source for all the software in the\n    product that is covered by this License, on a durable physical\n    medium customarily used for software interchange, for a price no\n    more than your reasonable cost of physically performing this\n    conveying of source, or (2) access to copy the\n    Corresponding Source from a network server at no charge.\n\n    c) Convey individual copies of the object code with a copy of the\n    written offer to provide the Corresponding Source.  This\n    alternative is allowed only occasionally and noncommercially, and\n    only if you received the object code with such an offer, in accord\n    with subsection 6b.\n\n    d) Convey the object code by offering access from a designated\n    place (gratis or for a charge), and offer equivalent access to the\n    Corresponding Source in the same way through the same place at no\n    further charge.  You need not require recipients to copy the\n    Corresponding Source along with the object code.  If the place to\n    copy the object code is a network server, the Corresponding Source\n    may be on a different server (operated by you or a third party)\n    that supports equivalent copying facilities, provided you maintain\n    clear directions next to the object code saying where to find the\n    Corresponding Source.  Regardless of what server hosts the\n    Corresponding Source, you remain obligated to ensure that it is\n    available for as long as needed to satisfy these requirements.\n\n    e) Convey the object code using peer-to-peer transmission, provided\n    you inform other peers where the object code and Corresponding\n    Source of the work are being offered to the general public at no\n    charge under subsection 6d.\n\n  A separable portion of the object code, whose source code is excluded\nfrom the Corresponding Source as a System Library, need not be\nincluded in conveying the object code work.\n\n  A \"User Product\" is either (1) a \"consumer product\", which means any\ntangible personal property which is normally used for personal, family,\nor household purposes, or (2) anything designed or sold for incorporation\ninto a dwelling.  In determining whether a product is a consumer product,\ndoubtful cases shall be resolved in favor of coverage.  For a particular\nproduct received by a particular user, \"normally used\" refers to a\ntypical or common use of that class of product, regardless of the status\nof the particular user or of the way in which the particular user\nactually uses, or expects or is expected to use, the product.  A product\nis a consumer product regardless of whether the product has substantial\ncommercial, industrial or non-consumer uses, unless such uses represent\nthe only significant mode of use of the product.\n\n  \"Installation Information\" for a User Product means any methods,\nprocedures, authorization keys, or other information required to install\nand execute modified versions of a covered work in that User Product from\na modified version of its Corresponding Source.  The information must\nsuffice to ensure that the continued functioning of the modified object\ncode is in no case prevented or interfered with solely because\nmodification has been made.\n\n  If you convey an object code work under this section in, or with, or\nspecifically for use in, a User Product, and the conveying occurs as\npart of a transaction in which the right of possession and use of the\nUser Product is transferred to the recipient in perpetuity or for a\nfixed term (regardless of how the transaction is characterized), the\nCorresponding Source conveyed under this section must be accompanied\nby the Installation Information.  But this requirement does not apply\nif neither you nor any third party retains the ability to install\nmodified object code on the User Product (for example, the work has\nbeen installed in ROM).\n\n  The requirement to provide Installation Information does not include a\nrequirement to continue to provide support service, warranty, or updates\nfor a work that has been modified or installed by the recipient, or for\nthe User Product in which it has been modified or installed.  Access to a\nnetwork may be denied when the modification itself materially and\nadversely affects the operation of the network or violates the rules and\nprotocols for communication across the network.\n\n  Corresponding Source conveyed, and Installation Information provided,\nin accord with this section must be in a format that is publicly\ndocumented (and with an implementation available to the public in\nsource code form), and must require no special password or key for\nunpacking, reading or copying.\n\n  7. Additional Terms.\n\n  \"Additional permissions\" are terms that supplement the terms of this\nLicense by making exceptions from one or more of its conditions.\nAdditional permissions that are applicable to the entire Program shall\nbe treated as though they were included in this License, to the extent\nthat they are valid under applicable law.  If additional permissions\napply only to part of the Program, that part may be used separately\nunder those permissions, but the entire Program remains governed by\nthis License without regard to the additional permissions.\n\n  When you convey a copy of a covered work, you may at your option\nremove any additional permissions from that copy, or from any part of\nit.  (Additional permissions may be written to require their own\nremoval in certain cases when you modify the work.)  You may place\nadditional permissions on material, added by you to a covered work,\nfor which you have or can give appropriate copyright permission.\n\n  Notwithstanding any other provision of this License, for material you\nadd to a covered work, you may (if authorized by the copyright holders of\nthat material) supplement the terms of this License with terms:\n\n    a) Disclaiming warranty or limiting liability differently from the\n    terms of sections 15 and 16 of this License; or\n\n    b) Requiring preservation of specified reasonable legal notices or\n    author attributions in that material or in the Appropriate Legal\n    Notices displayed by works containing it; or\n\n    c) Prohibiting misrepresentation of the origin of that material, or\n    requiring that modified versions of such material be marked in\n    reasonable ways as different from the original version; or\n\n    d) Limiting the use for publicity purposes of names of licensors or\n    authors of the material; or\n\n    e) Declining to grant rights under trademark law for use of some\n    trade names, trademarks, or service marks; or\n\n    f) Requiring indemnification of licensors and authors of that\n    material by anyone who conveys the material (or modified versions of\n    it) with contractual assumptions of liability to the recipient, for\n    any liability that these contractual assumptions directly impose on\n    those licensors and authors.\n\n  All other non-permissive additional terms are considered \"further\nrestrictions\" within the meaning of section 10.  If the Program as you\nreceived it, or any part of it, contains a notice stating that it is\ngoverned by this License along with a term that is a further\nrestriction, you may remove that term.  If a license document contains\na further restriction but permits relicensing or conveying under this\nLicense, you may add to a covered work material governed by the terms\nof that license document, provided that the further restriction does\nnot survive such relicensing or conveying.\n\n  If you add terms to a covered work in accord with this section, you\nmust place, in the relevant source files, a statement of the\nadditional terms that apply to those files, or a notice indicating\nwhere to find the applicable terms.\n\n  Additional terms, permissive or non-permissive, may be stated in the\nform of a separately written license, or stated as exceptions;\nthe above requirements apply either way.\n\n  8. Termination.\n\n  You may not propagate or modify a covered work except as expressly\nprovided under this License.  Any attempt otherwise to propagate or\nmodify it is void, and will automatically terminate your rights under\nthis License (including any patent licenses granted under the third\nparagraph of section 11).\n\n  However, if you cease all violation of this License, then your\nlicense from a particular copyright holder is reinstated (a)\nprovisionally, unless and until the copyright holder explicitly and\nfinally terminates your license, and (b) permanently, if the copyright\nholder fails to notify you of the violation by some reasonable means\nprior to 60 days after the cessation.\n\n  Moreover, your license from a particular copyright holder is\nreinstated permanently if the copyright holder notifies you of the\nviolation by some reasonable means, this is the first time you have\nreceived notice of violation of this License (for any work) from that\ncopyright holder, and you cure the violation prior to 30 days after\nyour receipt of the notice.\n\n  Termination of your rights under this section does not terminate the\nlicenses of parties who have received copies or rights from you under\nthis License.  If your rights have been terminated and not permanently\nreinstated, you do not qualify to receive new licenses for the same\nmaterial under section 10.\n\n  9. Acceptance Not Required for Having Copies.\n\n  You are not required to accept this License in order to receive or\nrun a copy of the Program.  Ancillary propagation of a covered work\noccurring solely as a consequence of using peer-to-peer transmission\nto receive a copy likewise does not require acceptance.  However,\nnothing other than this License grants you permission to propagate or\nmodify any covered work.  These actions infringe copyright if you do\nnot accept this License.  Therefore, by modifying or propagating a\ncovered work, you indicate your acceptance of this License to do so.\n\n  10. Automatic Licensing of Downstream Recipients.\n\n  Each time you convey a covered work, the recipient automatically\nreceives a license from the original licensors, to run, modify and\npropagate that work, subject to this License.  You are not responsible\nfor enforcing compliance by third parties with this License.\n\n  An \"entity transaction\" is a transaction transferring control of an\norganization, or substantially all assets of one, or subdividing an\norganization, or merging organizations.  If propagation of a covered\nwork results from an entity transaction, each party to that\ntransaction who receives a copy of the work also receives whatever\nlicenses to the work the party's predecessor in interest had or could\ngive under the previous paragraph, plus a right to possession of the\nCorresponding Source of the work from the predecessor in interest, if\nthe predecessor has it or can get it with reasonable efforts.\n\n  You may not impose any further restrictions on the exercise of the\nrights granted or affirmed under this License.  For example, you may\nnot impose a license fee, royalty, or other charge for exercise of\nrights granted under this License, and you may not initiate litigation\n(including a cross-claim or counterclaim in a lawsuit) alleging that\nany patent claim is infringed by making, using, selling, offering for\nsale, or importing the Program or any portion of it.\n\n  11. Patents.\n\n  A \"contributor\" is a copyright holder who authorizes use under this\nLicense of the Program or a work on which the Program is based.  The\nwork thus licensed is called the contributor's \"contributor version\".\n\n  A contributor's \"essential patent claims\" are all patent claims\nowned or controlled by the contributor, whether already acquired or\nhereafter acquired, that would be infringed by some manner, permitted\nby this License, of making, using, or selling its contributor version,\nbut do not include claims that would be infringed only as a\nconsequence of further modification of the contributor version.  For\npurposes of this definition, \"control\" includes the right to grant\npatent sublicenses in a manner consistent with the requirements of\nthis License.\n\n  Each contributor grants you a non-exclusive, worldwide, royalty-free\npatent license under the contributor's essential patent claims, to\nmake, use, sell, offer for sale, import and otherwise run, modify and\npropagate the contents of its contributor version.\n\n  In the following three paragraphs, a \"patent license\" is any express\nagreement or commitment, however denominated, not to enforce a patent\n(such as an express permission to practice a patent or covenant not to\nsue for patent infringement).  To \"grant\" such a patent license to a\nparty means to make such an agreement or commitment not to enforce a\npatent against the party.\n\n  If you convey a covered work, knowingly relying on a patent license,\nand the Corresponding Source of the work is not available for anyone\nto copy, free of charge and under the terms of this License, through a\npublicly available network server or other readily accessible means,\nthen you must either (1) cause the Corresponding Source to be so\navailable, or (2) arrange to deprive yourself of the benefit of the\npatent license for this particular work, or (3) arrange, in a manner\nconsistent with the requirements of this License, to extend the patent\nlicense to downstream recipients.  \"Knowingly relying\" means you have\nactual knowledge that, but for the patent license, your conveying the\ncovered work in a country, or your recipient's use of the covered work\nin a country, would infringe one or more identifiable patents in that\ncountry that you have reason to believe are valid.\n\n  If, pursuant to or in connection with a single transaction or\narrangement, you convey, or propagate by procuring conveyance of, a\ncovered work, and grant a patent license to some of the parties\nreceiving the covered work authorizing them to use, propagate, modify\nor convey a specific copy of the covered work, then the patent license\nyou grant is automatically extended to all recipients of the covered\nwork and works based on it.\n\n  A patent license is \"discriminatory\" if it does not include within\nthe scope of its coverage, prohibits the exercise of, or is\nconditioned on the non-exercise of one or more of the rights that are\nspecifically granted under this License.  You may not convey a covered\nwork if you are a party to an arrangement with a third party that is\nin the business of distributing software, under which you make payment\nto the third party based on the extent of your activity of conveying\nthe work, and under which the third party grants, to any of the\nparties who would receive the covered work from you, a discriminatory\npatent license (a) in connection with copies of the covered work\nconveyed by you (or copies made from those copies), or (b) primarily\nfor and in connection with specific products or compilations that\ncontain the covered work, unless you entered into that arrangement,\nor that patent license was granted, prior to 28 March 2007.\n\n  Nothing in this License shall be construed as excluding or limiting\nany implied license or other defenses to infringement that may\notherwise be available to you under applicable patent law.\n\n  12. No Surrender of Others' Freedom.\n\n  If conditions are imposed on you (whether by court order, agreement or\notherwise) that contradict the conditions of this License, they do not\nexcuse you from the conditions of this License.  If you cannot convey a\ncovered work so as to satisfy simultaneously your obligations under this\nLicense and any other pertinent obligations, then as a consequence you may\nnot convey it at all.  For example, if you agree to terms that obligate you\nto collect a royalty for further conveying from those to whom you convey\nthe Program, the only way you could satisfy both those terms and this\nLicense would be to refrain entirely from conveying the Program.\n\n  13. Use with the GNU Affero General Public License.\n\n  Notwithstanding any other provision of this License, you have\npermission to link or combine any covered work with a work licensed\nunder version 3 of the GNU Affero General Public License into a single\ncombined work, and to convey the resulting work.  The terms of this\nLicense will continue to apply to the part which is the covered work,\nbut the special requirements of the GNU Affero General Public License,\nsection 13, concerning interaction through a network will apply to the\ncombination as such.\n\n  14. Revised Versions of this License.\n\n  The Free Software Foundation may publish revised and/or new versions of\nthe GNU General Public License from time to time.  Such new versions will\nbe similar in spirit to the present version, but may differ in detail to\naddress new problems or concerns.\n\n  Each version is given a distinguishing version number.  If the\nProgram specifies that a certain numbered version of the GNU General\nPublic License \"or any later version\" applies to it, you have the\noption of following the terms and conditions either of that numbered\nversion or of any later version published by the Free Software\nFoundation.  If the Program does not specify a version number of the\nGNU General Public License, you may choose any version ever published\nby the Free Software Foundation.\n\n  If the Program specifies that a proxy can decide which future\nversions of the GNU General Public License can be used, that proxy's\npublic statement of acceptance of a version permanently authorizes you\nto choose that version for the Program.\n\n  Later license versions may give you additional or different\npermissions.  However, no additional obligations are imposed on any\nauthor or copyright holder as a result of your choosing to follow a\nlater version.\n\n  15. Disclaimer of Warranty.\n\n  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY\nAPPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT\nHOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM \"AS IS\" WITHOUT WARRANTY\nOF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,\nTHE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR\nPURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM\nIS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF\nALL NECESSARY SERVICING, REPAIR OR CORRECTION.\n\n  16. Limitation of Liability.\n\n  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING\nWILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS\nTHE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY\nGENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE\nUSE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF\nDATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD\nPARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),\nEVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF\nSUCH DAMAGES.\n\n  17. Interpretation of Sections 15 and 16.\n\n  If the disclaimer of warranty and limitation of liability provided\nabove cannot be given local legal effect according to their terms,\nreviewing courts shall apply local law that most closely approximates\nan absolute waiver of all civil liability in connection with the\nProgram, unless a warranty or assumption of liability accompanies a\ncopy of the Program in return for a fee.\n\n                     END OF TERMS AND CONDITIONS\n\n            How to Apply These Terms to Your New Programs\n\n  If you develop a new program, and you want it to be of the greatest\npossible use to the public, the best way to achieve this is to make it\nfree software which everyone can redistribute and change under these terms.\n\n  To do so, attach the following notices to the program.  It is safest\nto attach them to the start of each source file to most effectively\nstate the exclusion of warranty; and each file should have at least\nthe \"copyright\" line and a pointer to where the full notice is found.\n\n    <one line to give the program's name and a brief idea of what it does.>\n    Copyright (C) <year>  <name of author>\n\n    This program is free software: you can redistribute it and/or modify\n    it under the terms of the GNU General Public License as published by\n    the Free Software Foundation, either version 3 of the License, or\n    (at your option) any later version.\n\n    This program is distributed in the hope that it will be useful,\n    but WITHOUT ANY WARRANTY; without even the implied warranty of\n    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the\n    GNU General Public License for more details.\n\n    You should have received a copy of the GNU General Public License\n    along with this program.  If not, see <http://www.gnu.org/licenses/>.\n\nAlso add information on how to contact you by electronic and paper mail.\n\n  If the program does terminal interaction, make it output a short\nnotice like this when it starts in an interactive mode:\n\n    <program>  Copyright (C) <year>  <name of author>\n    This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.\n    This is free software, and you are welcome to redistribute it\n    under certain conditions; type `show c' for details.\n\nThe hypothetical commands `show w' and `show c' should show the appropriate\nparts of the General Public License.  Of course, your program's commands\nmight be different; for a GUI interface, you would use an \"about box\".\n\n  You should also get your employer (if you work as a programmer) or school,\nif any, to sign a \"copyright disclaimer\" for the program, if necessary.\nFor more information on this, and how to apply and follow the GNU GPL, see\n<http://www.gnu.org/licenses/>.\n\n  The GNU General Public License does not permit incorporating your program\ninto proprietary programs.

    "content": "Janus WebRTC Server\n===================\n[![License: GPL v3](https://img.shields.io/badge/License-GPLv3-brightgreen.svg)](COPYING)\n![janus-ci](https://github.com/meetecho/janus-gateway/workflows/janus-ci/badge.svg)\n[![Coverity Scan Build Status](https://scan.coverity.com/projects/13265/badge.svg)](https://scan.coverity.com/projects/meetecho-janus-gateway)\n[![Fuzzing Status](https://oss-fuzz-build-logs.storage.googleapis.com/badges/janus-gateway.svg)](https://bugs.chromium.org/p/oss-fuzz/issues/list?sort=-opened&can=1&q=proj:janus-gateway)\n\nJanus is an open source, general purpose, WebRTC server designed and developed by [Meetecho](https://www.meetecho.com). This version of the server is tailored for Linux systems, although it can be compiled for, and installed on, MacOS machines as well. Windows is not supported, but if that's a requirement, Janus is known to work in the \"Windows Subsystem for Linux\" on Windows 10: do **NOT** trust repos that provide .exe builds of Janus, they are not official and will not be supported.\n\nFor some online demos and documentations, make sure you pay the [project website](https://janus.conf.meetecho.com/) a visit!\n\n> **Note well:** this is the main branch for the `multistream` version of Janus, which is the new version. If you want to check the legacy version of Janus instead (i.e., `0.x`, a.k.a. \"legacy\") click [here](https://github.com/meetecho/janus-gateway/tree/0.x) instead.\n\nIf you have questions on Janus, or wish to discuss Janus with us and other users, please join our [Community](https://janus.discourse.group/). If you encounter bugs, please submit an issue on [GitHub](https://github.com/meetecho/janus-gateway/issues): make sure you read the [guidelines](.github/CONTRIBUTING.md) before opening an issue or a pull request, though.\n\n\n## Dependencies\nTo install it, you'll need to satisfy the following dependencies:\n\n* [GLib](https://docs.gtk.org/glib/)\n* [zlib](https://zlib.net/)\n* [pkg-config](https://www.freedesktop.org/wiki/Software/pkg-config/)\n* [Jansson](https://github.com/akheron/jansson)\n* [libconfig](https://hyperrealm.github.io/libconfig/)\n* [libnice](https://libnice.freedesktop.org/) (at least v0.1.16 suggested, v0.1.18 recommended)\n* [OpenSSL](https://www.openssl.org/) (at least v1.0.1e)\n* [libsrtp](https://github.com/cisco/libsrtp) (at least v2.x suggested)\n\nThese are optional dependencies, depending on which features you're interested in:\n\n* [usrsctp](https://github.com/sctplab/usrsctp) (only needed if you are interested in Data Channels)\n* [libmicrohttpd](https://www.gnu.org/software/libmicrohttpd/) (at least v0.9.59; only needed if you are interested in REST support for the Janus API)\n* [libwebsockets](https://libwebsockets.org/) (at least v4.x suggested; only needed if you are interested in WebSockets support for the Janus API)\n* [cmake](https://www.cmake.org/) (only needed if you are interested in WebSockets and/or BoringSSL support, as they make use of it)\n* [rabbitmq-c](https://github.com/alanxz/rabbitmq-c) (only needed if you are interested in RabbitMQ support for the Janus API or events)\n* [paho.mqtt.c](https://eclipse.org/paho/clients/c) (only needed if you are interested in MQTT support for the Janus API or events)\n* [nanomsg](https://nanomsg.org/) (only needed if you are interested in Nanomsg support for the Janus API)\n* [libcurl](https://curl.haxx.se/libcurl/) (only needed if you are interested in the TURN REST API support)\n\nA couple of plugins depend on a few more libraries (you only need to install the ones for the plugins you need):\n\n* [Sofia-SIP](https://github.com/freeswitch/sofia-sip) (only needed for the SIP plugin)\n* [libopus](https://opus-codec.org/) (only needed for the AudioBridge plugin)\n* [libogg](https://xiph.org/ogg/) (needed for the recordings post-processor, and optionally AudioBridge and Streaming plugins)\n* [libcurl](https://curl.haxx.se/libcurl/) (only needed if you are interested in RTSP support in the Streaming plugin or in the sample Event Handler plugin)\n* [Lua](https://www.lua.org/download.html) (only needed for the Lua plugin)\n* [Duktape](https://duktape.org/) (only needed for the Duktape plugin)\n\n\nAll of those libraries are usually available on most of the most common distributions. Installing these libraries on a recent Fedora, for instance, is very simple:\n\n    yum install libmicrohttpd-devel jansson-devel \\\n       openssl-devel libsrtp-devel sofia-sip-devel glib2-devel \\\n       opus-devel libogg-devel libcurl-devel pkgconfig \\\n       libconfig-devel libtool autoconf automake\n\nNotice that you may have to `yum install epel-release` as well if you're attempting an installation on a CentOS machine instead.\n\nOn Ubuntu or Debian, it would require something like this:\n\n\tapt install libmicrohttpd-dev libjansson-dev \\\n\t\tlibssl-dev libsofia-sip-ua-dev libglib2.0-dev \\\n\t\tlibopus-dev libogg-dev libcurl4-openssl-dev liblua5.3-dev \\\n\t\tlibconfig-dev pkg-config libtool automake\n\n* *Note:* please notice that libopus may not be available out of the box on your distro. In that case, you'll have to [install it manually](https://www.opus-codec.org).\n\nWhile `libnice` is typically available in most distros as a package, the version available out of the box in Ubuntu is known to cause problems. As such, we always recommend manually compiling and installing the master version of libnice.\nTo build libnice, you need Python 3, Meson and Ninja:\n\n\tgit clone https://gitlab.freedesktop.org/libnice/libnice\n\tcd libnice\n\tmeson --prefix=/usr build && ninja -C build && sudo ninja -C build install\n\n* *Note:* Make sure you remove the distro version first, or you'll cause conflicts between the installations. In case you want to keep both for some reason, for custom installations of libnice you can also run `pkg-config --cflags --libs nice` to make sure Janus can find the right installation. If that fails, you may need to set the `PKG_CONFIG_PATH` environment variable prior to compiling Janus, e.g., `export PKG_CONFIG_PATH=/path/to/libnice/lib/pkgconfig`\n\nIn case you're interested in compiling the sample Event Handler plugin, you'll need to install the development version of libcurl as well (usually `libcurl-devel` on Fedora/CentOS, `libcurl4-openssl-dev` on Ubuntu/Debian).\n\nIf your distro ships a pre-1.5 version of libsrtp, you'll have to uninstall that version and [install 1.5.x, 1.6.x or 2.x manually](https://github.com/cisco/libsrtp/releases). In fact, 1.4.x is known to cause several issues with WebRTC. While 1.5.x is supported, we recommend installing 2.x instead. Notice that the following steps are for version 2.2.0, but there may be more recent versions available:\n\n\twget https://github.com/cisco/libsrtp/archive/v2.2.0.tar.gz\n\ttar xfv v2.2.0.tar.gz\n\tcd libsrtp-2.2.0\n\t./configure --prefix=/usr --enable-openssl\n\tmake shared_library && sudo make install\n\nNotice that the `--enable-openssl` part is _important_, as it's needed for AES-GCM support. As an alternative, you can also pass `--enable-nss` to have libsrtp use NSS instead of OpenSSL. A failure to configure libsrtp with either might cause undefined references when starting Janus, as we'd be trying to use methods that aren't there.\n\nThe Janus configure script autodetects which one you have installed and links to the correct library automatically, choosing 2.x if both are installed. If you want 1.5 or 1.6 to be picked (which is NOT recommended), pass `--disable-libsrtp2` when configuring Janus to force it to use the older version instead.\n\n* *Note:* when installing libsrtp, no matter which version, you may need to pass `--libdir=/usr/lib64` to the configure script if you're installing on a x86_64 distribution.\n\nIf you want to make use of BoringSSL instead of OpenSSL (e.g., because you want to take advantage of `--enable-dtls-settimeout`), you'll have to manually install it to a specific location. Use the following steps:\n\n\tgit clone https://boringssl.googlesource.com/boringssl\n\tcd boringssl\n\t# Don't barf on errors\n\tsed -i s/\" -Werror\"//g CMakeLists.txt\n\t# Build\n\tmkdir -p build\n\tcd build\n\tcmake -DCMAKE_INSTALL_PREFIX=/opt/boringssl -DCMAKE_CXX_FLAGS=\"-lrt\" ..\n\tmake\n\tsudo make install\n\nOnce the library is installed, you'll have to pass an additional `--enable-boringssl` flag to the configure script, as by default Janus will be built assuming OpenSSL will be used. By default, Janus expects BoringSSL to be installed in `/opt/boringssl` -- if it's installed in another location, pass the path to the configure script as such: `--enable-boringssl=/path/to/boringssl` If you were using OpenSSL and want to switch to BoringSSL, make sure you also do a `make clean` in the Janus folder before compiling with the new BoringSSL support. If you enabled BoringSSL support and also want Janus to detect and react to DTLS timeouts with faster retransmissions, then pass `--enable-dtls-settimeout` to the configure script too.\n\n* *Note:* as explained in [this issue](https://github.com/meetecho/janus-gateway/issues/3456), building Janus with more recent versions of BoringSSL may require you to pass a `CCLD=c++` for any `make` command to build Janus itself.\n\nFor what concerns usrsctp, which is needed for Data Channels support, it is usually not available in repositories, so if you're interested in them (support is optional) you'll have to install it manually. It is a pretty easy and standard process:\n\n\tgit clone https://github.com/sctplab/usrsctp\n\tcd usrsctp\n\t./bootstrap\n\t./configure --prefix=/usr --disable-programs --disable-inet --disable-inet6\n\tmake && sudo make install\n\n* *Note:* you may need to pass `--libdir=/usr/lib64` to the configure script if you're installing on a x86_64 distribution.\n\nThe same applies for libwebsockets, which is needed for the optional WebSockets support. If you're interested in supporting WebSockets to control Janus, as an alternative (or replacement) to the default plain HTTP REST API, you'll have to install it manually:\n\n\tgit clone https://libwebsockets.org/repo/libwebsockets\n\tcd libwebsockets\n\t# If you want the stable version of libwebsockets, uncomment the next line\n\t# git checkout v4.3-stable\n\tmkdir build\n\tcd build\n\t# See https://github.com/meetecho/janus-gateway/issues/732 re: LWS_MAX_SMP\n\t# See https://github.com/meetecho/janus-gateway/issues/2476 re: LWS_WITHOUT_EXTENSIONS\n\tcmake -DLWS_MAX_SMP=1 -DLWS_WITHOUT_EXTENSIONS=0 -DCMAKE_INSTALL_PREFIX:PATH=/usr -DCMAKE_C_FLAGS=\"-fpic\" ..\n\tmake && sudo make install\n\n* *Note:* if libwebsockets.org is unreachable for any reason, replace the first line with this:\n\n\tgit clone https://github.com/warmcat/libwebsockets.git\n\nThe same applies for Eclipse Paho MQTT C client library, which is needed for the optional MQTT support. If you're interested in integrating MQTT channels as an alternative (or replacement) to HTTP and/or WebSockets to control Janus, or as a carrier of Janus Events, you can install the latest version with the following steps:\n\n\tgit clone https://github.com/eclipse/paho.mqtt.c.git\n\tcd paho.mqtt.c\n\tmake && sudo make install\n\n* *Note:* you may want to set up a different install path for the library, to achieve that, replace the last command by 'sudo prefix=/usr make install'.\n\nIn case you're interested in Nanomsg support, you'll need to install the related C library. It is usually available as an easily installable package in pretty much all repositories. The following is an example on how to install it on Ubuntu:\n\n\taptitude install libnanomsg-dev\n\nFinally, the same can be said for rabbitmq-c as well, which is needed for the optional RabbitMQ support. In fact, several different versions of the library can be found, and the versions usually available in most distribution repositories are not up-do-date with respect to the current state of the development. As such, if you're interested in integrating RabbitMQ queues as an alternative (or replacement) to HTTP and/or WebSockets to control Janus, you can install the latest version with the following steps:\n\n\tgit clone https://github.com/alanxz/rabbitmq-c\n\tcd rabbitmq-c\n\tgit submodule init\n\tgit submodule update\n\tmkdir build && cd build\n\tcmake -DCMAKE_INSTALL_PREFIX=/usr ..\n\tmake && sudo make install\n\n* *Note:* you may need to pass `--libdir=/usr/lib64` to the configure script if you're installing on a x86_64 distribution.\n\nTo conclude, should you be interested in building the Janus documentation as well, you'll need some additional tools too:\n\n* [Doxygen](https://www.doxygen.org)\n* [Graphviz](https://www.graphviz.org/)\n\nOn Fedora:\n\n\tyum install doxygen graphviz\n\nOn Ubuntu/Debian:\n\n\taptitude install doxygen graphviz\n\n\n## Compile\nOnce you have installed all the dependencies, get the code:\n\n\tgit clone https://github.com/meetecho/janus-gateway.git\n\tcd janus-gateway\n\nThen just use:\n\n\tsh autogen.sh\n\nto generate the configure file. After that, configure and compile as usual to start the whole compilation process:\n\n\t./configure --prefix=/opt/janus\n\tmake\n\tmake install\n\nSince Janus requires configuration files for both the core and its modules in order to work, you'll probably also want to install the default configuration files to use, which you can do this way:\n\n\tmake configs\n\nRemember to only do this once, or otherwise a subsequent `make configs` will overwrite any configuration file you may have modified in the meanwhile.\n\nIf you've installed the above libraries but are not interested, for instance, in Data Channels, WebSockets, MQTT and/or RabbitMQ, you can disable them when configuring:\n\n\t./configure --disable-websockets --disable-data-channels --disable-rabbitmq --disable-mqtt\n\nThere are configuration flags for pretty much all external modules and many of the features, so you may want to issue a `./configure --help` to dig through the available options. A summary of what's going to be built will always appear after you do a configure, allowing you to double check if what you need and don't need is there.\n\nIf Doxygen and graphviz are available, the process can also build the documentation for you. By default the compilation process will not try to build the documentation, so if you instead prefer to build it, use the `--enable-docs` configuration option:\n\n\t./configure --enable-docs\n\nYou can also selectively enable/disable other features (e.g., specific plugins you don't care about, or whether or not you want to build the recordings post-processor). Use the --help option when configuring for more info.\n\n### Building on FreeBSD\n* *Note*: rtp_forward of streams only works streaming to IPv6,\nbecause of #2051 and thus the feature is not supported on FreeBSD at the moment.\n\nWhen building on FreeBSD you can install the depencencies from ports or packages, here only pkg method is used. You also need to use `gmake` instead of `make`,\nsince it is a GNU makefile. `./configure` can be run without arguments since the default prefix is `/usr/local` which is your default `LOCALBASE`.\nNote that the `configure.ac` is coded to use openssl in base. If you wish to use openssl from ports or any other ssl you must change `configure.ac` accordingly.\n\n\tpkg install libsrtp2 libusrsctp jansson libnice libmicrohttpd libwebsockets curl opus sofia-sip libogg jansson libnice libconfig \\\n        libtool gmake autoconf autoconf-wrapper glib\n\n\n### Building on MacOS\nWhile most of the above instructions will work when compiling Janus on MacOS as well, there are a few aspects to highlight when doing that.\n\nFirst of all, you can use `brew` to install most of the dependencies:\n\n\tbrew install jansson libnice openssl srtp libusrsctp libmicrohttpd \\\n\t\tlibwebsockets cmake rabbitmq-c sofia-sip opus libogg curl glib \\\n\t\tlibconfig pkg-config autoconf automake libtool\n\nFor what concerns libwebsockets, though, make sure that the installed version is higher than `2.4.1`, or you might encounter the problems described in [this post](https://groups.google.com/forum/#!topic/meetecho-janus/HsFaEXBz4Cg). If `brew` doesn't provide a more recent version, you'll have to install the library manually.\n\nNotice that you may need to provide a custom `prefix` and `PKG_CONFIG_PATH` when configuring Janus as well, e.g.:\n\n\t./configure --prefix=/usr/local/janus PKG_CONFIG_PATH=/usr/local/opt/openssl/lib/pkgconfig\n\nEverything else works exactly the same way as on Linux.\n\n## Configure and start\nTo start the server, you can use the `janus` executable. There are several things you can configure, either in a configuration file:\n\n\t<installdir>/etc/janus/janus.jcfg\n\nor on the command line:\n\n\t<installdir>/bin/janus --help\n\n\tUsage: janus [OPTIONS]...\n\n\t-h, --help                    Print help and exit\n\t-V, --version                 Print version and exit\n\t-b, --daemon                  Launch Janus in background as a daemon\n                                  (default=off)\n\t-p, --pid-file=path           Open the specified PID file when starting Janus\n                                  (default=none)\n\t-N, --disable-stdout          Disable stdout based logging  (default=off)\n\t-L, --log-file=path           Log to the specified file (default=stdout only)\n\t-H  --cwd-path                Working directory for Janus daemon process\n\t                              (default=/)\n\t-i, --interface=ipaddress     Interface to use (will be the public IP)\n\t-P, --plugins-folder=path     Plugins folder (default=./plugins)\n\t-C, --config=filename         Configuration file to use\n\t-F, --configs-folder=path     Configuration files folder (default=./conf)\n\t-c, --cert-pem=filename       DTLS certificate\n\t-k, --cert-key=filename       DTLS certificate key\n\t-K, --cert-pwd=text           DTLS certificate key passphrase (if needed)\n\t-S, --stun-server=address:port\n                                  STUN server(:port) to use, if needed (e.g.,\n                                  Janus behind NAT, default=none)\n\t-1, --nat-1-1=ip              Public IP to put in all host candidates,\n                                  assuming a 1:1 NAT is in place (e.g., Amazon\n                                  EC2 instances, default=none)\n\t-2, --keep-private-host       When nat-1-1 is used (e.g., Amazon EC2\n                                  instances), don't remove the private host,\n                                  but keep both to simulate STUN  (default=off)\n\t-E, --ice-enforce-list=list   Comma-separated list of the only interfaces to\n                                  use for ICE gathering; partial strings are\n                                  supported (e.g., eth0 or eno1,wlan0,\n                                  default=none)\n\t-X, --ice-ignore-list=list    Comma-separated list of interfaces or IP\n                                  addresses to ignore for ICE gathering;\n                                  partial strings are supported (e.g.,\n                                  vmnet8,192.168.0.1,10.0.0.1 or\n                                  vmnet,192.168., default=vmnet)\n\t-6, --ipv6-candidates         Whether to enable IPv6 candidates or not\n                                  (experimental)  (default=off)\n\t-O, --ipv6-link-local         Whether IPv6 link-local candidates should be\n                                  gathered as well  (default=off)\n\t-f, --full-trickle            Do full-trickle instead of half-trickle\n                                  (default=off)\n\t-I, --ice-lite                Whether to enable the ICE Lite mode or not\n                                  (default=off)\n\t-T, --ice-tcp                 Whether to enable ICE-TCP or not (warning: only\n                                  works with ICE Lite)\n                                  (default=off)\n\t-Q, --min-nack-queue=number   Minimum size of the NACK queue (in ms) per user\n                                  for retransmissions, no matter the RTT\n\t-t, --no-media-timer=number   Time (in s) that should pass with no media\n                                  (audio or video) being received before Janus\n                                  notifies you about this\n\t-W, --slowlink-threshold=number\n                                  Number of lost packets (per s) that should\n                                  trigger a 'slowlink' Janus API event to users\n                                  (default=0, feature disabled)\n\t-r, --rtp-port-range=min-max  Port range to use for RTP/RTCP (only available\n\t\t\t\t\t\t\t\t  if the installed libnice supports it)\n\t-B, --twcc-period=number      How often (in ms) to send TWCC feedback back to\n                                  senders, if negotiated (default=200ms)\n\t-n, --server-name=name        Public name of this Janus instance\n                                  (default=MyJanusInstance)\n\t-s, --session-timeout=number  Session timeout value, in seconds (default=60)\n\t-m, --reclaim-session-timeout=number\n                                  Reclaim session timeout value, in seconds\n                                  (default=0)\n\t-d, --debug-level=1-7         Debug/logging level (0=disable debugging,\n                                  7=maximum debug level; default=4)\n\t-D, --debug-timestamps        Enable debug/logging timestamps  (default=off)\n\t-o, --disable-colors          Disable color in the logging  (default=off)\n\t-M, --debug-locks             Enable debugging of locks/mutexes (very\n                                  verbose!)

(default=off)\n\n\nOptions passed through the command line have the precedence on those specified in the configuration file. To start the server, simply run:\n\n\t<installdir>/bin/janus\n\nThis will start the server, and have it look at the configuration file.\n\nMake sure you have a look at all of the configuration files, to tailor Janus to your specific needs: each configuration file is documented, so it shouldn't be hard to make changes according to your requirements. The repo comes with some defaults (assuming you issues `make configs` after installing the server) that tend to make sense for generic deployments, and also includes some sample configurations for all the plugins (e.g., web servers to listen on, conference rooms to create, streaming mountpoints to make available at startup, etc.).\n\nTo test whether it's working correctly, you can use the demos provided with this package in the `html` folder: these are exactly the same demos available online on the [project website](https://janus.conf.meetecho.com/). Just copy the file it contains in a webserver, or use a userspace webserver to serve the files in the `html` folder (e.g., with php or python), and open the `index.html` page in either Chrome or Firefox. A list of demo pages exploiting the different plugins will be available. Remember to edit the transport/port details in the demo JavaScript files if you changed any transport-related configuration from its defaults. Besides, the demos refer to the pre-configured plugin resources, so if you add some new resources (e.g., a new videoconference) you may have to tweak the demo pages to actually use them.\n\n## Documentation\nJanus is thoroughly documented. You can find the current documentation, automatically generated with Doxygen, on the [project website](https://janus.conf.meetecho.com/docs/).\n\n## Help us!\nAny thought, feedback or (hopefully not!) insult is welcome!\n\nDeveloped by [@meetecho](https://github.com/meetecho)\n"

In case STUN is not enough and\n# this is needed (it shouldn't), you can also configure Janus to use a\n# TURN server# please notice that this does NOT refer to TURN usage in\n# browsers, but in the gathering of relay candidates by Janus itself,\n# e.g., if you want to limit the ports used by a Janus instance on a\n# private machine. Furthermore, you can choose whether Janus should be\n# configured to do full-trickle (Janus also trickles its candidates to\n# users) rather than the default half-trickle (Janus supports trickle\n# candidates from users, but sends its own within the SDP), and whether\n# it should work in ICE-Lite mode (by default it doesn't). If libnice is\n# at least 0.1.15, you can choose which ICE nomination mode to use: valid\n# values are \"regular\" and \"aggressive\" (the default depends on the libnice\n# version itself; if we can set it, we set aggressive nomination). If\n# libnice is at least 0.1.19, you can enable consent freshness checks for\n# PeerConnections as well: this will issue regular checks to check whether\n# or not the WebRTC peer isn't available anymore. Enabling consent freshness\n# will automatically also enable using connectivity checks as keep-alives, which\n# might help detecting when a peer is no longer available (notice that\n# current libnice master is breaking connections after 50 seconds when\n# keepalive-conncheck is being used, so if you want to use it, better\n# sticking to 0.1.18 until the issue is addressed upstream).

This means that, for video\n# streams, new viewers may initially start receiving frames they cannot\n# decode right away, since they'd refer to keyframes that were sent before\n# they joined. In such scenarios, they'd have to wait until the next keyframe\n# arrives before video can be decoded and displayed, which could take a\n# while depending on the frequency of keyframes encoded by the source.\n# For forwarded streams (e.g., from the VideoRoom) this can be easily\n# addressed by using the RTCP support. For sources that can't or won't\n# honour dynamic keyframe requests, a partial and experimental solution\n# might be storing the latest keyframe and the following deltas, to send\n# to new viewers before new live packet are delivered. This feature can\n# be enabled in the Streaming plugin using the 'bufferkf_ms' and/or\n# the 'bufferkf_bytes' properties, which configure how many milliseconds\n# or how many bytes (in total) should be stored any time a keyframe is\n# received: data exceeding those limits won't be stored, until a new\n# keyframe arrives. The two properties are not mutually exclusive, and\n# can be configured at the same time: in that case, the first one that\n# hits the limit stops the buffering of the current keyframe. Notice\n# that, again, this feature should be considered highly experimental,\n# and that it comes with a few considerable drawbacks: the most obvious\n# one is that, depending on how many packets were stored, new viewers\n# may be hit with a considerable burst of data as soon as they connect,\n# which may negatively impact performance or even cause issues of its own.\n# Also notice that this is a global, and not per-stream, feature: this\n# means that if you create a mountpoint with two video streams, the\n# feature will impact both of them, and both streams will have a buffer\n# of their own. This also works for RTSP mountpoints.\n#\tbufferkf_ms = how many milliseconds of packets to store, starting\n#\t\t\t\t\tfrom a new keyframe (default=0)\n#\tbufferkf_bytes = how many bytes of packets to store, starting\n#\t\t\t\t\tfrom a new keyframe (default=0)\n#\n# In case you want to use SRTP for your RTP-based mountpoint, you'll need\n# to configure the SRTP-related properties as well, namely the suite to\n# use for hashing (32 or 80) and the crypto information for decrypting\n# the stream (as a base64 encoded string the way SDES does it).

This page will only\n\t\t\t\t\t\twork as it is if you enabled the API (which is disabled by default)\n\t\t\t\t\t\tand you're using the default values. Edit the backend settings in\n\t\t\t\t\t\tthe <code>admin.js</code> JavaScript code to adapt it to your\n\t\t\t\t\t\tconfiguration if you changed anything.</p>\n\t\t\t\t\t\t<p>The <code>Server Info</code> tab, as the name suggests, provides\n\t\t\t\t\t\tyou with a view of the information related to the Janus instance\n\t\t\t\t\t\tyou're using, e.g., in terms of the features that have been enabled,\n\t\t\t\t\t\tthe modules that are available and so on. That's the same info you'd\n\t\t\t\t\t\tget contacting the Janus API at the <code>/janus/info</code> backend.</p>\n\t\t\t\t\t\t<p>The <code>Settings</code> tab instead allows you to inspect a\n\t\t\t\t\t\tfew of the current settings in Janus (e.g., debug level and so on)\n\t\t\t\t\t\tand provides you with a way to change them dynamically.</p>\n\t\t\t\t\t\t<p>The <code>Plugins</code> tab presents the list of media plugins\n\t\t\t\t\t\tavailable in this Janus instance, and allows you to interact with\n\t\t\t\t\t\tthem, assuming they implement the <code>handle_admin_message</code> API.\n\t\t\t\t\t\tThe <code>Transports</code> tab does the same for transport plugins,\n\t\t\t\t\t\tand allows you to send requests to tweak the behaviour of the plugin\n\t\t\t\t\t\tor query its internal state, assuming they support this somehow.</p>\n\t\t\t\t\t\t<p>The <code>Handles</code> tab allows you to browse the currently active sessions\n\t\t\t\t\t\tand handles in Janus. Selecting a specific handle will provide you\n\t\t\t\t\t\twith all the current info related to it, including plugin it is\n\t\t\t\t\t\tattached to, any plugin specific information that may be relevant,\n\t\t\t\t\t\tICE/DTLS states, amount of data being exchanged and so on. This\n\t\t\t\t\t\tsection is especially helpful when you want to debug issues with\n\t\t\t\t\t\ta PeerConnection: you can find more details in\n\t\t\t\t\t\t<a href=\"http://www.meetecho.com/blog/understanding-the-janus-admin-api/\" target=\"_blank\">this blog post</a>.</p>\n\t\t\t\t\t\t<p>Finally, the <code>Stored Tokens</code> tab allows you to list\n\t\t\t\t\t\texisting authentication tokens, create new ones, associate plugin\n\t\t\t\t\t\tpermissions and the like.

The <code>canvas</code> element is then used\n\t\t\t\t\t\tas the actual source of media for our PeerConnection, which means the\n\t\t\t\t\t\tvideo we get back from the EchoTest plugin should reflect the\n\t\t\t\t\t\ttweaks we've made on the stream.</p>\n\t\t\t\t\t\t<p>Notice that this is a very naive implementation, with many\n\t\t\t\t\t\thardcoded assumptions about video resolution and other things, and may not\n\t\t\t\t\t\tperform very well either: it's only meant to showcase an interesting\n\t\t\t\t\t\tapproach that can be used for WebRTC, so you're encouraged to dig\n\t\t\t\t\t\tdeeper yourself to see how to make the <code>canvas</code>\n\t\t\t\t\t\tprocessing more efficient and cooler.

You're basically attached to yourself, and so your audio\n\t\t\t\t\t\tand video you send to Janus are echoed back to you. The same\n\t\t\t\t\t\tis done for RTCP packets as well, with the information properly updated.</p>\n\t\t\t\t\t\t<p>The demo also provides a few controls to manipulate the media\n\t\t\t\t\t\tbefore you send them. You can mute audio and video, for instance,\n\t\t\t\t\t\twhich will tell the server to drop the frames and not echo them\n\t\t\t\t\t\tback to you. You can also try and cap the bitrate: such control\n\t\t\t\t\t\twill tell the server to manipulate the RTCP REMB packets passing\n\t\t\t\t\t\tthrough, in order to simulate a bandwidth limitation. In case\n\t\t\t\t\t\tyou're interested in testing simulcasting or SVC, add a\n\t\t\t\t\t\t<code>?simulcast=true</code> (for simulcast) or <code>?svc=&lt;mode&gt;</code> (for SVC)\n\t\t\t\t\t\tquery string to the url of this page and reload it: buttons will appear\n\t\t\t\t\t\tto allow you to try and switch between lower and higher quality\n\t\t\t\t\t\tversions of the video you're capturing. Notice that you may have\n\t\t\t\t\t\tto increase the bandwidth indicator to have the higher quality\n\t\t\t\t\t\tversions appear, as the browser will not encode them otherwise.\n\t\t\t\t\t\tBesides, notice that simulcast will only work when using VP8 or H.264\n\t\t\t\t\t\t(or, if you're using a recent version of Chrome, VP9 and AV1 too),\n\t\t\t\t\t\twhile SVC will only work if you're using VP9 or AV1 on a browser that\n\t\t\t\t\t\tsupports setting the <code>scalabilityMode</code>.</p>\n\t\t\t\t\t\t<p>Finally, this demo also includes Data Channels: whatever you\n\t\t\t\t\t\twrite in the text box under your local video, will be sent via\n\t\t\t\t\t\tData Channels to the plugins, modified by adding a fixed prefix,\n\t\t\t\t\t\tand sent back to you in the text area below the remote video.</p>\n\t\t\t\t\t\t<div class=\"alert alert-info\">This demo, as all the others, for the\n\t\t\t\t\t\tsake of simplicity accesses the default devices you have available on\n\t\t\t\t\t\tyour machine.

More precisely, we downloaded a surround demo video from\n\t\t\t\t\t\t<a target=\"_blank\" href=\"https://www2.iis.fraunhofer.de/AAC/multichannel.html\">Fraunhofer's multichannel tests</a>\n\t\t\t\t\t\tand, using <a target=\"_blank\" href=\"https://developer.mozilla.org/en-US/docs/Web/API/HTMLMediaElement/captureStream\">captureStream</a>\n\t\t\t\t\t\ton the video element, get access to the MediaStream to send via WebRTC.\n\t\t\t\t\t\tAs a result, a surround audio/video stream is sent to the EchoTest plugin\n\t\t\t\t\t\tvia WebRTC, which echoes it back, allowing you to demonstrate how the surround\n\t\t\t\t\t\tproperties are preserved through the PeerConnection journey via Janus.\n\t\t\t\t\t\tThe file will loop back to the beginning when it ends, since it's quite short.</p>\n\t\t\t\t\t\t<p>Notice that you'll need a recent version of Chrome for this to work, since\n\t\t\t\t\t\tit's only implemented there and not really available publicly. As a matter of\n\t\t\t\t\t\tfact, Chrome will by default not offer multiopus support by default, and will\n\t\t\t\t\t\teven reject it when offered: it's up to you to munge the SDP to force multiopus\n\t\t\t\t\t\tsupport for a conversation. The <code>janus.js</code> library will <b>NOT</b>\n\t\t\t\t\t\tdo it for you: this demo uses the <code>customizeSdp</code> callback to mess\n\t\t\t\t\t\twith the SDP in an ugly way. In other contexts (e.g., VideoRoom subscribers)\n\t\t\t\t\t\tyou'll need to do something similar when creating the answer instead.</p>\n\t\t\t\t\t\t<p>Press the <code>Start</code> button above to launch the demo.</p>\n\t\t\t\t\t</div>\n\t\t\t\t</div>\n\t\t\t</div>\n\t\t\t<div class=\"container mt-4 hide\" id=\"videos\">\n\t\t\t\t<div class=\"row\">\n\t\t\t\t\t<div class=\"col-md-6\">\n\t\t\t\t\t\t<div class=\"card\">\n\t\t\t\t\t\t\t<div class=\"card-header\">\n\t\t\t\t\t\t\t\t<span class=\"card-title\">Local Stream\n\t\t\t\t\t\t\t\t\t<div class=\"btn-group btn-group-sm top-right hide\">\n\t\t\t\t\t\t\t\t\t\t<button class=\"btn btn-danger\" autocomplete=\"off\" id=\"toggleaudio\">Disable audio</button>\n\t\t\t\t\t\t\t\t\t\t<button class=\"btn btn-danger\" autocomplete=\"off\" id=\"togglevideo\">Disable video</button>\n\t\t\t\t\t\t\t\t\t\t<div class=\"btn-group btn-group-sm\">\n\t\t\t\t\t\t\t\t\t\t\t<button id=\"bitrateset\" autocomplete=\"off\" class=\"btn btn-primary dropdown-toggle\" data-bs-toggle=\"dropdown\">\n\t\t\t\t\t\t\t\t\t\t\t\tBandwidth\n\t\t\t\t\t\t\t\t\t\t\t</button>\n\t\t\t\t\t\t\t\t\t\t\t<ul id=\"bitrate\" class=\"dropdown-menu\" role=\"menu\">\n\t\t\t\t\t\t\t\t\t\t\t\t<a class=\"dropdown-item\" href=\"#\" id=\"0\">No limit</a>\n\t\t\t\t\t\t\t\t\t\t\t\t<a class=\"dropdown-item\" href=\"#\" id=\"128\">Cap to 128kbit</a>\n\t\t\t\t\t\t\t\t\t\t\t\t<a class=\"dropdown-item\" href=\"#\" id=\"256\">Cap to 256kbit</a>\n\t\t\t\t\t\t\t\t\t\t\t\t<a class=\"dropdown-item\" href=\"#\" id=\"512\">Cap to 512kbit</a>\n\t\t\t\t\t\t\t\t\t\t\t\t<a class=\"dropdown-item\" href=\"#\" id=\"1024\">Cap to 1mbit</a>\n\t\t\t\t\t\t\t\t\t\t\t\t<a class=\"dropdown-item\" href=\"#\" id=\"1500\">Cap to 1.5mbit</a>\n\t\t\t\t\t\t\t\t\t\t\t\t<a class=\"dropdown-item\" href=\"#\" id=\"2000\">Cap to 2mbit</a>\n\t\t\t\t\t\t\t\t\t\t\t</ul>\n\t\t\t\t\t\t\t\t\t\t</div>\n\t\t\t\t\t\t\t\t\t</div>\n\t\t\t\t\t\t\t\t</span>\n\t\t\t\t\t\t\t</div>\n\t\t\t\t\t\t\t<div class=\"card-body\" id=\"videoleft\"></div>\n\t\t\t\t\t\t</div>\n\t\t\t\t\t\t<div class=\"input-group mt-3 mb-3\">\n\t\t\t\t\t\t\t<span class=\"input-group-text\"><i class=\"fa-solid fa-cloud-arrow-up\"></i></span>\n\t\t\t\t\t\t\t<input type=\"text\" class=\"form-control\" placeholder=\"Write a DataChannel message\" autocomplete=\"off\" id=\"datasend\" onkeypress=\"return checkEnter(event);\" disabled>\n\t\t\t\t\t\t</div>\n\t\t\t\t\t</div>\n\t\t\t\t\t<div class=\"col-md-6\">\n\t\t\t\t\t\t<div class=\"card\">\n\t\t\t\t\t\t\t<div class=\"card-header\">\n\t\t\t\t\t\t\t\t<span class=\"card-title\">Remote Stream <span class=\"badge bg-primary hide\" id=\"curres\"></span> <span class=\"badge bg-info hide\" id=\"curbitrate\"></span></span>\n\t\t\t\t\t\t\t</div>\n\t\t\t\t\t\t\t<div class=\"card-body\" id=\"videoright\"></div>\n\t\t\t\t\t\t</div>\n\t\t\t\t\t\t<div class=\"input-group mt-3 mb-3\">\n\t\t\t\t\t\t\t<span class=\"input-group-text\"><i class=\"fa-solid fa-cloud-arrow-down\"></i></span>\n\t\t\t\t\t\t\t<input type=\"text\" class=\"form-control\" id=\"datarecv\" disabled>\n\t\t\t\t\t\t</div>\n\t\t\t\t\t</div>\n\t\t\t\t</div>\n\t\t\t</div>\n\t\t</div>\n\t</div>\n\n\t<hr>\n\t<div class=\"footer\">\n\t</div>\n</div>\n\n</body>\n</html>\n"

In\n\t\t\t\t\t\tfact, while the SIP plugin allows you to not worry about SIP details, which are implemented within\n\t\t\t\t\t\tthe plugin itself, the NoSIP plugin doesn't mess with signalling itself, leaving it up to the\n\t\t\t\t\t\tapplication. As such, it provided an alternative to those that still want to interact with a legacy\n\t\t\t\t\t\tinfrastructure (e.g., a pre-existing SIP-based one), but still want to be able to have control\n\t\t\t\t\t\ton the signalling themselves, rather than completely delegating it to the SIP plugin.</p>\n\t\t\t\t\t\t<p>All this plugin does, as a consequence, is taking care of the translation between WebRTC\n\t\t\t\t\t\tempowered SDPs, and barebone SDPs that can be used with legacy peers. The barebone SDPs the\n\t\t\t\t\t\tplugin generates are crafted so that media is handled by the plugin itself, thus implementing\n\t\t\t\t\t\tthe same RTP/RTCP gateway functionality the SIP plugin provides, but without the constraint\n\t\t\t\t\t\tof the signalling. It is up to the appplication to transport a generated offer in whatever\n\t\t\t\t\t\tsignalling they want to use (e.g., SIP, IAX, XMPP, etc.) and make sure the offer/answer from\n\t\t\t\t\t\tthe peer is passed to the plugin, so that the session can be completed.</p>\n\t\t\t\t\t\t<p>Considering this plugin is very much generic and signalling-agnostic, this demo does NOT\n\t\t\t\t\t\tinvolve any signalling at all. On the contrary, it will show how a WebRTC peer can establish\n\t\t\t\t\t\ta session with another WebRTC peer (for the sake of simplicity located in the same page)\n\t\t\t\t\t\tby passing through the RTP/RTCP gatewaying functionality. This should as a result make it easier\n\t\t\t\t\t\tfor you to understand how a NoSIP caller and a NoSIP callee would need to be implemented. The\n\t\t\t\t\t\tbarebone SDPs generated/processed as a consequence will be displayed as a proof of concept.</p>\n\t\t\t\t\t\t<p>Press the <code>Start</code> button above to launch the demo.</p>\n\t\t\t\t\t</div>\n\t\t\t\t</div>\n\t\t\t</div>\n\t\t\t<div class=\"container mt-4 hide\" id=\"videos\">\n\t\t\t\t<div class=\"row\">\n\t\t\t\t\t<div class=\"col-md-6\">\n\t\t\t\t\t\t<div class=\"card\">\n\t\t\t\t\t\t\t<div class=\"card-header\">\n\t\t\t\t\t\t\t\t<span class=\"card-title\">Caller\n\t\t\t\t\t\t\t\t\t<div class=\"btn-group btn-group-sm top-right\">\n\t\t\t\t\t\t\t\t\t\t<button class=\"btn btn-danger\" autocomplete=\"off\" id=\"togglevideo\" disabled>Disable video</button>\n\t\t\t\t\t\t\t\t\t</div>\n\t\t\t\t\t\t\t\t</span>\n\t\t\t\t\t\t\t</div>\n\t\t\t\t\t\t\t<div class=\"card-body\" id=\"videoleft\"></div>\n\t\t\t\t\t\t</div>\n\t\t\t\t\t\t<pre class=\"card card-body bg-gray mt-3\" id=\"localsdp\"></pre>\n\t\t\t\t\t</div>\n\t\t\t\t\t<div class=\"col-md-6\">\n\t\t\t\t\t\t<div class=\"card\">\n\t\t\t\t\t\t\t<div class=\"card-header\">\n\t\t\t\t\t\t\t\t<span class=\"card-title\">Callee</span>\n\t\t\t\t\t\t\t</div>\n\t\t\t\t\t\t\t<div class=\"card-body\" id=\"videoright\"></div>\n\t\t\t\t\t\t</div>\n\t\t\t\t\t\t<pre class=\"card card-body bg-gray mt-3\" id=\"remotesdp\"></pre>\n\t\t\t\t\t</div>\n\t\t\t\t</div>\n\t\t\t</div>\n\t\t</div>\n\t</div>\n\n\t<hr>\n\t<div class=\"footer\">\n\t</div>\n</div>\n\n</body>\n</html>\n"

This is helpful any time Janus\n// and its demos need to be deployed in a different environment, and\n// so all demos can be installed as are, by just updating the settings.js\n// file accordingly to account for the custom changes.\n//\n// We make use of this 'server' variable to provide the address of the\n// Janus API backend. By default, in this example we assume that Janus is\n// co-located with the web server hosting the HTML pages but listening\n// on a different port (8088, the default for HTTP in Janus), which is\n// why we make use of the 'window.location.hostname' base address. Since\n// Janus can also do HTTPS, and considering we don't really want to make\n// use of HTTP for Janus if your demos are served on HTTPS, we also rely\n// on the 'window.location.protocol' prefix to build the variable, in\n// particular to also change the port used to contact Janus (8088 for\n// HTTP and 8089 for HTTPS, if enabled).\n// In case you place Janus behind an Apache frontend (as we did on the\n// online demos at http://janus.conf.meetecho.com) you can just use a\n// relative path for the variable, e.g.:\n//\n// \t\tvar server = \"/janus\";\n//\n// which will take care of this on its own.\n//\n// If you want to use the WebSockets frontend to Janus, instead (which\n// is what we recommend, since they're more efficient than the long polling\n// we do with HTTP), you'll have to pass a different kind of address, e.g.:\n//\n// \t\tvar server = \"ws://\" + window.location.hostname + \":8188\";\n//\n// Of course this assumes that support for WebSockets has been built in\n// when compiling the server. Notice that the \"ws://\" prefix assumes\n// plain HTTP usage, so \"wss://\" should be used instead when using\n// WebSockets on HTTPS.//\n//\n// If you have multiple options available, and want to let the library\n// autodetect the best way to contact your server (or pool of servers),\n// you can also pass an array of servers, e.g., to provide alternative\n// means of access (e.g., try WebSockets first and, if that fails, fall\n// back to plain HTTP) or just have failover servers:\n//\n//\t\tvar server = [\n//\t\t\t\"ws://\" + window.location.hostname + \":8188\",\n//\t\t\t\"/janus\"\n//\t\t];\n//\n// This will tell the library to try connecting to each of the servers\n// in the presented order. The first working server will be used for\n// the whole session.\n//\nvar server = null;\nif(window.location.protocol === 'http:')\n\tserver = \"http://\" + window.location.hostname + \":8088/janus\";\nelse\n\tserver = \"https://\" + window.location.hostname + \":8089/janus\";\n\n// When creating a Janus object, we can also specify which STUN/TURN\n// servers we'd like to use to gather additional candidates. This is\n// done by passing an \"iceServers\" property when creating the Janus\n// object, meaning that the same set of servers will be used for all\n// PeerConnections that will be initialized within the context of the\n// new Janus session. When no iceServers object is provided, the janus.js\n// library automatically uses the free Google STUN servers, which means\n// it's equivalent to setting:\n//\n//\t\tvar iceServers = [{urls: \"stun:stun.l.google.com:19302\"}];\n//\n// Here are some examples of how an iceServers field may look like to\n// support TURN instead. Notice that, when a TURN server is configured,\n// there's no need to set a STUN one as well, since the TURN server will\n// be automatically contacted as a STUN server too, meaning it will be\n// used to gather both server reflexive and relay candidates.\n//\n//\t\tvar iceServers = [{urls: \"turn:yourturnserver.com:3478\", username: \"janususer\", credential: \"januspwd\"}]\n//\t\tvar iceServers = [{urls: \"turn:yourturnserver.com:443?transport=tcp\", username: \"janususer\", credential: \"januspwd\"}]\n//\t\tvar iceServers = [{urls: \"turns:yourturnserver.com:443?transport=tcp\", username: \"janususer\", credential: \"januspwd\"}]\n//\n// By default we leave the iceServers variable empty, which again means\n// janus.js will fallback to the Google STUN server by default:\n//\nvar iceServers = null;\n"

Specifically, it uses the\n\t\t\t\t\t\tSofia-based SIP plugin. Notice the plugin only exchange SIP messages from within the\n\t\t\t\t\t\tplugin itself: no SIP is done in JavaScript, except for references to SIP URIs.</p>\n\t\t\t\t\t\t<p>When started, the demo will allow you to insert a minimum set of information\n\t\t\t\t\t\trequired to REGISTER the web page as a SIP client at a SIP Proxy or PBX you specify.\n\t\t\t\t\t\tThis will allow you to call SIP URIs, or receive calls through the SIP Server itself.\n\t\t\t\t\t\tDuring a call, you'll also be able to interact with the PBX via DTMF tones, e.g.,\n\t\t\t\t\t\tto drive an Interactive Voice Response (IVR) menu that you're being presented with.</p>\n\t\t\t\t\t\t<div class=\"alert alert-info\"><b>Note well!</b> Please notice that, while audio support\n\t\t\t\t\t\thas been tested extensively, video

More specifically, the demo allows you to join\n\t\t\t\t\t\ta previously created and configured text room together with other\n\t\t\t\t\t\tparticipants, and send/receive public and private messages to\n\t\t\t\t\t\tindividual participants. To send messages on the chatroom, just type\n\t\t\t\t\t\tyour text and send. To send private messages to individual participants,\n\t\t\t\t\t\tclick the participant name in the list on the right and a custom dialog\n\t\t\t\t\t\twill appear.</p>\n\t\t\t\t\t\t<p>To try the demo, just insert a username to join the room. This will\n\t\t\t\t\t\tadd you to chatroom, and allow you to interact with the other participants.</p>\n\t\t\t\t\t\t<p>Notice that this is just a very basic demo, and that is just one of\n\t\t\t\t\t\tthe several different ways you can use this plugin for. The plugin\n\t\t\t\t\t\tactually allows you to join multiple rooms at the same time, and also\n\t\t\t\t\t\tto forward incoming messages to the room to external components. This\n\t\t\t\t\t\tmakes it a useful tool whenever you have to interact with third party\n\t\t\t\t\t\tapplications and exchange text data.</p>\n\t\t\t\t\t\t<p>Press the <code>Start</code> button above to launch the demo.</p>\n\t\t\t\t\t</div>\n\t\t\t\t</div>\n\t\t\t</div>\n\t\t\t<div class=\"container mt-4 hide\" id=\"roomjoin\">\n\t\t\t\t<div class=\"row\">\n\t\t\t\t\t<span class=\"badge bg-info\" id=\"you\"></span>\n\t\t\t\t\t<div class=\"col-md-12\" id=\"controls\">\n\t\t\t\t\t\t<div class=\"input-group mt-3 mb-1 hide\" id=\"registernow\">\n\t\t\t\t\t\t\t<span class=\"input-group-text\"><i class=\"fa-solid fa-user\"></i></span>\n\t\t\t\t\t\t\t<input class=\"form-control\" type=\"text\" placeholder=\"Choose a display name\" autocomplete=\"off\" id=\"username\" onkeypress=\"return checkEnter(this, event);\" />\n\t\t\t\t\t\t\t<span class=\"input-group-btn\">\n\t\t\t\t\t\t\t\t<button class=\"btn btn-success\" autocomplete=\"off\" id=\"register\">Join the room</button>\n\t\t\t\t\t\t\t</span>\n\t\t\t\t\t\t</div>\n\t\t\t\t\t</div>\n\t\t\t\t</div>\n\t\t\t</div>\n\t\t\t<div class=\"container mt-4 hide\" id=\"room\">\n\t\t\t\t<div class=\"row\">\n\t\t\t\t\t<div class=\"col-md-4\">\n\t\t\t\t\t\t<div class=\"card\">\n\t\t\t\t\t\t\t<div class=\"card-header\">\n\t\t\t\t\t\t\t\t<span class=\"card-title\">Participants <span class=\"badge bg-info hide\" id=\"participant\"></span></span>\n\t\t\t\t\t\t\t</div>\n\t\t\t\t\t\t\t<div class=\"card-body\">\n\t\t\t\t\t\t\t\t<ul id=\"list\" class=\"list-group\">\n\t\t\t\t\t\t\t\t</ul>\n\t\t\t\t\t\t\t</div>\n\t\t\t\t\t\t</div>\n\t\t\t\t\t</div>\n\t\t\t\t\t<div class=\"col-md-8\">\n\t\t\t\t\t\t<div class=\"card\">\n\t\t\t\t\t\t\t<div class=\"card-header\">\n\t\t\t\t\t\t\t\t<span class=\"card-title\">Public Chatroom</span>\n\t\t\t\t\t\t\t</div>\n\t\t\t\t\t\t\t<div class=\"card-body relative\" style=\"overflow-x: auto;\" id=\"chatroom\">\n\t\t\t\t\t\t\t</div>\n\t\t\t\t\t\t\t<div class=\"card-footer\">\n\t\t\t\t\t\t\t\t<div class=\"input-group mt-3 mb-3\">\n\t\t\t\t\t\t\t\t\t<span class=\"input-group-text\"><i class=\"fa-solid fa-cloud-arrow-up\"></i></span>\n\t\t\t\t\t\t\t\t\t<input class=\"form-control\" type=\"text\" placeholder=\"Write a chatroom message\" autocomplete=\"off\" id=\"datasend\" onkeypress=\"return checkEnter(this, event);\" disabled />\n\t\t\t\t\t\t\t\t</div>\n\t\t\t\t\t\t\t</div>\n\t\t\t\t\t\t</div>\n\t\t\t\t\t</div>\n\t\t\t\t</div>\n\t\t\t</div>\n\t\t</div>\n\t</div>\n\n\t<hr>\n\t<div class=\"footer\">\n\t</div>\n</div>\n\n</body>\n</html>\n"

It\n\t\t\t\t\t\tbasically is an extension to the Echo Test demo, where in this case the media\n\t\t\t\t\t\tpackets and statistics are forwarded between the two involved peers.</p>\n\t\t\t\t\t\t<p>Using the demo is simple. Just choose a simple username to register\n\t\t\t\t\t\tat the plugin, and then either call another user (provided you know\n\t\t\t\t\t\twhich username was picked) or share your username with a friend and\n\t\t\t\t\t\twait for a call. At that point, you'll be in a video call with the\n\t\t\t\t\t\tremote peer, and you'll have the same controls the Echo Test demo\n\t\t\t\t\t\tprovides to try and control the media: that is, a button to mute/unmute\n\t\t\t\t\t\tyour audio and video, and a knob to try and limit your bandwidth. If\n\t\t\t\t\t\tthe browser supports it, you'll also get a view of the bandwidth\n\t\t\t\t\t\tcurrently used by your peer for the video stream.</p>\n\t\t\t\t\t\t<p>If you're interested in testing how simulcasting can be used within\n\t\t\t\t\t\tthe context of this sample videocall application, just pass the\n\t\t\t\t\t\t<code>?simulcast=true</code> query string to the url of this page and\n\t\t\t\t\t\treload it. If you're using a browser that does support simulcasting\n\t\t\t\t\t\t(Chrome or Firefox) and the call will end up using VP8, you'll\n\t\t\t\t\t\tsend multiple qualities of the video you're capturing. Notice that\n\t\t\t\t\t\tsimulcasting will only occur if the browser thinks there is enough\n\t\t\t\t\t\tbandwidth, so you'll have to play with the Bandwidth selector to\n\t\t\t\t\t\tincrease it. New buttons to play with the feature will automatically\n\t\t\t\t\t\tappear for your peer; at the same time, if your peer enabled simulcasting\n\t\t\t\t\t\tnew buttons will appear for you when watching the remote stream. Notice that\n\t\t\t\t\t\tno simulcast support is needed for watching, only for publishing.</p>\n\t\t\t\t\t\t<p>A very simple chat based on Data Channels is available as well:\n\t\t\t\t\t\tjust use the text area under your local video to send messages\n\t\t\t\t\t\tto your peer. Incoming messages will be displayed below the\n\t\t\t\t\t\tremote video instead.</p>\n\t\t\t\t\t\t<p>Press the <code>Start</code> button above to launch the demo.</p>\n\t\t\t\t\t</div>\n\t\t\t\t</div>\n\t\t\t</div>\n\t\t\t<div class=\"container hide\" id=\"videocall\">\n\t\t\t\t<div class=\"row mt-4\">\n\t\t\t\t\t<div class=\"col-md-6 container invisible\" id=\"login\">\n\t\t\t\t\t\t<div class=\"input-group mt-3 mb-1\">\n\t\t\t\t\t\t\t<span class=\"input-group-text\"><i class=\"fa-solid fa-user\"></i></span>\n\t\t\t\t\t\t\t<input class=\"form-control\" type=\"text\" placeholder=\"Choose a username\" autocomplete=\"off\" id=\"username\" onkeypress=\"return checkEnter(this, event);\" />\n\t\t\t\t\t\t</div>\n\t\t\t\t\t\t<button class=\"btn btn-success mb-1\" autocomplete=\"off\" id=\"register\">Register</button> <span class=\"hide badge bg-info\" id=\"youok\"></span>\n\t\t\t\t\t</div>\n\t\t\t\t\t<div class=\"col-md-6 container invisible\" id=\"phone\">\n\t\t\t\t\t\t<div class=\"input-group mt-3 mb-1\">\n\t\t\t\t\t\t\t<span class=\"input-group-text\"><i class=\"fa-solid fa-phone\"></i></span>\n\t\t\t\t\t\t\t<input class=\"form-control\" type=\"text\" placeholder=\"Who should we call?\" autocomplete=\"off\" id=\"peer\" onkeypress=\"return checkEnter(this, event);\" />\n\t\t\t\t\t\t</div>\n\t\t\t\t\t\t<button class=\"btn btn-success mb-1\" autocomplete=\"off\" id=\"call\">Call</button>\n\t\t\t\t\t</div>\n\t\t\t\t</div>\n\t\t\t\t<div id=\"videos\" class=\"row mt-4 hide\">\n\t\t\t\t\t<div class=\"col-md-6\">\n\t\t\t\t\t\t<div class=\"card\">\n\t\t\t\t\t\t\t<div class=\"card-header\">\n\t\t\t\t\t\t\t\t<span class=\"card-title\">Local Stream\n\t\t\t\t\t\t\t\t\t<div class=\"btn-group btn-group-sm top-right hide\">\n\t\t\t\t\t\t\t\t\t\t<button class=\"btn btn-danger\" autocomplete=\"off\" id=\"toggleaudio\">Disable audio</button>\n\t\t\t\t\t\t\t\t\t\t<button class=\"btn btn-danger\" autocomplete=\"off\" id=\"togglevideo\">Disable video</button>\n\t\t\t\t\t\t\t\t\t\t<div class=\"btn-group btn-group-sm\">\n\t\t\t\t\t\t\t\t\t\t\t<button autocomplete=\"off\" id=\"bitrateset\" class=\"btn btn-primary dropdown-toggle\" data-bs-toggle=\"dropdown\">\n\t\t\t\t\t\t\t\t\t\t\t\tBandwidth\n\t\t\t\t\t\t\t\t\t\t\t</button>\n\t\t\t\t\t\t\t\t\t\t\t<ul id=\"bitrate\" class=\"dropdown-menu\" role=\"menu\">\n\t\t\t\t\t\t\t\t\t\t\t\t<a class=\"dropdown-item\" href=\"#\" id=\"0\">No limit</a>\n\t\t\t\t\t\t\t\t\t\t\t\t<a class=\"dropdown-item\" href=\"#\" id=\"128\">Cap to 128kbit</a>\n\t\t\t\t\t\t\t\t\t\t\t\t<a class=\"dropdown-item\" href=\"#\" id=\"256\">Cap to 256kbit</a>\n\t\t\t\t\t\t\t\t\t\t\t\t<a class=\"dropdown-item\" href=\"#\" id=\"512\">Cap to 512kbit</a>\n\t\t\t\t\t\t\t\t\t\t\t\t<a class=\"dropdown-item\" href=\"#\" id=\"1024\">Cap to 1mbit</a>\n\t\t\t\t\t\t\t\t\t\t\t\t<a class=\"dropdown-item\" href=\"#\" id=\"1500\">Cap to 1.5mbit</a>\n\t\t\t\t\t\t\t\t\t\t\t\t<a class=\"dropdown-item\" href=\"#\" id=\"2000\">Cap to 2mbit</a>\n\t\t\t\t\t\t\t\t\t\t\t</ul>\n\t\t\t\t\t\t\t\t\t\t</div>\n\t\t\t\t\t\t\t\t\t</div>\n\t\t\t\t\t\t\t\t</span>\n\t\t\t\t\t\t\t</div>\n\t\t\t\t\t\t\t<div class=\"card-body\" id=\"videoleft\"></div>\n\t\t\t\t\t\t</div>\n\t\t\t\t\t\t<div class=\"input-group mt-3 mb-3\">\n\t\t\t\t\t\t\t<span class=\"input-group-text\"><i class=\"fa-solid fa-cloud-arrow-up\"></i></span>\n\t\t\t\t\t\t\t<input type=\"text\" class=\"form-control\" placeholder=\"Write a DataChannel message\" autocomplete=\"off\" id=\"datasend\" onkeypress=\"return checkEnter(this, event);\" disabled>\n\t\t\t\t\t\t</div>\n\t\t\t\t\t</div>\n\t\t\t\t\t<div class=\"col-md-6\">\n\t\t\t\t\t\t<div class=\"card\">\n\t\t\t\t\t\t\t<div class=\"card-header\">\n\t\t\t\t\t\t\t\t<span class=\"card-title\">Remote Stream\n\t\t\t\t\t\t\t\t\t<span class=\"badge bg-info hide\" id=\"callee\"></span>\n\t\t\t\t\t\t\t\t\t<span class=\"badge bg-primary hide\" id=\"curres\"></span>\n\t\t\t\t\t\t\t\t\t<span class=\"badge bg-info hide\" id=\"curbitrate\"></span>\n\t\t\t\t\t\t\t\t</span>\n\t\t\t\t\t\t\t</div>\n\t\t\t\t\t\t\t<div class=\"card-body\" id=\"videoright\"></div>\n\t\t\t\t\t\t</div>\n\t\t\t\t\t\t<div class=\"input-group mt-3 mb-3\">\n\t\t\t\t\t\t\t<span class=\"input-group-text\"><i class=\"fa-solid fa-cloud-arrow-down\"></i></span>\n\t\t\t\t\t\t\t<input type=\"text\" class=\"form-control\" id=\"datarecv\" disabled>\n\t\t\t\t\t\t</div>\n\t\t\t\t\t</div>\n\t\t\t\t</div>\n\t\t\t</div>\n\t\t</div>\n\t</div>\n\n\t<hr>\n\t<div class=\"footer\">\n\t</div>\n</div>\n\n</body>\n</html>\n"

In particular, this\n\t\t\t\t\t\tdemo page allows you to have up to 6 active participants at the same time:\n\t\t\t\t\t\tmore participants joining the room will be instead just passive users.\n\t\t\t\t\t\tNo mixing is involved: all media are just relayed in a publisher/subscriber\n\t\t\t\t\t\tapproach. This means that the plugin acts as a SFU (Selective Forwarding Unit)\n\t\t\t\t\t\trather than an MCU (Multipoint Control Unit).</p>\n\t\t\t\t\t\t<div class=\"alert alert-info\">Notice that this is the <b>original</b> VideoRoom\n\t\t\t\t\t\tdemo, and uses a different PeerConnections per each subscription: if\n\t\t\t\t\t\tyou want to test the new multistream support, instead, try the\n\t\t\t\t\t\t<a href=\"mvideoroom.html\">multistream VideoRoom demo</a>\n\t\t\t\t\t\tinstead. The two demos are interoperable, if you want to see how\n\t\t\t\t\t\tdifferent subscription mechanisms are used on the same sources.</div>\n\t\t\t\t\t\t<p>If you're interested in testing how simulcasting or SVC can be used within\n\t\t\t\t\t\tthe context of a videoconferencing application, just pass a\n\t\t\t\t\t\t<code>?simulcast=true</code> (for simulcast) or <code>?svc=&lt;mode&gt;</code>\n\t\t\t\t\t\t(for SVC) query string to the url of this page and reload it. Notice that\n\t\t\t\t\t\tsimulcast will only work when using VP8 or H.264 (or, if you're using a\n\t\t\t\t\t\trecent version of Chrome, VP9 and AV1 too), while SVC will only work\n\t\t\t\t\t\tif you're using VP9 or AV1 on a browser that supports setting the <code>scalabilityMode</code>.\n\t\t\t\t\t\tBesides, notice that simulcasting/SVC will only be sent if the browser thinks\n\t\t\t\t\t\tthere is enough bandwidth, so you may have to play with the Bandwidth selector to\n\t\t\t\t\t\tincrease it. New buttons to play with the feature will automatically\n\t\t\t\t\t\tappear for viewers when receiving any simulcast/SVC stream. Notice that\n\t\t\t\t\t\tno simulcast/SVC support is needed for watching, only for publishing.</p>\n\t\t\t\t\t\t<p>To use the demo, just insert a username to join the default room that\n\t\t\t\t\t\tis configured. This will add you to the list of participants, and allow\n\t\t\t\t\t\tyou to automatically send your audio/video frames and receive the other\n\t\t\t\t\t\tparticipants' feeds. The other participants will appear in separate\n\t\t\t\t\t\tpanels, whose title will be the names they chose when registering at\n\t\t\t\t\t\tthe demo.</p>\n\t\t\t\t\t\t<p>Press the <code>Start</code> button above to launch the demo.</p>\n\t\t\t\t\t</div>\n\t\t\t\t</div>\n\t\t\t</div>\n\t\t\t<div class=\"container mt-4 hide\" id=\"videojoin\">\n\t\t\t\t<div class=\"row\">\n\t\t\t\t\t<span class=\"badge bg-info\" id=\"you\"></span>\n\t\t\t\t\t<div class=\"col-md-12\" id=\"controls\">\n\t\t\t\t\t\t<div class=\"input-group mt-3 mb-1 hide\" id=\"registernow\">\n\t\t\t\t\t\t\t<span class=\"input-group-text\"><i class=\"fa-solid fa-user\"></i></span>\n\t\t\t\t\t\t\t<input autocomplete=\"off\" class=\"form-control\" type=\"text\" placeholder=\"Choose a display name\" id=\"username\" onkeypress=\"return checkEnter(this, event);\" />\n\t\t\t\t\t\t\t<span class=\"input-group-btn\">\n\t\t\t\t\t\t\t\t<button class=\"btn btn-success\" autocomplete=\"off\" id=\"register\">Join the room</button>\n\t\t\t\t\t\t\t</span>\n\t\t\t\t\t\t</div>\n\t\t\t\t\t</div>\n\t\t\t\t</div>\n\t\t\t</div>\n\t\t\t<div class=\"container mt-4 hide\" id=\"videos\">\n\t\t\t\t<div class=\"row\">\n\t\t\t\t\t<div class=\"col-md-4\">\n\t\t\t\t\t\t<div class=\"card\">\n\t\t\t\t\t\t\t<div class=\"card-header\">\n\t\t\t\t\t\t\t\t<span class=\"card-title\">Local Video <span class=\"badge bg-primary hide\" id=\"publisher\"></span>\n\t\t\t\t\t\t\t\t\t<div class=\"btn-group btn-group-sm top-right hide\">\n\t\t\t\t\t\t\t\t\t\t<div class=\"btn-group btn-group-sm\">\n\t\t\t\t\t\t\t\t\t\t\t<button id=\"bitrateset\" autocomplete=\"off\" class=\"btn btn-primary dropdown-toggle\" data-bs-toggle=\"dropdown\">\n\t\t\t\t\t\t\t\t\t\t\t\tBandwidth\n\t\t\t\t\t\t\t\t\t\t\t</button>\n\t\t\t\t\t\t\t\t\t\t\t<ul id=\"bitrate\" class=\"dropdown-menu\" role=\"menu\">\n\t\t\t\t\t\t\t\t\t\t\t\t<a class=\"dropdown-item\" href=\"#\" id=\"0\">No limit</a>\n\t\t\t\t\t\t\t\t\t\t\t\t<a class=\"dropdown-item\" href=\"#\" id=\"128\">Cap to 128kbit</a>\n\t\t\t\t\t\t\t\t\t\t\t\t<a class=\"dropdown-item\" href=\"#\" id=\"256\">Cap to 256kbit</a>\n\t\t\t\t\t\t\t\t\t\t\t\t<a class=\"dropdown-item\" href=\"#\" id=\"512\">Cap to 512kbit</a>\n\t\t\t\t\t\t\t\t\t\t\t\t<a class=\"dropdown-item\" href=\"#\" id=\"1024\">Cap to 1mbit</a>\n\t\t\t\t\t\t\t\t\t\t\t\t<a class=\"dropdown-item\" href=\"#\" id=\"1500\">Cap to 1.5mbit</a>\n\t\t\t\t\t\t\t\t\t\t\t\t<a class=\"dropdown-item\" href=\"#\" id=\"2000\">Cap to 2mbit</a>\n\t\t\t\t\t\t\t\t\t\t\t</ul>\n\t\t\t\t\t\t\t\t\t\t</div>\n\t\t\t\t\t\t\t\t\t</div>\n\t\t\t\t\t\t\t\t</span>\n\t\t\t\t\t\t\t</div>\n\t\t\t\t\t\t\t<div class=\"card-body\" id=\"videolocal\"></div>\n\t\t\t\t\t\t</div>\n\t\t\t\t\t</div>\n\t\t\t\t\t<div class=\"col-md-4\">\n\t\t\t\t\t\t<div class=\"card\">\n\t\t\t\t\t\t\t<div class=\"card-header\">\n\t\t\t\t\t\t\t\t<span class=\"card-title\">Remote Video #1 <span class=\"badge bg-info hide\" id=\"remote1\"></span></span>\n\t\t\t\t\t\t\t</div>\n\t\t\t\t\t\t\t<div class=\"card-body relative\" id=\"videoremote1\"></div>\n\t\t\t\t\t\t</div>\n\t\t\t\t\t</div>\n\t\t\t\t\t<div class=\"col-md-4\">\n\t\t\t\t\t\t<div class=\"card\">\n\t\t\t\t\t\t\t<div class=\"card-header\">\n\t\t\t\t\t\t\t\t<span class=\"card-title\">Remote Video #2 <span class=\"badge bg-info hide\" id=\"remote2\"></span></span>\n\t\t\t\t\t\t\t</div>\n\t\t\t\t\t\t\t<div class=\"card-body relative\" id=\"videoremote2\"></div>\n\t\t\t\t\t\t</div>\n\t\t\t\t\t</div>\n\t\t\t\t</div>\n\t\t\t\t<div class=\"row\">\n\t\t\t\t\t<div class=\"col-md-4\">\n\t\t\t\t\t\t<div class=\"card\">\n\t\t\t\t\t\t\t<div class=\"card-header\">\n\t\t\t\t\t\t\t\t<span class=\"card-title\">Remote Video #3 <span class=\"badge bg-info hide\" id=\"remote3\"></span></span>\n\t\t\t\t\t\t\t</div>\n\t\t\t\t\t\t\t<div class=\"card-body relative\" id=\"videoremote3\"></div>\n\t\t\t\t\t\t</div>\n\t\t\t\t\t</div>\n\t\t\t\t\t<div class=\"col-md-4\">\n\t\t\t\t\t\t<div class=\"card\">\n\t\t\t\t\t\t\t<div class=\"card-header\">\n\t\t\t\t\t\t\t\t<span class=\"card-title\">Remote Video #4 <span class=\"badge bg-info hide\" id=\"remote4\"></span></span>\n\t\t\t\t\t\t\t</div>\n\t\t\t\t\t\t\t<div class=\"card-body relative\" id=\"videoremote4\"></div>\n\t\t\t\t\t\t</div>\n\t\t\t\t\t</div>\n\t\t\t\t\t<div class=\"col-md-4\">\n\t\t\t\t\t\t<div class=\"card\">\n\t\t\t\t\t\t\t<div class=\"card-header\">\n\t\t\t\t\t\t\t\t<span class=\"card-title\">Remote Video #5 <span class=\"badge bg-info hide\" id=\"remote5\"></span></span>\n\t\t\t\t\t\t\t</div>\n\t\t\t\t\t\t\t<div class=\"card-body relative\" id=\"videoremote5\"></div>\n\t\t\t\t\t\t</div>\n\t\t\t\t\t</div>\n\t\t\t\t</div>\n\t\t\t</div>\n\t\t</div>\n\t</div>\n\n\t<hr>\n\t<div class=\"footer\">\n\t</div>\n</div>\n\n</body>\n</html>\n"

This is the only authorized version of `janus.js` on npm:\n\nhttps://www.npmjs.com/package/janus-gateway\n\nIf you encounter other versions, they were not made nor uploaded by [Meetecho](https://www.meetecho.com), and so should be considered not trusted.\n\nFor information on how to use the library, please refer to the [official documentation](https://janus.conf.meetecho.com/docs/JS), which includes information on how to use `janus.js` as a module.\n\n> **Note well**: please notice that `janus.js` is mostly meant as a convenience library for use in our Janus demos, and is not necessarily suited for production usages. For a more modern JavaScript and Node.js SDK to use with Janus, please refer to [Janode](https://www.npmjs.com/package/janode) instead.\n"

What\n * to do with these events is then up to the handler: it may choose to store\n * them somewhere (e.g., a database), analyse and process them, or simply\n * send them to an external tool for statistics purposes or troubleshooting.\n * Whatever the aim, the structures to make the interaction between core\n * and event handlers possible are defined here.\n *\n * An event handler plugin that wants to register at the Janus core needs to\n * implement the \\c janus_eventhandler interface. This includes callbacks\n * the Janus core can use to pass and request information, and a mask of\n * the events the plugin is interested in subscribing to. Besides, as an\n * event handler plugin is a shared object, and as such external to the\n * core itself, in order to be dynamically loaded at startup it needs\n * to implement the \\c create_e() hook as well, that should return a\n * pointer to the plugin instance. This is an example of such a step:\n *\n\\verbatim\nstatic janus_eventhandler myhandler = {\n\t[..]\n};\n\njanus_eventhandler *create(void) {\n\tJANUS_LOG(LOG_VERB, , \"%s created!\\n\", MY_HANDLER_NAME);\n\treturn &myhandler;\n}\n\\endverbatim\n *\n * This will make sure that your event handler plugin is loaded at startup\n * by the Janus core, if it is deployed in the proper folder.\n *\n * As anticipated and described in the above example, an event handler plugin\n * must basically be an instance of the \\c janus_eventhandler type. As such,\n * it must implement the following methods and callbacks for the core:\n *\n * - \\c init(): this is called by the Janus core as soon as your event handler\n * plugin is started; this is where you should setup your event handler plugin\n * (e.g., static stuff and reading the configuration file);\n * - \\c destroy(): on the other hand, this is called by the core when it\n * is shutting down, and your event handler plugin should too;\n * - \\c get_api_compatibility(): this method MUST return JANUS_EVENTHANDLER_API_VERSION;\n * - \\c get_version(): this method should return a numeric version identifier (e.g., 3);\n * - \\c get_version_string(): this method should return a verbose version identifier (e.g., \"v1.0.1\");\n * - \\c get_description(): this method should return a verbose description of your event handler plugin (e.g., \"This is an event handler that saves some events on a database\");\n * - \\c get_name(): this method should return a short display name for your event handler plugin (e.g., \"My Amazing Event Handler\");\n * - \\c get_package(): this method should return a unique package identifier for your event handler plugin (e.g., \"janus.eventhandler.myeventhandler\");\n * - \\c incoming_event(): this callback informs the event handler that an event is available for consumption.\n *\n * All the above methods and callbacks are mandatory: the Janus core will\n * reject an event handler plugin that doesn't implement any of the\n * mandatory callbacks.\n *\n * Additionally, a \\c janus_eventhandler instance must also include a\n * mask of the events it is interested in, a \\c events_mask janus_flag\n * object that must refer to the available types defined in this header.\n * The core, in fact, will refer to that mask to check whether your event\n * handler is interested in a specific event or not.\n *\n * Unlike other kind of modules (transports, plugins), the \\c init() method\n * here only passes the path to the configurations files folder, as event\n * handlers never need to contact the Janus core themselves. This path can be used to read and\n * parse a configuration file for the event handler plugin: the event handler\n * plugins we made available out of the box use the package name as a\n * name for the file (e.g., \\c janus.eventhandler.fake.jcfg for the sample\n * event handler plugin), but you're free to use a different one, as long\n * as it doesn't collide with existing ones. Besides, the existing eventhandler\n * plugins use the same libconfig format for configuration files the core\n * uses (relying on the \\c janus_config helpers for the purpose) but\n * again, if you prefer a different format (XML, JSON, etc.) that's up to you.\n *\n * \\ingroup eventhandlerapi\n * \\ref eventhandlerapi\n */\n\n#ifndef JANUS_EVENTHANDLER_H\n#define JANUS_EVENTHANDLER_H\n\n#include <stdlib.h>\n#include <stdint.h>\n#include <stdio.h>\n#include <string.h>\n#include <ctype.h>\n#include <unistd.h>\n#include <inttypes.h>\n\n#include <glib.h>\n#include <jansson.h>\n\n#include \"../utils.h\"\n\n\n/*! \\brief Version of the API, to match the one event handler plugins were compiled against */\n#define JANUS_EVENTHANDLER_API_VERSION\t3\n\n/*! \\brief Initialization of all event handler plugin properties to NULL\n *\n * \\note All event handler plugins MUST add this as the FIRST line when initializing\n * their event handler plugin structure, e.g.:\n *\n\\verbatim\nstatic janus_eventhandler janus_fake_eventhandler_plugin =\n\t{\n\t\tJANUS_EVENTHANDLER_INIT,\n\n\t\t.init = janus_fake_init,\n\t\t[..]\n\\endverbatim\n */\n\n/** @name Type of events Janus could notify, and the handler subscribe to\n * @details This mask makes it easy to subscribe to, and unsubscribe from,\n * specific events, as all you need to do is to use janus_flags_set and\n * janus_flags_clear on the \\c events_mask property of the handler instance,\n * and the core will know whether you care about something or not.\n */\n///@{\n/*! \\brief No event */\n#define JANUS_EVENT_TYPE_NONE\t\t\t(0)\n/*! \\brief Session related events (e.g., session created/destroyed, etc.) */\n#define JANUS_EVENT_TYPE_SESSION\t\t(1 << 0)\n/*! \\brief Handle related events (e.g., handle attached/detached, etc.) */\n#define JANUS_EVENT_TYPE_HANDLE\t\t\t(1 << 1)\n/*! \\brief External events originated via Admin API (e.g., custom events coming from external scripts) */\n#define JANUS_EVENT_TYPE_EXTERNAL\t\t(1 << 2)\n/*! \\brief JSEP related events (e.g., got/sent offer/answer) */\n#define JANUS_EVENT_TYPE_JSEP\t\t\t(1 << 3)\n/*! \\brief WebRTC related events (e.g., PeerConnection up/down, ICE updates, DTLS updates, etc.) */\n#define JANUS_EVENT_TYPE_WEBRTC\t\t\t(1 << 4)\n/*! \\brief Media related events (e.g., media started/stopped flowing, stats on packets/bytes, etc.) */\n#define JANUS_EVENT_TYPE_MEDIA\t\t\t(1 << 5)\n/*! \\brief Events originated by plugins (at the moment, all of them, no way to pick) */\n#define JANUS_EVENT_TYPE_PLUGIN\t\t\t(1 << 6)\n/*! \\brief Events originated by transports (at the moment, all of them, no way to pick) */\n#define JANUS_EVENT_TYPE_TRANSPORT\t\t(1 << 7)\n/*! \\brief Events originated by the core for its own events (e.g., Janus starting/shutting down) */\n#define JANUS_EVENT_TYPE_CORE\t\t\t(1 << 8)\n\t/* TODO Others? */\n/*! \\brief Mask with all events enabled (shortcut when you want to subscribe to everything) */\n#define JANUS_EVENT_TYPE_ALL\t\t(0xffffffff)\n///@}\n\n/** @name Subtype of event types Janus could notify\n * @details Some events, like JANUS_EVENT_TYPE_WEBRTC, don't have a uniform syntax:\n * an event related to a new local candidate looks very different from an event\n * related to, e.g., a selected pair or a DTLS state, all of which belong to the\n * same category of \\c webrtc type events.

There is also UDP support, but you need to limit the payload\n * size with max_message_len and remember to leave room for 12 bytes for special\n * headers. UDP messages will be chunked automatically.\n * There is also compression available for UDP protocol, to save network bandwidth\n * while using a bit more CPU. This is not available for TCP due to GELF limitations\n *\n * \\ingroup eventhandlers\n * \\ref eventhandlers\n */\n\n#include \"eventhandler.h\"\n\n#include <math.h>\n\n#include \"../debug.h\"\n#include \"../config.h\"\n#include \"../mutex.h\"\n#include \"../utils.h\"\n#include \"../events.h\"\n#include <netdb.h>\n#include <errno.h>\n#include <arpa/inet.h>\n#include <sys/socket.h>\n#include <netinet/in.h>\n#include \"../ip-utils.h\"\n\n/* Plugin information */\n#define JANUS_GELFEVH_VERSION\t\t\t1\n#define JANUS_GELFEVH_VERSION_STRING \t\"0.0.1\"\n#define JANUS_GELFEVH_DESCRIPTION \t\t\"This is event handler plugin for Janus, which forwards events via TCP/UDP to GELF server.\"\n#define JANUS_GELFEVH_NAME \t\t\t\t\"JANUS GelfEventHandler plugin\"\n#define JANUS_GELFEVH_AUTHOR \t\t\t\"Mirko Brankovic <mirkobrankovic@gmail.com>\"\n#define JANUS_GELFEVH_PACKAGE\t\t\t\"janus.eventhandler.gelfevh\"\n\n#define MAX_GELF_CHUNKS \t\t\t\t128\n\n/* Plugin methods */\njanus_eventhandler *create(void);\nint janus_gelfevh_init(const char *config_path);\nvoid janus_gelfevh_destroy(void);\nint janus_gelfevh_get_api_compatibility(void);\nint janus_gelfevh_get_version(void);\nconst char *janus_gelfevh_get_version_string(void);\nconst char *janus_gelfevh_get_description(void);\nconst char *janus_gelfevh_get_name(void);\nconst char *janus_gelfevh_get_author(void);\nconst char *janus_gelfevh_get_package(void);\nvoid janus_gelfevh_incoming_event(json_t *event);\njson_t *janus_gelfevh_handle_request(json_t *request);\n\n/* Event handler setup */\nstatic janus_eventhandler janus_gelfevh =\n\tJANUS_EVENTHANDLER_INIT (\n\t\t.init = janus_gelfevh_init,\n\t\t.destroy = janus_gelfevh_destroy,\n\n\t\t.get_api_compatibility = janus_gelfevh_get_api_compatibility,\n\t\t.get_version = janus_gelfevh_get_version,\n\t\t.get_version_string = janus_gelfevh_get_version_string,\n\t\t.get_description = janus_gelfevh_get_description,\n\t\t.get_name = janus_gelfevh_get_name,\n\t\t.get_author = janus_gelfevh_get_author,\n\t\t.get_package = janus_gelfevh_get_package,\n\n\t\t.incoming_event = janus_gelfevh_incoming_event,\n\t\t.handle_request = janus_gelfevh_handle_request,\n\n\t\t.events_mask = JANUS_EVENT_TYPE_NONE\n\t);\n\n/* Plugin creator */\njanus_eventhandler *create(void) {\n\tJANUS_LOG(LOG_VERB, \"%s created!\\n\", JANUS_GELFEVH_NAME);\n\treturn &janus_gelfevh;\n}\n\n/* Compression, if any */\nstatic gboolean compress = FALSE;\nstatic int compression = 6;

Recently, support for the libconfig format\n * has been added too. Due to the more expressive nature of libconfig, .jcfg\n * files have been made the default: while support for .cfg files still\n * exists as a fallback, new features may only be available in .jcfg files.\n * As such, you may want to convert your existing .cfg configuration files\n * to .jcfg as soon as possible, which is what this tool allows you to do.\n * Notice that the tool also allows you to go the other way around, although\n * libconfig concepts that cannot be expressed in INI will be lost in the process.\n *\n * Using the utility is quite simple. Just pass, as arguments to the tool,\n * the path to the file you want to convert (.cfg or .jcfg) and the path to\n * the target file (.jcfg or .cfg), e.g.:\n *\n\\verbatim\n./janus-cfgconv /path/to/config.cfg /path/to/config.jcfg\n\\endverbatim\n *\n * \\ingroup tools\n * \\ref tools\n */\n\n#include <stdlib.h>\n#include <string.h>\n\n#include \"config.h\"\n#include \"debug.h\"\n#include \"version.h\"\n\nint janus_log_level = 4;\ngboolean janus_log_timestamps = FALSE;\ngboolean janus_log_colors = TRUE;\nchar *janus_log_global_prefix = NULL;\nint lock_debug = 0;\n\n/* Main Code */\nint main(int argc, char *argv[])\n{\n\tjanus_log_init(FALSE, TRUE, NULL, NULL);\n\tatexit(janus_log_destroy);\n\n\tJANUS_LOG(LOG_INFO, \"Janus version: %d (%s)\\n\", janus_version, janus_version_string);\n\tJANUS_LOG(LOG_INFO, \"Janus commit: %s\\n\", janus_build_git_sha);\n\tJANUS_LOG(LOG_INFO, \"Compiled on:  %s\\n\\n\", janus_build_git_time);\n\n\t/* Evaluate arguments */\n\tif(argc != 3) {\n\t\tJANUS_LOG(LOG_INFO, \"Usage: %s source.[cfg|jcfg] destination.[cfg|jcfg]\\n\", argv[0]);\n\t\tJANUS_LOG(LOG_INFO, \"       %s --parse source.[cfg|jcfg]\\n\", argv[0]);\n\t\texit(1);\n\t}\n\tchar *source = NULL, *destination = NULL;\n\t/* Parse or convert the configuration files */\n\tgboolean only_parse = FALSE;\n\tsource = argv[1];\n\tif(!strcmp(source, \"--parse\")) {\n\t\tonly_parse = TRUE;\n\t} else {\n\t\tif(!strstr(source, \".cfg\") && !strstr(source, \".jcfg\")) {\n\t\t\tJANUS_LOG(LOG_ERR, \"Unsupported file: %s\\n\", source);\n\t\t\texit(1);\n\t\t}\n\t}\n\tdestination = argv[2];\n\tif(!strstr(destination, \".cfg\") && !strstr(destination, \".jcfg\")) {\n\t\tJANUS_LOG(LOG_ERR, \"Unsupported file: %s\\n\", destination);\n\t\texit(1);\n\t}\n\tif(only_parse) {\n\t\tsource = destination;\n\t\tdestination = NULL;\n\t\tJANUS_LOG(LOG_INFO, \"Parsing:\\n\");\n\t\tJANUS_LOG(LOG_INFO, \"   -- IN:  %s\\n\", source);\n\t} else {\n\t\tJANUS_LOG(LOG_INFO, \"Converting:\\n\");\n\t\tJANUS_LOG(LOG_INFO, \"   -- IN:  %s\\n\", source);\n\t\tJANUS_LOG(LOG_INFO, \"   -- OUT: %s\\n\\n\", destination);\n\t}\n\t/* Open the source */\n\tjanus_config *config = janus_config_parse(source);\n\tif(config == NULL)\n\t\texit(1);\n\tjanus_config_print_as(config, LOG_INFO);\n\tJANUS_LOG(LOG_INFO, \"\\n\");\n\tif(only_parse) {\n\t\t/* We're done */\n\t\tjanus_config_destroy(config);\n\t\tJANUS_LOG(LOG_INFO, \"Bye!\\n\");\n\t\treturn 0;\n\t}\n\t/* If the source is an INI, check if there are numeric categories or attribute names */\n\tif(!config->is_jcfg) {\n\t\tGList *list = config->list;\n\t\twhile(list) {\n\t\t\tjanus_config_container *c = (janus_config_container *)list->data;\n\t\t\tif(c && c->type == janus_config_type_category && c->name && atol(c->name) > 0) {\n\t\t\t\t/* FIXME Ugly hack to add the \"room-\" prefix to category names\n\t\t\t\t * (currently only needed in VideoRoom/AudioBridge/TextRoom) */\n\t\t\t\tchar newname[50];\n\t\t\t\tg_snprintf(newname, sizeof(newname), \"room-%s\", c->name);\n\t\t\t\tg_free((char *)c->name);\n\t\t\t\tc->name = g_strdup(newname);\n\t\t\t}\n\t\t\tlist = list->next;\n\t\t}\n\t}\n\t/* Is the target an INI or a libconfig file? */\n\tconfig->is_jcfg = strstr(destination, \".jcfg\") != NULL;\n\t/* Remove extension: janus_config_save adds it for us */\n\tchar *target = g_strdup(destination);\n\tchar *extension = config->is_jcfg ? strstr(target, \".jcfg\") : strstr(target, \".cfg\");\n\t*extension = '\\0';\n\t/* Save to destination */\n\tif(janus_config_save(config, NULL, target) < 0) {\n\t\tg_free(target);\n\t\tjanus_config_destroy(config);\n\t\tJANUS_LOG(LOG_ERR, \"Error saving converted file\\n\");\n\t\texit(1);\n\t}\n\tjanus_config_destroy(config);\n\t/* Make sure everything's fine */\n\tconfig = janus_config_parse(destination);\n\tif(config == NULL) {\n\t\tg_free(target);\n\t\tJANUS_LOG(LOG_ERR, \"Error parsing converted file\\n\");\n\t\texit(1);\n\t}\n\tjanus_config_print_as(config, LOG_INFO);\n\tJANUS_LOG(LOG_INFO, \"\\n\");\n\tjanus_config_destroy(config);\n\t/* Done */\n\tFILE *file = fopen(destination, \"rb\");\n\tif(file == NULL) {\n\t\tg_free(target);\n\t\tJANUS_LOG(LOG_WARN, \"No destination file %s??\\n\", destination);\n\t\texit(1);\n\t}\n\tfseek(file, 0L, SEEK_END);\n\tsize_t fsize = ftell(file);\n\tfseek(file, 0L, SEEK_SET);\n\tJANUS_LOG(LOG_INFO, \"%s is %zu bytes\\n\", destination, fsize);\n\tfclose(file);\n\tg_free(target);\n\n\tJANUS_LOG(LOG_INFO, \"Bye!\\n\");\n\treturn 0;\n}\n"

As such, it doesn't provide any functionality per se other than implementing the means to set up a WebRTC media communication with a browser or application, exchanging JSON messages with it over different transports, and relaying RTP/RTCP and messages between clients and the server-side application logic they're attached to. Any specific feature/application is provided by server side plugins, that browsers can then contact via the server to take advantage of the functionality they provide. Example of such plugins can be implementations of applications like echo tests, conference bridges, media recorders, SIP gateways and the like.\n.TP\nThe reason for this is simple: we wanted something that would have a small footprint (hence a C implementation) and that we could only equip with what was really needed (hence pluggable modules). That is, something that would allow us to deploy either a full-fledged WebRTC server on the cloud, or a small nettop/box to handle a specific use case.\n.SH OPTIONS\n.TP\n.BR \\-h \", \" \\-\\-help\nPrint help and exit\n.TP\n.BR \\-V \", \" \\-\\-version\nPrint version and exit\n.TP\n.BR \\-b \", \" \\-\\-daemon\nLaunch Janus in background as a daemon (default=off)\n.TP\n.BR \\-p \", \" \\-\\-pid-file=\\fIpath\\fR\nOpen the specified PID file when starting Janus (default=none)\n.TP\n.BR \\-N \", \" \\-\\-disable-stdout\nDisable stdout based logging (default=off)\n.TP\n.BR \\-L \", \" \\-\\-log-stdout\nLog to stdout, even when the process is daemonized (default=off)\n.TP\n.BR \\-L \", \" \\-\\-log-file=\\fIpath\\fR\nLog to the specified file (default=stdout only)\n.TP\n.BR \\-H \", \" \\-\\-cwd-path=\\fIpath\\fR\nWorking directory for Janus daemon process (default=/)\n.TP\n.BR \\-i \", \" \\-\\-interface=\\fIipaddress\\fR\nInterface to use (will be the public IP)\n.TP\n.BR \\-P \", \" \\-\\-plugins-folder=\\fIpath\\fR\nPlugins folder (default=./plugins)\n.TP\n.BR \\-C \", \" \\-\\-config=\\fIfilename\\fR\nConfiguration file to use\n.TP\n.BR \\-F \", \" \\-\\-configs-folder=\\fIpath\\fR\nConfiguration files folder (default=./conf)\n.TP\n.BR \\-c \", \" \\-\\-cert-pem=\\fIfilename\\fR\nDTLS certificate\n.TP\n.BR \\-k \", \" \\-\\-cert-key=\\fIfilename\\fR\nDTLS certificate key\n.TP\n.BR \\-K \", \" \\-\\-cert-pwd=\\fItext\\fR\nDTLS certificate key passphrase (if needed)\n.TP\n.BR \\-S \", \" \\-\\-stun-server=\\fIaddress:port\\fR\nSTUN server(:port) to use, if needed (e.g., Janus behind NAT, default=none)\n.TP\n.BR \\-1 \", \" \\-\\-nat-1-1=\\fIips\\fR\nComma-separated list of public IPs to put in all host candidates, assuming a 1:1 NAT is in place (e.g., Amazon EC2 instances, default=none)\n.TP\n.BR \\-2 \", \" \\-\\-keep-private-host\nWhen nat-1-1 is used (e.g., Amazon EC2 instances), don't remove the private host, but keep both to simulate STUN (default=off)\n.TP\n.BR \\-E \", \" \\-\\-ice-enforce-list=\\fIlist\\fR\nComma-separated list of the only interfaces to use for ICE gathering; partial strings are supported (e.g., eth0 or eno1,wlan0, default=none)\n.TP\n.BR \\-X \", \" \\-\\-ice-ignore-list=\\fIlist\\fR\nComma-separated list of interfaces or IP addresses to ignore for ICE gathering; partial strings are supported (e.g., vmnet8,192.168.0.1,10.0.0.1 or vmnet,192.168., default=vmnet)\n.TP\n.BR \\-6 \", \" \\-\\-ipv6-candidates\nWhether to enable IPv6 candidates or not (default=off)\n.TP\n.BR \\-O \", \" \\-\\-ipv6-link-local\nWhether IPv6 link-local candidates should be gathered as well (default=off)\n.TP\n.BR \\-l \", \" \\-\\-libnice-debug\nWhether to enable libnice debugging or not (default=off)\n.TP\n.BR \\-f \", \" \\-\\-full-trickle\nDo full-trickle instead of half-trickle (default=off)\n.TP\n.BR \\-I \", \" \\-\\-ice-lite\nWhether to enable the ICE Lite mode or not (default=off)\n.TP\n.BR \\-T \", \" \\-\\-ice-tcp\nWhether to enable ICE-TCP or not (warning: only works with ICE Lite) (default=off)\n.TP\n.BR \\-Q \", \" \\-\\-min-nack-queue=\\fInumber\\fR\nMinimum size of the NACK queue (in ms) per user for retransmissions, no matter the RTT\n.TP\n.BR \\-t \", \" \\-\\-no-media-timer=\\fInumber\\fR\nTime (in s) that should pass with no media (audio or video) being received before Janus notifies you about this\n.TP\n.BR \\-W \", \" \\-\\-slowlink-threshold=\\fInumber\\fR\nNumber of lost packets (per s) that should trigger a 'slowlink' Janus API event to users (default=0, feature disabled)\n.TP\n.BR \\-r \", \" \\-\\-rtp-port-range=\\fImin\\-max\\fR\nPort range to use for RTP/RTCP\n.TP\n.BR \\-B \", \" \\-\\-twcc-period=\\fInumber\\fR\nHow often (in ms) to send TWCC feedback back to senders, if negotiated (default=200ms)\n.TP\n.BR \\-n \", \" \\-\\-server-name=\\fIname\\fR\nPublic name of this Janus instance (default=MyJanusInstance)\n.TP\n.BR \\-s \", \" \\-\\-session-timeout=\\fInumber\\fR\nSession timeout value, in seconds (default=60)\n.TP\n.BR \\-m \", \" \\-\\-reclaim-session-timeout=\\fInumber\\fR\nReclaim session timeout value, in seconds (default=0)\n.TP\n.BR \\-d \", \" \\-\\-debug-level=\\fI1\\-7\\fR\nDebug/logging level (0=disable debugging, 7=maximum debug level; default=4)\n.TP\n.BR \\-D \", \" \\-\\-debug-timestamps\nEnable debug/logging timestamps (default=off)\n.TP\n.BR \\-o \", \" \\-\\-disable-colors\nDisable color in the logging (default=off)\n.TP\n.BR \\-M \", \" \\-\\-debug-locks\nEnable debugging of locks/mutexes (very verbose!

This includes callbacks\n * the Janus core can use to receive log lines to process. Besides, as a\n * logger plugin is a shared object, and as such external to the\n * core itself, in order to be dynamically loaded at startup it needs\n * to implement the \\c create_l() hook as well, that should return a\n * pointer to the plugin instance. This is an example of such a step:\n *\n\\verbatim\nstatic janus_logger mylogger = {\n\t[..]\n};\n\njanus_logger *create(void) {\n\tJANUS_LOG(LOG_VERB, , \"%s created!\\n\", MY_LOGGER_NAME);\n\treturn &mylogger;\n}\n\\endverbatim\n *\n * This will make sure that your logger plugin is loaded at startup\n * by the Janus core, if it is deployed in the proper folder.\n *\n * As anticipated and described in the above example, a logger plugin\n * must basically be an instance of the \\c janus_logger type. As such,\n * it must implement the following methods and callbacks for the core:\n *\n * - \\c init(): this is called by the Janus core as soon as your logger\n * plugin is started; this is where you should setup your logger plugin\n * (e.g., static stuff and reading the configuration file);\n * - \\c destroy(): on the other hand, this is called by the core when it\n * is shutting down, and your logger plugin should too;\n * - \\c get_api_compatibility(): this method MUST return JANUS_LOGGER_API_VERSION;\n * - \\c get_version(): this method should return a numeric version identifier (e.g., 3);\n * - \\c get_version_string(): this method should return a verbose version identifier (e.g., \"v1.0.1\");\n * - \\c get_description(): this method should return a verbose description of your logger plugin (e.g., \"This is a logger that saves log lines on a database\");\n * - \\c get_name(): this method should return a short display name for your logger plugin (e.g., \"My Amazing Logger\");\n * - \\c get_package(): this method should return a unique package identifier for your logger plugin (e.g., \"janus.logger.mylogger\");\n * - \\c incoming_logline(): this callback informs the logger that a log line is available for consumption.\n *\n * All the above methods and callbacks are mandatory: the Janus core will\n * reject al logger plugin that doesn't implement any of the mandatory callbacks.\n *\n * Unlike other kind of modules (transports, plugins), the \\c init() method\n * here only passes the path to the configurations files folder, as loggers\n * never need to contact the Janus core themselves. This path can be used to\n * read and parse a configuration file for the logger plugin: the logger\n * plugins we made available out of the box use the package name as a\n * name for the file (e.g., \\c janus.logger.json.jcfg for the sample\n * logger plugin), but you're free to use a different one, as long\n * as it doesn't collide with existing ones. Besides, the existing logger\n * plugins use the same libconfig format for configuration files the core\n * uses (relying on the \\c janus_config helpers for the purpose) but\n * again, if you prefer a different format (XML, JSON, etc.) that's up to you.\n *\n * \\ingroup loggerapi\n * \\ref loggerapi\n */\n\n#ifndef JANUS_LOGGER_H\n#define JANUS_LOGGER_H\n\n#include <stdlib.h>\n#include <stdint.h>\n#include <stdio.h>\n#include <string.h>\n#include <ctype.h>\n#include <unistd.h>\n#include <inttypes.h>\n\n#include <glib.h>\n#include <jansson.h>\n\n#include \"../utils.h\"\n\n\n/*! \\brief Version of the API, to match the one logger plugins were compiled against */\n#define JANUS_LOGGER_API_VERSION\t3\n\n/*! \\brief Initialization of all logger plugin properties to NULL\n *\n * \\note All logger plugins MUST add this as the FIRST line when initializing\n * their logger plugin structure, e.g.:\n *\n\\verbatim\nstatic janus_logger janus_fake_logger_plugin =\n\t{\n\t\tJANUS_LOGGER_INIT,\n\n\t\t.init = janus_fake_init,\n\t\t[..]\n\\endverbatim\n */\n\n#define JANUS_LOGGER_INIT(...) {\t\t\t\\\n\t\t.init = NULL,\t\t\t\t\t\t\t\\\n\t\t.destroy = NULL,\t\t\t\t\t\t\\\n\t\t.get_api_compatibility = NULL,\t\t\t\\\n\t\t.get_version = NULL,\t\t\t\t\t\\\n\t\t.get_version_string = NULL,\t\t\t\t\\\n\t\t.get_description = NULL,\t\t\t\t\\\n\t\t.get_name = NULL,\t\t\t\t\t\t\\\n\t\t.get_author = NULL,\t\t\t\t\t\t\\\n\t\t.get_package = NULL,\t\t\t\t\t\\\n\t\t.incoming_logline = NULL,\t\t\t\t\\\n\t\t## __VA_ARGS__ }\n\n\n/*! \\brief The logger plugin session and callbacks interface */\ntypedef struct janus_logger janus_logger;\n\n\n/*! \\brief The logger plugin session and callbacks interface */\nstruct janus_logger {\n\t/*! \\brief Logger plugin initialization/constructor\n\t * @param[in] server_name Name of the Janus instance generating the logs\n\t * @param[in] config_path Path of the folder where the configuration for this logger plugin can be found\n\t * @returns 0 in case of success, a negative integer in case of error */\n\tint (* const init)(const char *server_name, const char *config_path);\n\t/*! \\brief Logger plugin deinitialization/destructor */\n\tvoid (* const destroy)(void);\n\n\t/*! \\brief Informative method to request the API version this logger plugin was compiled against\n\t *  \\note All logger plugins MUST implement this method and return JANUS_LOGGER_API_VERSION\n\t * to make this work, or they will be rejected by the core. */\n\tint (* const get_api_compatibility)(void);\n\t/*! \\brief Informative method to request the numeric version of the logger plugin */\n\tint (* const get_version)(void);\n\t/*! \\brief Informative method to request the string version of the logger plugin */\n\tconst char *(* const get_version_string)(void);\n\t/*! \\brief Informative method to request a description of the logger plugin */\n\tconst char *(* const get_description)(void);\n\t/*! \\brief Informative method to request the name of the logger plugin */\n\tconst char *(* const get_name)(void);\n\t/*! \\brief Informative method to request the author of the logger plugin */\n\tconst char *(* const get_author)(void);\n\t/*! \\brief Informative method to request the package name of the logger plugin (what will be used in web applications to refer to it) */\n\tconst char *(* const get_package)(void);\n\n\t/*! \\brief Method to notify the logger plugin that a new log line is available\n\t * \\details All log lines are notified as a string\n\t * \\note Do NOT handle the log line directly in this method.

If you want to check the previous version of\n *\t\tJanus instead (i.e., <code>0.x</code>, a.k.a. \"legacy\") click\n *\t\t<a href=\"https://janus-legacy.conf.meetecho.com\">here</a> instead.\n * </div>\n *\n * \\par Developer Documentation for the Janus WebRTC server\n * This is the main developer documentation for the Janus WebRTC\n * Server, generated with the help of\n * <a href=\"http://www.doxygen.org\">Doxygen</a>. Make sure you\n * check the \\ref DEPS before attempting a compilation. If you are\n * interested in how to compile, install and use Janus,\n * checkout the \\ref README information. A \\ref FAQ page is also available,\n * as well as an overview on \\ref CHANGELOG.\n *\n * \\par A general purpose WebRTC server\n * The Janus WebRTC Server has been conceived as a <tt>general purpose</tt>\n * server. As such, it doesn't provide any functionality per se\n * other than implementing the means to set up a WebRTC media communication\n * with a browser, exchanging JSON messages with it, and relaying RTP/RTCP\n * and messages between browsers and the server-side application logic they're attached to. Any specific\n * feature/application needs to be implemented in server side plugins,\n * that browsers can then contact via the Janus core to take advantage of\n * the functionality they provide. Example of such plugins can be\n * implementations of applications like echo tests, conference bridges,\n * media recorders, SIP gateways and the like.\n *\n * The reason for this is simple: we wanted something that would have a\n * <tt>small footprint</tt> (hence a C implementation) and that we could only\n * equip with what was <tt>really needed</tt> (hence pluggable modules). That is,\n * something that would allow us to deploy either a full-fledged WebRTC\n * server on the cloud, or a small nettop/box to handle a specific use case.\n *\n * \\par Architecture and APIs\n * The core of the server is specified in the \\ref core section. The protocols\n * implemented in the Janus core are listed in the \\ref protocols group\n * instead. A list of plugins provided out of the box by Meetecho are\n * documented in the \\ref pluginslist page: these plugins can be changed\n * or extended to match your requirements, or just used as a simple\n * reference should you be interested in writing a new plugin from\n * scratch (and you're definitely welcome to!). A \\ref pluginapi to\n * create new plugins, or understand how they're conceived, is documented\n * as well. A documentation on the available API transports and the\n * HTTP/WebSocket JavaScript API to use Janus and the plugins it\n * makes available in your web application can be found in the \\ref JS\n * and \\ref rest pages. New API transports can be created referring to\n * the \\ref transportapi page. If you're interested in monitoring Janus\n * resources, you can refer to the \\ref admin page. Event handler\n * plugins can also be used for the purpose: refer to the \\ref eventhandlers\n * and, for more developer oriented info, to the \\ref eventhandlerapi\n * page if you're interested in creating your own. For what concerns logging,\n * out of the box Janus supports printing the output to \\c stdout and saving\n * to a local file, but logging can also be extended via additional plugins:\n * refer to the \\ref loggerapi for more details, and to learn how to write\n * your own. You can check the \\ref ide page for some details about how\n * to setup your local development environment for Janus..\n *\n * Janus also supports \\ref recordings out of the box, so check the\n * related documentation to know more about how that works.\n *\n * Finally, some information on how to deploy Janus and your web\n * applications that want to make use of it are provided in the \\ref deploy\n * page. If you're interested in starting Janus as a service/daemon rather\n * than launching it normally, check the information provided in the\n * \\ref service page. Some additional \\ref resources are also listed in\n * case you're interested in talking to Janus from different languages\n * and platforms.\n *\n * To conclude, the \\ref debug page contains info on how you can help us\n * fixing issues you might encounter along the road.\n *\n * \\section copyright Copyright and author\n *\n * Janus WebRTC Server © 2014-2026 <a href=\"https://www.meetecho.com/\">Meetecho</a> (https://www.meetecho.com/)\n *\n * \\author Lorenzo Miniero <lorenzo@meetecho.com> ( \\ref CREDITS )\n *\n * \\section license License\n * This program is free software, distributed under the terms of\n * the GNU General Public License Version 3.

These\n * interfaces are described in more detail in the \\ref plainhttp \\ref WS\n * \\ref rabbit \\ref apimqtt \\ref apinanomsg and \\ref unix documentation respectively, and all allow clients to\n * take advantage of the features provided by Janus and the functionality\n * made available by its plugins. Considering most clients will be web browsers,\n * a common choice will be to rely on either the REST or the WebSockets\n * interface for the purpose. To make things easier for web\n * developers, a JavaScript library (\\c janus.js) is available that can\n * make use of both interfaces using exactly the same API. This library\n * eases the task of creating sessions with the Janus core, attaching WebRTC\n * users to plugins, send and receive requests and events to the plugins\n * themselves and so on. For real examples of how this library can be\n * used, check the demos in the \\b html folder of this package. Notice\n * that the \\c janus.js library makes use of the features made available\n * by the <a href=\"https://github.com/webrtc/adapter\">webrtc-adapter</a>\n * shim, which means that your web application should always include it\n * as a dependency. For instance, all the demos link to it externally via\n * <a href=\"https://cdnjs.com/\">cdnjs.com</a>.\n *\n * \\note The current \\c janus.js library allows you to provide custom implementations of\n * certain dependencies, in order to make it easier to integrate with other JavaScript\n * libraries and frameworks. Using this feature you can ensure \\c janus.js does not (implicitly)\n * depend on certain global variables. Two implementations are included in \\c janus.js itself:\n *\n *  -# \\ref js-default-deps which relies on native browser APIs,\n *     which in turn require somewhat more modern browsers\n *  -# \\ref js-old-deps which uses jQuery (http://jquery.com/) instead,\n *     and should provide equivalent behaviour to previous versions of \\c janus.js\n *\n * By default \\ref js-default-deps will be used, but you can override this\n * when initialising the Janus library and pass a custom dependencies object instead.\n * For details, refer to: \\ref js-dependencies\n *\n * In general, when using the Janus features, you would normally do the following:\n *\n * -# include the Janus JavaScript library in your web page;\n * -# initialize the Janus JavaScript library and (optionally) passing its dependencies;\n * -# connect to the server and create a session;\n * -# create one or more handles to attach to a plugin (e.g., echo test and/or streaming);\n * -# interact with the plugin (sending/receiving messages, negotiating a PeerConnection);\n * -# eventually, close all the handles and shutdown the related PeerConnections;\n * -# destroy the session.\n *\n * The above steps will be presented in order, describing how you can use\n * the low level API to accomplish them. Consider that in the future we might\n * provide higher level wrappers to this API to address specific needs, e.g.,\n * a higher level API for each plugin: this would make it even easier to use\n * the server features, as a high level API for the streaming plugin, for\n * instance, may just ask you to provide the server address and the ID of\n * the \\c &lt;video&gt; element to display the stream in, and would take care of all the\n * above mentioned steps on your behalf. Needless to say, you're very welcome\n * to provide wrapper APIs yourself, if you feel a sudden urge to do so! :-)\n *\n * \\section janusjs Using janus.js\n *\n * As a first step, you should include the Janus library in your project.\n * Depending on your needs you can either use \\c janus.js or one of the generated\n * JavaScript module variants of it. For available module syntaxes and how to build the\n * corresponding variants, see: \\ref js-modules\n *\n\\verbatim\n<script type=\"text/javascript\" src=\"janus.js\" ></script>\n\\endverbatim\n *\n * The core of the JavaScript API is the \\c Janus object. This object needs\n * to be initialized the first time it is used in a page. This can be done\n * using the static \\c init method of the object, which accepts the\n * following options:\n *\n * - \\c debug: whether debug should be enabled on the JavaScript console, and what levels\n *   - \\c true or \\c \"all\": all debuggers enabled (Janus.trace, Janus.debug, Janus.log, Janus.warn, Janus.error)\n *   - array (e.g., <code>[\"trace\", \"warn\"]</code>): only enable selected debuggers (allowed tokens: trace, debug, log, warn, error)\n *   - \\c false: disable all debuggers\n * - \\c callback: a user provided function that is invoked when the initialization is complete\n * - \\c dependencies: a user provided implementation of Janus library dependencies\n *\n * Here's an example:\n *\n *\n \\verbatim\nJanus.init({\n   debug: true,\n   dependencies: Janus.useDefaultDependencies(), // or: Janus.useOldDependencies() to get the behaviour of previous Janus versions\n   callback: function() {\n\t   // Done!\n   }\n});\n \\endverbatim\n *\n * \\note When using one of the JavaScript module variants of \\c janus.js, you\n * will need to import the \\c Janus symbol from the module first. See also: \\ref js-modules\n * For example, using the ECMAScript module variant, the above example should be altered to:\n *\n *\n \\verbatim\nimport * as Janus from './janus.es.js'\n\nJanus.init({\n   debug: true,\n   dependencies: Janus.useDefaultDependencies(), // or: Janus.useOldDependencies() to get the behaviour of previous Janus versions\n   callback: function() {\n\t   // Done!\n   }\n});\n \\endverbatim\n *\n * Once the library has been initialized, you can start creating sessions.\n * Normally, each browser tab will need a single session with the server: in\n * fact, each Janus session can contain several different plugin handles\n * at the same time, meaning you can start several different WebRTC sessions\n * with the same or different plugins for the same user using the same\n * Janus session. That said, you're free to set up different Janus\n * sessions in the same page, should you prefer so.\n *\n * Creating a session is quite easy. You just need to use the \\c new constructor\n * to create a new \\c Janus object that will handle your interaction with the\n * server. Considering the dynamic and asynchronous nature of Janus sessions\n * (events may occur at any time), there are several properties and callbacks you\n * can configure when creating a session:\n *\n * - \\c server: the address of the server as a specific address (e.g.,\n * http://yourserver:8088/janus to use the plain HTTP API or ws://yourserver:8188/\n * for WebSockets) or as an array of addresses to try sequentially to allow\n * automatic for fallback/failover during setup;\n * - \\c iceServers: a list of STUN/TURN servers to use (a default STUN server\n * will be used if you skip this property);\n * - \\c withCredentials: whether the \\c withCredentials property of XHR requests\n * should be enabled or not (false by default, and only valid when using HTTP\n * as a transport, ignored for WebSockets);\n * - \\c max_poll_events: the number of events that should be returned when polling;\n * the default is 1 (polling returns an object), passing a higher number will\n * have the backend return an array of objects instead (again, only valid for\n HTTP usage as this is strictly related to long polling, ignored for WebSockets);\n * - \\c destroyOnUnload: whether we should destroy automatically try and\n * destroy this session via Janus API when \\c onbeforeunload is called (true by default);\n * - \\c token , \\c apisecret: optional parameters only needed in case you're \\ref auth ;\n * - a set of callbacks to be notified about events, namely:\n * \t\t- \\c success: the session was successfully created and is ready to be used;\n * \t\t- \\c error: the session was NOT successfully created;\n * \t\t- \\c destroyed: the session was destroyed and can't be used any more.\n *\n * These properties and callbacks are passed to the method as properties\n * of a single parameter object: that is, the \\c Janus constructor takes a\n * single parameter, which although acts as a container for all the available\n * options. The \\c success callback is where you typically start your application\n * logic, e.g., attaching the peer to a plugin and start a media session.\n *\n * Here's an example:\n *\n \\verbatim\nvar janus = new Janus(\n    {\n        server: 'http://yourserver:8088/janus',\n        success: function() {\n            // Done! attach to plugin XYZ\n        },\n        error: function(cause) {\n            // Error, can't go on...\n        },\n        destroyed: function() {\n            // I should get rid of this\n        }\n    });\n \\endverbatim\n *\n * As anticipated, the server may be a specific address, e.g.:\n *\n \\verbatim\nvar janus = new Janus(\n    {\n        server: 'http://yourserver:8088/janus',\n                // or\n        server: 'ws://yourserver:8188/',\n        [..]\n \\endverbatim\n *\n * or an array of addresses. Such an array can be especially useful if\n * you want the library to first check if the WebSockets server is\n * reachable and, if not, fallback to plain HTTP, or just to provide\n * a link multiple instances to try for failover. This is an example of\n * how to pass a 'try websockets and fallback to HTTP' array:\n *\n \\verbatim\nvar janus = new Janus(\n    {\n        server: ['ws://yourserver:8188/','http://yourserver:8088/janus'],\n        [..]\n \\endverbatim\n *\n * Once created, this object represents your session with the server.\n * you can interact with a \\c Janus object in several different ways.\n * In particular, the following properties and methods are defined:\n *\n * - \\c getServer(): returns the address of the server;\n * - \\c isConnected(): returns \\c true if the Janus instance is connected\n * to the server, \\c false otherwise;\n * - \\c getSessionId(): returns the unique Janus session identifier;\n * - \\c attach(parameters): attaches the session to a plugin, creating a handle;\n * more handles to the same or different plugins can be created at the same time;\n * - \\c destroy(parameters): destroys the session with the server, and closes\n * all the handles (and related PeerConnections) the session may have with any plugin as well.\n *\n * The most important property is obviously the \\c attach() method, as\n * it's what will allow you to exploit the features of a plugin to manipulate\n * the media sent and/or received by a PeerConnection in your web page.\n * This method will create a plugin handle you can use for the purpose,\n * for which you can configure properties and callbacks when calling the\n * \\c attach() method itself. As for the \\c Janus constructor, the \\c attach()\n * method takes a single parameter that can contain any of the following\n * properties and callbacks:\n *\n * - \\c plugin: the unique package name of the plugin (e.g., \\c janus.plugin.echotest );\n * - \\c opaqueId: an optional opaque string meaningful to your application (e.g., to map all the handles of the same user);\n * - a set of callbacks to be notified about events, namely:\n * \t\t- \\c success: the handle was successfully created and is ready to be used;\n * \t\t- \\c error: the handle was NOT successfully created;\n * \t\t- \\c consentDialog: this callback is triggered just before \\c getUserMedia is called\n * (parameter=<b>true</b>) and after it is completed (parameter=<b>false</b>); this means it can\n * be used to modify the UI accordingly, e.g., to prompt the user about the need to accept the device access consent requests;\n * \t\t- \\c webrtcState: this callback is triggered with a <b>true</b> value\n * when the PeerConnection associated to a handle becomes active (so ICE, DTLS and\n * everything else succeeded) from the Janus perspective, while <b>false</b> is\n * triggered when the PeerConnection goes down instead; useful to figure out\n * when WebRTC is actually up and running between you and Janus (e.g., to notify\n * a user they're actually now active in a conference); notice that in case\n * of <b>false</b> a reason string may be present as an optional parameter;\n * \t\t- \\c connectionState: this callback is triggered when the connection state for the\n * PeerConnection associated to the handle changes: the argument of the callback\n * is the new state as a string (e.g., \"connected\" or \"failed\");\n * \t\t- \\c iceState: this callback is triggered when the ICE state for the\n * PeerConnection associated to the handle changes: the argument of the callback\n * is the new state as a string (e.g., \"connected\" or \"failed\");\n * \t\t- \\c mediaState: this callback is triggered when Janus starts or stops\n * receiving your media: for instance, a \\c mediaState with mid=<b>0</b>, type=<b>audio</b>\n * and on=<b>true</b> means Janus started receiving the audio stream identified\n * by mid \\c b in the offer/answer exchange and transceivers (or started\n * getting them again after a pause of more than a second); a \\c mediaState with\n * type=<b>video</b> and on=<b>false</b> means Janus hasn't received any video\n * from you in the last second, after a start was detected before; useful to\n * figure out when Janus actually started handling your media, or to detect\n * problems on the media path (e.g., media never started, or stopped at some time);\n * \t\t- \\c slowLink: this callback is triggered when Janus reports trouble\n * either sending or receiving media on the specified PeerConnection, typically\n * as a consequence of too lost packets detected to/from the user in the\n * last second: for instance, a \\c slowLink with uplink=<b>true</b> means\n * you notified several missing packets from Janus, while uplink=<b>false</b>\n * means Janus is not receiving all your packets; useful to figure out when\n * there are problems on the media path (e.g., excessive loss), in order to\n * possibly react accordingly (e.g., decrease the bitrate if most of our\n * packets are getting lost);\n * \t\t- \\c onmessage: a message/event has been received from the plugin;\n * \t\t- \\c onlocaltrack: a local \\c MediaStreamTrack is available and ready to be displayed;\n * \t\t- \\c onremotetrack: a remote \\c MediaStreamTrack is available and ready to be displayed;\n * \t\t- \\c ondataopen: a Data Channel is available and ready to be used;\n * \t\t- \\c ondata: data has been received through the Data Channel;\n * \t\t- \\c oncleanup: the WebRTC PeerConnection with the plugin was closed;\n * \t\t- \\c detached: the plugin handle has been detached by the plugin itself,\n * and so should not be used anymore.\n *\n * Here's an example:\n *\n \\verbatim\n// Attach to echo test plugin, using the previously created janus instance\njanus.attach(\n    {\n        plugin: \"janus.plugin.echotest\",\n        success: function(pluginHandle) {\n            // Plugin attached!

The only step that may require a little more\n * effort to understand is the PeerConnection negotiation, but again, if\n * you're familiar with the WebRTC API, the \\c Handle actually makes it\n * a lot easier.\n *\n * The idea behind it's usage is the following:\n *\n * -# you use \\c attach() to create a \\c Handle object;\n * -# in the \\c success callback, your application logic can kick in: you may\n * want to send a message to the plugin (<code>send({msg})</code>), negotiate\n * a PeerConnection with the plugin right away ( \\c createOffer followed\n * by a <code>send({msg, jsep})</code>) or wait for something to happen to do anything;\n * -# the \\c onmessage callback tells you when you've got messages from the plugin;\n * if the \\c jsep parameter is not null, just pass it to the library, which will take\n * care of it for you; if it's an \\b OFFER use \\c createAnswer (followed by a\n * <code>send({msg, jsep})</code> to close the loop with the plugin), otherwise use\n * \\c handleRemoteJsep ;\n * -# whether you took the initiative to set up a PeerConnection or the plugin did,\n * the \\c onlocaltrack and/or the \\c onremotetrack callbacks will provide\n * you with info on media tracks you can display or play in your page;\n * -# each plugin may allow you to manipulate what should flow through the\n * PeerConnection channel: the \\c send method and \\c onmessage callback\n * will allow you to handle this interaction (e.g., to tell the plugin\n * to mute your stream, or to be notified about someone joining a virtual room),\n * while the \\c ondata callback is triggered whenever data is received\n * on the Data Channel, if available (and the \\c ondataopen callback\n * will tell you when a Data Channel is actually available).\n *\n * The following paragraphs will delve a bit deeper in the negotiation\n * mechanism provided by the \\c Handle API, in particular describing\n * the properties and callbacks that may be involved. To follow the approach\n * outlined by the W3C WebRTC API, this negotiation mechanism is heavily\n * based on asynchronous methods as well. Notice that the following paragraphs\n * address the first negotiation step, that is the one to create a new\n * PeerConnection from scratch: to know how to originate or handle a\n * renegotiation instead (e.g., to add/remove/replace a media source, or\n * force an ICE restart) check the \\ref renegotiation section instead.\n *\n * - \\c createOffer takes a single parameter, that can contain any of the\n * following properties and callbacks:\n *   - \\c tracks: you can use this property to tell the library which media (audio/video/data)\n * you're interested in, and whether you're going to send and/or receive any of them; by default\n * no device is captured, and Data Channels are disabled as well; incoming audio and video\n * is instead autoaccepted unless you tell the library otherwise; the same property can also\n * be used to update sessions (e.g., to add/remove/replace tracks); this option is an array of\n * objects, where each object can take any of the following properties:\n *     - \\c type: mandatory, must be one of \"audio\", \"video\", \"screen\" and \"data\";\n *     - \\c mid: to address existing tracks (e.g., when answering or updating sessions),\n * the \\c mid property specifies that the info in the related track object\n * are specific to that target; notice that this is ignored in a first \\c createOffer ,\n * as mid values are created by the browser automatically and cannot be forced;\n *     - \\c capture: in case something must be captured (e.g., a microphone for\n * \"audio\" or a \"webcam\" for video), the \\c capture property can be used to\n * dictate what and how; passing \\c true asks for the default device, but\n * \\c getUserMedia (for audio/video) or \\c getDisplayMedia (for screen sharing)\n * constraints can be passed as well as objects, and in case those will be\n * used instead; passing a \\c MediaStreamTrack instance will tell the library\n * not to capture anything, but use the provided track as a source instead;\n *     - \\c simulcast: \\c true/false, for video, whether simulcast should be used for this track;\n *     - \\c svc: for video, the scalability mode to enable, in case SVC needs to be\n * used for this track; notice that SVC support is experimental in Janus, and not\n * fully supported in all browsers either;\n *     - \\c recv: \\c true/false , whether audio or video should be received\n * as well; in case \\c capture is set but \\c recv is false, then this means\n * you're asking for a \"sendonly\" track;\n *     - \\c add: \\c true/false , whether a new track should be added (default is true for offers);\n *     - \\c replace: \\c true/false , whether a provided \\c capture should replace what\n * is being captured for the specified track;\n *     - \\c remove: \\c true/false , whether the local track that's currently captured\n * should be removed, meaning nothing will be sent for that specific stream;\n *     - \\c dontStop: \\c true/false , whether a track that is being added right\n * now should \\b NOT be stopped when the track is removed; this is helpful whenever,\n * for instance, an external track is being provided to \\c capture , and the application\n * wants to keep control on the life cycle of the \\c MediaStreamTrack instance;\n *     - \\c transforms: in case Insertable Streams need to be used (e.g., for end-to-end\n * encryption), the \\c sender and/or \\c receiver transform functions for this track can\n * be provided in the \\c transforms property;\n *   - \\c trickle: \\c true/false, to tell the library whether you want\n * Trickle ICE to be used (true, the default) or not (false);\n *   - a set of callbacks to be notified about the result, namely:\n *     - \\c success: the session description was created (attached as a parameter) and is ready to be sent to the plugin;\n *     - \\c error: the session description was NOT successfully created;\n *     - \\c customizeSdp: you can modify the sdp generated by the webrtc engine if you need;\n * - \\c createAnswer takes the same options as createOffer, but requires\n * an additional one as part of the single parameter argument:\n *   - \\c jsep: the session description sent by the plugin (e.g., as received\n * in an \\c onmessage callback) as its OFFER.\n *\n * Whether you use \\c createOffer or \\c createAnswer depending on the scenario,\n * you should end up with a valid \\c jsep object returned in the \\c success\n * callback. You can attach this \\c jsep object to a message in a \\c send request\n * to pass it to the plugin, and have Janus negotiate a PeerConnection\n * with your application.\n *\n * Here's an example of how to use \\c createOffer, taken from the Echo Test demo page:\n *\n \\verbatim\n// Attach to echo test plugin\njanus.attach(\n    {\n        plugin: \"janus.plugin.echotest\",\n        success: function(pluginHandle) {\n            // Negotiate WebRTC\n            echotest = pluginHandle;\n            echotest.createOffer(\n                {\n                    // We want bidirectional audio and video, plus data channels\n                    tracks: [\n                        { type: 'audio', capture: true, recv: true },\n                        { type: 'video', capture: true, recv: true },\n                        { type: 'data' },\n                    ],\n                    success: function(jsep) {\n                        // Got our SDP!

A more complex example (e.g., a call using the\n * Video Call, SIP or NoSIP plugin, or a videoconfecence using the Video Room)\n * would involve both, allowing you to either send offers to a plugin,\n * or receive some from them. Handling this is just a matter of checking\n * the \\c type of the \\c jsep object and reacting accordingly.\n *\n * \\section renegotiation Updating an existing PeerConnection (with or without renegotiations)\n * While the JavaScript APIs described above will suffice for most of the\n * common scenarios, there are cases when updates on a PeerConnection may\n * be needed. This can happen whenever, for instance, you want to add a\n * new media source (e.g., add video to an audio only call), replace an\n * existing one (e.g., switch from capturing the camera to sharing your\n * screen), or trigger an ICE restart because of a network change. While\n * adding or removing tracks requires a renegotiation, which means a new SDP\n * offer/answer round to update the existing PeerConnection, just replacing\n * a track can be done without any further SDP exchange. In both cases,\n * the \\c tracks property introduced before can be used to update a session.\n *\n * To just replace an existing track (e.g., changing the camera used to\n * capture the video we're sending) the \\c replaceTracks handle method can\n * be used. Using it is quite trivial, since you simply need to provide a\n * list of tracks you want to update, identify them somehow (e.g., via\n * their \\c mid ), and provide the new \\c capture property. A simple\n * example that shows how to replace a video track with a specific camera\n * identified by its \\c deviceId is the following:\n *\n \\verbatim\nechotest.replaceTracks({\n    tracks: [\n        {\n            type: 'video',\n            mid: '1',    // We assume mid 1 is video\n            capture: { deviceId: { exact: videoDeviceId } }\n        }\n    ]\n});\n \\endverbatim\n *\n * In case a new track needs to be added to a session, or an existing\n * track be removed, instead, a renegotiation is indeed needed, because\n * it requires changes to be signalled to the other party. In that case,\n * a renegotiation happens exactly as new sessions do, meaning that you\n * either perform a new \\c createOffer followed by a \\c handleRemoteJsep\n * with the updated answer, or you handle an incoming updated offer and\n * provide an updated answer via \\c createAnswer : the library will\n * automatically understand from context if you're creating a new session\n * or updating an existing one.\n *\n * When updating a session to add or remove tracks, you need to provide\n * an updated \\c tracks property as well. It's important to only include\n * in this \\c tracks property a list of tracks you want to change: omitting\n * existing tracks will result in the library not making any change to\n * them. This means that a \\c createOffer without a \\c tracks property,\n * for instance, will simply generate a new offer without applying any\n * change (which, as we'll see later, can be useful in some cases, e.g.,\n * ICE restarts).\n *\n * Depending on what you want to update, you'll need to set one of the\n * following properties to \\c true in the related track object:\n *\n * - \\c add: adds a new track to the session;\n * - \\c replace: replaces an existing track in the session (similar to\n * what \\c replaceTracks does, but within the context of a renegotiation);\n * - \\c remove: removes an existing track from a session (the direction of\n * the related m-line will be changed to either \"recvonly\" or \"inactive\",\n * depending on whether there's incoming media as well or not).\n *\n * Notice that these properties are only processed when you're trying a\n * renegotiation, and will be ignored when creating a new PeerConnection.\n * These properties don't replace the existing \\c track properties, but go\n * along with them. For instance, when adding a new video stream, or\n * replacing an existing one, you can still use the video related properties\n * as before, e.g., to pass a specific device ID or asking for a screenshare\n * instead of a camera. As anticipated, omitting info on existing tracks\n * will leave them untouched.\n *\n * It's important to point out that, as for negotiations that result in\n * the creation of a new PeerConnection in the first place, how to perform\n * a renegotiation in practice will typically vary depending on the plugin\n * that you're trying to do it for. Some plugins may allow you to offer\n * a renegotiation, others may require you to send a different request\n * instead in order to trigger a renegotiation from the plugin. As it\n * will be clearer later, this is especially true for ICE restarts. As\n * such, apart from the generic and core-related definitions introduced\n * in this section, please refer to the documentation for each individual\n * plugin for more information about how to perform renegotiations in\n * specific use cases.\n *\n * Here's a simple example of how you can remove the local video capture\n * in a session, e.g., in the EchoTest demo:\n *\n \\verbatim\n// Remove local video\nechotest.createOffer(\n    {\n        tracks: [{ type: 'video', mid: '1', remove: true }],\n        success: function(jsep) {\n            echotest.send({ message: { video: true }, jsep: jsep })\n        },\n        error: function(error) {\n            bootbox.alert('WebRTC error... ' + error.message);\n        }\n    });\n \\endverbatim\n *\n * This other example shows how you can add a new video stream, e.g.,\n * a screen share, to an existing PeerConnection instead:\n *\n \\verbatim\n// Add local video\nechotest.createOffer(\n    {\n        tracks: [{ type: 'screen', add: true, capture: true }],\n        success: function(jsep) {\n            echotest.send({ message: { video: true }, jsep: jsep })\n        },\n        error: function(error) {\n            bootbox.alert('WebRTC error... ' + error.message);\n        }\n    });\n \\endverbatim\n *\n * Notice that renegotiations involving media changes (both local and remote)\n * will likely result in new calls to the \\c onlocaltrack and \\c onremotetrack\n * application callbacks: as such, be prepared to see those callbacks called\n * for the same PeerConnection more than once during the course of a media session.\n *\n * \\section restarts ICE restarts\n * While ICE restarts can be achieved with a renegotiation, they're complex\n * enough to deserve a specific subsection. In fact, ICE restarts don't\n * address changes in the media, but in the underlying transport itself.\n * They're used, for instance, when there's a network change (e.g., the\n * IP address changed, or the user switched from WiFi to 4G). In order for\n * this to work, new candidates must be exchanged, and connectivity checks\n * must be restarted in order to find the new optimal path.\n *\n * With \\c janus.js, you can only force an ICE restart when sending a new\n * offer. In order to do so, all you need to do is add `iceRestart :true`\n * to your `createOffer` call, and an ICE restart will be requested. The\n * following example shows how this can be done with the EchoTest:\n *\n \\verbatim\nechotest.createOffer(\n    {\n        iceRestart: true,\n        success: function(jsep) {\n            echotest.send({ message: { audio: true, video: true }, jsep: jsep});\n        }\n    });\n \\endverbatim\n *\n * Notice how, in this particular example, we're not asking for any change\n * on the media streams, but just an ICE restart, which is why we don't\n * provide a \\c tracks property at all: as a consequence, the library won't\n * make any changes to the existing streams, but only generate a new offer.\n * If successful, as soon as the answer is received, the client and Janus\n * will restart the ICE process and find a new path for the media packets.\n *\n * Notice that, with Janus and its plugins, you won't always be able to\n * force an ICE restart by sending a new SDP offer yourself: some plugins,\n * like the Streaming plugin for instance, will want to always send an\n * offer themselves, which means they'll be the ones actually forcing the\n * ICE restart from a negotiation perspective. In order to still allow\n * users to actually originate the process, all the stock Janus plugins\n * that assume they'll be sending offers for some or all of their media\n * streams also expose APIs to force an ICE restart from the server side.\n * You can learn more about this on a plugin level basis\n * <a target=\"_blank\" href=\"https://github.com/meetecho/janus-gateway/pull/753\">here</a> and\n * <a target=\"_blank\" href=\"https://github.com/meetecho/janus-gateway/pull/1099\">here</a>.\n * Besides, make sure you read the documentation for each of the plugins\n * you're interested in using ICE restarts for, as the details for how\n * to perform it properly are typically provided there.\n *\n * <hr>\n *\n * This is it!

This may be useful if you are looking to build just the JavaScript modules without\n *    incurring the overhead of a full build of Janus.\n *\n * As an alternative to generating the module and copying it to your project, you can also tweak\n * your module bundler to use \\c janus.js directly from the official Janus repository. See more\n * details (including concrete instructions for Webpack): \\ref js-webpack\n *\n * \\section auto-build-js-modules Building modules using make\n * Each supported variant may be enabled by passing a corresponding \\c --enable-javascript-*-module flag\n * (with or without a \\c =yes directive) to \\c configure before invoking \\c make to build Janus.\n * Please note: if you do not pass any such flag, by default no modules will be built.\n *\n * The following table provides a summary of available module formats and their corresponding \\c configure options:\n *\n * <table class=\"table table-striped\">\n * <tr><th>Module format (syntax)</th><th>File name</th><th>configure flag to pass</th></tr>\n * <tr><td>ECMAScript</td><td>janus.es.js</td><td>\\c --enable-javascript-es-module</td></tr>\n * <tr><td>Universal Module Definition (UMD)</td><td>janus.umd.js</td><td>\\c --enable-javascript-umd-module</td></tr>\n * <tr><td>CommonJS</td><td>janus.cjs.js</td><td>\\c --enable-javascript-common-js-module</td></tr>\n * <tr><td>Immediately Invoked Function Expression (IIFE)</td><td>janus.iife.js</td><td>\\c --enable-javascript-iffe-module</td></tr>\n * </table>\n *\n * The \\c --enable-all-js-modules shortcut is available, in case you want to enable and build them all.\n *\n * When built and installed, these module variants may be found in the \\c $PREFIX/share/janus/javascript\n * folder, alongside the \\c janus.js file itself (assuming \\c $PREFIX the installation directory passed to \\c configure).\n *\n * \\note Building the JavaScript modules still requires NPM and may involve an \\c install which means \\c npm must be able\n * to download dependencies. By default \\c configure will attempt to auto-detect available \\c npm on your PATH, but\n * if you have installed NPM outside the PATH you can override this by passing the (full) path to your \\c npm executable, e.g.:\n *\n \\verbatim\n ./configure NPM=/path/to/my/custom/npm --enable-javascript-es-module=yes\n \\endverbatim\n *\n * \\section manual-build-modules Building modules manually with NPM\n * You can also opt to build modules by invoking \\c npm manually. The project root folder contains the necessary\n * configuration files to get you started:\n *\n \\verbatim\n npm install\n npm run rollup -- --o /path/to/desired/output/file-name.js --f cjs # or es, iffe, umd, amd, ...\n \\endverbatim\n *\n * Using \\c npm directly is useful if you want to build the JavaScript modules only, without building Janus itself\n * or if you are looking for advanced customisation options or alternative formats which are not integrated in \\c configure yet.\n * As you may have surmised from the example command, the actual build consists mostly of invoking \\c rollup with the\n * correct parameters. For more information on available parameters, please refer to the \\c rollup documentation:\n *\n * -# https://rollupjs.org/#command-line-flags\n * -# https://rollupjs.org/#configuration-files\n *\n * \\section js-webpack Using janus.js directly with Webpack and other bundlers\n *\n * Generating a converted version of \\c janus.js and copying it to your project is not always the best\n * solution. In many situations it may be preferred to let your JavaScript module bundler (e.g.\n * <a href=\"https://webpack.js.org\">Webpack</a>) grab the file directly from the official Janus repository.\n * Doing that you can manage \\c janus.js just like any other dependency coming from Github or the npm Registry,\n * getting rid of the manual copy step and letting the bundler take care of version management, updates\n * and downloads.\n *\n * Of course, the first step is to include the official Janus repository as a dependency in your\n * project by adding it to your \\c packages.json file.\n *\n \\verbatim\n {\n   \"dependencies\": {\n     \"janus-gateway\": \"git://github.com/meetecho/janus-gateway.git\"\n   }\n }\n \\endverbatim\n *\n * That will automatically drag in the dependency on the appropriate version of the\n * <a href=\"https://www.npmjs.com/package/webrtc-adapter\">WebRTC Adapter</a> from the npm Registry.\n * But \\c janus.js expects such adapter to be available as a global variable.\n * So we have to make that happen for it to work properly. In the case of Webpack, is as easy as\n * adding this to your \\c webpack.config.js file.\n \\verbatim\n const webpack = require('webpack');\n\n module.exports = {\n   plugins: [\n     // janus.js does not use 'import' to access to the functionality of webrtc-adapter,\n     // instead it expects a global object called 'adapter' for that.\n     // Let's make that object available.\n     new webpack.ProvidePlugin({ adapter: ['webrtc-adapter', 'default'] })\n   ]\n };\n \\endverbatim\n *\n * On the other hand, \\c janus.js defines the \\c Janus object globally. So a small tweak is also\n * needed to serve such object via \\c export. That can be done using\n * <a href=\"https://webpack.js.org/loaders/exports-loader/\">exports-loader</a> and adding this to\n * \\c webpack.config.js\n \\verbatim\n module.exports = {\n   module: {\n     rules: [\n       // janus.js does not use 'export' to provide its functionality to others, instead\n       // it creates a global variable called 'Janus' and expects consumers to use it.\n       // Let's use 'exports-loader' to simulate it uses 'export'.\n       {\n         test: require.resolve('janus-gateway'),\n         loader: 'exports-loader',\n          options: {\n            exports: 'Janus',\n          },\n       }\n     ]\n   }\n };\n \\endverbatim\n *\n * With that extra configuration, the official \\c janus.js can be used directly in any modular\n * JavaScript code base without any previous transformation of the file. That means you can simply\n * do this to access to the Janus API from your modular code.\n \\verbatim\n import { Janus } from 'janus-gateway';\n \\endverbatim\n\n * For more detailed or updated documentation check the\n * <a href=\"https://webpack.js.org/guides/shimming/\">Webpack shimming guide</a> or the equivalent\n * documentation for your bundler of choice.\n */\n\n/*!\\page js-dependencies Working with custom janus.js dependencies\n *\n * Certain dependencies of \\c janus.js may be passed during library initialization as\n * a property list containing the following keys:\n *\n * -# \\c newWebSocket: a function which given WebSockets server and protocol arguments\n * should return a new WebSocket (or something that acts like it)\n * -# \\c webRTCAdapter: an \\c adapter object such as provided by the\n * <a href=\"https://github.com/webrtc/adapter\">webrtc-adapter</a> library\n * -# \\c isArray: a function which tests if a given argument is a JavaScript array\n * -# \\c checkJanusExtension: a function which tests if the Janus Screensharing extension\n * for Chrome is installed/available. This can be done by testing whether or not an element\n * with an \\c id attribute value of \\c janus-extension-installed is present.\n * -# \\c httpAPICall: a function which given an url and options argument performs an\n * HTTP API request to Janus. This function is not as straightforward to implement,\n * see the section on \\ref js-http-apicall below for details.\n *\n * Depending on your needs you do not have to provide all these dependencies, e.g.\n * you do not need to implement the \\c httpAPICall function if your application relies\n * exclusively on WebSockets to access the Janus API.\n *\n * Two implementations of the dependencies object are provided by \\c janus.js:\n *\n * -# \\c Janus.useDefaultDependencies\n * -# \\c Janus.useOldDependencies\n *\n * In turn, each of these implementations accept their dependencies as arguments or fallback on\n * certain global variables. Below follows an overview:\n *\n * \\section js-default-deps Janus.useDefaultDependencies\n * The \\c Janus.useDefaultDependencies method relies on the following native browser APIs:\n *\n * -# \\c Promise: support for \\c Promises as standardised in ES 6 (https://developer.mozilla.org/en-US/docs/Web/JavaScript/Guide/Using_promises)\n * -# \\c fetch: support for the \\c fetch API (https://developer.mozilla.org/en-US/docs/Web/API/Fetch_API)\n * -# \\c WebSocket: support for the \\c WebSocket API (https://developer.mozilla.org/en-US/docs/Web/API/WebSockets_API)\n * -# \\c document.querySelector: support for the \\c document.querySelector API (https://developer.mozilla.org/en-US/docs/Web/API/Document/querySelector)\n *\n * Additionally the \\c adapter object from the <a href=\"https://github.com/webrtc/adapter\">webrtc-adapter</a> library is also required.\n * These dependencies may either be passed explicitly to the function as a property list with keys of the same name, or\n * if omitted the function will fallback to relying on global variables of that name instead.\n *\n * Example:\n\\verbatim\n\tvar customDependencies = Janus.useDefaultDependencies({\n\t\tfetch: myCustomFetchImplementation // myCustomFetchImplementation should provide a compatible fetch() API\n\t});\n\n\tvar relyingOnGlobalsEntirely = Janus.useDefaultDependencies();\n\\endverbatim\n *\n * Being able to passe dependencies like this is especially useful in the context of modern ES modules:\n *\n\\verbatim\nimport adapter from 'webrtc-adapter';\n//  other imports elided\n\nconst setupDeps = () => Janus.useDefaultDependencies({\n\tadapter,\n\t// other dependencies elided\n});\n\nexport const initialiseJanusLibrary = () => Janus.init({dependencies: setupDeps()});\n\\endverbatim\n *\n * \\section js-old-deps Janus.useOldDependencies\n * The \\c Janus.useOldDependencies method relies on:\n *\n * -# \\c jQuery: the JQuery library (http://jquery.com/)\n * -# \\c WebSocket: support for the \\c WebSocket API (https://developer.mozilla.org/en-US/docs/Web/API/WebSockets_API)\n * -# \\c adapter: the \\c adapter object from the <a href=\"https://github.com/webrtc/adapter\">webrtc-adapter</a> library\n *\n * This function provides a simple upgrade path for existing applications which are heavily\n * tied to jQuery (especially since previous versions of \\c janus.js depended on it).\n *\n * \\section js-http-apicall httpAPICall\n * The \\c httpAPICall function is used to issue API calls to the Janus HTTP(S) interfaces.\n * It will be passed two arguments:\n *\n * -# \\c url: a string which refers to the (server) URL of the API endpoint to contact\n * -# \\c options a property list (see below)\n *\n * Any return values from the \\c httpAPICall function will be ignored.\n *\n * When working with HTTP request or response bodies, the \\c httpAPICall is responsible for\n * serialisation to, and deserialisation from the 'wire format' (JSON).\n * That is: the \\c httpAPICall must transform objects to JSON or parse JSON as and when required.\n * Similarly, the \\c httpAPICall is also responsible for setting appropriate HTTP\n * \\c Content-Type (application/json) and/or \\c Accept headers.\n *\n * The \\c options argument may contain the following keys:\n *\n * -# \\c timeout: a timeout in milliseconds which should be imposed on the request.\n *    The \\c httpAPICall implementation is required to implement support for imposing timeouts\n *    on HTTP API requests.\n * -# \\c body: payload to include as body of the outgoing HTTP request.\n      The \\c httpAPICall must encode it in the 'wire format' (JSON).\n * -# \\c withCredentials: a boolean indicating whether or not HTTP credentials should be sent\n * -# \\c success: a callback which should be dispatched when an API request was successful.\n * -# \\c error: a callback which should be dispatched when an API request was unsuccessful, or timed out\n * -# \\c async: a boolean hint which indicates whether or not asynchronous requests are desirable.\n *    This hint is a primarily a remnant for backwards compatible behaviour when working with jQuery.\n *\n * The \\c success callback should be passed the deserialised API response body.\n * The \\c error callback accepts two arguments: a descriptive status text string and the raw error object\n * which caused the \\c error callback to be invoked.\n *\n * \\note The \\c httpAPICall represents the primary way to intercept HTTP(S) API calls issued from within the\n * \\c janus.js library. You can use this mechanism to augment outgoing requests with additional headers\n * or to intercept responses. For example:\n *\n * -# You can support authentication schemes based on the HTTP \\c Authorization header by\n * injecting it into outgoing API requests and routing them through a proxy.\n * -# You can intercept incoming responses and extract data from custom header values generated by a proxy.\n * -# You can combine both to implement a robust defence against <a href=\"https://www.owasp.org/index.php/Cross-Site_Request_Forgery_(CSRF)\">CSRF</a>\n * -# You can reroute the control flow entirely, and e.g. use \\c httpAPICall as an action creator in your\n * <a href=\"http://redux.js.org/\">Redux</a> application.\n *\n * \\section js-extension Custom Screensharing Extension for Chrome\n * To use a different extension for screensharing permissions in Chrome you can pass a \\c extension object\n * to \\c Janus.useDefaultDependencies and \\c Janus.useOldDependencies.\n * The object should provide the following methods:\n *\n * -# \\c init(): Do any setup work here. Will be called once when the dependencies are loaded.\n * -# \\c isInstalled(): should return a boolean indicating whether the Extension was detected and is ready to use.\n * -# \\c getScreen(callback): make a call to the extension to get a \\c streamId here. The streamId can be obtained\n *    from chrome using <a href=\"https://developer.chrome.com/extensions/desktopCapture\">chrome.desktopCapture.chooseDesktopMedia()</a>.\n *    When the request is successful pass the \\c streamId back using <tt>callback(null, streamId)</tt>,\n *    otherwise pass an \\c Error object like \\c callback(error)\n */\n\n/*! \\page rest RESTful, WebSockets, RabbitMQ, MQTT, Nanomsg and UnixSockets API\n *\n * Since version \\c 0.0.6, there are different ways to interact with a\n * Janus instance: a \\ref plainhttp (the default), a \\ref WS, a \\ref rabbit, \\ref apimqtt, \\ref apinanomsg\n * and a \\ref unix (both optional, need an external library to be available). All of\n * the interfaces use the same messages (in terms of requests, responses\n * and notifications), so almost all the concepts described in the\n * \\ref plainhttp section apply to the WebSocket/RabbitMQ/MQTT/Nanomsg/UnixSockets interfaces as well.\n * Besides, since version \\c 0.1.0 the transport mechanism for the Janus API\n * has been made modular, which means other protocols for transporting\n * Janus API messages might become available in the future: considering the\n * Janus protocol is supposed to be mostly agnostic to the protocol it is\n * transported on, the concepts explained in the following sections should\n * apply to those as well.\n *\n * As it will be explained later in the \\ref WS, \\ref rabbit, \\ref apimqtt, \\ref apinanomsg and \\ref unix sections\n * below, the only differences come when addressing specific sessions/handles\n * and in part in how you handle notifications using something different than\n * the REST interface: in fact, since with WebSockets, RabbitMQ, MQTT, Nanomsg and UnixSockets\n * (and, as anticipated, with other protocols that may be added in the future too)\n * there's no REST-based path involved, you'll need a couple of additional\n * identifiers to bridge the gap.\n * Some details are also provided in case you're interested in \\ref auth.\n *\n * \\section plainhttp Plain HTTP REST Interface\n * As anticipated in the \\ref JS documentation, the server deploys a\n * RESTful interface that clients can exploit. The \\c janus.js library\n * makes use of it in a transparent way, but if you're interested in\n * more details about it (e.g., because you want to talk to the server\n * your own way), this page described the interface and the protocol\n * the API exposes and uses.\n *\n * There are basically three types/levels of endpoints you can meet:\n *\n * -# \\ref root (\\c /janus by default, but configurable), which\n * you only \\b POST to in order to create a Janus session;\n * -# \\ref sessions (e.g., \\c /janus/12345678, using the\n * identifier retrieved with a previous create), which you either send\n * a \\b GET to (long poll for events and messages from plugins) or a \\b POST\n * (to create plugin handles or manipulate the session);\n * -# \\ref handles (e.g., \\c /janus/12345678/98765432, appending\n * the handle identifier to the session one) which you only send \\b POST\n * messages to (messages/negotiations for a plugin, handle manipulation),\n * as all events related to this handle would be received in the session\n * endpoint \\b GET (the \\c janus.js library would redirect the incoming\n * messages to the right handle internally).\n *\n * Messages and requests you can send to and receive from any of the\n * above mentioned endpoints are described in the following chapters.\n * In general, all messages share at least two fields:\n *\n * - \\c janus: the request/event (e.g., \"create\", \"attach\", \"message\", etc.);\n * - \\c transaction: a random string that the client can use to match incoming\n * messages from the server (since, as explained in the \\ref plugins\n * documentation, all messages are asynchronous).\n *\n * Different messages will of course add different information to this\n * base syntax. Error message, instead, usually have these fields:\n *\n * - \\c janus: this would be \"error\";\n * - \\c transaction: this would be the transaction identifier of the request\n * that failed;\n * - \\c error: a JSON object containing two fields:\n *   - \\c code: a numeric error code, as defined in apierror.h;\n *   - \\c reason: a verbose string describing the cause of the failure.\n *\n * An example of an error is presented here:\n *\n\\verbatim\n{\n\t\"janus\" : \"error\",\n\t\"transaction\" : \"a1b2c3d4\"\n\t\"error\" : {\n\t\t\"code\" : 458\n\t\t\"reason\" : \"Could not find session 12345678\"\n\t}\n}\n\\endverbatim\n *\n *\n * \\section info Getting info about the Janus instance\n * The API exposes an \\c info endpoint you can query to get information\n * about the Janus instance you're talking to.

Specifically, the new endpoint is constructed by\n * concatenating the server root and the session identifier you've been\n * returned (\\c e.g., \\c /janus/12345678).\n *\n * This endpoint can be used in two different ways:\n *\n * -# using a parameter-less \\b GET request to the endpoint, you'll\n * issue a long-poll request to be notified about events and incoming\n * messages from this session;\n * -# using a \\b POST request to send JSON messages, you'll interact\n * with the session itself.\n *\n * <hr>\n *\n * \\par Long-poll requests\n * The long-poll will only trigger events related to messages you're\n * being sent from plugins, and as such will be clearer to understand\n * once you read the \\ref handles section. That said, the events are formatted\n * this way:\n *\n * - \\c janus: this would be \"event\";\n * - \\c sender: this would be the unique numeric plugin handle identifier;\n * - \\c transaction: this is optional: it is either related to a request\n * you sent to a plugin before, or it may be missing in case this is an\n * event the plugin sent on its own account;\n * - \\c plugindata: a JSON object containing the info coming from the plugin itself:\n *   - \\c plugin: the plugin's unique package name (e.g., \\c janus.plugin.echotest);\n *   - \\c data: an opaque JSON object that is plugin specific.\n * - \\c jsep: an optional JSON object containing the JSEP SDP (offer or\n * answer) the plugin may send to negotiate a WebRTC PeerConnection with\n * the client (check the \\ref handles section for more details).\n *\n * An example of such an event (in this case, sent by the janus_echotest.c\n * plugin in response to a request) is presented here:\n *\n\\verbatim\n{\n\t\"janus\" : \"event\",\n\t\"sender\" : 1815153248,\n\t\"transaction\" : \"sBJNyUhH6Vc6\",\n\t\"plugindata\" : {\n\t\t\"plugin\": \"janus.plugin.echotest\",\n\t\t\"data\" : {\n\t\t\t\"echotest\" : \"event\",\n\t\t\t\"result\" : \"ok\"\n\t\t}\n\t}\n}\n\\endverbatim\n *\n * The long-poll request has a 30 seconds timeout. If it has no event to\n * report, a simple \\em keep-alive message will be triggered:\n *\n\\verbatim\n{\n\t\"janus\" : \"keepalive\",\n}\n\\endverbatim\n *\n * As with all long-poll based approaches, it's up to your application\n * to send a new polling request as soon as an event or a keep-alive\n * has been received.\n *\n * Notice that, by default, the long poll returns a single event: that is,\n * as soon as a message becomes available in the session queue, that event\n * is returned and the long poll closes. If you want to receive more events\n * within the context of the same long poll, you can pass the \\c maxev\n * query string parameter to the GET, e.g.:\n *\n\\verbatim\nGET http://host:port/janus/<sessionid>?maxev=5\n\\endverbatim\n *\n\\verbatim\n[\n\t{\n\t\t// Event #1\n\t\t\"janus\" : \"event\",\n\t\t[..]\n\t},\n\t{\n\t\t// Event #2\n\t\t\"janus\" : \"event\",\n\t\t[..]\n\t},\n\t[..]\n]\n\\endverbatim\n *\n * This request will instruct the server to return at maximum 5 events\n * within the context of the same long poll, formatted as a JSON array\n * of events. Please beware that this does \\b NOT mean that you'll\n * always get 5 events this way: it only means that, if a message becomes\n * available in the queue and more events are present as well, Janus will\n * return more than one without needing you to send multiple long polls\n * immediately thereafter to get them. For this reason, don't be surprised\n * if even with a \\c maxev parameter set, you'll still get a single\n * event being notified as the sole object in the returned array.\n *\n * <hr>\n *\n * \\par Interacting with the session\n * To interact with the session, e.g., to create a new handle to attach\n * to a plugin or destroy the current session, you need to send a \\b POST\n * JSON message to the session endpoint.\n *\n * To attach to a plugin in order to exploit its features, you need to\n * \\b POST a \\c janus \"attach\" JSON message to the server; you'll need\n * of course to provide information on the plugin you want to attach to,\n * which can be done using the \\c plugin field:\n *\n\\verbatim\n{\n\t\"janus\" : \"attach\",\n\t\"plugin\" : \"<the plugin's unique package name>\",\n\t\"transaction\" : \"<random string>\"\n}\n\\endverbatim\n *\n * Notice that you can also provide an optional \\c opaque_id string\n * identifier (for more details on why this might be useful, read more\n * <a href=\"https://github.com/meetecho/janus-gateway/pull/748\">here</a>).\n * If the request is successful, you'll receive the unique plugin handle\n * identifier in a response formatted the same way as the session create\n * one, that is like this:\n *\n\\verbatim\n{\n\t\"janus\" : \"success\",\n\t\"transaction\" : \"<same as the request>\",\n\t\"data\" : {\n\t\t\"id\" : <unique integer plugin handle ID>\n\t}\n}\n\\endverbatim\n *\n * In case of an error, you'll receive an error message as the one introduced\n * before. This request, if issued with a POST to a valid session endpoint, can only\n * fail if you miss any of the required fields in the request or if the\n * plugin you requested is not available in the server.\n *\n * To destroy the current session, instead, just send a \"destroy\" \\c janus\n * request:\n *\n\\verbatim\n{\n\t\"janus\" : \"destroy\",\n\t\"transaction\" : \"<random string>\"\n}\n\\endverbatim\n *\n * This will also destroy the endpoint created for this session.\n * If your session is currently managing one or more plugin handles,\n * make sure you destroy them first (as explained in the next section).\n * The server tries to do this automatically when receiving a session\n * destroy request, but a cleaner approach on the client side would help\n * nonetheless avoid potential issues.\n *\n * Notice that a session may also be destroyed automatically in case of\n * inactivity. If Janus doesn't receive any activity (requests, long polls)\n * for a session for a time longer than the \\c session_timeout value\n * configured in \\c janus.jcfg then the session will timeout, and a\n * \\c timeout event will be fired. If a \\c reclaim_session_timeout value\n * is configured, you can still reclaim the session from the same or\n * a different transport using the \\c claim request, within a limited\n * amount of time. An unreclaimed session that has timed out will be\n * permanently destroyed, and will destroy all its handles as well.\n *\n * \\section handles The plugin handle endpoint\n * Once you've created a plugin handle, a new endpoint you can use is created\n * in the server. Specifically, the new endpoint is constructed by\n * concatenating the server root, the session identifier and the new\n * plugin handle identifier you've been returned (\\c e.g.,\n * \\c /janus/12345678/98765432).\n *\n * You can use this plugin handle for everything that is related to the\n * communication with a plugin, that is, send the plugin a message,\n * negotiate a WebRTC connection to attach to the plugin, and so on.\n *\n * To send a plugin a message/request, you need to \\b POST the handle\n * endpoint a \\c janus \"message\" JSON payload. The \\c body field will\n * have to contain a plugin-specific JSON payload. In case the message\n * also needs to convey WebRTC-related negotiation information, a \\c jsep\n * field containing the JSON-ified version of the JSEP object can be\n * attached as well.\n *\n * \\note If you attach a \\c jsep object, whether it's an offer or an answer,\n * you're stating your will to negotiate a PeerConnection. This means that\n * an empty or invalid \\c jsep object will trigger a validation and will\n * cause the whole request to fail, so make sure you exclude the field\n * completely from your request if all you're interested into is sending\n * a message to a plugin.\n *\n * Here's an example of a message you may send the janus_echotest.c plugin\n * to mute your audio:\n *\n\\verbatim\n{\n\t\"janus\" : \"message\",\n\t\"transaction\" : \"sBJNyUhH6Vc6\",\n\t\"body\" : {\n\t\t\"audio\" : false\n\t}\n}\n\\endverbatim\n *\n * The same message containing negotiation information as well, instead,\n * (an OFFER, in this example), is presented here:\n *\n\\verbatim\n{\n\t\"janus\" : \"message\",\n\t\"transaction\" : \"sBJNyUhH6Vc6\",\n\t\"body\" : {\n\t\t\"audio\" : false\n\t},\n\t\"jsep\" : {\n\t\t\"type\" : \"offer\",\n\t\t\"sdp\" : \"v=0\\r\\no=[..more sdp stuff..]\"\n\t}\n}\n\\endverbatim\n *\n * Please notice that, if for any reason you don't want to use the\n * trickling of ICE candidates from your application (which means you'll\n * include them all in the SDP OFFER or ANSWER, which is usually not\n * recommended), you'll have to add an additional <code>\"trickle\" : false</code>\n * attribute to the \"jsep\" object, to explicitly tell Janus you won't\n * send any \\c trickle candidate (by default Janus will always assume\n * support for trickle).\n *\n * If you're going to \\c trickle candidates, instead, there is an ad-hoc\n * message you can use to do so which is called, unsurprisingly, \\c trickle\n * and which you can use to send one or more trickle candidates to Janus.\n * Since such a message is related to a specific PeerConnection, it will\n * need to be addressed to the right Handle just as the \\c message introduced\n * previously. A \\c trickle message can contain three different kind of\n * information:\n *\n *  - a single trickle candidate;\n *  - an array of trickle candidates;\n *  - a null candidate or a \\c completed JSON object to notify the end of the\n * candidates.\n *\n * This is an example of a single candidate being trickled:\n *\n\\verbatim\n{\n\t\"janus\" : \"trickle\",\n\t\"transaction\" : \"hehe83hd8dw12e\",\n\t\"candidate\" : {\n\t\t\"sdpMid\" : \"video\",\n\t\t\"sdpMLineIndex\" : 1,\n\t\t\"candidate\" : \"...\"\n\t}\n}\n\\endverbatim\n *\n * This, instead, is an example of how to group more trickle candidates\n * in a single request (particularly useful if you're wrapping Janus in\n * your server and want to reduce the number of transactions):\n *\n\\verbatim\n{\n\t\"janus\" : \"trickle\",\n\t\"transaction\" : \"hehe83hd8dw12e\",\n\t\"candidates\" : [\n\t\t{\n\t\t\t\"sdpMid\" : \"video\",\n\t\t\t\"sdpMLineIndex\" : 1,\n\t\t\t\"candidate\" : \"...\"\n\t\t},\n\t\t{\n\t\t\t\"sdpMid\" : \"video\",\n\t\t\t\"sdpMLineIndex\" : 1,\n\t\t\t\"candidate\" : \"...\"\n\t\t},\n\t\t[..]\n\t]\n}\n\\endverbatim\n *\n * Finally, this is how you can tell Janus that you sent all the trickle\n * candidates that were gathered:\n *\n\\verbatim\n{\n\t\"janus\" : \"trickle\",\n\t\"transaction\" : \"hehe83hd8dw12e\",\n\t\"candidate\" : {\n\t\t\"completed\" : true\n\t}\n}\n\\endverbatim\n *\n * Plugins may handle this requests synchronously or asynchronously. In\n * the former, plugins would return a response to the request itself\n * immediately; in the latter, instead, the plugin would only notify a\n * successful reception of the request, which it would process later.\n * Considering the asynchronous nature of the Janus API, a successful\n * management of such messages within Janus would in such case result in\n * a \\c janus \"ack\" messages being sent back to the client. A logical response\n * to those messages, if needed, would be provided as an event in the\n * long-poll interface described previously, and clients would be able\n * to match it to the original request by means of the transaction\n * identifiers. It is worth noting, though, that should a WebRTC negotiation\n * be involved you don't have to expect an ANSWER to your OFFER to be\n * sent back in the same transaction. A plugin may decide, in its\n * application logic, to not provide you with an ANSWER right away, but\n * only after some internal state changes occur. It's up to your application\n * to handle the negotiation state accordingly.\n *\n * An example of an \"ack\" being sent back to the client, using the previous\n * sample request as a reference, is presented here:\n *\n\\verbatim\n{\n\t\"janus\" : \"ack\",\n\t\"transaction\" : \"sBJNyUhH6Vc6\"\n}\n\\endverbatim\n *\n * If you receive this ack instead of a \"success\" response, you can be\n * sure the plugin has received the message, and is going to process it soon.\n *\n * In case of an error, instead, you'll receive an error message as the one\n * introduced before. This request, if issued with a POST to a valid plugin\n * handle endpoint, can only fail if you miss any of the required fields\n * in the request, if the plugin you tried to contact is not available in\n * the server anymore, if an error occurred in the plugin when trying to\n * receive the message or if the \\c jsep SDP you may have provided is\n * invalid.\n *\n * To destroy the plugin handle, instead, just send a \"detach\" \\c janus\n * request:\n *\n\\verbatim\n{\n\t\"janus\" : \"detach\",\n\t\"transaction\" : \"<random string>\"\n}\n\\endverbatim\n *\n * This will also destroy the endpoint created for this plugin handle.\n * If your plugin handle is also managing an ongoing WebRTC connection\n * with the plugin, make sure it is torn down as part of this process.\n * The plugin implementation and the Janus core should do this\n * automatically, but implementing the right behaviour in clients would\n * help avoid potential issues nonetheless. Notice that you may receive\n * \\c detached event after a handle has been detached, whether this was\n * done in response to a request or automatically, in response to an event.\n *\n * If you're interested in keeping the handle alive but want to hang up\n * the associated PeerConnection, if available, just send a \"hangup\" \\c janus\n * request:\n *\n\\verbatim\n{\n\t\"janus\" : \"hangup\",\n\t\"transaction\" : \"<random string>\"\n}\n\\endverbatim\n *\n * This is usually not required, as you can typically just hangup your\n * WebRTC PeerConnection normally and Janus will figure out it's gone\n * by itself. Anyway, there are cases where this might be useful (e.g.,\n * the connection was stuck in some weird ICE/DTLS state) as it can be\n * used to reset the connection state for the handle.\n *\n * \\section events WebRTC-related events\n *\n * As anticipated in the previous sections, Janus can send events and\n * notifications at any time through the long poll channel (or, as it\n * will be explained later, through the related push mechanisms made\n * available by other transport protocols ). While this channel is\n * mostly used to convey asynchronous notifications originated by\n * plugins as part of the messaging they may have with the application\n * using it, the same channel is actually used by Janus to trigger\n * events related to different aspects pertaining a specific handle.\n *\n * In particular, for each handle involving a PeerConnection Janus\n * provides notifications about its current state. To do so, the\n * following events may be received as well:\n *\n *  - \\c webrtcup: ICE and DTLS succeeded, and so Janus correctly\n * established a PeerConnection with the user/application;\n *  - \\c media: whether Janus is receiving (\\c receiving: \\c true/false)\n * audio/video (\\c type: \\c \"audio/video\") on this PeerConnection;\n *  - \\c slowlink: whether Janus is reporting trouble sending/receiving\n * (\\c uplink: \\c true/false) media on this PeerConnection;\n *  - \\c hangup: the PeerConnection was closed, either by Janus or by\n * the user/application, and as such cannot be used anymore.\n *\n * As such, to monitor the status of a PeerConnection as seen from\n * Janus you can make use of these events to track what's going on. A\n * correct flow for an active PeerConnection would be one that, after a\n * WebRTC negotiation and setup, results in a \\c webrtcup event followed\n * by two \\c media events (in case both audio and video have been\n * negotiated) specifying that the first audio/video packets have been\n * received. A \\c hangup event would inform the user/application that\n * no media is being exchanged with Janus anymore.\n *\n * Here are a few examples of how these events may look like.\n *\n * A PeerConnection becoming ready:\n *\n\\verbatim\n{\n\t\"janus\" : \"webrtcup\",\n\tsession_id: <the session identifier>,\n\tsender: <the handle identifier>\n}\n\\endverbatim\n *\n * First audio bytes being received by Janus:\n *\n\\verbatim\n{\n\t\"janus\" : \"media\",\n\tsession_id: <the session identifier>,\n\tsender: <the handle identifier>,\n\t\"type\" : \"audio\",\n\t\"receiving\" : true\n}\n\\endverbatim\n *\n * Audio not getting to Janus anymore for some reason:\n *\n\\verbatim\n{\n\t\"janus\" : \"media\",\n\t\"session_id\" : <the session identifier>,\n\t\"sender\" : <the handle identifier>\n\t\"type\" : \"audio\",\n\t\"receiving\" : false\n}\n\\endverbatim\n *\n * Audio getting to Janus again (same message as first audio):\n *\n\\verbatim\n{\n\t\"janus\" : \"media\",\n\t\"session_id\" : <the session identifier>,\n\t\"sender\" : <the handle identifier>\n\t\"type\" : \"audio\",\n\t\"receiving\" : true\n}\n\\endverbatim\n *\n * Janus reporting problems sending media to a user (user sent many NACKs\n * in the last second; uplink=true is from Janus' perspective):\n *\n\\verbatim\n{\n\t\"janus\" : \"slowlink\",\n\t\"session_id\" : <the session identifier>,\n\t\"sender\" : <the handle identifier>\n\t\"uplink\" : true,\n\t\"lost\" : <number of lost packets in the last second>\n}\n\\endverbatim\n *\n * PeerConnection closed for a DTLS alert (normal shutdown):\n *\n\\verbatim\n{\n\t\"janus\" : \"hangup\",\n\t\"session_id\" : <the session identifier>,\n\t\"sender\" : <the handle identifier>,\n\t\"reason\" : \"DTLS alert\"\n}\n\\endverbatim\n *\n * It is important to point out that the \\c media event notifications\n * only apply if your PeerConnection is going to actually send media to\n * Janus. A \\c recvonly PeerConnection, for instance (e.g., as the\n * Streaming plugin would create) would never trigger any \\c media\n * event, as Janus would never be receiving media, but only send it.\n *\n * \\section WS WebSockets Interface\n * WebSockets provide a more efficient means for implementing a bidirectional communication.\n * This is especially useful if you're wrapping the Janus API on your\n * servers, as it allows you to avoid all the noise and overhead introduced\n * by several concurrent HTTP transactions and long polls by relying on\n * what may be seen as a single \"control channel\".\n *\n * To interact with Janus using WebSockets you MUST specify a specific\n * subprotocol, named \\c janus-protocol, e.g.,\n *\n\\verbatim\nvar websocket = new WebSocket('ws://1.2.3.4:8188', 'janus-protocol');\n\\endverbatim\n *\n * The \\c janus.js library does this automatically.\n *\n * As anticipated at the beginning of this section, the actual messages\n * being exchanged are exactly the same. This means that all the concepts\n * introduced before still apply: you still create a session, attach to\n * a plugin and interact with it exactly the same way. What is different\n * is, of course, the REST path approach that becomes unavailable when\n * using a WebSocket as a control channel. To address the idenfitiers\n * that become missing using WebSockets, you'll need to add additional\n * fields to the requests when necessary.\n *\n * So, when you want to create a session using the REST API, you send a\n * POST to the server base path:\n *\n\\verbatim\n{\n\t\"janus\" : \"create\",\n\t\"transaction\" : \"<random alphanumeric string>\"\n}\n\\endverbatim\n *\n * The same applies if you're interested in getting generic info from the\n * Janus instance. Since there's no \\b GET you can use, a specific \\c janus\n * request type called \\c info is available:\n *\n\\verbatim\n{\n\t\"janus\" : \"info\",\n\t\"transaction\" : \"<random alphanumeric string>\"\n}\n\\endverbatim\n *\n * Since you'd contact the base path for both requests, you don't need to add any identifier\n * for this scenario. But if instead you want to attach to a plugin within\n * the context of a specific session, using the REST API you'd send a\n * post to the \\c /janus/<session-id> endpoint:\n *\n\\verbatim\n{\n\t\"janus\" : \"attach\",\n\t\"plugin\" : \"<the plugin's unique package name>\",\n\t\"transaction\" : \"<random string>\"\n}\n\\endverbatim\n *\n * To make this work with WebSockets as well, you need to add a further\n * field called \\c session_id in the request:\n *\n\\verbatim\n{\n\t\"janus\" : \"attach\",\n\t\"session_id\" : <the session identifier>,\t\t// NEW!\n\t\"plugin\" : \"<the plugin's unique package name>\",\n\t\"transaction\" : \"<random string>\"\n}\n\\endverbatim\n *\n * which will allow the WebSocket server to understand which session this\n * request pertains to. At the same time, when you need to address a\n * specific handle (e.g., to send a message to a plugin, or negotiate a\n * WebRTC PeerConnection) you'll need to add a \\c handle_id field to the\n * request as well, or the request will be rejected:\n *\n\\verbatim\n{\n\t\"janus\" : \"message\",\n\t\"session_id\" : <the session identifier>,\t\t// NEW!\n\t\"handle_id\" : <the handle identifier>,\t\t// NEW!\n\t\"transaction\" : \"sBJNyUhH6Vc6\",\n\t\"body\" : {\n\t\t\"audio\" : false\n\t}\n}\n\\endverbatim\n *\n * Considering the bidirectional nature of WebSockets and the fact that\n * the channel will be shared for different requests, you'll need to pay\n * extra attention to the \\c transaction identifier, which will allow you\n * to map incoming responses and events to the request you sent that\n * originated them.\n *\n * An \\b important aspect to point out is related to keep-alive messages\n * for WebSockets Janus channels. As explained above, a Janus session is\n * kept alive as long as there's no inactivity for \\c session_timeout seconds:\n * if no messages have been received in that time frame, the session is\n * marked as timed-out and, unless reclaimed, will be torn down by the server.\n * A normal activity on a session is usually enough to prevent that;\n * for a more prolonged inactivity with respect to messaging, on plain\n * HTTP the session is usually kept alive through the regular long poll\n * requests, which act as activity as long as the session is concerned.\n * This aid is obviously not possible when using WebSockets, where a single channel is\n * used both for sending requests and receiving events and responses. For\n * this reason, an ad-hoc message for keeping alive a Janus session should\n * to be triggered on a regular basis:\n *\n\\verbatim\n{\n\t\"janus\" : \"keepalive\",\n\t\"session_id\" : <the session identifier>,\n\t\"transaction\" : \"sBJNyUhH6Vc6\"\n}\n\\endverbatim\n *\n * This will make sure that the server detects activity on the session\n * even when no actual messages are being exchanged with handles.\n *\n * As a last point, another slight difference with WebSockets comes from\n * how push notifications are implemented. In the \\ref plainhttp this is\n * done via long polls: that is, you explicitly subscribe to notifications,\n * and have to do that again as soon as an event has been received. With\n * WebSockets, this is not needed: as soon as you create a session on a\n * WebSocket, that channel becomes automatically subscribed for events\n * related to that sessions, and you'll receive them on the same WebSocket.\n * For the same reason, as soon as the WebSocket is closed, all the sessions\n * created within its context are considered closed as well, and so their\n * resources (including all the handles and PeerConnections) will be\n * released as well.\n *\n * \\note The same \\c janus.js JavaScript library can be used both with the\n * REST and the WebSockets API: all you need to do is provide the right\n * Janus server address during the initialization and the library will\n * use one or the other according to the protocol prefix.\n *\n * \\section rabbit RabbitMQ interface\n * The semantics of how the requests have to be built, when compared to\n * the usage of plain HTTP, is exactly the same as for WebSockets, so\n * refer to the \\ref WS documentation for details about that.\n *\n * Of course, there are other aspects that differ when making use of\n * RabbitMQ messaging to talk to Janus, rather than using HTTP messages\n * or WebSockets. Specifically, RabbitMQ just basically forwards messages\n * on queues, and as such implementing a pseudo-bidirectional channel\n * as the Janus API requires some precaution.\n *\n * In particular, when configuring Janus to use RabbitMQ you'll have to\n * specify \\b two \\b queues:\n *\n * - a queue for \\b incoming messages (application -> Janus);\n * - a queue for \\b outgoing messages (Janus -> application).\n *\n * The proper usage of these queues will allow you to implement the kind\n * of bidirectional channel Janus needs.\n *\n * Another aspect to point out is that Janus requires all requests to\n * have a random \\c correlation_id identifier. In fact, as pointed out\n * in the previous sections, the Janus API is conceived as a request/response\n * protocol that can involve asynchronous notifications as well. In order\n * to make sure that an application can match a received response to one\n * of the requests made earlier, Janus copies the \\c correlation_id\n * identifier from the original request in the response to it: this is\n * compliant with the\n * <a href=\"https://www.rabbitmq.com/tutorials/tutorial-six-python.html\">RPC pattern</a>\n * as specified in the RabbitMQ documentation. Notifications originated by\n * Janus, instead, will not include a \\c correlation_id identifier, and as\n * such applications shouldn't expect any: applications will still be able\n * to match a notification to a request, if the involved plugin was\n * implemented to do so, by looking at the Janus-level \\c transaction\n * identifier.\n *\n * \\section apimqtt MQTT interface\n * The semantics of how the requests have to be built, when compared to\n * the usage of plain HTTP, is exactly the same as for WebSockets, so\n * refer to the \\ref WS documentation for details about that.\n *\n * Of course, there are other aspects that differ when making use of\n * MQTT messaging to talk to Janus, rather than using HTTP messages\n * or WebSockets. Similar to RabbitMQ, MQTT just basically forwards messages\n * on queues, and as such implementing a pseudo-bidirectional channel\n * as the Janus API requires some precaution.\n *\n * In particular, when configuring Janus to use MQTT you'll have to\n * specify \\b two \\b queues:\n *\n * - a queue for \\b incoming messages (application -> Janus);\n * - a queue for \\b outgoing messages (Janus -> application).\n *\n * The proper usage of these queues will allow you to implement the kind\n * of bidirectional channel Janus needs.\n *\n * \\section apinanomsg Nanomsg interface\n * The semantics of how the requests have to be built, when compared to\n * the usage of plain HTTP, is exactly the same as for WebSockets, RabbitMQ\n * and MQTT, so refer to the \\ref WS documentation for details about that.\n *\n * Apart from that, the only configuration needed is related to the Nanomsg\n * address to use, and whether it should be used to bind locally or to\n * connect to a remote endpoint. Notice that only the \\c NN_PAIR pattern\n * is supported by the plugin, so no Pub/Sub or other variations.\n *\n * \\section unix UnixSockets interface\n * The semantics of how the requests have to be built, when compared to\n * the usage of plain HTTP, is exactly the same as for WebSockets, RabbitMQ\n * MQTT and Nanomsg, so refer to the \\ref WS documentation for details about that.\n *\n * Apart from that, the only configuration needed is related to the path\n * the client and server will be sharing, and the socket type. Notice that only the\n * \\c SOCK_SEQPACKET and \\c SOCK_DGRAM types are supported in the plugin.\n *\n */\n\n/*! \\page auth Authenticating the Janus API\n * By default no authentication is involved when using the Janus API.\n * This means that the API is completely open, and that everybody can\n * talk to Janus and its plugins and set up media connections. There are\n * times, though, where limiting access to Janus may be desirable, e.g.,\n * when you want to prevent unauthorized users to join a service you\n * created, or when you wrap the Janus API in your server and you want\n * your application to be the only one to be able to interact with\n * Janus from a messaging perspective.\n *\n * There are a couple of ways to authenticate requests in Janus:\n *\n * - using a \\ref token (useful for web users);\n * - using a \\ref signed (useful for web users);\n * - using a \\ref secret (useful when wrapping the Janus API).\n *\n * \\section token Stored token based authentication mechanism\n * The token based authentication mechanism expects all users to provide,\n * in each request, a \\c token string attribute: if this token is\n * known to Janus, the request will be accepted, otherwise it will be\n * rejected as an \\c unauthorized response. Configuring the token based\n * authentication mechanism is easy enough: you can do that either via\n * the command line (\\c -A or \\c --token-auth ) or in the \\c janus.jcfg\n * configuration (\\c token_auth value in the \\c general section).\n *\n * These tokens are completely opaque to Janus, meaning they can be\n * pretty much anything that you want. Janus does not do any form of\n * authorization/authentication itself: it's up to you to provide it\n * with valid tokens users can use, e.g., as part of your server-side\n * application handling users. You can add and remove tokens\n * dynamically using the \\ref admin, which means you will need to enable\n * it if you want to use tokens, or otherwise all requests will fail\n * (Janus will never have a valid token, so all requests will be rejected).\n *\n * You add tokens using the \\c add_token admin request, while you\n * remove them using \\c remove_token. You can also limit the scope of tokens\n * to specific plugins, by passing a list of plugins to \\c add_token or\n * modifying the token properties via \\c allow_token and \\c disallow_token.\n * By default (\\c add_token without any plugin specified) Janus assumes\n * a new token is allowed to access all plugins. A list of all the\n * existing tokens can be retrieved with a \\c list_tokens request.\n *\n * Here are a couple of examples of how you can use the requests:\n *\n\\verbatim\n{\n\t\"janus\" : \"add_token\",\n\t\"token\": \"a1b2c3d4\",\n\t\"transaction\" : \"sBJNyUhH6Vc6\",\n\t\"admin_secret\": \"adminpassword\"\n}\n\\endverbatim\n *\n * This adds a new token (a1b2c3d4) that is allowed to access all the\n * plugins in Janus (no limitation provided in \\c add_token ). To create\n * a new token and limit the scope to a few selected plugins, you can\n * use this other syntax instead (notice the extra \\c plugins array):\n *\n\\verbatim\n{\n\t\"janus\" : \"add_token\",\n\t\"token\": \"a1b2c3d4\",\n\t\"plugins\": [\n\t\t\"janus.plugin.streaming\",\n\t\t\"janus.plugin.videoroom\"\n\t],\n\t\"transaction\" : \"sBJNyUhH6Vc6\",\n\t\"admin_secret\": \"adminpassword\"\n}\n\\endverbatim\n *\n * In this other example, we're creating a new token, and also telling\n * Janus that the only plugins a user with this token can access are\n * the Streaming and Videoroom plugins. An attempt to attach to a\n * different plugin (e.g., EchoTest) will result in an error.\n *\n * You can change the permissions a token has with respect to plugin\n * access at any time. In the following example, we add a new plugin\n * to the permissions for an existing token:\n *\n\\verbatim\n{\n\t\"janus\" : \"allow_token\",\n\t\"token\": \"a1b2c3d4\",\n\t\"plugins\": [\n\t\t\"janus.plugin.echotest\"\n\t],\n\t\"transaction\" : \"sBJNyUhH6Vc6\",\n\t\"admin_secret\": \"adminpassword\"\n}\n\\endverbatim\n *\n * This way, the provided token is now also allowed to access the EchoTest\n * plugin. To remove a permission, the syntax is this one instead:\n *\n\\verbatim\n{\n\t\"janus\" : \"disallow_token\",\n\t\"token\": \"a1b2c3d4\",\n\t\"plugins\": [\n\t\t\"janus.plugin.videoroom\"\n\t],\n\t\"transaction\" : \"sBJNyUhH6Vc6\",\n\t\"admin_secret\": \"adminpassword\"\n}\n\\endverbatim\n *\n * To retrieve a list of all the valid tokens Janus is aware of, together\n * with the plugins each of them is allowed to access, a \\c list_tokens\n * request can be used:\n *\n\\verbatim\n{\n\t\"janus\" : \"list_tokens\",\n\t\"transaction\" : \"sBJNyUhH6Vc6\",\n\t\"admin_secret\": \"adminpassword\"\n}\n\\endverbatim\n *\n * Finally, you can get rid of a token using a \\c remove_token request:\n *\n\\verbatim\n{\n\t\"janus\" : \"remove_token\",\n\t\"token\": \"a1b2c3d4\",\n\t\"transaction\" : \"sBJNyUhH6Vc6\",\n\t\"admin_secret\": \"adminpassword\"\n}\n\\endverbatim\n *\n * As anticipated, with the token based mechanism enabled, all users\n * will need to provide a valid token as part of their requests. This is\n * done by adding a \\c token attribute to the request root, e.g.:\n *\n\\verbatim\n{\n\t\"janus\" : \"create\",\n\t\"transaction\" : \"sBJNyUhH6Vc6\",\n\t\"token\": \"usertoken\"\n}\n\\endverbatim\n *\n * The same applies for the long poll GET messages as well, which will\n * need to contain the \\c token as a query string parameter.\n *\n * A valid token will mean the request will be accepted and processed\n * normally. A missing or invalid token, instead, will result in an\n * error being returned:\n *\n\\verbatim\n{\n\t\"janus\" : \"error\",\n\t\"transaction\" : \"sBJNyUhH6Vc6\",\n\t\"error\" : {\n\t\t\"code\" : 403,\n\t\t\"reason\" : \"Unauthorized request (wrong or missing secret/token)\"\n\t}\n}\n\\endverbatim\n *\n * An attempt to use a valid token to attach to a plugin it is not\n * allowed to access, instead, will result in a different error:\n *\n\\verbatim\n{\n\t\"janus\" : \"error\",\n\t\"transaction\" : \"sBJNyUhH6Vc6\",\n\t\"error\" : {\n\t\t\"code\" : 405,\n\t\t\"reason\" : \"Provided token can't access plugin 'janus.plugin.echotest'\"\n\t}\n}\n\\endverbatim\n *\n * \\section signed HMAC-Signed token authentication\n *\n * <div class=\"well\"><b>NOTE WELL:</b> At the time of writing, HMAC-Signed\n * tokens are ONLY available for the VideoRoom plugin. If you need authentication\n * for other plugins, you should use the \\ref token instead.</div>\n *\n * Simple token based authentication requires the application host to\n * continuously update the Janus instance on permission changes.\n * Since Janus stores the tokens in memory, it can be problematic to guarantee\n * the permissions of a dynamic application stay in sync with Janus.\n *\n * This problem can be solved by using a type of nonce / lease system to\n * let the application server generate automatically expiring tokens without\n * requiring direct communication with or any data storage in Janus.\n *\n * You can use the HMAC signed token mechanism by enabling token authentication\n * in general, as above (\\c -A or \\c --token-auth) and specifying an encryption\n * secret using \\c --token-auth-secret. The same can be accomplished using\n * \\c token_auth and \\c token_auth_secret in the \\c general section of\n * \\c janus.jcfg.\n *\n * With Signed token support enabled, dynamic token creation via the \\ref admin\n * is not supported. Instead, Janus will look for tokens with a format like:\n *\n\\verbatim\n<timestamp>,janus,<plugin1>[,plugin2...]:<signature>\n\\endverbatim\n *\n * Where \\c timestamp is a UNIX timestamp (seconds since 0:00 UTC, 1.1.1970)\n * that marks the point in time at which the token expires;\n * \\c plugin1 etc. are the \\c bundle names of plugins (such as \\c janus.plugin.videoroom);\n * and \\c signature is the base64-encoded HMAC-SHA1 signature of the expiry\n * timestamp in ASCII format, hashed using the \\c --token-auth-secret as a key.\n *\n * The following function can be used to sign tokens using the node.js crypto library:\n *\n\\verbatim\nconst crypto = require('crypto');\nfunction getJanusToken(realm, data = [], timeout = 24 * 60 * 60) {\n  const expiry = Math.floor(Date.now() / 1000) + timeout;\n\n  const strdata = [expiry.toString(), realm, ...data].join(',');\n  const hmac = crypto.createHmac('sha1', secret);\n  hmac.setEncoding('base64');\n  hmac.write(strdata);\n  hmac.end();\n\n  return [strdata, hmac.read()].join(':');\n};\n\nconst token = getJanusToken('janus', ['janus.plugin.videoroom']);\n\\endverbatim\n *\n * The \\c janus parameter here is the \\c realm of the token. For authenticating the\n * Janus API it should always be set to \\c janus.\n *\n * When Janus encounters a token, it will:\n *\n * - verify that the timestamp has not passed\n * - verify that the signature matches the timestamp\n * - if the request requires access to a plugin, verify that the signature allows access\n *\n * Since the auth secret should never leave the application side, a signature\n * like this can only be generated by the application server, which needs to\n * be configured using the same secret.\n *\n * Please note that tokens of this sort cannot be revoked after being signed\n * and passed to the client. Instead of signing tokens with late expirys,\n * it is recommended to use tokens with shorter durations and generate and\n * transition to a new token within the expiry time of every last token when\n * the lease time is unknown and security is critical.\n *\n * \\section secret Shared static secret\n * Several deployers showed an interest in wrapping the Janus API on\n * their server side: this allows them to keep the interaction with their\n * users the way it was before, while still benefiting from the features\n * Janus provides. This is an easy enough step, as it just needs developers\n * to relay the involved SDP, and implementing the Janus API messages to\n * handle the logic.\n *\n * That said, since in this case Janus would be contacted, through the API,\n * just by a limited number of applications (e.g., application servers\n * made in node.js, Ruby, Java Servlets or whatever) and not random\n * browsers, it is reasonable to involve a mechanism to control who is\n * allowed to contact and control it. The previous section described\n * how you can exploit a token based mechanism for authenticating\n * requests, but since in this case you only need a single application,\n * or a limited set of them,\n * to be able to talk to Janus, it's worthwhile to resort to something\n * simpler and more static. To allow for that, Janus also exposes a\n * shared API secret mechanism: that is, you configure Janus with a string\n * applications need to present when sending requests, and if they don't,\n * Janus rejects them with an \\c unauthorized message.\n *\n * Configuring the API secret mechanism is easy enough: you can do that\n * either via the command line (\\c -a or \\c --apisecret ) or in the\n * \\c janus.jcfg configuration (\\c api_secret value in the \\c general section).\n * When enabled, all requests addressed to that Janus instance \\b MUST\n * also contain an \\c apisecret field in the Janus message headers. For\n * instance, this message presented above would fail:\n *\n\\verbatim\n{\n\t\"janus\" : \"create\",\n\t\"transaction\" : \"<random alphanumeric string>\"\n}\n\\endverbatim\n *\n\\verbatim\n{\n\t\"janus\" : \"error\",\n\t\"transaction\" : \"<same as request>\"\n\t\"error\" : {\n\t\t\"code\" : 403,\n\t\t\"reason\" : \"Unauthorized request (wrong or missing secret/token)\"\n\t}\n}\n\\endverbatim\n *\n * For a successful transaction, the message would have to look like this:\n *\n\\verbatim\n{\n\t\"janus\" : \"create\",\n\t\"apisecret\" : \"<API secret configured in Janus>\",\n\t\"transaction\" : \"<random alphanumeric string>\"\n}\n\\endverbatim\n *\n * The same applies for the long poll GET messages as well, which will\n * need to contain the \\c apisecret as a query string parameter.\n *\n */\n\n/*! \\page admin Admin/Monitor API\n * Recent versions of Janus introduced a new feature: an Admin/Monitor\n * API that can be used to ask Janus for more specific information\n * related to sessions and handles. This is especially useful when you\n * want to debug issues at the media level.\n *\n * \\note Right now, this new API mostly allows you to retrieve information,\n * but only act on part of it: for more interaction (e.g., to force a\n * session removal), you can rely on the existing \\ref rest for the purpose.\n * Besides, notice that this is a pull-based API. If you're interested in\n * asynchronous notifications about the internal state of core and plugins,\n * check the recently added janus_eventhandler mechanism instead.\n *\n * The API, for security reasons, is typically not enabled by default in any of the\n * transport plugins: that's definitely the case for the stock transport\n * plugins, for instance, while additional, third party plugins may choose\n * to expose the functionality without requiring any tweaking. As to the\n * existing transport, you can enable the admin API by editing the \\c [ \\c admin \\c ]\n * section in the related transport configuration file (e.g., \\c janus.transport.http.jcfg\n * for the REST interface, to use the admin API over HTTP). The configuration\n * is pretty much the same as the one for the Janus API. In addition, you\n * can configure restrictions in the form of a password/secret that clients\n * need to provide or other transport-specific ones.\n *\n * For what concerns the syntax, it's very similar to the \\ref rest and\n * so this page will briefly discuss the differences. Notice that, when\n * using WebSockets, you'll have to use <code>janus-admin-protocol</code>\n * as the subprotocol, instead of the <code>janus-protocol</code> of the\n * regular Janus API.\n *\n * \\section adminreq Admin API requests\n * There are several different requests that this API implementents, so,\n * to make this documentation easier to read and the functionality easier\n * to identify, we can group requests depending on what they provide.\n *\n * \\subsection adminreqg Generic requests\n * - \\c info: get the generic on the Janus instance; this returns exactly\n * the same information that a Janus API \\c info request would return,\n * and doesn't require any secret;\n * - \\c ping: a simple ping/pong mechanism for the Admin API, that returns\n * a \\c pong back that the client can use as a healthcheck or to measure\n * the protocol round-trip time; together with the \\c info request introduced\n * above, it's the only one that doesn't require a secret;\n * - \\c loops_info: returns a summary of how many handles each static\n * event loop is currently responsible for, in case static event loops\n * are in use (returns an empty array otherwise).\n *\n * \\subsection adminreqc Configuration-related requests\n * - \\c get_status: returns the current value for the settings that can be\n * modified at runtime via the Admin API (see below);\n * - \\c set_session_timeout: change global session timeout value in Janus;\n * - \\c set_log_level: change the log level in Janus;\n * - \\c set_log_timestamps: selectively enable/disable adding a timestamp\n * to all log lines Janus writes on the console and/or to file;\n * - \\c set_log_colors: selectively enable/disable using colors in all\n * log lines Janus writes on the console and/or to file;\n * - \\c set_locking_debug: selectively enable/disable a live debugging of\n * the locks in Janus on the fly (useful if you're experiencing deadlocks\n * and want to investigate them);\n * - \\c set_refcount_debug: selectively enable/disable a live debugging of\n * the reference counters in Janus on the fly (useful if you're experiencing\n * memory leaks in the Janus structures and want to investigate them);\n * - \\c set_min_nack_queue: change the value of the min NACK queue window;\n * - \\c set_no_media_timer: change the value of the no-media timer property;\n * - \\c set_slowlink_threshold: change the value of the slowlink-threshold property.\n *\n * \\subsection adminreqk Token-related requests\n * - \\c add_token: add a valid token (only available if you enabled the \\ref token);\n * - \\c allow_token: give a token access to a plugin (only available if you enabled the \\ref token);\n * - \\c disallow_token: remove a token access from a plugin (only available if you enabled the \\ref token);\n * - \\c list_tokens: list the existing tokens (only available if you enabled the \\ref token);\n * - \\c remove_token: remove a token (only available if you enabled the \\ref token).\n *\n * \\subsection adminreqs Session-related requests\n * - \\c accept_new_sessions: configure whether Janus should accept new\n * incoming sessions or not; this can be particularly useful whenever, e.g.,\n * you want to stop accepting new sessions because you're draining this instance;\n * - \\c list_sessions: list all the sessions currently active in Janus\n * (returns an array of session identifiers);\n * - \\c set_session_timeout: change session timeout value in Janus;\n * - \\c destroy_session: destroy a specific session; this behaves exactly\n * as the \\c destroy request does in the Janus API.\n *\n * \\subsection adminreqh Handle- and WebRTC-related requests\n * - \\c list_handles: list all the ICE handles currently active in a Janus\n * session (returns an array of handle identifiers);\n * - \\c handle_info: list all the available info on a specific ICE handle;\n * if a \\c plugin_only property is set to \\c true then only the plugin-specific\n * information is returned, excluding the more verbose WebRTC info and stats;\n * - \\c start_pcap: start dumping incoming and outgoing RTP/RTCP packets\n * of a handle to a pcap file (e.g., for ex-post analysis via Wireshark);\n * - \\c stop_pcap: stop the pcap dump;\n * - \\c start_text2pcap: same as above, but saves to a text file instead,\n * to be fed to \\c text2pcap in order to generate a \\c .pcap or \\c .pcapng file;\n * - \\c stop_text2pcap: stop the text2pcap dump;\n * - \\c message_plugin: send a synchronous request to a plugin and return a\n * response; implemented by most plugins to facilitate and streamline the\n * management of plugin resources (e.g., creating rooms in a conference plugin);\n * - \\c hangup_webrtc: hangups the PeerConnection associated with a specific\n * handle; this behaves exactly as the \\c hangup request does in the Janus API.\n * - \\c detach_handle: detached a specific handle; this behaves exactly\n * as the \\c detach request does in the Janus API.\n *\n * \\subsection adminreqt Transport-related requests\n * - \\c query_transport: send a synchronous request to a transport plugin and\n * return a response; whether this is implemented, and what functionality is\n * provided, can vary from transport to transport, but in general this feature\n * is available to tweak some setting dynamically and/or query some internal\n * transport-specific information (e.g., the number of served connections).\n *\n * \\subsection adminreqe Event handlers-related requests\n * - \\c query_eventhandler: send a synchronous request to an event handler and\n * return a response; implemented by most event handlers to dynamically\n * configure some of their properties;\n * - \\c custom_event: push a custom \"external\" event to notify via event handlers;\n * this can be useful whenever info from a third-party application needs to be\n * easily correlated to events originated by Janus, or to push information\n * Janus doesn't have available (e.g., a script polling CPU usage regularly).\n *\n * \\subsection adminreql Custom logging-related requests\n * - \\c custom_logline: push a custom \"external\" string to print on the logs;\n * this can be useful whenever info from a third-party application needs to be\n * injected in the Janus logs for whatever reason. The log level can be chosen.\n *\n * \\subsection adminreqz Helper requests\n * - \\c resolve_address: helper request to evaluate whether this Janus instance\n * can resolve an address via DNS, and how long it takes;\n * - \\c test_stun: helper request to evaluate whether this Janus instance\n * can contact a STUN server, what is returned, and how long it takes.\n *\n * \\section adminsyntax Admin API syntax\n * Following the same spirit of the \\ref rest these methods need to be\n * invoked on the right path and/or providing the right \\c session_id and\n * \\c handle_id identifiers. Specifically, the following requests must be invoked\n * without any session/handle information, as they're global requests:\n *\n * - \\c info , \\c ping , \\c get_status , all the configuration setters, all\n * the token requests, all the event-handler related requests, all the\n * helper requests, \\c accept_new_sessions and \\c list_sessions\n *\n * Here's an example of how such a request and its related response might look like:\n *\n\\verbatim\nPOST /admin\n{\n\t\"janus\" : \"list_sessions\",\n\t\"transaction\" : \"<random alphanumeric string>\",\n\t\"admin_secret\" : \"<password specified in janus.jcfg, if any>\"\n}\n\\endverbatim\n *\n *\n\\verbatim\n{\n\t\"janus\" : \"success\",\n\t\"transaction\" : \"<same as the request>\",\n\t\"sessions\" : [\n\t\t<session ID #1>,\n\t\t<session ID #2>,\n\t\t[..]\n\t\t<session ID #n>\n\t]\n}\n\\endverbatim\n *\n * On the other hand, some requests may be targeting a specific session,\n * in which case a \\c session_id property must be provided. Specifically,\n * these are the requests that do need a valid session identifier:\n *\n * - \\c destroy_session , \\c list_handles\n *\n * Using the REST API, this can be done by appending the session identifier\n (e.g., one of the ID returned by a \\c list_sessions call) to the API root,\n * but a more generic approach that works for all transports is to just\n * specify a \\c session_id property in the request, e.g.:\n *\n\\verbatim\nPOST /admin/12345678\n{\n\t\"janus\" : \"list_handles\",\n\t\"session_id\" : 12345678,\n\t\"transaction\" : \"<random alphanumeric string>\",\n\t\"admin_secret\" : \"<password specified in janus.jcfg, if any>\"\n}\n\\endverbatim\n *\n *\n\\verbatim\n{\n\t\"janus\" : \"success\",\n\t\"transaction\" : \"<same as the request>\",\n\t\"session_id\" : 12345678,\n\t\"handles\" : [\n\t\t<handle ID #1>,\n\t\t<handle ID #2>,\n\t\t[..]\n\t\t<handle ID #n>\n\t]\n}\n\\endverbatim\n *\n * Finally, some requests need not only a valid session identifier, but\n * a handle identifier as well, as they may address a specific handle\n * that the Janus instance is serving. It is the case for all requests\n * that address a specific handle and/or the related PeerConnection,\n * namely:\n *\n * - \\c handle_info , all the pcap-related requests, \\c message_plugin ,\n * \\c hangup_webrtc and \\c detach_handle\n *\n * The following is an example of how a \\c handle_info call addressing\n * a specific handle might look like. Since this is a handle-specific\n * request, the correct handle identifier must be\n * referenced, e.g., by appending the ID to the session it belongs to\n * or adding a \\c handle_id attribute besides the \\c session_id parent:\n *\n\\verbatim\nPOST /admin/12345678/98765432\n{\n\t\"janus\" : \"handle_info\",\n\t\"session_id\" : 12345678,\n\t\"handle_id\" : 98765432,\n\t\"transaction\" : \"<random alphanumeric string>\",\n\t\"admin_secret\" : \"<password specified in janus.jcfg, if any>\"\n}\n\\endverbatim\n *\n *\n\\verbatim\n{\n\t\"janus\" : \"success\",\n\t\"transaction\" : \"<same as the request>\",\n\t\"session_id\" : 12345678,\n\t\"handle_id\" : 98765432,\n\t\"info\" : {\n\t\t\"session_id\" : 12345678,\n\t\t\"session_last_activity\": 7927759122,\n\t\t\"session_transport\": \"janus.transport.websockets\",\n\t\t\"handle_id\" : 98765432,\n\t\t\"opaque_id\": \"echotest-YZcsLRCI4uSV\",\n\t\t\"loop-running\": true,\n\t\t\"created\": 18695669309,\n\t\t\"current_time\": 18706199704,\n\t\t\"plugin\": \"janus.plugin.echotest\",\n\t\t\"plugin_specific\": {\n\t\t\t// plugin specific (e.g., EchoTest internals)\n\t\t},\n\t\t\"flags\": {\n\t\t\t// flags\n\t\t},\n\t\t\"agent-created\": 18696092523,\n\t\t\"ice-mode\": \"full\",\n\t\t\"ice-role\": \"controlled\",\n\t\t\"sdps\": {\n\t\t\t\"profile\": \"UDP/TLS/RTP/SAVPF\",\n\t\t\t\"local\": \"v=0[..]\",\n\t\t\t\"remote\": \"v=0[..]\"\n\t\t},\n\t\t\"queued-packets\": 0,\n\t\t\"streams\": [\n\t\t\t// WebRTC info, including SSRCs, codecs, ICE and DTLS states, RTCP stats, etc.\n\t\t]\n\t}\n}\n\\endverbatim\n *\n * With respect to the \\c handle_info request we used as an example, here,\n * the actual content of the last response is omitted for brevity, but\n * you're welcome to experiment with it in order to check whether more\n * information (of a different nature, maybe) may be useful to have. In\n * particular, you may want to play with the plugin-specific details, as\n * different plugins will return different information according to what\n * they provide: for instance, the VideoRoom plugin might clarify whether\n * a handle is being used for publishing media or for receiving it, and\n * what are the involved IDs, the current status of the delivery, and so on.\n * At the same time, the \\c streams object will contain invaluable details\n * related to the WebRTC PeerConnection associated with the handle, as\n * in input/output statistics statistics (bytes, bytes per seconds, NACKs,\n * etc.) or the SDP/ICE/DTLS states. Notice that the information as\n * returned by the Admin API here is just a snapshot: if you're more\n * interested in how this information evolves in a more dynamic way, you\n * may want to start using the Event Handlers instead, which return pretty\n * much the same information, but conveying it as dynamic events pushed\n * to an application you control.\n *\n * \\section adminpcap Capturing unencrypted WebRTC traffic\n * As anticipated, you can also enable/disable the dumping of the RTP/RTCP\n * packets a handle is sending and receiving to a pcap or text2pcap file. This is\n * especially useful for debugging reasons, e.g., to check whether or not\n * there are issues in a specific packet Janus is sending or receiving\n * with tools like Wireshark.

By default, Janus binds on the \\c 8088 port for HTTP.\n * So, if Janus and the webserver hosting the are co-located, all you need to get your\n * application working is configure the web application to point to the right\n * address for the server. In the demos provided with these packages, this\n * is done by means of the \\c server variable:\n *\n \\verbatim\nvar server = \"http://\" + window.location.hostname + \":8088/janus\";\n \\endverbatim\n *\n * which basically tells the JavaScript application that the Janus API can be\n * contacted at the same host as the website but at a different port (8088) and path (/janus).\n * In case you configured the server differently, e.g., 7000 as the port\n * for HTTP and /my/custom/path as the API endpoint, the \\c server variable\n * could be built this way:\n *\n \\verbatim\nvar server = \"http://\" + window.location.hostname + \":7000/my/custom/path\";\n \\endverbatim\n *\n * In case the webserver and Janus are <b>NOT</b> colocated, instead, just\n * replace the \\c window.location.hostname part with the right address of\n * the server, e.g.:\n *\n \\verbatim\nvar server = \"http://www.example.com:8088/janus\";\n \\endverbatim\n *\n * It's important to point out, though, that this more \"static\" approach\n * only works if the webserver is serving files via HTTP. As soon as you\n * start involving \\b HTTPS, things start to get more complicated: in fact,\n * for security reasons you cannot contact an HTTP backend if the page is\n * made available via HTTPS. This means that if you're interested in serving\n * your web application via HTTPS, you'll need to enable the HTTPS embedded\n * webserver in Janus as well, and configure the JavaScript code to refer to\n * that itself, e.g.:\n *\n \\verbatim\nvar server = \"https://\" + window.location.hostname + \":8089/janus\";\n \\endverbatim\n *\n * assuming \\c 8089 is the port you configured Janus to use for HTTPS.\n * To make this more \"dynamic\", e.g., allow both HTTP and HTTPS instead of\n * just sticking to one, you might make use of something like this:\n *\n \\verbatim\nvar server = null;\nif(window.location.protocol === 'http:')\n\tserver = \"http://\" + window.location.hostname + \":8088/janus\";\nelse\n\tserver = \"https://\" + window.location.hostname + \":8089/janus\";\n \\endverbatim\n *\n * that is evaluate the right address to use at runtime.\n *\n * Anyway, there's a much easier way to address these scenarios, which\n * is explained in the next section.\n *\n * \\section apache Deploying Janus behind a web frontend\n *\n * To avoid most of the issues explained above, an easy approach can be\n * deploying Janus behind a frontend (e.g., Apache HTTPD, nginx, lighttpd\n * or others) that would act as a reverse proxy for incoming requests.\n * This would allow you to make the Janus API available as a relative path\n * of your web application, rather than a service reachable at a different\n * port and/or domain.\n *\n * Configuring the web application, as a consequence, would be even easier,\n * as all you'd need to do would be to provide a relative path for the API,\n * e.g.:\n *\n \\verbatim\nvar server = \"/janus\";\n \\endverbatim\n *\n * which would automatically work whether the page is served via HTTP or\n * HTTPS. In fact, all the HTTPS requests would be terminated at the webserver,\n * which would then always send simple HTTP messages to the server itself.\n *\n * An easy way to do so in Apache HTTPD is by means of the following directives:\n *\n \\verbatim\nProxyRequests Off\nProxyVia Off\nProxyPass /janus http://127.0.0.1:8088/janus retry=0\nProxyPassReverse /janus http://127.0.0.1:8088/janus\n \\endverbatim\n *\n * Different versions of HTTPD or different webservers may require a\n * different syntax, but the principle is usually always the same: you instruct\n * the webserver to act as a proxy for a local endpoint, in this case a\n * Janus instance colocated at the webserver and configured with the\n * default settings.\n *\n * A way to do the same with nginx, as explained by some Janus users\n * <a href=\"https://groups.google.com/forum/#!topic/meetecho-janus/dIv-4s0HOdw\">here</a>,\n * is the following directive:\n *\n \\verbatim\nlocation /janus {\n\tproxy_pass http://127.0.0.1:8088/janus;\n}\n \\endverbatim\n *\n * \\section webserver A quick and easy web server\n * While opening WebRTC-powered web applications by just opening the\n * application HTML files from file system works with some browsers, it\n * doesn't in others. Specifically, this works in Firefox but not in Chrome\n * (see <a href=\"https://github.com/meetecho/janus-gateway/issues/291\">issue #291</a>).\n * Anyway, considering that you will eventually want other people besides\n * you to use your Janus services, this means that to test and use Janus\n * you'll want/need to host your applications on a webserver.\n *\n * If you're not interested in configuring a full-fledged webserver, but\n * are only interested in a quick and easy way to test the demos, you can\n * make use of the embedded webservers some frameworks like PHP and Python\n * provide. To start a webserver for the demos, for instance, just open a\n * terminal in the \\c html folder of the project, and type:\n *\n *\\verbatim\nphp -S 0.0.0.0:8000\n \\endverbatim\n *\n * or:\n *\n *\\verbatim\npython -m SimpleHTTPServer 8000\n \\endverbatim\n *\n * This will setup a webserver on port \\c 8000 for you to use, meaning you'll\n * just need to have your browser open a local connection to that port to\n * try the demos:\n *\n *\\verbatim\nhttp://yourlocaliphere:8000\n \\endverbatim\n *\n * You can do the same on a different port to also access the HTML version of the Doxygen generated\n * documentation, starting the embedded webservers from the \\c docs/html\n * folder instead:\n *\n *\\verbatim\nphp -S 0.0.0.0:9000\n \\endverbatim\n *\n * or:\n *\n *\\verbatim\npython -m SimpleHTTPServer 9000\n \\endverbatim\n *\n * \\section deplyws Using Janus with WebSockets\n *\n * Configuring the use of WebSockets rather than the REST API in the JavaScript\n * library is quite trivial, as it's a matter of passing a \\c ws:// address\n * instead of an \\c http:// one to the constructor. That said, most of the same\n * considerations provided for the REST API apply here as well, e.g.,\n * to just use \\c window.location.hostname if the webserver and Janus are\n * colocated:\n *\n \\verbatim\nvar server = \"ws://\" + window.location.hostname + \":8188/\";\n \\endverbatim\n *\n * to specify the port if you change it:\n *\n \\verbatim\nvar server = \"ws://\" + window.location.hostname + \":7000/\";\n \\endverbatim\n *\n * and/or the right address of the server in case the webserver and Janus\n * are <b>NOT</b> colocated:\n *\n \\verbatim\nvar server = \"ws://www.example.com:8188/\";\n \\endverbatim\n *\n * Notice how the path (\\c /janus by default for HTTP) is not provided\n * for WebSockets, as it is ignored by the server.\n *\n * The considerations for deploying Janus behind a proxy/webserver, though,\n * differ if you use WebSockets, as most webservers don't provide an easy\n * way to proxy WebSocket requests, and usually require custom modifications\n * for the purpose. Recent versions of HTTPD (>= 2.4.5), with the right\n * module (proxy_wstunnel), do allow you to also proxy WebSockets requests the\n * same way you do with HTTP, which can be useful to do the same\n * WSS-to-WS proxying in a frontend. Here's a sample configuration:\n *\n \\verbatim\n<IfModule mod_proxy_wstunnel.c>\n\tProxyPass /janus-ws ws://127.0.0.1:8188 retry=0\n\tProxyPassReverse /janus-ws ws://127.0.0.1:8188\n</IfModule>\n \\endverbatim\n *\n * that will allow you to expose a <code>wss://myserver/janus-ws</code>\n * or <code>ws://myserver/janus-ws</code> address, and have all communication\n * forwarded to and from Janus at <code>ws://127.0.0.1:8188</code>.\n *\n * Similar configurations are probably available for other systems as well,\n * so in case this is something you're interested in, we recommend you\n * follow the best practices related to that made available by the web server developers.\n *\n * \\section both Using fallback addresses\n * As anticipated in the \\ref JS section, you can also pass an array of servers\n * to the Janus library initialization. This allows you, for instance, to\n * pass a link to both the WebSockets and REST interfaces, and have the\n * library try them both to see which one is reachable, e.g.:\n *\n \\verbatim\nvar ws_server = \"ws://\" + window.location.hostname + \":8188/\";\nvar http_server = \"http://\" + window.location.hostname + \":8088/janus\";\nvar servers = [ws_server, http_server];\n \\endverbatim\n *\n * which is especially useful if you're not sure whether or not WebSockets\n * will work in some specific networks. Please notice that, for the individual\n * servers listed in the array, the same considerations given above (e.g.,\n * in terms of relative vs. absolute linking) still apply.\n *\n * Such an approach can also be used when you've deployed several different\n * instances of Janus, and you want the library to try some and fallback\n * to others if any of them is not reachable for any reason.\n *\n */\n\n/*! \\page service Janus as a daemon/service\n *\n * By default, Janus starts in foreground, and as such works as a server\n * application that you start normally and displays output on the console.\n * That said, there are several reasons why you may not want to keep\n * Janus in the foreground, while still being interested in checking\n * the console to see what's happening.\n *\n * There are different ways to \"daemonize\" it and have it run as a service,\n * though. This page tries to summarize a few ways to do so, starting\n * from \"dumb\" approaches like sending to background and/or using screen/tmux,\n * to more sophisticated approaches involving \\c systemd, \\c upstart\n * and others.\n *\n * \\section daemon Running Janus as a daemon\n * Since version \\c 0.1.0, you can run Janus as a daemon application. To\n * do so, just pass either \\c -b or \\c --daemon as a command line\n * argument, and Janus will be daemonized. Just beware, though, that\n * since this results in stdout/stdin/stderr being closed, you MUST\n * specify a log file for Janus to use, either via command line (\\c -L\n * or \\c --log-file ) or in \\c janus.jcfg.\n *\n * \\section bg Running in background\n * Another simple way to run Janus in the background is to just append the\n * \\c & character to the command line. Anyway, this will still \"flood\" the console\n * with output from Janus. While there are ways to handle it (e.g., as\n * explained <a href=\"http://www.thegeekstuff.com/2010/05/unix-background-job/\">here</a>),\n * a nice and easy way to handle this is redirecting the output to a\n * separate file, e.g., a dedicated log:\n *\n \\verbatim\n/opt/janus/bin/janus -d 5 -6 >/path/to/mylogfile 2>&1 &\n \\endverbatim\n *\n * This is especially useful in case you want to keep a log of what\n * happened when Janus was running, and can also be used as a simple and\n * effective way to watch the console \"live\" using \\c tail:\n \\verbatim\ntail -f /path/to/mylogfile\n \\endverbatim\n *\n * \\section screen Terminal multiplexers\n * Another easy way to run Janus in the background is using terminal\n * multiplexers like \\c screen or \\c tmux. If you're not familiar with\n * such applications, you can find a quick overview\n * <a href=\"https://en.wikipedia.org/wiki/Terminal_multiplexer\">here</a>.\n *\n * The following is a simple example with \\c screen:\n *\n \\verbatim\nscreen -S janus -d -m\nscreen -r janus -X stuff $'/opt/janus/bin/janus -d 5 -6\\n'\n \\endverbatim\n *\n * This will create a session called \"janus\" and launch Janus in it with\n * a few command line options (in this case, just the option to enable\n * IPv6 support and set the debug to verbose). Janus will then be running\n * in the background: accessing the console is just a matter of attaching\n * to the \"janus\" screen:\n *\n \\verbatim\nscreen -r janus\n[CTRL+A+D to detach again]\n \\endverbatim\n *\n * Terminal multiplexers usually allow for logging the output to file\n * as well, if you want to keep an history of what happened during the\n * Janus lifetime.\n *\n * \\section systemd systemd\n * This section shows how you can add Janus as a service to\n * <a href=\"https://en.wikipedia.org/wiki/Systemd\">systemd</a>.\n *\n \\verbatim\n[Unit]\nDescription=Janus WebRTC Server\nAfter=network-online.target\nWants=network-online.target\n\n[Service]\nType=simple\nExecStart=/opt/janus/bin/janus -o\nRestart=on-abnormal\nLimitNOFILE=65536\n\n[Install]\nWantedBy=multi-user.target\n \\endverbatim\n *\n * \\note Remember to adjust the path in ExecStart to match the Janus binary path.\n *\n * \\warning Please beware that, per the default \\c RateLimitInterval and\n * and \\c RateLimitBurst values in the default systemd configuration, logger\n * messages are dropped if they arrive faster than ~33 per second.

As such, it's quite useful to spot\n * bugs and the like, as it can provide information about the values of\n * variables when they were used and the application crashed.\n *\n * First of all make sure that debugging symbols are enabled by reconfiguring Janus like this:\n *\n \\verbatim\nCFLAGS=\"-Og -g3 -ggdb3 -fno-omit-frame-pointer\" ./configure --prefix=/opt/janus\n \\endverbatim\n *\n * Once done configuring, do a \\c make \\c clean (to make sure\n * everything is recompiled from scratch) and then a \\c make and \\c make \\c install.\n *\n * When Janus crashes, you should get a core dump file somewhere.

Since it can spot memory errors, it's\n * very useful to find out about hidden race conditions and the like.\n *\n * Unlike GDB which can be used as is, though, to use Address Sanitizer\n * you'll first need to recompile Janus with some new settings, as it\n * requires a specific dependency on a library, libasan, which you'll need\n * to install through your repository manager if needed. Besides, you'll\n * need at least gcc 4.8 for this to work: older versions of gcc won't\n * work.\n *\n * Once you've installed libasan, reconfigure Janus like this:\n *\n \\verbatim\nCFLAGS=\"-O0 -g3 -ggdb3 -fno-omit-frame-pointer -fno-optimize-sibling-calls -fsanitize=address -fsanitize-address-use-after-scope -fno-sanitize-recover=all\" LDFLAGS=\"-fsanitize=address\" ./configure --prefix=/opt/janus\n \\endverbatim\n *\n * Of course you're free to add whatever additional configuration parameter\n * you were using before: the important parts are the environment variables\n * before that. Once done configuring, do a \\c make \\c clean (to make sure\n * everything is recompiled from scratch) and then a \\c make and \\c make \\c install\n * as usual.\n *\n * At this point, your Janus version should be Address Sanitizer compliant.\n * To make sure, try using \\c ldd to check whether libasan is indeed a\n * dependency or not:\n *\n \\verbatim\nldd janus | grep asan\n \\endverbatim\n *\n * If it is, you're done: whenever Janus crashes for any reason, you'll\n * get additional output from Address Sanitizer automatically with details\n * on what went wrong, and that's what you should provide as part of the\n * issue content. Just as a side note, please beware that using Address\n * Sanitizer Janus will run just a bit slower, even though not to the\n * point of being unusable (as when using, e.g., valgrind).\n *\n * \\note Please \\c DON'T paste Address Sanitizer output in the issue text.\n * Use a service like <a href=\"https://gist.github.com/\">Gist</a> or\n * <a href=\"http://pastebin.com/\">Pastebin</a> and pass the generated\n * link instead.\n *\n */\n\n/*! \\page pluginslist Plugins documentation\n * Out of the box, Janus comes with a set of different and heterogeneous\n * media manipulation plugins.

Just like media and transport\n * plugins, Event Handlers plugins in Janus themselves, meaning their\n * modular nature allows for extensibility. When enabling Event handlers,\n * Janus and other plugins generate real-time events related to several\n * different aspects that may be happening during its lifetime: these\n * events are then passed to all the available event handler plugins,\n * plugins that can then decide to do with these events whatever they want.\n * They might choose to store these events somehow, aggregate, dump or\n * process them, format and send them to an external application, and so\n * on. This really depends on what these events should be used for.\n *\n * Janus will generate events related to:\n * - session related events (e.g., session created/destroyed, etc.);\n * - handle related events (e.g., handle attached/detached, etc.);\n * - JSEP related events (e.g., got/sent offer/answer);\n * - WebRTC related events (e.g., PeerConnection up/down, ICE updates, DTLS updates, etc.);\n * - media related events (e.g., media started/stopped flowing, stats on packets/bytes, etc.);\n * - generic events originated by the Janus core (e.g., Janus started/stopped);\n * - events originated by plugins (content specific plugins themselves);\n * - events originated by transports (see above);\n * - events originated by external applications via the Admin API (content specific to source).\n *\n * \\section evhsyntax Events format\n * All events generated by Janus are JSON object, which have a shared\n * header and a custom body that will depend on the type (and in some\n * cases subtype) of the event itself.\n *\n * The header of the event will contain some information that is usually\n * common to all events: this includes \\c type and (when needed) \\c subtype\n * of the event, a timestamp in microseconds (so that you can know exactly\n * when the event was generated in the first place from the server's perspective,\n * no matter it was received), and various IDs. These IDs include the\n * session identifier (Janus session the event refers to), the handle\n * identifier (Janus handle the event refers to) and an opaque ID (set\n * by whoever controls the Janus API): as we'll see, all these IDs are\n * optional, as there are events that are not related to a session in\n * particular (e.g., a server shutdown event), but can be very important\n * for correlation purposes when they're used.\n *\n * The generic format of events is the following:\n\\verbatim\n    {\n        \"emitter\" : \"<string identifying the source of the event, if configured (optional)>\",\n        \"type\" : <numeric event type identifier>,\n        \"subtype\" : <numeric event subtype identifier (specific to the event type; optional)>,\n        \"timestamp\" : <time of when the event was generated>,\n        \"session_id\" : <unique session identifier, if provided/available (optional)>,\n        \"handle_id\" : <unique handle identifier, if provided/available (optional)>,\n        \"opaque_id\" : \"<user-provided opaque identifier, if provided/available (optional)>\",\n        \"event\" : {\n             <event body, custom depending on event type>\n        }\n    }\n\\endverbatim\n *\n * For instance, this is what an event related to a new session being created\n * would look like:\n *\n\\verbatim\n    {\n        \"emitter\": \"MyJanusInstance\",\n        \"type\": 1,\n        \"timestamp\": 1582211094846980,\n        \"session_id\": 3439056127855429,\n        \"event\": {\n            \"name\": \"created\",\n            \"transport\": {\n                \"transport\": \"janus.transport.http\",\n                \"id\": \"0x60400002c2d0\"\n            }\n        }\n    }\n\\endverbatim\n *\n * Since \\c type \\c 1 is related to session events, this event basically\n * tells us that a new session with ID \\c 3439056127855429 was created\n * (we know this from the \\c name property in the event body) on the Janus\n * instance called \\c MyJanusInstance at the timestamp \\c 1582211094846980 .\n * There are no \\c subtype , \\c handle_id or \\c opaque_id properties as\n * they were unneeded or not applicable here.\n *\n * \\section evhtypes Event types\n * As we've seen from the previous example, event types are numeric. In\n * order to figure out what you're receiving, you can refer to the\n * following table as a reference:\n *\n * <table class=\"table table-striped\">\n * <tr><th>Type</th><th>Category of event</th></tr>\n * <tr><td>1</td><td>Session related event</td></tr>\n * <tr><td>2</td><td>Handle related event</td></tr>\n * <tr><td>4</td><td>External event (injected via Admin API)</td></tr>\n * <tr><td>8</td><td>JSEP event (SDP offer/answer)</td></tr>\n * <tr><td>16</td><td>WebRTC state event (ICE/DTLS states, candidates, etc.)</td></tr>\n * <tr><td>32</td><td>Media event (media state, reports, etc.)</td></tr>\n * <tr><td>64</td><td>Plugin-originated event (e.g., event coming from VideoRoom)</td></tr>\n * <tr><td>128</td><td>Transport-originated event (e.g., WebSocket connection state)</td></tr>\n * <tr><td>256</td><td>Core event (server startup/shutdown)</td></tr>\n * </table>\n *\n * The types of events are not monotonically increasing as, internally,\n * they're represented as a mask: this allows event handler plugins to\n * only subscribe to a subset of them, rather than them all, when needed.\n *\n * The event \\c type property dictates the syntax of the \\c event body ,\n * meaning that the body for a JSEP event (type \\c 8 ) will for instance\n * be very different from a media event (type \\c 32 ). That said, the\n * format of some events can change even within the same type: for instance,\n * a WebRTC state event includes a lot of different notifications, including\n * ICE states, DTLS states, local and remote candidates, selected pair, etc.\n * In order to allow event handler recipients written in strongly typed\n * languages to be able to use different classes for the different events,\n * a different property called \\c subtype can help further discriminate\n * an event of a specified \\c type. At the time of writing, a \\c subtype\n * attribute will only be present if the event is of type \\c 256 (core),\n * \\c 16 (WebRTC) and \\c 32 (media): all other event types have a consistent\n * format, and so don't need this differentiation (e.g., type \\c 8 includes\n * both SDP offers and answers, but the nature of the SDP is indicated\n * in an attribute that has the same name in both cases).\n *\n * The available subtypes are the following:\n *\n * <table class=\"table table-striped\">\n * <tr><th colspan=2>Core subtype</th></tr>\n * <tr><td>1</td><td>Server startup</td></tr>\n * <tr><td>2</td><td>Server shutdown</td></tr>\n * <tr><th colspan=2>WebRTC subtype</th></tr>\n * <tr><td>1</td><td>ICE state</td></tr>\n * <tr><td>2</td><td>Local candidate</td></tr>\n * <tr><td>3</td><td>Remote candidate</td></tr>\n * <tr><td>4</td><td>Selected pair</td></tr>\n * <tr><td>5</td><td>DTLS state</td></tr>\n * <tr><td>6</td><td>PeerConnection state</td></tr>\n * <tr><th colspan=2>Media subtype</th></tr>\n * <tr><td>1</td><td>Medium state</td></tr>\n * <tr><td>2</td><td>Slow link</td></tr>\n * <tr><td>3</td><td>Report/stats</td></tr>\n * </table>\n *\n */\n\n/*! \\page recordings Recordings\n * Janus supports recordings of WebRTC sessions out of the box, assuming\n * plugins take advantage of the feature. Specifically, recording as a\n * functionality is implemented in the Janus core, specifically using the\n * janus_recorder structure and the related methods. When enabled, media\n * streams are recorded to a custom format (that we introduce below):\n * as such, it's then up to individual plugins to expose ways for users\n * to configure/start/stop recordings, and using the core functionality\n * to actually implementing the recording part. At the time of writing,\n * most plugins do implement it.\n *\n * \\note This section covers recordings for the purpose of storage,\n * archiving or further manipulation. If you're interested in recording\n * for the purpose of debugging media sessions, you may want to refer to\n * the \\ref adminpcap documentation instead, as that would allow you\n * to capture unencrypted RTP/RTCP packets sent/received to/from Janus\n * in a format tools like Wireshark and tcpdump support.\n *\n * \\section mjr Meetecho Janus Recordings\n * As anticipated, the janus_recorder core functionality saves media\n * streams to a custom format that we call the \"Meetecho Janus Recordings\"\n * format. When saved to file, the custom \\c mjr extension is used.\n *\n * Each \\c mjr file contains a single media stream. This means that if\n * if you want to record, for instance, an audio/video stream, you'll need\n * two separate \\c mjr files: one just for audio, and the other just for\n * video. Each \\c mjr file then basically just contains a structured\n * dump of the RTP packets exactly as they arrived: after a short header\n * that describes the data contained in the recording (i.e., type of\n * media, the codec, when it was created, when the first packet was written),\n * each RTP packet is saved together with info on its length. A partial\n * timestamp of when the packet was received is also stored, as this\n * allows for more realistic conversions to \\c pcap format when needed.\n *\n *\\verbatim\n+-----------------------------------------------+\n|               MJR00002 (8 bytes)              |\n+-----------------------------------------------+\n| LEN (2 bytes) | JSON header (variable length) |\n+-----------------------------------------------+\n|    MEET (4 bytes)     |  Recvd Time (4 bytes) |\n+-----------------------------------------------+\n| LEN (2 bytes) | RTP packet (variable length)  |\n+-----------------------------------------------+\n|    MEET (4 bytes)     |  Recvd Time (4 bytes) |\n+-----------------------------------------------+\n| LEN (2 bytes) | RTP packet (variable length)  |\n+-----------------------------------------------+\n|    MEET (4 bytes)     |  Recvd Time (4 bytes) |\n+-----------------------------------------------+\n| LEN (2 bytes) | RTP packet (variable length)  |\n+-----------------------------------------------+\n|                     ...                       |\n+-----------------------------------------------+\n \\endverbatim\n *\n * This makes the recording process very lightweight, as Janus doesn't\n * need to do anything more that just saving the packets to file: no\n * CPU intensive operation like transcoding or frame manipulation is\n * done by the janus_recorder instances. RTP packets don't even need to\n * be saved in order, as the \\c mjr files can be post-processed later\n * and, as we'll see, re-ordering of the stored packets is part of the\n * activities that our post-processor performs when doing so.\n *\n * \\subsection mjrdata Saving data channels\n * While we've so far only mentioned RTP packets, and so audio and video,\n * Janus actually also natively supports the recording of datachannels.\n * In that case, the recording will be a structured dump not of RTP\n * packets, but of the individual messages that were received. Just as\n * we said for audio and video, since \\c mjr files only cover individual\n * streams, data recordings will need their own instance as well.\n *\n * \\section mjrproc Post-processing the recordings\n * Once a recording is available in the \\c mjr format, it obviously needs\n * some transformation before it can be consumed by external tools, e.g.,\n * media players or third-party applications for further processing (like\n * muxing audio and video together, or mixing multiple video streams\n * together).\n\n * Out of the box, Janus comes with a simple post-processing tool whose\n * only job is re-ordering the available RTP packets, extracting the\n * media frames from the RTP packets (which for video might mean\n * extracting the same frame from multiple packets in sequence), and\n * saving the media frames to a well-known media format. To make this\n * simple, this tool can, for instance, convert an audio \\c mjr recording\n * to an \\c opus file, or a video \\c mjr recording containing VP8 packets\n * to a \\c webm file instead. Notice that no transcoding is done by this\n * postprocessor either: frames are extracted exactly as they were sent\n * originally, and just saved to a media container in a way that multimedia\n * applications can consume them. If further processing is needed (e.g.,\n * muxing, mixing, transcoding, or other), then this is up to third-party\n * applications that can work with existing media files.\n *\n * For more information on the Janus recordings post-processor, check\n * the documentation for the janus-pp-rec.c executable.\n *\n */\n\n/*! \\page resources Resources\n * This page contains pointers to some third-party resources, in particular\n * distro repos for an easier installation of Janus, where available,\n * applications, mobile/docker/Pi stuff, orchestration tools, client stacks,\n * libraries and bindings in other languages (that is tools that you find\n * helpful to interact with Janus outside of the context of the \\c janus.js\n * JavaScript library we provide) and so on.

its core internals and all plugins. As such, it's easy to write code\n * to fix issues, add new features, implement new modules and so on.\n *\n * You don't really need any integrated development environment (IDE) to\n * write code for Janus, but in case you do want to make use of one, you\n * may need to tweak your development environment accordingly. The Janus\n * codebase makes use of many macros defined at <code>configure</code> time\n * to figure out what's available and what should be compiled, for instance,\n * and the IDE you're using may need to be aware of those to do its job.\n *\n * The following snippet is an example of how you can configure, for instance,\n * Visual Studio Code on Ubuntu 20.04:\n *\n\\verbatim\n{\n    \"configurations\": [\n        {\n            \"name\": \"Linux\",\n            \"compilerPath\": \"/usr/bin/gcc\",\n            \"cStandard\": \"gnu17\",\n            \"includePath\": [\n                \"${workspaceFolder}/**\",\n                \"/usr/lib/x86_64-linux-gnu/glib-2.0/include\",\n                \"/usr/include/**\"\n            ],\n            \"intelliSenseMode\": \"linux-gcc-x64\",\n            \"defines\": [\n                \"CONFDIR=\\\"\\\"\",\n                \"EVENTDIR=\\\"\\\"\",\n                \"HAVE_CLOSE_ASYNC=1\",\n                \"HAS_DTLS_WINDOW_SIZE=1\",\n                \"HAVE_ICE_NOMINATION=1\",\n                \"HAVE_LIBCURL=1\",\n                \"HAVE_LIBNICE_TCP=1\",\n                \"HAVE_LIBOGG=1\",\n                \"HAVE_LIBOPUS=1\",\n                \"HAVE_LIBWEBSOCKETS_PEER_SIMPLE=1\",\n                \"HAVE_PORTRANGE=1\",\n                \"HAVE_SCTP=1\",\n                \"HAVE_SRTP_2=1\",\n                \"LOGGERDIR=\\\"\\\"\",\n                \"PLUGINDIR=\\\"\\\"\",\n                \"TRANSPORTDIR=\\\"\\\"\"\n            ]\n        }\n    ],\n    \"version\": 4\n}\n\\endverbatim\n *\n */\n\n/*! \\page README README\n *  \\verbinclude README.md\n */\n\n/*! \\page CREDITS Credits\n *\n * Janus WebRTC Server © 2014-2026 <a href=\"https://www.meetecho.com/\">Meetecho</a> (https://www.meetecho.com/)\n *\n * \\b Author:\n *         Lorenzo Miniero <lorenzo@meetecho.com>\n *\n * Several open source components have been used to implement this software:\n *\n * - \\b GLib: http://library.gnome.org/devel/glib/\n * - \\b pkg-config: http://www.freedesktop.org/wiki/Software/pkg-config/\n * - \\b Jansson: http://www.digip.org/jansson/ (JSON)\n * - \\b libconfig: https://hyperrealm.github.io/libconfig/ (configuration files)\n * - \\b libnice: https://libnice.freedesktop.org/ (ICE/STUN/TURN, at least v0.1.16 suggested, v0.1.18 recommended)\n * - \\b OpenSSL: http://www.openssl.org/ (DTLS, at least v1.0.1e)\n * - \\b libsrtp: https://github.com/cisco/libsrtp (SRTP, at least v2.x suggested)\n * - \\b usrsctp: https://github.com/sctplab/usrsctp (\\c optional, Data Channels)\n * - \\b libmicrohttpd: http://www.gnu.org/software/libmicrohttpd/ (\\c optional, Web server, at least v0.9.59)\n * - \\b libwebsockets: https://libwebsockets.org/ (\\c optional, at least v4.x suggested, WebSockets)\n * - \\b rabbitmq-c: https://github.com/alanxz/rabbitmq-c (\\c optional, v1.0.4, RabbitMQ)\n * - \\b paho.mqtt.c: https://eclipse.org/paho/clients/c (\\c optional, v1.1.0 for MQTT v3.1 & v3.1.1 or v1.3.0 for MQTT v5)\n * - \\b nanomsg: https://nanomsg.org/ (\\c optional, Nanomsg)\n * - \\b Sofia-SIP: https://github.com/freeswitch/sofia-sip (\\c optional, only needed for the SIP plugin)\n * - \\b libopus: http://opus-codec.org/ (\\c optional, only needed for the AudioBridge plugin)\n * - \\b libogg: http://xiph.org/ogg/ (\\c optional, only needed for the AudioBridge and Streaming plugins)\n * - \\b libcurl: https://curl.haxx.se/libcurl/ (\\c optional, only needed for the TURN REST API,\n * RTSP support in the Streaming plugin and the sample Event Handler plugin)\n * - \\b zlib: https://zlib.net/ (gzip compression utility)\n * - \\b Lua: https://www.lua.org/download.html (\\c optional, only needed for the Lua plugin)\n * - \\b Duktape: https://duktape.org/ (\\c optional, only needed for the Duktape plugin)\n * - \\b npm: https://docs.npmjs.com/ (\\c optional, used during build for generating JavaScript modules)\n *\n */\n\n/*! \\page COPYING License\n * This program is free software, distributed under the terms of the GNU\n * General Public License Version 3.\n *\n * If you're interested in a commercial license (e.g., because GPLv3 is\n * not suited for what you need, you're interested in technical support\n * or want to sponsor the development of new features), feel free to\n * <a href=\"https://janus.conf.meetecho.com/support\">contact us</a>.\n *\n *  \\verbinclude COPYING\n */\n\n/*! \\page CHANGELOG Tagged versions and Changelog\n * There are different tagged versions on the Janus repository. We usually\n * tag a new version any time a breaking change and/or a set of comprehensive\n * changes and fixes is going to be merged/applied to Janus, and so the\n * Changelog below can act as a simple and quick summary of which changes\n * are available in each version.\n *\n * It's very important to point out, though, that tagged version are \\b NOT\n * to be considered \\b stable versions. This is a common misunderstanding.\n * The only version we consider \\b stable is \\b master as it's the only\n * branch where we continuously provide fixes and enhancements: this is\n * particularly important in the WebRTC world, where it's not uncommon to\n * see features breaking overnight due to changes in how browsers and other\n * WebRTC devices implement things. As such, again, a tagged version is\n * \\b only a way to take a snapshot of where Janus was at a specific point\n * in time, and before a more or less major change occurred. While you're\n * free to stick to tagged versions for your deployments (e.g., because\n * that's how provisioning is usually done in your company), please notice\n * we will ignore issues and reports addressing any other branch that is\n * not master: due to lack of time and resources, we simply cannot go and\n * investigate issues we may have fixed already, so if you're experiencing\n * issues, make sure you can replicate them on master as well first.\n *\n *  \\verbinclude CHANGELOG.md\n */\n\n/*! \\page FAQ Frequently Asked Questions\n * This page contains a list of FAQ as gathered on the\n * <a href=\"https://janus.discourse.group/\">Community</a> and the\n * <a href=\"https://github.com/meetecho/janus-gateway/issues\">Issues</a>\n * page on GitHub.

It acts as a WebRTC endpoint browsers can interact\n *    with, and different modules can determine what should be done with\n *    the media. This means that you can do SIP, videoconferencing, streaming\n *    and tons of other stuff using the same box! And if what you need is\n *    not there, you can always write your own module and expand Janus.\\n\\n\n *    .\n * \\anchor meetecho\n * -# <b>What is Meetecho?</b>\\n\n *    .\n *    Meetecho is a company founded by a few researchers, post-docs and\n *    Ph.Ds coming from the Universty of Napoli Federico II. We've been\n *    working on real-time multimedia applications over the Internet for\n *    years, and at one point we decided to try and make products out\n *    of our research efforts. Our web conferencing platform and Janus\n *    are part of those efforts.\\n\\n\n *    .\n * \\anchor pronounce\n * -# <b>Now that we're at it, how is Meetecho pronounced??</b>\\n\n *    .\n *    We're being asked that a lot! We've heard so many variants and different\n *    pronounciations of the name that we could make a book out of it!\n *    When we chose the name, we wanted it to sound like\n *    <a href=\"https://www.youtube.com/watch?v=TkgDOMSv9PE\">this</a>,\n *    which means \\a awesome! in Italian. The extra H was a mistake on our\n *    side, as obviously \\a echo is pronounced differently than \\a eco! Long\n *    story short, it doesn't really matter how you pronounce it: just\n *    do it and help us be famous! :-)\\n\\n\n *    .\n * \\anchor videos\n * -# <b>I just started with Janus and am overwhelmed by the amount of info, documentation, etc... any easy way to dive in?</b>\\n\n *    .\n *    Fair point! Janus and its concepts/APIs can be a lot to digest in a short time...\n *    An easy way to start is watching one of the several presentations we've done\n *    on Janus these last months. Most if not all of them try to provide a\n *    complete introduction to the context Janus was built in, how it was\n *    born, the architecture we chose for it and so on. As such, it should\n *    be a useful starting point for whoever is interested in learning\n *    what Janus can do and how to use it.\\n\\n\n *    There are several videos available that you can find online (most of the slides\n *    available on <a href=\"https://www.slideshare.net/LorenzoMiniero/\">SlideShare</a>),\n *    here are some of them as quick pointers:\n *    -

He is usually depicted as\n *    having two faces, since he looks to the future and to the past.</i>\"\n *    Considering the general purpose nature of our server, where one face always looks\n *    at the future (WebRTC) and the other at the past (whatever the modules\n *    allows you to do, be it legacy stuff or not), Janus looked like the\n *    perfect name for it! And besides, we're Italian, Ancient Rome was\n *    awesome and mythology rules... ;-)\n *    \\n\\n\n *    .\n * \\anchor januslicense\n * -# <b>Is the license AGPLv3 or GPLv3? Do you provide alternative license mechanisms as well?</b>\\n\n *    .\n *    Janus is licensend under the GPLv3 licence. At the very beginning\n *    we chose AGPLv3 for a simple reason: we wanted our work to be open source,\n *    and we wanted interested people to play with it and contribute back\n *    whatever improvement they could provide to the core. This is not always\n *    the case with open source software, which is sometimes just seen as\n *    free stuff you can exploit without helping back, and AGPLv3 looked like\n *    the easiest way to do that. That said, we were almost immediately\n *    made aware that this license mechanism is\n *    <a href=\"https://groups.google.com/forum/?pli=1#!searchin/discuss-webrtc/janus/discuss-webrtc/LJHXkIsAaEU/fHgJ2z0sxfoJ\">not very appreciated</a>\n *    around, especially because of some\n *    interpretations about it that could affect the way proprietary stuff\n *    is deployed. We obviously cared about these concerns, and that's what\n *    eventually lead us to pick GPLv3 as a license, which should make it\n *    easier for Janus to be integrated in heterogeneous scenarios.\\n\\n\n *    Anyway, if for some reason you're not comfortable with GPLv3 for your\n *    needs, we have a <a href=\"https://janus.conf.meetecho.com/support\">commercial license</a>\n *    offering as well.\\n\\n\n *    .\n * \\anchor OS\n * -# <b>On what OS can I install Janus?</b>\\n\n *    .\n *    At the moment only Linux is officially supported. Anyway, Janus does\n *    compile on Mac OS as well, thanks to contributions from the community,\n *    and so should work fine there as well. Windows support is also provided\n *    as a <a href=\"https://github.com/meetecho/janus-gateway/pull/597\">pull request</a>\n *    by a Janus contributor: anyway, please beware that Windows support is behind the current\n *    version of development.\\n\\n\n *    .\n * \\anchor datachans\n * -# <b>Are Data Channels supported?</b>\\n\n *    .\n *    Yes they are! Starting from version \\c 0.0.3 of Janus, we added a first\n *    experimental support to Data Channels, that can as such be used in\n *    plugins that choose to support them. Right now, they are handled in\n *    several plugins like the Echo Test, VideoCall, VideoRoom and TextRoom plugins.\\n\\n\n *    Please notice that right now we only support text data: hopefully support\n *    for binary streams will be available soon as well. Until that happens,\n *    you'll have to resort to text-based encodings like Base64 to share\n *    binary data through Janus.\\n\\n\n *    .\n * \\anchor usrsctp\n * -# <b>I don't care about Data Channels, do I have to compile usrsctp anyway?</b>\\n\n *    .\n *    Support for Data Channels is optional, so if you didn't install the library\n *    the configure script will go around them and compile Janus without Data Channels\n *    support. If you did install the library and don't care about Data Channels,\n *    but only about audio and/or video, pass the \\c --disable-data-channels\n *    option to the configure script to explicitly disable them. If you're updating\n *    an existing install, issue a \\c make \\c clean before compiling again, or\n *    you might encounter issues with pre-existing symbols.\\n\\n\n *    .\n * \\anchor usrsctperr\n * -# <b>I can't install usrsctp, I'm getting errors about dereferencing pointers?</b>\\n\n *    .\n *    Apparently recent compilers are stricter with respect to some code\n *    syntaxes, and this seems to be affecting the way \\c usrsctp is written\n *    as of now. Some users managed to fix this issue by passing an export\n *    before the \\c bootstrap and \\c configure steps in the \\c usrsctp\n *    compilation:\\n\\n\n *\\verbatim\n   export CFLAGS=\"-fno-strict-aliasing\" ./bootstrap\n   export CFLAGS=\"-fno-strict-aliasing\" ./configure --prefix=/usr\n   make && make install\n \\endverbatim\n *    Another solution seems to be removing all the \\c -O2 occurrences\n *    in the generated \\c configure script.\\n\\n\n *    .\n * \\anchor gateway\n * -# <b>Can I use Janus as a gateway to my Freeswitch/Kamailio/Asterisk/other SIP infrastructure?</b>\\n\n *    .\n *    Of course! One of the modules we provide out of the box is a SIP\n *    gateway plugin based on the <a href=\"https://github.com/freeswitch/sofia-sip\">Sofia-SIP</a>\n *    library stack. These plugin allows a web user to register at a SIP\n *    proxy/server either as an authenticated user or as a guest, and\n *    start or receive calls from other SIP users, including other web users\n *    exploiting the same plugin. Janus will take care of all the WebRTC-related\n *    stuff (ICE, DTLS, SRTP), which means that on the SIP side it will\n *    be plain RTP only, much easier and lighter to handle for legacy\n *    implementations. SDES-SRTP is also supported on the SIP side in case\n *    it is required.\\n\\n\n *    .\n * \\anchor jssip\n * -# <b>Can I use existing SIP stacks (e.g., JsSIP) with Janus?</b>\\n\n *    .\n *    Janus uses a custom JSON-based protocol for all the communication\n *    between web users and plugins in the server, so no, that's not\n *    possible right now. While there are some controls that give you access\n *    to some of the SIP details (e.g., requesting SRTP negotiation or injecting\n *    custom headers), the SIP plugin in Janus only exposes some very\n *    high level information to web users (e.g., registration failed/succeeded,\n *    incoming call, decline, hangup, etc.), without delving in any SIP-related\n *    detail, which is instead completely demanded to the server-side plugin\n *    itself. This ensures that web users can take advantage of SIP functionality\n *    in an easy way, without having to worry about the details and complexity\n *    of SIP within JavaScript.\\n\\n\n *    .\n * \\anchor transcoding\n * -# <b>Does Janus support transcoding?</b>\\n\n *    .\n *    Janus is a simple intermediary between WebRTC users and server-side\n *    plugins providing application logic, so no, it doesn't provide any\n *    transcoding functionality per-se. If transcoding is needed, this is\n *    supposed to be implemented within plugins themselves. That said,\n *    apart from the AudioBridge plugin which acts as an audio MCU,\n *    none of the plugins we provide out-of the box does transcoding,\n *    since we wanted the implementation to be lightweight and besides\n *    there are several existing tools and third-party implementations that\n *    could be leveraged for the purpose.\\n\\n\n *    .\n * \\anchor recording\n * -# <b>Does Janus support recording?</b>\\n\n *    .\n *    Yep! The Janus core provides an integrated way of recording all\n *    the media streams that go through it, whether it's audio, video or\n *    data, and almost all stock plugins do exploit it one way or another.\n *    Recording is implemented as a structured dump of all RTP and data\n *    files exactly as they were transmitted or sent: as such, no manipulation\n *    is done while recording, and all post-processing is demanded to\n *    an external tool. For more information on this, check the\n *    <a href=\"https://janus.conf.meetecho.com/docs/janus-pp-rec_8c.html#details\">documentation</a>.\\n\\n\n *    .\n * \\anchor websockets\n * -# <b>Can I use WebSockets instead of plain HTTP to interact with Janus?</b>\\n\n *    .\n *    Since version \\c 0.0.4, you can! At first we chose a REST-based plain HTTP communication\n *    for a simple reason: we noticed that there were some scenarios (e.g.,\n *    client firewalls) where websockets wouldn't work, even though WebRTC\n *    did. To improve the chances of success in the communication, we\n *    then chose this simpler approach with respect to signalling. Besides,\n *    plain HTTP is much easier to proxy and/or place behind frontends\n *    like Apache HTTPD or nginx than WebSockets, another aspect that\n *    played a decisive role in our decision, as we were also very interested\n *    in making the integration of Janus in heterogeneous environments\n *    as easy as possible. That said, WebSockets also provide substantial\n *    benefits when compared to plain HTTP, and definitely make life easier to\n *    server side integrators as well, e.g., in terms of overhead and use of\n *    resources. For more information, check the \\ref WS page. \\n\\n\n *    .\n * \\anchor rabbitmq\n * -# <b>Can I use RabbitMQ instead of HTTP/WebSockets to interact with Janus?</b>\\n\n *    .\n *    Since version \\c 0.0.6, you can! This is a feature that several\n *    developers asked for, especially those that are interested in wrapping\n *    the Janus API on the server side, and implement the communication\n *    on the client side their own way. Specifically, Janus now supports\n *    RabbitMQ based messaging as an alternative \"transport\" for API\n *    requests, responses and notifications, meaning it can be used with\n *    or without HTTP and WebSockets, depending on your requirements.\n *    For more information, check the \\ref rabbit page. \\n\\n\n *    .\n * \\anchor unixsockets\n * -# <b>Can I use Unix Sockets instead of HTTP/WebSockets/RabbitMQ to interact with Janus?</b>\\n\n *    .\n *    Since version \\c 0.2.1, you can! More specifically, you can use a\n *    \\c SOCK_SEQPACKET or a \\c SOCK_DGRAM socket to control a Janus instance.\n *    Notice that this feature is only available when installing Janus on a Linux machine.\n *    For more information, check the \\ref unix page. \\n\\n\n *    .\n * \\anchor mqtt\n * -# <b>Can I use MQTT instead of HTTP/WebSockets/RabbitMQ/Unix Sockets to interact with Janus?</b>\\n\n *    .\n *    Since version \\c 0.2.1, you can! This was a very welcome contribution by\n *    a Janus user, as it makes it even easier to have Janus interact with IoT deployments.\n *    For more information, check the \\ref apimqtt page. \\n\\n\n *    .\n * \\anchor nanomsg\n * -# <b>Can I use Nanomsg instead of HTTP/WebSockets/RabbitMQ/MQTT/Unix Sockets to interact with Janus?</b>\\n\n *    .\n *    Since version \\c 0.4.2, you can! For more information, check the \\ref apinanomsg page. \\n\\n\n *    .\n * \\anchor transports\n * -# <b>What about \\<my favourite control protocol\\> instead?</b>\\n\n *    .\n *    Since version \\c 0.1.0, the transports for the Janus API have been made\n *    modular. This means that, assuming a transport plugin implementing\n *    support for your favourite protocol has been made available, you\n *    can just add it to the Janus transport modules folder and it should\n *    work. If no plugin has been implemented, you may even want to do so\n *    yourself, or ask for ours or others help.\\n\\n\n *    .\n * \\anchor demos\n * -# <b>I've launched Janus, how do I try the demos?</b>\\n\n *    .\n *    The demos are available in the \\c html folder in the project. That\n *    said, the integrated web server in Janus does not serve static files\n *    as well, so you'll have to make them available using a different\n *    webserver. Details about how to deploy Janus are provided in\n *    \\ref deploy.\\n\\n\n *    .\n * \\anchor certificates\n * -# <b>I'm trying the demos, but I get \"Janus down\" or certificate errors!</b>\\n\n *    .\n *    Again, make sure you've read and are following the instructions on how to\n *    effectively deploy Janus in \\ref deploy. Most likely you're either trying\n *    to open the WebRTC demos using HTTP instead of HTTPS (something that\n *    browsers will not allow, if not on localhost for testing), trying\n *    to contact Janus via an insecure protocol through a secure page, or\n *    using an insecure certificate for Janus itself. All of these problems\n *    are explained and solved easily in the \\ref deploy documentation.\\n\\n\n *    .\n * \\anchor nodejs\n * -# <b>Can I use Janus with node.js or other frameworks?</b>\\n\n *    .\n *    Not natively, but since interaction with Janus is demanded to\n *    a JSON based communication transported on a network protocol (HTTP,\n *    WebSockets, RabbitMQ and others), this can be abstracted quite easily\n *    in several different ways. A common approach is implementing the Janus\n *    API in a server-side application, so that you handle users your own way\n *    and with your own API, while controlling Janus as a media server yourself\n *    by wrapping its API. Check the \\ref resources documentation page\n *    for a list of Janus API wrappers in different programming languages\n *    that ou can use within your application\n *    to control a Janus instance from there instead of the browser. Should\n *    you decide to write your own Janus API wrapper, don't hesitate to let\n *    us know so that we can advertise yours there too!\\n\\n\n *    .\n * \\anchor monitoring\n * -# <b>How do I monitor/manage my Janus instance?</b>\\n\n *    .\n *    Since version \\c 0.2.2 there are a couple of different ways you can do\n *    that. The first and most immediate one is making use of the Admin API,\n *    which you can find documented in the \\ref admin page. It is a request/response\n *    protocol that can be used to poll information on existing sessions and\n *    handles, and which also provides a lot of useful WebRTC-related information\n *    on PeerConnections Janus is managing. You can also find a very useful\n *    <a href=\"https://www.meetecho.com/blog/understanding-the-janus-admin-api\">blog post</a>\n *    where we describe in detail how the Admin API can be used to investigate issues. \\n\\n\n *    A more recent, and potentially much more powerful, addition to Janus\n *    are the Event Handlers. Unlike the Admin API, which is query-based,\n *    Event Handlers provide a mechanism to dynamically feed you with real-time\n *    and live data on whatever is happening within Janus, whether it's the\n *    core or any of the plugins. You can find more information, along with\n *    an example of how to receive such events, in the\n *    <a href=\"https://github.com/meetecho/janus-gateway/pull/536\">pull request</a>\n *    page from where this effort was merged. More guidelines and implementations\n *    will definitely follow. \\n\\n\n *    .\n * \\anchor writeplugin\n * -# <b>I want to write my own plugin, where do I start?</b>\\n\n *    .\n *    Great! Depending on the kind of plugin you want to implement (application plugin,\n *    transport plugin, event handler plugin), some of the details may change,\n *    but the concept is typically the same. There are APIs you can refer to,\n *    documented in \\ref pluginapi , \\ref transportapi and \\ref eventhandlerapi.\n *    The existing plugins are also an excellent way to start to get\n *    comfortable with the API: a good starting point may be the Echo Test\n *    plugin, which is a very simple and barebone implementation that\n *    simply bounces back whatever it is sent, and also involves some\n *    rough application logic to determine its behaviour (e.g., messages\n *    coming from web users that selectively enable or disable video).\n *    You may want to check third-party plugins as well in the \\ref resources\n *    as well, as they'll give you an idea of how other users did the same.\n *    If you need any help with this, feel free to ask for help on the Google group:\n *    we're always excited whenever new Janus plugins are realized!\\n\\n\n *    .\n * \\anchor ulimit\n * -# <b>I'm using the VideoRoom plugin and, when several users are handled, I get\n *    a \"Too many open files\" errors and Janus crashes</b>\\n\n *    .\n *    As all applications on Linux environments, Janus is bound to the\n *    constraints imposed by the OS and/or the user. One of these constraints\n *    is related to how many file descriptors the application, or all the\n *    applications, can open. On several distributions this number is, by\n *    default, quite low, which can cause the issue you experienced. This\n *    value, together with others, can be modified, per-user or for all users,\n *    using the \\c ulimit application. For a simple and quick way to handle\n *    this refer to the guide provided by the MongoDB developers:\n *    http://docs.mongodb.org/manual/reference/ulimit/ \\n\\n\n *    .\n * \\anchor aesgcm\n * -# <b>I get an undefined reference to <code>srtp_crypto_policy_set_aes_gcm_256_16_auth</code>\n *    when building Janus</b>\\n\n *    .\n *    As explained in the README, you have to build libsrtp or libsrtp2 with\n *    the <code>--enable-openssl</code> or <code>--enable-nss</code> flags,\n *    since they're needed to support AES-GCM in our SRTP streams. If you\n *    don't want AES-GCM support, pass the <code>--disable-aes-gcm</code>\n *    option when configuring Janus instead: remember to do a\n *    <code>make clean</code> before recompiling Janus after the change. \\n\\n\n *    .\n * \\anchor https\n * -# <b>When I enable the HTTPS web server in Janus, the CPU goes crazy</b>\\n\n *    .\n *    As discussed in a recent <a href=\"https://groups.google.com/forum/?pli=1#!topic/meetecho-janus/lD8A0VqXsNs\">post</a>\n *    on our Google group, this is caused by an occasional problem within\n *    libmicrohttpd, the library we use to implement an embedded web server\n *    in Janus. This is not deterministic, as the high CPU usage does happen\n *    on some distributions (e.g., Ubuntu 12.04), while it doesn't on\n *    others (e.g., Ubuntu 14.04). Anyway, this only can happen if you enable\n *    HTTPS support within Janus itself: you can still have a safe HTTPS\n *    usage with Janus if you deploy it behind a frontend (e.g., Apache HTTPD)\n *    that takes care of this on its behalf. Refer to the \\ref deploy section\n *    for more details about this.\\n\\n\n *    .\n * \\anchor turn\n * -# <b>I enabled TURN in the Janus configuration, but my clients behind a firewall can't connect</b>\\n\n *    .\n *    As explained in the \\c janus.jcfg documentation, the TURN settings you\n *    configure there refer to Janus \\b itself, \\b not the clients that make use\n *    of its services. This means that, whether you configure a static TURN\n *    server and the related credentials, or the REST API client stack to\n *    retrieve them dynamically, you're asking Janus to gather relay candidates\n *    for ITSELF. This is only useful if you know that your Janus instance\n *    will not be deployed on a public address (as it usually will) but will\n *    instead potentially sit behind a restrictive component like a firewall,\n *    or if you simply want to limit the number of open ports and so force\n *    all media traffic to go through the TURN server port alone.\\n\\n\n *    If you want your clients to gather relay candidates, instead, this\n *    needs to be done on the client side (e.g., in JavaScript, if your\n *    clients are web applications). If you're using our \\ref JS check\n *    the \\c echotest.js code, which has a commented portion that explains\n *    how to provide one or more TURN servers to make use of. If you're\n *    handling the WebRTC-related stuff on your own and are contacting\n *    Janus some other way, please refer to the related way of specifying\n *    STUN and TURN servers instead.\\n\\n\n *    .\n * \\anchor benchmark\n * -# <b>Is there any benchmark on Janus performances?</b>\\n\n *    .\n *    Benchmarking Janus is not an easy task, especially if we consider\n *    its general purpose nature. In fact, Janus by itself does not much\n *    more than negotiating WebRTC PeerConnections and relaying frames\n *    around, while most of the application login is in the modules. As\n *    you can imagine, different modules may have very different requirements\n *    and impact on the performances. For instance, the Echo Test is probably\n *    much lighter than the Video SFU, even if they're handling the same\n *    number of users. This means that such a benchmarking does not have\n *    much sense unless you contextualise the scenarios.\\n\\n\n *    You can find some results on tests we made ourselves in a couple of\n *    publications we wrote and available\n *    <a href=\"https://janus.conf.meetecho.com/citeus\">here</a>. One of those\n *    introduces a WebRTC stress testing tool we implemented called Jattack,\n *    for which a <a href=\"https://www.youtube.com/watch?v=UwNq8p0m1js\">video of the presentation</a>\n *    is available. You can find some more details and considerations in an older\n *    <a href=\"https://groups.google.com/forum/?pli=1#!topic/meetecho-janus/ydGcbMt7IX0\">post</a>\n *    on our Google group too.\\n\\n\n *    .\n * \\anchor scaling\n * -# <b>How do I scale Janus?</b>\\n\n *    .\n *    This question is way too generic to answer here. As explained in the previous\n *    point, Janus is not an easily measurable entity, as it very much depends\n *    on which of the plugins you're involving in the scenarios that interest you\n *    and how. The same considerations also apply to scaling the scenario you\n *    implemented, as different plugins may require different approaches to\n *    do that. \\n\\n\n *    In general, Janus does not have any built-in multi-tenant support. Each\n *    Janus instance is conceived to be standalone, and works by itself. That\n *    said, there are different ways in which you can implement scalability in\n *    your service. One of them is implementing a wrapper/controller application\n *    that is in charge of multiple Janus instances, so that it can distribute\n *    the load depending on the requests. If the scenario allows for it,\n *    you can also mix concepts from different plugins on different Janus\n *    instances (e.g., use the RTP forwardiing feature of the VideoRoom plugin\n *    to make the same VideoRoom publisher available as a Streaming mountpoint\n *    on other Janus machines). Anyway, as explained each application may have\n *    very different requirements when it comes to scalability. \\n\\n\n *    Should you be interested in implementing scalability in your application and\n *    need help, <a href=\"https://janus.conf.meetecho.com/support\">contact us</a>.\\n\\n\n *    .\n * \\anchor requests\n * -# <b>Can you implement a feature/plugin/application I want?</b>\\n\n *    .\n *    We're constantly working on new features and on improving what's\n *    already there, and we do love feedback from users. That said, we're\n *    a small team and we do have to pay our bills, so we always have to\n *    reserve our resources wisely. If there's a feature you'd like to\n *    see implemented, tell us on our Google group, and discuss it with\n *    other users: it may be on our schedule, or someone else may be\n *    already working on it to contribute it back to the project. You\n *    may even want to try and build it yourself and help us make Janus\n *    even better! \\n\\n\n *    If you really need something that isn't there, you may also want to consider\n *    <a href=\"https://janus.conf.meetecho.com/support\">contacting us</a>\n *    for a sponsored development or consulting.\\n\\n\n *    .\n * \\anchor learning\n * -# <b>I want to learn more on Janus!</b>\\n\n *    .\n *    That's great!

Although I think I got rid of\n   all the major bugs and I don't expect the API to change anymore, there\n   may be something I've missed. So use with caution.\n\n   This algorithm is based on this original resampling algorithm:\n   Smith, Julius O. Digital Audio Resampling Home Page\n   Center for Computer Research in Music and Acoustics (CCRMA),\n   Stanford University, 2007.\n   Web published at https://ccrma.stanford.edu/~jos/resample/.\n\n   There is one main difference, though. This resampler uses cubic\n   interpolation instead of linear interpolation in the above paper. This\n   makes the table much smaller and makes it possible to compute that table\n   on a per-stream basis. In turn, being able to tweak the table for each\n   stream makes it possible to both reduce complexity on simple ratios\n   (e.g. 2/3), and get rid of the rounding operations in the inner loop.\n   The latter both reduces CPU time and makes the algorithm more SIMD-friendly.\n*/\n\n#ifdef HAVE_CONFIG_H\n#include \"config.h\"\n#endif\n\n#ifdef OUTSIDE_SPEEX\n#include <stdlib.h>\nstatic void *speex_alloc(int size) {return calloc(size,1);}\nstatic void *speex_realloc(void *ptr, int size) {return realloc(ptr, size);}\nstatic void speex_free(void *ptr) {free(ptr);}\n#ifndef EXPORT\n#define EXPORT\n#endif\n#include \"speex_resampler.h\"\n#include \"arch.h\"\n#else /* OUTSIDE_SPEEX */\n\n#include \"speex/speex_resampler.h\"\n#include \"arch.h\"\n#include \"os_support.h\"\n#endif /* OUTSIDE_SPEEX */\n\n#include <math.h>\n#include <limits.h>\n\n#ifndef M_PI\n#define M_PI 3.14159265358979323846\n#endif\n\n#define IMAX(a,b) ((a) > (b) ?

Peers can then mute/unmute themselves by sending specific messages\n * to the plugin: any way a peer mutes/unmutes, an event is triggered\n * to the other participants, so that it can be rendered in the UI\n * accordingly.\n *\n * Rooms to make available are listed in the plugin configuration file.\n * A pre-filled configuration file is provided in \\c conf/janus.plugin.audiobridge.jcfg\n * and includes a demo room for testing.\n *\n * To add more rooms or modify the existing one, you can use the following\n * syntax:\n *\n * \\verbatim\nroom-<unique room ID>: {\n\tdescription = This is my awesome room\n\tis_private = true|false (private rooms don't appear when you do a 'list' request)\n\tsecret = <optional password needed for manipulating (e.g. destroying) the room>\n\tpin = <optional password needed for joining the room>\n\tsampling_rate = <sampling rate> (e.g., 16000 for wideband mixing)\n\tspatial_audio = true|false (if true, the mix will be stereo to spatially place users, default=false)\n\taudiolevel_ext = true|false (whether the ssrc-audio-level RTP extension must be\n\t\tnegotiated/used or not for new joins, default=true)\n\taudiolevel_event = true|false (whether to emit event to other users or not, default=false)\n\taudio_active_packets = 100 (number of packets with audio level, default=100, 2 seconds)\n\taudio_level_average = 25 (average value of audio level, 127=muted, 0='too loud', default=25)\n\tdefault_expectedloss = percent of packets we expect participants may miss, to help with outgoing FEC (default=0, max=20; automatically used for forwarders too)\n\tdefault_bitrate = default bitrate in bps to use for the all participants (default=0, which means libopus decides; automatically used for forwarders too)\n\tdenoise = true|false (whether denoising via RNNoise should be performed for each participant by default)\n\trecord = true|false (whether this room should be recorded, default=false)\n\trecord_file = /path/to/recording.wav (where to save the recording)\n\trecord_dir = /path/to/ (path to save the recording to, makes record_file a relative path if provided)\n\tmjrs = true|false (whether all participants in the room should be individually recorded to mjr files, default=false)\n\tmjrs_dir = \"/path/to/\" (path to save the mjr files to)\n\tallow_rtp_participants = true|false (whether participants should be allowed to join\n\t\tvia plain RTP as well, rather than just WebRTC, default=false)\n\tgroups = optional, non-hierarchical, array of groups to tag participants, for external forwarding purposes only\n\n\t\t[The following lines are only needed if you want the mixed audio\n\t\tto be automatically forwarded via plain RTP to an external component\n\t\t(e.g., an ffmpeg script, or a gstreamer pipeline) for processing.\n\t\tBy default plain RTP is used, SRTP must be configured if needed]\n\trtp_forward_id = numeric RTP forwarder ID for referencing it via API (optional: random ID used if missing)\n\trtp_forward_host = host address to forward RTP packets of mixed audio to\n\trtp_forward_host_family = ipv4|ipv6; by default, first family returned by DNS request\n\trtp_forward_port = port to forward RTP packets of mixed audio to\n\trtp_forward_ssrc = SSRC to use to use when streaming (optional: stream_id used if missing)\n\trtp_forward_codec = opus (default), pcma (A-Law) or pcmu (mu-Law)\n\trtp_forward_ptype = payload type to use when streaming (optional: only read for Opus, 100 used if missing)\n\trtp_forward_group = group of participants to forward, if enabled in the room (optional: forwards full mix if missing)\n\trtp_forward_srtp_suite = length of authentication tag, if SRTP is needed (32 or 80)\n\trtp_forward_srtp_crypto = key to use as crypto, if SRTP is needed (base64 encoded key as in SDES)\n\trtp_forward_always_on = true|false, whether silence should be forwarded when the room is empty (optional: false used if missing)\n}\n\\endverbatim\n *\n * \\section bridgeapi Audio Bridge API\n *\n * The Audio Bridge API supports several requests, some of which are\n * synchronous and some asynchronous. There are some situations, though,\n * (invalid JSON, invalid request) which will always result in a\n * synchronous error response even for asynchronous requests.\n *\n * \\c create, \\c edit, \\c destroy, \\c exists, \\c allowed, \\c kick, \\c list,\n * \\c mute, \\c unmute, \\c mute_room, \\c unmute_room, \\c listparticipants,\n * \\c listannouncements, \\c resetdecoder, \\c rtp_forward, \\c stop_rtp_forward,\n * \\c list_forwarders, \\c play_file, \\c is_playing, \\c stop_file and \\c stop_all_files\n * are synchronous requests, which means you'll get a response directly within\n * the context of the transaction. \\c create allows you to create a new audio\n * conference bridge dynamically, as an alternative to using the configuration file;\n * \\c edit allows you to dynamically edit some room properties (e.g., the PIN);\n * \\c destroy removes an audio conference bridge and destroys it, kicking\n * all the users out as part of the process; \\c exists allows you to\n * check whether a specific audio conference exists; \\c allowed allows\n * you to edit who's allowed to join a room via ad-hoc tokens; \\c list\n * lists all the available rooms, while \\c listparticipants lists all\n * the participants of a specific room and their details; \\c listannouncements\n * lists all playing announcements of a specific room and their details;\n * \\c resetdecoder marks the Opus decoder for the participant as invalid, and\n * forces it to be recreated (which might be needed if the audio for generated\n * by the participant becomes garbled); \\c rtp_forward allows you to forward\n * the mix of an AudioBridge room via RTP to a separate component (e.g.,\n * for broadcasting it to a wider audience, or for processing/recording),\n * whereas \\c stop_rtp_forward can remove an existing forwarder; a list\n * of configured forwarders for a room can be retrieved using the\n * \\c list_forwarders request; finally, \\c play_file allows you to\n * reproduce an audio .opus file in a mix (e.g., to play an announcement\n * or some background music), \\c is_playing checks if a specific file is\n * still playing, while \\c stop_file will stop such a playback instead and\n * \\c stop_all_files will stop all announcements.\n *\n * The \\c join , \\c configure , \\c changeroom and \\c leave requests\n * instead are all asynchronous, which means you'll get a notification\n * about their success or failure in an event. \\c join allows you to\n * join a specific audio conference bridge; \\c configure can be used\n * to modify some of the participation settings (e.g., mute/unmute);\n * \\c changeroom can be used to leave the current room and move to a\n * different one without having to tear down the PeerConnection and\n * recreate it again (useful for sidebars and \"waiting rooms\"); finally,\n * \\c leave allows you to leave an audio conference bridge for good.\n *\n * The AudioBridge plugin also allows you to forward the mix to an\n * external listener, e.g., a gstreamer/ffmpeg pipeline waiting to\n * process the mixer audio stream. You can add new RTP forwarders with\n * the \\c rtp_forward request; a \\c stop_rtp_forward request removes an\n * existing RTP forwarder; \\c listforwarders lists all the current RTP\n * forwarders on a specific AudioBridge room instance. As an alternative,\n * you can configure a single static RTP forwarder in the plugin\n * configuration file. A finer grained control of what to forward\n * externally, in terms of participants mix, can be achieved using\n * groups.\n *\n * \\c create can be used to create a new audio room, and has to be\n * formatted as follows:\n *\n\\verbatim\n{\n\t\"request\" : \"create\",\n\t\"room\" : <unique numeric ID, optional, chosen by plugin if missing>,\n\t\"permanent\" : <true|false, whether the room should be saved in the config file, default=false>,\n\t\"description\" : \"<pretty name of the room, optional>\",\n\t\"secret\" : \"<password required to edit/destroy the room, optional>\",\n\t\"pin\" : \"<password required to join the room, optional>\",\n\t\"is_private\" : <true|false, whether the room should appear in a list request>,\n\t\"allowed\" : [ array of string tokens users can use to join this room, optional],\n\t\"sampling_rate\" : <sampling rate of the room, optional, 16000 by default>,\n\t\"spatial_audio\" : <true|false, whether the mix should spatially place users, default=false>,\n\t\"audiolevel_ext\" : <true|false, whether the ssrc-audio-level RTP extension must be negotiated for new joins, default=true>,\n\t\"audiolevel_event\" : <true|false (whether to emit event to other users or not)>,\n\t\"audio_active_packets\" : <number of packets with audio level (default=100, 2 seconds)>,\n\t\"audio_level_average\" : <average value of audio level (127=muted, 0='too loud', default=25)>,\n\t\"default_expectedloss\" : <percent of packets we expect participants may miss, to help with outgoing FEC (default=0, max=20; automatically used for forwarders too)>,\n\t\"default_bitrate\" : <bitrate in bps to use for the all participants (default=0, which means libopus decides; automatically used for forwarders too)>,\n\t\"denoise\" : <true|false, whether denoising via RNNoise should be performed for each participant by default, default=false>,\n\t\"record\" : <true|false, whether to record the room or not, default=false>,\n\t\"record_file\" : \"</path/to/the/recording.wav, optional>\",\n\t\"record_dir\" : \"</path/to/, optional; makes record_file a relative path, if provided>\",\n\t\"mjrs\" : <true|false (whether all participants in the room should be individually recorded to mjr files, default=false)>,\n\t\"mjrs_dir\" : \"</path/to/, optional>\",\n\t\"allow_rtp_participants\" : <true|false, whether participants should be allowed to join via plain RTP as well, default=false>,\n\t\"groups\" : [ non-hierarchical array of string group names to use to gat participants, for external forwarding purposes only, optional]\n}\n\\endverbatim\n *\n * A successful creation procedure will result in a \\c created response:\n *\n\\verbatim\n{\n\t\"audiobridge\" : \"created\",\n\t\"room\" : <unique numeric ID>,\n\t\"permanent\" : <true if saved to config file, false if not>\n}\n\\endverbatim\n *\n * If you requested a permanent room but a \\c false value is returned\n * instead, good chances are that there are permission problems.\n *\n * An error instead (and the same applies to all other requests, so this\n * won't be repeated) would provide both an error code and a more verbose\n * description of the cause of the issue:\n *\n\\verbatim\n{\n\t\"audiobridge\" : \"event\",\n\t\"error_code\" : <numeric ID, check Macros below>,\n\t\"error\" : \"<error description as a string>\"\n}\n\\endverbatim\n *\n * Notice that, in general, all users can create rooms. If you want to\n * limit this functionality, you can configure an admin \\c admin_key in\n * the plugin settings. When configured, only \"create\" requests that\n * include the correct \\c admin_key value in an \"admin_key\" property\n * will succeed, and will be rejected otherwise. Notice that you can\n * optionally extend this functionality to RTP forwarding as well, in\n * order to only allow trusted clients to use that feature.\n *\n * Once a room has been created, you can still edit some (but not all)\n * of its properties using the \\c edit request. This allows you to modify\n * the room description, secret, pin and whether it's private or not: you\n * won't be able to modify other more static properties, like the room ID,\n * the sampling rate, the extensions-related stuff and so on. If you're\n * interested in changing the ACL, instead, check the \\c allowed message.\n * An \\c edit request has to be formatted as follows:\n *\n\\verbatim\n{\n\t\"request\" : \"edit\",\n\t\"room\" : <unique numeric ID of the room to edit>,\n\t\"secret\" : \"<room secret, mandatory if configured>\",\n\t\"new_description\" : \"<new pretty name of the room, optional>\",\n\t\"new_secret\" : \"<new password required to edit/destroy the room, optional>\",\n\t\"new_pin\" : \"<new PIN required to join the room, PIN will be removed if set to an empty string, optional>\",\n\t\"new_is_private\" : <true|false, whether the room should appear in a list request>,\n\t\"new_record_dir\" : \"<new path where new recording files should be saved>\",\n\t\"new_mjrs_dir\" : \"<new path where new MJR files should be saved>\",\n\t\"permanent\" : <true|false, whether the room should be also removed from the config file, default=false>\n}\n\\endverbatim\n *\n * A successful edit procedure will result in an \\c edited response:\n *\n\\verbatim\n{\n\t\"audiobridge\" : \"edited\",\n\t\"room\" : <unique numeric ID>\n}\n\\endverbatim\n *\n * On the other hand, \\c destroy can be used to destroy an existing audio\n * room, whether created dynamically or statically, and has to be\n * formatted as follows:\n *\n\\verbatim\n{\n\t\"request\" : \"destroy\",\n\t\"room\" : <unique numeric ID of the room to destroy>,\n\t\"secret\" : \"<room secret, mandatory if configured>\",\n\t\"permanent\" : <true|false, whether the room should be also removed from the config file, default=false>\n}\n\\endverbatim\n *\n * A successful destruction procedure will result in a \\c destroyed response:\n *\n\\verbatim\n{\n\t\"audiobridge\" : \"destroyed\",\n\t\"room\" : <unique numeric ID>,\n\t\"permanent\" : <true|false, whether the room is also removed from the config file>\n}\n\\endverbatim\n *\n * This will also result in a \\c destroyed event being sent to all the\n * participants in the audio room, which will look like this:\n *\n\\verbatim\n{\n\t\"audiobridge\" : \"destroyed\",\n\t\"room\" : <unique numeric ID of the destroyed room>\n}\n\\endverbatim\n *\n * To enable or disable recording of mixed audio stream while the conference\n * is in progress, you can make use of the \\c enable_recording request,\n * which has to be formatted as follows:\n *\n\\verbatim\n{\n\t\"request\" : \"enable_recording\",\n\t\"room\" : <unique numeric ID of the room>,\n\t\"secret\" : \"<room secret; mandatory if configured>\"\n\t\"record\" : <true|false, whether this room should be automatically recorded or not>,\n\t\"record_file\" : \"<file where audio recording should be saved (optional)>\",\n\t\"record_dir\" : \"<path where audio recording file should be saved (optional)>\"\n}\n\\endverbatim\n *\n * A room can also be recorded by saving the individual contributions of\n * participants to separate MJR files instead, in a format compatible with\n * the \\ref recordings. While a recording for each participant can be\n * enabled or disabled separately, there also is a request to enable or\n * disable them in bulk, thus implementing a feature similar to \\c enable_recording\n * but for MJR files, rather than for a \\c .wav mix. This can be done using\n * the \\c enable_mjrs request, which has to be formatted as follows:\n *\n\\verbatim\n{\n\t\"request\" : \"enable_mjrs\",\n\t\"room\" : <unique numeric ID of the room>,\n\t\"secret\" : \"<room secret; mandatory if configured>\"\n\t\"mjrs\" : <true|false, whether all participants in the room should be individually recorded to mjr files or not>,\n\t\"mjrs_dir\" : \"<path where all MJR files should be saved to (optional)>\"\n}\n\\endverbatim\n *\n *\n * You can check whether a room exists using the \\c exists request,\n * which has to be formatted as follows:\n *\n\\verbatim\n{\n\t\"request\" : \"exists\",\n\t\"room\" : <unique numeric ID of the room to check>\n}\n\\endverbatim\n *\n * A successful request will result in a \\c success response:\n *\n\\verbatim\n{\n\t\"audiobridge\" : \"success\",\n\t\"room\" : <unique numeric ID>,\n\t\"exists\" : <true|false>\n}\n\\endverbatim\n *\n * You can configure whether to check tokens or add/remove people who can join\n * a room using the \\c allowed request, which has to be formatted as follows:\n *\n\\verbatim\n{\n\t\"request\" : \"allowed\",\n\t\"secret\" : \"<room secret, mandatory if configured>\",\n\t\"action\" : \"enable|disable|add|remove\",\n\t\"room\" : <unique numeric ID of the room to update>,\n\t\"allowed\" : [\n\t\t// Array of strings (tokens users might pass in \"join\", only for add|remove)\n\t]\n}\n\\endverbatim\n *\n * A successful request will result in a \\c success response:\n *\n\\verbatim\n{\n\t\"audiobridge\" : \"success\",\n\t\"room\" : <unique numeric ID>,\n\t\"allowed\" : [\n\t\t// Updated, complete, list of allowed tokens (only for enable|add|remove)\n\t]\n}\n\\endverbatim\n *\n * If you're the administrator of a room (that is, you created it and have access\n * to the secret) you can kick participants using the \\c kick request. Notice\n * that this only kicks the user out of the room, but does not prevent them from\n * re-joining: to ban them, you need to first remove them from the list of\n * authorized users (see \\c allowed request) and then \\c kick them. The \\c kick\n * request has to be formatted as follows:\n *\n\\verbatim\n{\n\t\"request\" : \"kick\",\n\t\"secret\" : \"<room secret, mandatory if configured>\",\n\t\"room\" : <unique numeric ID of the room>,\n\t\"id\" : <unique numeric ID of the participant to kick>\n}\n\\endverbatim\n *\n * A successful request will result in a \\c success response:\n *\n\\verbatim\n{\n\t\"audiobridge\" : \"success\",\n}\n\\endverbatim\n *\n * If you're the administrator of a room (that is, you created it and have access\n * to the secret) you can kick all participants using the \\c kick_all request. Notice\n * that this only kicks all users out of the room, but does not prevent them from\n * re-joining: to ban them, you need to first remove them from the list of\n * authorized users (see \\c allowed request) and then perform \\c kick_all.\n * The \\c kick_all request has to be formatted as follows:\n *\n\\verbatim\n{\n\t\"request\" : \"kick_all\",\n\t\"secret\" : \"<room secret, mandatory if configured>\",\n\t\"room\" : <unique numeric ID of the room>\n}\n\\endverbatim\n *\n * A successful request will result in a \\c success response:\n *\n\\verbatim\n{\n\t\"audiobridge\" : \"success\",\n}\n\\endverbatim\n *\n * Another option available for administrators is suspending participants:\n * in that case, participants are not kicked from the room (they remain\n * in), but their contribution is not added to the mix, and they don't\n * receive any audio from the mix either. This is a useful option to\n * temporarily detach a participant from the room (e.g., because they'll\n * be busy somewhere else) while still allowing them to keep the existing\n * PeerConnection up and running, so that it can be quickly restored\n * when they're back; since they're not part of the mix and don't receive\n * any audio, the CPU resources to manage them are reduced as well. By\n * default these suspended users participants will still receive events\n * related to changes in the room (e.g., participants joining and leaving,\n * mutes and unmutes, etc.), but these can be disabled too in case saving\n * unnecessary signalling is desired: in that case, a suspended participant\n * will only receive a recap of the current status when resumed.\n * The \\c suspend request must be formatted as follows:\n *\n *\n\\verbatim\n{\n\t\"request\" : \"suspend\",\n\t\"secret\" : \"<room secret, mandatory if configured>\",\n\t\"room\" : <unique numeric ID of the room>,\n\t\"id\" : <unique numeric ID of the participant to suspend>,\n\t\"pause_events\" : <whether room events should be paused while suspended;

Of course remember not to pass any JSEP-related payload when\n * doing a \\c changeroom as the same pre-existing PeerConnection will be\n * re-used for the purpose.\n *\n * Notice that you can also ask the AudioBridge plugin to send you an offer,\n * when you join, rather than providing one yourself: this means that the\n * SDP offer/answer roles would be reversed, and so you'd have to provide\n * an answer yourself in this case. Remember that, in case renegotiations\n * or restarts take place, they MUST follow the same negotiation pattern\n * as the one that originated the connection: it's an error to send an\n * SDP offer to the plugin to update a PeerConnection, if the plugin sent\n * you an offer originally. It's advised to let users generate the offer,\n * and let the plugin answer: this reverserd role is mostly here to\n * facilitate the setup of cascaded mixers, e.g., allow one AudioBridge\n * to connect to the other via WebRTC (which wouldn't be possible if\n * both expected an offer from the other). Refer to the \\ref aboffer\n * section for more details.\n *\n * About the syntax of all the above mentioned requests, \\c join has\n * to be formatted as follows:\n *\n\\verbatim\n{\n\t\"request\" : \"join\",\n\t\"room\" : <numeric ID of the room to join>,\n\t\"id\" : <unique ID to assign to the participant; optional, assigned by the plugin if missing>,\n\t\"group\" : \"<group to assign to this participant (for forwarding purposes only; optional, mandatory if enabled in the room)>\",\n\t\"pin\" : \"<password required to join the room, if any; optional>\",\n\t\"display\" : \"<display name to have in the room; optional>\",\n\t\"token\" : \"<invitation token, in case the room has an ACL; optional>\",\n\t\"muted\" : <true|false, whether to start unmuted or muted>,\n\t\"suspended\" : <true|false, whether to start suspended or not (false by default)>,\n\t\"pause_events\" : <whether room events should be paused, if the user is joining as suspended; optional, false by default>\n\t\"codec\" : \"<codec to use, among opus (default), pcma (A-Law) or pcmu (mu-Law)>\",\n\t\"bitrate\" : <bitrate to use for the Opus stream in bps; optional, default=0 (libopus decides)>,\n\t\"quality\" : <0-10, Opus-related complexity to use, the higher the value, the better the quality (but more CPU); optional, default is 4>,\n\t\"expected_loss\" : <0-20, a percentage of the expected loss (capped at 20%), only needed in case outgoing FEC is used; optional, default is 0 (FEC disabled even when negotiated) or the room default>,\n\t\"volume\" : <percent value, <100 reduces volume, >100 increases volume; optional, default is 100 (no volume change)>,\n\t\"spatial_position\" : <in case spatial audio is enabled for the room, panning of this participant (0=left, 50=center, 100=right)>,\n\t\"denoise\" : <true|false, whether denoising via RNNoise should be performed for this participant (default=room value)>,\n\t\"secret\" : \"<room management password; optional, if provided the user is an admin and can't be globally muted with mute_room>\",\n\t\"audio_level_average\" : \"<if provided, overrides the room audio_level_average for this user; optional>\",\n\t\"audio_active_packets\" : \"<if provided, overrides the room audio_active_packets for this user; optional>\",\n\t\"record\": <true|false, whether to record this user's contribution to a .mjr file (mixer not involved)>,\n\t\"filename\": \"<basename of the file to record to, -audio.mjr will be added by the plugin; will be relative to mjrs_dir, if configured in the room>\"\n}\n\\endverbatim\n *\n * A successful request will produce a \\c joined event:\n *\n\\verbatim\n{\n\t\"audiobridge\" : \"joined\",\n\t\"room\" : <numeric ID of the room>,\n\t\"id\" : <unique ID assigned to the participant>,\n\t\"display\" : \"<display name of the new participant>\",\n\t\"participants\" : [\n\t\t// Array of existing participants in the room\n\t]\n}\n\\endverbatim\n *\n * The other participants in the room will be notified about the new\n * participant by means of a different \\c joined event, which will only\n * include the \\c room and the new participant as the only object in\n * a \\c participants array.\n *\n * Notice that, while the AudioBridge assumes participants will exchange\n * media via WebRTC, there's a less known feature that allows you to use\n * plain RTP to join an AudioBridge room instead.

A JSEP answer will\n * be sent back along the result of the request, if successful.\n *\n * \\subsection aboffer AudioBridge-generated offers\n *\n * As anticipated in the previous sections, by default the AudioBridge\n * plugin expects an SDP offer from users interested to join a room, and\n * generates an SDP answer to complete the WebRTC negotiation process:\n * this SDP offer can be provided either in a \\c join request or a\n * \\c configure one, depending on how the app is constructed.\n *\n * It's worth pointing out that the AudioBridge plugin also supports\n * reversed roles when it comes to negotiation: that is, a user can ask\n * the plugin to generate an SDP offer first, to which they'd provide\n * an SDP answer to. This slightly changes the way the negotiation works\n * within the context of the AudioBridge API, as some messages may have\n * to be used in a different way. More specifically, if a user wants the\n * plugin to generate an offer, they'll have to include a:\n *\n\\verbatim\n\t[..]\n\t\"generate_offer\" : true,\n\t[..]\n}\n\\endverbatim\n *\n * property in the \\c join or \\c configure request used to setup the\n * PeerConnection. This means that the user will receive a JSEP SDP\n * offer as part of the related event: at this point, the user needs\n * to prepare to send a JSEP SDP answer and send it back to the plugin\n * to complete the negotiation. The user must use the \\c configure\n * request to provide this SDP answer: no need to provide additional\n * attributes in the request, unless it's needed for application related\n * purposes (e.g., to start muted).\n *\n * Notice that this does have an impact on renegotiations, e.g., for\n * ICE restarts or changes in the media direction. As a policy, plugins\n * in Janus tend to enforce the same negotiation pattern used to setup\n * the PeerConnection initially for renegotiations too, as it reduces\n * the risk of issues like glare: this means that users will NOT be able\n * to send an SDP offer to the AudioBridge plugin to update an existing\n * PeerConnection, if that PeerConnection had previously been originated\n * by a plugin offer instead. The plugin will treat this as an error.\n *\n * The \\c generate_offer feature also works for plain RTP participants.\n * If you want to use them in that context (e.g., because you want to\n * first obtain the AudioBridge's RTP details to craft a SIP INVITE,\n * and only later provide the remote RTP details back to the plugin),\n * set the \\c generate_offer property to \\c true and pass an \\c rtp\n * object without \\c ip and \\c port (an empty \\c rtp object will work\n * too). This will instruct the plugin to return its own connectivity\n * information first. When you are aware of the connectivity information\n * for the participant side (e.g., because you got a SIP 200 OK back),\n * pass a new \\c rtp object with \\c ip and \\c port in a \\c configure\n * request on the participant handle, which will finalize the media\n * establishment.\n *\n */\n\n#include \"plugin.h\"\n#ifdef __FreeBSD__\n#include <sys/socket.h>\n#include

While the plugin implements low level stuff like media\n * manipulation, routing, recording, etc., all the logic is demanded\n * to an external JavaScript script. This means that the C code exposes functions\n * to the JavaScript script (e.g., to dictate what to do with media, whether\n * recording should be done, sending PLIs, etc.), while JavaScript exposes\n * functions to be notified by the C code about important events (e.g.,\n * new users, WebRTC state, incoming messages, etc.).\n *\n * Considering the C code and the JavaScript script will need some sort of\n * \"contract\" in order to be able to properly interact with each other,\n * the interface (as in method names) must be consistent, but the logic\n * in the JavaScript script can be completely customized, so that it fits\n * whatever requirement one has (e.g., something like the EchoTest, or\n * something like the VideoRoom).\n *\n * \\section jsapi JavaScript interfaces\n *\n * Every JavaScript script that wants to implement a Janus plugin must provide\n * the following functions as callbacks:\n *\n * - \\c init(): called when janus_duktape.c is initialized;\n * - \\c destroy(): called when janus_duktape.c is deinitialized (Janus shutting down);\n * - \\c createSession(): called when a new user attaches to the Janus Duktape plugin;\n * - \\c destroySession(): called when an attached user detaches from the Janus Duktape plugin;\n * - \\c querySession(): called when an Admin API query for a specific user gets to the Janus Duktape plugin;\n * - \\c handleMessage(): called when a user sends a message to the Janus Duktape plugin;\n * - \\c setupMedia(): called when a users's WebRTC PeerConnection goes up;\n * - \\c hangupMedia(): called when a users's WebRTC PeerConnection goes down;\n * - \\c resumeScheduler(): called by the C scheduler to resume coroutines.\n *\n * While \\c init() expects a path to a config file (which you can ignore if\n * unneeded), and \\c destroy() and \\c resumeScheduler() don't need any\n * argument, all other functions expect at the very least a numeric session\n * identifier, that will uniquely address a user in the plugin. Such a\n * value is created dynamically by the C code, and so all the JavaScript script\n * needs to do is track it as a unique session identifier when handling\n * requests and pushing responses/events/actions towards the C code.\n * Refer to the existing examples (e.g., \\c echotest.js) to see the\n * exact signature for all the above callbacks.\n *\n * \\note Notice that, along the above mentioned callbacks, JavaScript scripts\n * can also implement functions like \\c incomingRtp() \\c incomingRtcp()\n * \\c incomingTextData() and \\c incomingBinaryData() to handle those packets\n * directly, instead of letting the C code worry about relaying/processing\n * them. While it might make sense to handle incoming data channel messages\n * with \\c incomingTextData() or \\c incomingBinaryData\n * though, the performance impact of directly processing and manipulating\n * RTP an RTCP packets is probably too high, and so their usage is currently\n * discouraged. The \\c dataReady() callback can be used to figure out when\n * data can be sent. As an additional note, JavaScript scripts can also decide to\n * implement the functions that return information about the plugin itself,\n * namely \\c getVersion() \\c getVersionString() \\c getDescription()\n * \\c getName() \\c getAuthor() and \\c getPackage(). If not implemented,\n * the JavaScript plugin will return its own info (i.e., \"janus.plugin.javascript\", etc.).\n * Most of the times, JavaScript scripts will not need to override this information,\n * unless they really want to register their own name spaces and versioning.\n * JavaScript scripts can also receive information on slow links via the\n * \\c slowLink() callback, in order to react accordingly: e.g., reduce\n * the bitrate of a video sender if they, or their viewers, are experiencing\n * issues. Finally, in case simulcast is used, JavaScript scripts may\n * receive events on substream and/or temporal layer changes happening\n * for receiving sessions via the \\c substreamChanged() and the\n * \\c temporalLayerChanged() callbacks: this may be useful to track\n * which layer is actually being sent, vs. what was requested.\n *\n * \\section dtcapi C interfaces\n *\n * Just as the JavaScript script needs to expose callbacks that the C code can\n * invoke, the C code exposes methods as JavaScript functions accessible from\n * the JavaScript script. This includes means to push events, configure how\n * media should be routed without handling each packet in JavaScript, sending\n * RTCP feedback, start/stop recording and so on.\n *\n * The following are the functions the C code exposes:\n *\n * - \\c pushEvent(): push an event to the user via Janus API;\n * - \\c eventsIsEnabled(): check if Event Handlers are enabled in the core;\n * - \\c notifyEvent(): send an event to Event Handlers;\n * - \\c closePc(): force the closure of a PeerConnection;\n * - \\c configureMedium(): specify whether audio/video/data can be received/sent;\n * - \\c addRecipient(): specify which user should receive a user's media;\n * - \\c removeRecipient(): specify which user should not receive a user's media anymore;\n * - \\c setBitrate(): specify the bitrate to force on a user via REMB feedback;\n * - \\c setPliFreq(): specify how often the plugin should send a PLI to this user;\n * - \\c setSubstream(): set the target simulcast substream;\n * - \\c setTemporalLayer(): set the target simulcast temporal layer;\n * - \\c sendPli(): send a PLI (keyframe request);\n * - \\c startRecording(): start recording audio, video and or data for a user;\n * - \\c stopRecording(): start recording audio, video and or data for a user;\n * - \\c pokeScheduler(): notify the C code that there's a coroutine to resume;\n * - \\c timeCallback(): trigger the execution of a JavaScript function after X milliseconds.\n *\n * As anticipated in the previous section, almost all these methods also\n * expect the unique session identifier to address a specific user in the\n * plugin. This is true for all the above methods expect \\c eventsIsEnabled\n * and, more importantly, both \\c timeCallback() and \\c pokeScheduler() which,\n * together with JavaScript's \\c resumeScheduler(), will be clearer in the next section.\n *\n * \\section jcoroutines JavaScript/C coroutines scheduler\n *\n * Duktape is a single threaded environment. While it has a concept similar\n * to threads called coroutines, these are not threads as known in C.\n * In order to allow for an easy to implement asynchronous behaviour in\n * JavaScript scripts, you can leverage a scheduler implemented in the C code.\n *\n * More specifically, when the plugin starts a dedicated thread is devoted\n * to the only purpose of acting as a scheduler for JavaScript coroutines. This\n * means that, whenever this C scheduler is awaken, it will call the\n * \\c resumeScheduler() function in the JavaScript script, thus allowing the\n * JavaScript script to execute one or more pending coroutines. The C scheduler\n * only acts when triggered, which means it's up to the JavaScript script to\n * tell it when to wake up: this is possible via the \\c pokeScheduler()\n * function, which does nothing more than sending a simple signal to the\n * C scheduler to wake it up. As such, it's easy for the JavaScript script to\n * implement asynchronous behaviour, e.g.:\n *\n * 1. JavaScript script needs to do something asynchronously;\n * 2. JavaScript script creates coroutine, and takes note of it somewhere;\n * 3. JavaScript script calls \\c pokeScheduler();\n * 4. C code sends signal to the thread acting as a scheduler;\n * 5. when the scheduling thread wakes up, it calls \\c resumeScheduler();\n * 6. JavaScript script resumes the previously queued coroutine.\n *\n * This simple mechanism is what the sample JavaScript scripts provided in this\n * repo use, for instance, to handle incoming messages asynchronously,\n * so you can refer to those to have an idea of how it can be used. The\n * next section will address \\ref jtimers instead.\n *\n * \\note You can implement asynchronous behaviour any way you want, and\n * you're not required to use this C scheduler. Anyway, you must implement\n * a method called \\c resumeScheduler() anyway, as the C code checks for\n * its presence and fails if it's not there. If you don't need it, just\n * create an empty function that does nothing and you'll be fine.\n *\n * \\section jtimers JavaScript/C time-based scheduler\n *\n * Another helpful way to implement asynchronous behaviour is with the\n * help of the \\c timeCallback() function. Specifically, this function\n * implements a mechanism to ask for a specific JavaScript method to be invoked\n * after a provided amount of time. To specify the function to invoke,\n * an optional argument to pass (which MUST be a string) and the time to\n * wait to do that. This is particularly helpful when you're handling\n * asynchronous behaviour that you want to inspect on a regular basis.\n *\n * The \\c timeCallback() function expects three arguments:\n *\n * \\verbatim\ntimeCallback(function, argument, milliseconds);\n\\endverbatim\n *\n * The only mandatory parameter is \\c function: if you set \\c argument\n * to \\c null no argument will be passed to \\c function when it's executed;\n * it \\c milliseconds is 0, \\c function will be executed as soon as possible.\n *\n * \\verbatim\n// This will cause an error (timeCallback needs a function)\ntimeCallback();\n// Invoke test() in 500 milliseconds\ntimeCallback(\"test\", null, 500);\n// Invoke test(\"ciccio\") in 2 seconds\ntimeCallback(\"test\", \"ciccio\", 2000);\n\\endverbatim\n *\n * Notice that \\c timeCallback() allows you to formally recreate the\n * mechanism \\c pokeScheduler() and \\c resumeScheduler() implement, as\n * the following is pretty much an equivalent of that:\n *\n * \\verbatim\ntimeCallback(\"resumeScheduler\", null, 0);\n\\endverbatim\n *\n * Anyway, \\c pokeScheduler() and \\c resumeScheduler() is much more\n * compact and less verbose, and as such is preferred in cases where\n * timing and opaque arguments are not needed.\n *\n * Refer to the \\ref jspapi section for more information on how you\n * can register your own C functions.\n */\n\n#include <jansson.h>\n\n/* Session definition and hashtable */\n#include \"janus_duktape_data.h\"\n/* Extra/custom C hooks and code */\n#include

plugin.\n * For this to work, though, the janus_duktape_session object and its\n * indexing in the hashtable need to be defined externally, which is\n * what this file is for.\n *\n * Notice that all the management associated to sessions (creating or\n * destroying sessions, locking their global mutex, updating the\n * hashtable) is done in the core of the JavaScript plugin: here we only\n * define them, so that they can be accessed/used by the extra code too.\n *\n * \\ingroup jspapi\n * \\ref jspapi\n */\n\n#ifndef JANUS_DUKTAPE_DATA_H\n#define JANUS_DUKTAPE_DATA_H\n\n#include

A peer attaching to this plugin will\n * receive back the same RTP packets and RTCP messages he sends: the\n * RTCP messages, of course, would be modified on the way by the Janus core\n * to make sure they are coherent with the involved SSRCs. In order to\n * demonstrate how peer-provided messages can change the behaviour of a\n * plugin, this plugin implements a simple API based on three messages:\n *\n * 1. a message to enable/disable audio (that is, to tell the plugin\n * whether incoming audio RTP packets need to be sent back or discarded);\n * 2. a message to enable/disable video (that is, to tell the plugin\n * whether incoming video RTP packets need to be sent back or discarded);\n * 3. a message to cap the bitrate (which would modify incoming RTCP\n * REMB messages before sending them back, in order to trick the peer into\n * thinking the available bandwidth is different).\n *\n * \\section echoapi Echo Test API\n *\n * There's a single unnamed request you can send and it's asynchronous,\n * which means all responses (successes and errors) will be delivered\n * as events with the same transaction.\n *\n * The request has to be formatted as follows. All the attributes are\n * optional, so any request can contain a subset of them:\n *\n\\verbatim\n{\n\t\"audio\" : true|false,\n\t\"audiocodec\" : \"<optional codec name; only used when creating a PeerConnection>\",\n\t\"video\" : true|false,\n\t\"videocodec\" : \"<optional codec name; only used when creating a PeerConnection>\",\n\t\"videoprofile\" : \"<optional codec profile to force; only used when creating a PeerConnection, only valid for VP9 (0 or 2) and H.264 (e.g., 42e01f)>\",\n\t\"bitrate\" : <numeric bitrate value>,\n\t\"record\" : true|false,\n\t\"filename\" : <base path/filename to use for the recording>,\n\t\"substream\" : <substream to receive (0-2), in case simulcasting is enabled>,\n\t\"temporal\" : <temporal layers to receive (0-2), in case simulcasting is enabled>,\n\t\"svc\" : true|false,\n\t\"spatial_layer\" : <spatial layer to receive (0-2), in case SVC is enabled>,\n\t\"temporal_layer\" : <temporal layers to receive (0-2), in case SVC is enabled>\n}\n\\endverbatim\n *\n * When negotiating a new PeerConnection, by default the EchoTest tries to\n * use the preferred audio codecs as set by the user; if for any reason you\n * want to override what the browsers offered first and use a different\n * codec instead (e.g., to try VP9 instead of VP8), you can use the\n * \\c audiocodec property for audio, and \\c videocodec for video. For video\n * codecs supporting a specific profile negotiation (VP9 and H.264), you can\n * specify which profile you're interested in using the \\c videoprofile property.\n *\n * All the other settings can be applied dynamically during the session:\n * \\c audio instructs the plugin to do or do not bounce back audio\n * frames; \\c video does the same for video; \\c bitrate caps the\n * bandwidth to force on the browser encoding side (e.g., 128000 for\n * 128kbps); \\c record enables or disables the recording of this peer;\n * in case recording is enabled, \\c filename allows to specify a base\n * path/filename to use for the files (-audio.mjr, -video.mjr and -data.mjr\n * are automatically appended); finally, in case the session uses\n * simulcasting, \\c substream and \\c temporal can be used to manually\n * pick which substream and/or temporal layer should be received back,\n * while \\c spatial_layer and \\c temporal_layer provide the same\n * functionality but within the context of SVC.\n *\n * A JSEP offer can be sent along any request to negotiate a PeerConnection:\n * in that case, a JSEP answer will be provided with the asynchronous\n * response notification. Other requests (e.g., to dynamically manipulate\n * the bitrate while testing) have to be sent without any JSEP payload\n * attached, unless you want to renegotiate a session (e.g., to add/remove\n * a media stream, or force an ICE restart): in case of renegotiations,\n * the same rules as the first JSEP offer apply.\n *\n * A successful request will result in an \\c ok event:\n *\n\\verbatim\n{\n\t\"echotest\" : \"event\",\n\t\"result\": \"ok\"\n}\n\\endverbatim\n *\n * An error instead will provide both an error code and a more verbose\n * description of the cause of the issue:\n *\n\\verbatim\n{\n\t\"echotest\" : \"event\",\n\t\"error_code\" : <numeric ID, check Macros below>,\n\t\"error\" : \"<error description as a string>\"\n}\n\\endverbatim\n *\n * If the plugin detects a loss of the associated PeerConnection, a\n * \"done\" notification is triggered to inform the application the Echo\n * Test session is over:\n *\n\\verbatim\n{\n\t\"echotest\" : \"event\",\n\t\"result\": \"done\"\n}\n\\endverbatim\n */\n\n#include \"plugin.h\"\n\n#include <jansson.h>\n\n#include \"../debug.h\"\n#include \"../apierror.h\"\n#include \"../config.h\"\n#include

While the plugin implements low level stuff like media\n * manipulation, routing, recording, etc., all the logic is demanded\n * to an external Lua script. This means that the C code exposes functions\n * to the Lua script (e.g., to dictate what to do with media, whether\n * recording should be done, sending PLIs, etc.), while Lua exposes\n * functions to be notified by the C code about important events (e.g.,\n * new users, WebRTC state, incoming messages, etc.).\n *\n * Considering the C code and the Lua script will need some sort of\n * \"contract\" in order to be able to properly interact with each other,\n * the interface (as in method names) must be consistent, but the logic\n * in the Lua script can be completely customized, so that it fits\n * whatever requirement one has (e.g., something like the EchoTest, or\n * something like the VideoRoom).\n *\n * \\section luaapi Lua interfaces\n *\n * Every Lua script that wants to implement a Janus plugin must provide\n * the following functions as callbacks:\n *\n * - \\c init(): called when janus_lua.c is initialized;\n * - \\c destroy(): called when janus_lua.c is deinitialized (Janus shutting down);\n * - \\c createSession(): called when a new user attaches to the Janus Lua plugin;\n * - \\c destroySession(): called when an attached user detaches from the Janus Lua plugin;\n * - \\c querySession(): called when an Admin API query for a specific user gets to the Janus Lua plugin;\n * - \\c handleMessage(): called when a user sends a message to the Janus Lua plugin;\n * - \\c setupMedia(): called when a users's WebRTC PeerConnection goes up;\n * - \\c hangupMedia(): called when a users's WebRTC PeerConnection goes down;\n * - \\c resumeScheduler(): called by the C scheduler to resume coroutines.\n *\n * While \\c init() expects a path to a config file (which you can ignore if\n * unneeded), and \\c destroy() and \\c resumeScheduler() don't need any\n * argument, all other functions expect at the very least a numeric session\n * identifier, that will uniquely address a user in the plugin. Such a\n * value is created dynamically by the C code, and so all the Lua script\n * needs to do is track it as a unique session identifier when handling\n * requests and pushing responses/events/actions towards the C code.\n * Refer to the existing examples (e.g., \\c echotest.lua) to see the\n * exact signature for all the above callbacks.\n *\n * \\note Notice that, along the above mentioned callbacks, Lua scripts\n * can also implement functions like \\c incomingRtp() \\c incomingRtcp()\n * \\c incomingTextData() and \\c incomingBinaryData() to handle those packets\n * directly, instead of letting the C code worry about relaying/processing\n * them. While it might make sense to handle incoming data channel messages\n * with \\c incomingTextData() or \\c incomingBinaryData\n * though, the performance impact of directly processing and manipulating\n * RTP an RTCP packets is probably too high, and so their usage is currently\n * discouraged. The \\c dataReady() callback can be used to figure out when\n * data can be sent. As an additional note, Lua scripts can also decide to\n * implement the functions that return information about the plugin itself,\n * namely \\c getVersion() \\c getVersionString() \\c getDescription()\n * \\c getName() \\c getAuthor() and \\c getPackage(). If not implemented,\n * the Lua plugin will return its own info (i.e., \"janus.plugin.lua\", etc.).\n * Most of the times, Lua scripts will not need to override this information,\n * unless they really want to register their own name spaces and versioning.\n * Lua scripts can also receive information on slow links via the\n * \\c slowLink() callback, in order to react accordingly: e.g., reduce\n * the bitrate of a video sender if they, or their viewers, are experiencing\n * issues. Finally, in case simulcast is used, Lia scripts may receive\n * events on substream and/or temporal layer changes happening for\n * receiving sessions via the \\c substreamChanged() and the\n * \\c temporalLayerChanged() callbacks: this may be useful to track\n * which layer is actually being sent, vs. what was requested.\n *\n * \\section capi C interfaces\n *\n * Just as the Lua script needs to expose callbacks that the C code can\n * invoke, the C code exposes methods as Lua functions accessible from\n * the Lua script. This includes means to push events, configure how\n * media should be routed without handling each packet in Lua, sending\n * RTCP feedback, start/stop recording and so on.\n *\n * The following are the functions the C code exposes:\n *\n * - \\c pushEvent(): push an event to the user via Janus API;\n * - \\c eventsIsEnabled(): check if Event Handlers are enabled in the core;\n * - \\c notifyEvent(): send an event to Event Handlers;\n * - \\c closePc(): force the closure of a PeerConnection;\n * - \\c endSession(): force the detach of a plugin handle;\n * - \\c configureMedium(): specify whether audio/video/data can be received/sent;\n * - \\c addRecipient(): specify which user should receive a user's media;\n * - \\c removeRecipient(): specify which user should not receive a user's media anymore;\n * - \\c setBitrate(): specify the bitrate to force on a user via REMB feedback;\n * - \\c setPliFreq(): specify how often the plugin should send a PLI to this user;\n * - \\c setSubstream(): set the target simulcast substream;\n * - \\c setTemporalLayer(): set the target simulcast temporal layer;\n * - \\c sendPli(): send a PLI (keyframe request);\n * - \\c startRecording(): start recording audio, video and or data for a user;\n * - \\c stopRecording(): start recording audio, video and or data for a user;\n * - \\c pokeScheduler(): notify the C code that there's a coroutine to resume;\n * - \\c timeCallback(): trigger the execution of a Lua function after X milliseconds.\n *\n * As anticipated in the previous section, almost all these methods also\n * expect the unique session identifier to address a specific user in the\n * plugin. This is true for all the above methods expect \\c eventsIsEnabled\n * and, more importantly, both \\c timeCallback() and \\c pokeScheduler() which,\n * together with Lua's \\c resumeScheduler(), will be clearer in the next section.\n *\n * \\section coroutines Lua/C coroutines scheduler\n *\n * Lua is a single threaded environment. While it has a concept similar\n * to threads called coroutines, these are not threads as known in C.\n * In order to allow for an easy to implement asynchronous behaviour in\n * Lua scripts, you can leverage a scheduler implemented in the C code.\n *\n * More specifically, when the plugin starts a dedicated thread is devoted\n * to the only purpose of acting as a scheduler for Lua coroutines. This\n * means that, whenever this C scheduler is awaken, it will call the\n * \\c resumeScheduler() function in the Lua script, thus allowing the\n * Lua script to execute one or more pending coroutines. The C scheduler\n * only acts when triggered, which means it's up to the Lua script to\n * tell it when to wake up: this is possible via the \\c pokeScheduler()\n * function, which does nothing more than sending a simple signal to the\n * C scheduler to wake it up. As such, it's easy for the Lua script to\n * implement asynchronous behaviour, e.g.:\n *\n * 1. Lua script needs to do something asynchronously;\n * 2. Lua script creates coroutine, and takes note of it somewhere;\n * 3. Lua script calls \\c pokeScheduler();\n * 4. C code sends signal to the thread acting as a scheduler;\n * 5. when the scheduling thread wakes up, it calls \\c resumeScheduler();\n * 6. Lua script resumes the previously queued coroutine.\n *\n * This simple mechanism is what the sample Lua scripts provided in this\n * repo use, for instance, to handle incoming messages asynchronously,\n * so you can refer to those to have an idea of how it can be used. The\n * next section will address \\ref timers instead.\n *\n * \\note You can implement asynchronous behaviour any way you want, and\n * you're not required to use this C scheduler. Anyway, you must implement\n * a method called \\c resumeScheduler() anyway, as the C code checks for\n * its presence and fails if it's not there. If you don't need it, just\n * create an empty function that does nothing and you'll be fine.\n *\n * \\section timers Lua/C time-based scheduler\n *\n * Another helpful way to implement asynchronous behaviour is with the\n * help of the \\c timeCallback() function. Specifically, this function\n * implements a mechanism to ask for a specific Lua method to be invoked\n * after a provided amount of time. To specify the function to invoke,\n * an optional argument to pass (which MUST be a string) and the time to\n * wait to do that. This is particularly helpful when you're handling\n * asynchronous behaviour that you want to inspect on a regular basis.\n *\n * The \\c timeCallback() function expects three arguments:\n *\n * \\verbatim\ntimeCallback(function, argument, milliseconds)\n\\endverbatim\n *\n * The only mandatory parameter is \\c function: if you set \\c argument\n * to \\c nil no argument will be passed to \\c function when it's executed;\n * it \\c milliseconds is 0, \\c function will be executed as soon as possible.\n *\n * \\verbatim\n-- This will cause an error (timeCallback needs three arguments)\ntimeCallback()\n-- Invoke test() in 500 milliseconds\ntimeCallback(\"test\", nil, 500)\n-- Invoke test(\"ciccio\") in 2 seconds\ntimeCallback(\"test\", \"ciccio\", 2000)\n\\endverbatim\n *\n * Notice that \\c timeCallback() allows you to formally recreate the\n * mechanism \\c pokeScheduler() and \\c resumeScheduler() implement, as\n * the following is pretty much an equivalent of that:\n *\n * \\verbatim\ntimeCallback(\"resumeScheduler\", nil, 0)\n\\endverbatim\n *\n * Anyway, \\c pokeScheduler() and \\c resumeScheduler() is much more\n * compact and less verbose, and as such is preferred in cases where\n * timing and opaque arguments are not needed.\n *\n * Refer to the \\ref luapapi section for more information on how you\n * can register your own C functions.\n

It is named \"NoSIP\" since, as the name suggests, signalling\n * takes no place here, and is entirely up to the application. The typical\n * usage of this application is something like this:\n *\n * 1. a WebRTC application handles signalling on its own (e.g., SIP), but\n * needs to interact with a peer that doesn't support WebRTC (DTLS/ICE);\n * 2. it creates a handle with the NoSIP plugin, creates a JSEP SDP offer,\n * and passes it to the plugin;\n * 3. the plugin creates a barebone SDP that can be used to communicate\n * with the legacy peer, binds to the ports for RTP/RTCP, and sends this\n * plain SDP back to the application;\n * 4. the application uses this barebone SDP in its signalling, and expects\n * an answer from the peer;\n * 5. the SDP answer from the peer will be barebone as well, and so unfit\n * for WebRTC usage; as such, the application passes it to the plugin as\n * the answer to match the offer created before;\n * 6. the plugin matches the answer to the offer, and starts exchanging\n * RTP/RTCP with the legacy peer: media coming from the peer is relayed\n * via WebRTC to the application, and WebRTC stuff coming from the application\n * is relayed via plain RTP/RTCP to the legacy peer.\n *\n * The same behaviour can be followed if the application is the callee\n * instead, with the only difference being that the barebone offer will\n * come from the peer in this case, and the application will ask the\n * NoSIP plugin for a barebone answer instead.\n *\n * As you can see, the behaviour is pretty much the same as the SIP plugin,\n * with the key difference being that in this case there's no SIP stack in\n * the plugin itself. All signalling is left to the application, and Janus\n * (via the NoSIP plugin) is only responsible for bridging the media. This\n * might be more appropriate than the SIP plugin in cases where developers\n * want to keep control on the signalling layer, while still involving a\n * server of sorts. Of course, SIP is just an example here: other signalling\n * protocols may be involved as well (e.g., IAX, XMPP, others). The NoSIP\n * plugin, though, will generate and expect plain SDP, so you'll need to\n * take care of any adaptation that may be needed to make this work with\n * the signalling protocol of your choice.\n *\n * \\section nosipapi NoSIP Plugin API\n *\n * The plugin mainly supports two requests, \\c generate and \\c process,\n * which are both asynchronous. The \\c generate request take a JSEP offer\n * or answer, and generates a barebone SDP the \"legacy\" application can\n * use; the \\c process request, on the other hand, processes a remote\n * barebone SDP, and matches it to the plugin may have generated before,\n * in order to then return a JSEP offer or answer that can be used to\n * setup a PeerConnection.\n *\n * The \\c generate request must be formatted as follows:\n *\n\\verbatim\n{\n\t\"request\" : \"generate\",\n\t\"info\" : \"<opaque string that the user can provide for context; optional>\",\n\t\"srtp\" : \"<whether to mandate (sdes_mandatory) or offer (sdes_optional) SRTP support; optional>\",\n\t\"srtp_profile\" : \"<SRTP profile to negotiate, in case SRTP is offered; optional>\"\n}\n\\endverbatim\n *\n * As anticipated, this requires a JSEP offer or answer passed via Janus\n * API as part of a WebRTC PeerConnection negotiation. If the conversion\n * of the WebRTC JSEP SDP to barebone SDP is successful, a \\c generated\n * event is sent back to the user:\n *\n\\verbatim\n{\n\t\"nosip\" : \"event\",\n\t\"result\" : {\n\t\t\"event\" : \"generated\",\n\t\t\"type\" : \"<offer|answer, depending on the nature of the provided JSEP>\",\n\t\t\"sdp\" : \"<barebone SDP content>\",\n\t\t\"unique_id\" : \"<unique UUID of this session in this plugin, needed for some requests>\n\t}\n}\n\\endverbatim\n *\n * The \\c process request, instead, must be formatted as follows:\n *\n\\verbatim\n{\n\t\"request\" : \"process\",\n\t\"type\" : \"<offer|answer, depending on the nature of the provided SDP>\",\n\t\"sdp\" : \"<barebone SDP to convert>\"\n\t\"info\" : \"<opaque string that the user can provide for context; optional>\",\n\t\"srtp\" : \"<whether to mandate (sdes_mandatory) or offer (sdes_optional) SRTP support; optional>\",\n\t\"srtp_profile\" : \"<SRTP profile to negotiate, in case SRTP is offered; optional>\"\n}\n\\endverbatim\n *\n * As anticipated, this requires a \"legacy\" SDP offer or answer passed via\n * NoSIP plugin messaging, which is why the caller must specify if it's an\n * offer or answer. If the request is successful, a \\c processed event is\n * sent back to the user, along to the JSEP offer or answer that Janus\n * generated out of the barebone SDP:\n *\n\\verbatim\n{\n\t\"nosip\" : \"event\",\n\t\"result\" : {\n\t\t\"event\" : \"processed\",\n\t\t\"srtp\" : \"<whether the barebone SDP mandates (sdes_mandatory) or offers (sdes_optional) SRTP support; optional>\",\n\t\t\"unique_id\" : \"<unique UUID of this session in this plugin, needed for some requests>\n\t}\n}\n\\endverbatim\n *\n * To close a session you can use the \\c hangup request, which needs no\n * additional arguments, as the whole context can be extracted from the\n * current state of the session in the plugin:\n *\n\\verbatim\n{\n\t\"request\" : \"hangup\"\n}\n\\endverbatim\n *\n * An \\c hangingup event will be sent back, as this is an asynchronous request.\n *\n * As to other features, just as in the SIP plugin, the multimedia session\n * can be recorded. Considering the NoSIP plugin also assumes two peers\n * are in a call with each other (although it makes no assumptions on\n * the signalling that ties them together), it works exactly the same\n * way as the SIP plugin dooes when it comes to recording.\n * Specifically, you make use of the \\c recording request to either start\n * or stop a recording, using the following syntax:\n *\n\\verbatim\n{\n\t\"request\" : \"recording\",\n\t\"action\" : \"<start|stop, depending on whether you want to start or stop recording something>\"\n\t\"audio\" : <true|false; whether or not our audio should be recorded>,\n\t\"video\" : <true|false; whether or not our video should be recorded>,\n\t\"peer_audio\" : <true|false; whether or not our peer's audio should be recorded>,\n\t\"peer_video\" : <true|false; whether or not our peer's video should be recorded>,\n\t\"filename\" : \"<base path/filename to use for all the recordings>\"\n}\n\\endverbatim\n *\n * As you can see, this means that the two sides of conversation are recorded\n * separately, and so are the audio and video streams if available. You can\n * choose which ones to record, in case you're interested in just a subset.\n * The \\c filename part is just a prefix, and dictates the actual filenames\n * that will be used for the up-to-four recordings that may need to be enabled.\n *\n * A \\c recordingupdated event is sent back in case the request is successful.\n *\n * To programmatically send a video keyframe request to either the WebRTC user\n * or the SIP peer (or both), the \\c keyframe request can be used. This\n * request is particularly useful when the SIP peer doesn't support RTCP PLI,\n * and so may use other mechanisms (e.g., via signalling) to ask for a keyframe\n * to get video working. By using this request, the WebRTC user can ask Janus\n * to originate a PLI programmatically. The direction of the keyframe request\n * can be provided by using the \\c user and \\c peer properties: if \\c user\n * is \\c TRUE a keyframe request will be sent by Janus to the WebRTC user;\n * if \\c peer is \\c TRUE a keyframe request will be sent by Janus to the\n * SIP peer. In both cases an RTCP PLI message will be sent. The syntax of\n * the message is the following:\n *\n\\verbatim\n{\n\t\"request\" : \"keyframe\",\n\t\"user\" : <true|false; whether or not to send a keyframe request to the WebRTC user>,\n\t\"peer\" : <true|false; whether or not to send a keyframe request to the SIP peer>\n}\n\\endverbatim\n *\n * A \\c keyframesent event is sent back in case the request is successful.\n *\n * \\subsection nosiprtpfwd RTP forwarders in the NoSIP plugin\n *\n * RTP forwarders are a quite useful functionality that a few plugins\n * in Janus can take advantage of. As the name suggests, their main\n * purpose is indeed forwarding/relaying RTP traffic to an external\n * backend, for further processing or management of media packets outside\n * of the context of the plugin that's responsible for it.\n *\n * Within the context of the NoSIP plugin, RTP forwarders allow you to\n * send the RTP traffic belonging to a specific call to an external\n * backend, e.g., to a component implementing transcriptions, a remote\n * recorder, a lawful interception application or whatever else may have\n * a need for the content of a call in real-time. The RTP forwarder\n * functionality is conceived in a way that allows you to separately\n * forward individual RTP streams: this allows you to only forward, e.g.,\n * the audio packets of the local Janus user, only forward the video\n * packets of the peer, forward everything, or any combination in\n * between. For every media stream you're interested in forwarding, a\n * separate RTP forwarder will be needed, which is what enables this\n * flexibility. Multiple forwarders can be created for the same stream,\n * in case the same RTP traffic should be sent to multiple backends at\n * the same time.\n *\n * Notice that no signalling protocol is used for RTP forwarders. RTP traffic\n * is relayed out of context, using a specific API that is part of the\n * NoSIP plugin itself. RTP forwarders will need an ongoing call to\n * operate, though, as they'll be associated to existing media streams\n * in an existing call; more specifically, forwarding requests must\n * be performed on the handle that's handling the call that should be\n * the target of its operations, which is why the related requests don't\n * need any identifier (the scope is automatically obtained from the\n * context of the handle). Forwarders that were created while a call\n * was active will automatically be destroyed when the call is hung up\n *\n * To setup new RTP forwarders, you can use the \\c rtp_forward request,\n * which must be formatted as follows:\n *\n\\verbatim\n{\n\t\"request\" : \"rtp_forward\",\n\t\"streams\" : [\n\t\t{\n\t\t\t\"type\": \"<what we want forward: must be one of audio, video, peer_audio, peer_video>\",\n\t\t\t\"host\" : \"<host address to forward the packets to>\",\n\t\t\t\"host_family\" : \"<optional; ipv4 by default>\",\n\t\t\t\"port\" : <port to forward the packets to>,\n\t\t\t\"ssrc\" : <SSRC to use to use when forwarding; optional>,\n\t\t\t\"pt\" : <payload type to use when forwarding; optional>,\n\t\t\t\"srtp_suite\" : <length of authentication tag (32 or 80); optional>,\n\t\t\t\"srtp_crypto\" : \"<key to use as crypto (base64 encoded key as in SDES); optional>\"\n\t\t},\n\t\t{\n\t\t\t.. other streams, if needed..\n\t\t}\n\t]\n}\n\\endverbatim\n *\n * The syntax of the request makes it easy to set up multiple RTP forwarders\n * for a call at the same time, by adding multiple objects as part of the\n * \\c streams array.\n *\n * A successful request will result in an \\c rtp_forward event, containing\n * the relevant info associated to the new forwarder(s):\n *\n\\verbatim\n{\n\t\"nosip\" : \"event\",\n\t\"result\" : {\n\t\t\"event\" : \"rtp_forward\",\n\t\t\"forwarders\" : [\n\t\t\t{\n\t\t\t\t\"stream_id\" : <unique numeric ID assigned to this forwarder, if any>,\n\t\t\t\t\"type\" : \"<type of this forwarder, as configured in the request>\",\n\t\t\t\t\"host\" : \"<host this forwarder is streaming to, same as request if not resolved>\",\n\t\t\t\t\"port\" : <port this forwarder is streaming to, same as request if configured>,\n\t\t\t\t\"media\" : \"<audio or video>\",\n\t\t\t\t\"ssrc\" : <SSRC this forwarder is using, if any>,\n\t\t\t\t\"pt\" : <payload type this forwarder is using, if any>,\n\t\t\t\t\"srtp\" : <true|false, whether the RTP stream is encrypted>\n\t\t\t},\n\t\t\t// Other forwarders, if configured\n\t\t]\n\t}\n}\n\\endverbatim\n *\n * The \\c stream_id property returned for each forwarder is what will\n * need to be used for managing it, i.e., to destroy it once done.\n *\n * To stop a previously created RTP forwarder and stop it, you can use\n * the \\c stop_rtp_forward request, which has to be formatted as follows:\n *\n\\verbatim\n{\n\t\"request\" : \"stop_rtp_forward\",\n\t\"stream_id\" : <unique numeric ID of the RTP forwarder>\n}\n\\endverbatim\n *\n * A successful request will result in a \\c stop_rtp_forward event:\n *\n\\verbatim\n{\n\t\"nosip\" : \"event\",\n\t\"result\" : {\n\t\t\"event\" : \"stop_rtp_forward\",\n\t\t\"stream_id\" : <unique numeric ID, same as request>\n\t}\n}\n\\endverbatim\n *\n * To get a list of all the forwarders for an active call, instead, you\n * can make use of the \\c listforwarders request, which has to be\n * formatted as follows:\n *\n\\verbatim\n{\n\t\"request\" : \"listforwarders\"\n}\n\\endverbatim\n *\n * A successful request will produce a list of RTP forwarders in a\n * \\c forwarders event:\n *\n\\verbatim\n{\n\t\"nosip\" : \"event\",\n\t\"result\" : {\n\t\t\"event\" : \"forwarders\",\n\t\t\"forwarders\" : [\t\t// Array of RTP forwarders\n\t\t\t{\t// RTP forwarder #1\n\t\t\t\t\"stream_id\"

For more information on how Janus implements recordings\n * natively and the MJR format, refer to the \\ref recordings documentation.\n *\n * This application aims at showing how easy recording frames sent by\n * a peer is, and how this recording can be re-used directly, without\n * necessarily involving a post-processing process (e.g., through the\n * tool we provide in janus-pp-rec.c). Notice that only audio and video\n * can be recorded and replayed in this plugin: if you're interested in\n * recording data channel messages (which Janus and the .mjr format do\n * support), you should use a different plugin instead.\n *\n * The configuration process is relatively straightforward: in the simplest\n * configuration, you just choose where the recordings should be saved.\n * The same folder will also be used to list the available recordings that\n * can be replayed.\n *\n * Notice that, by default, all recordings are public, which means any\n * user connecting to the plugin and asking for a list of recordings will\n * be able to obtain their IDs. Recordings can be marked as private to\n * avoid that, meaning that users will only be able to consume such a\n * recording if they're aware of its ID via out of band mechanisms.\n * Marking a recording as private can be done in two different ways:\n *\n * -# via the API, that is when the recording is created;\n * -# by setting the \\c private property to \\c true in the plugin\n * configuration file, which will automatically mark all new recordings\n * as private by default unless otherwise specified in the API request.\n *\n * \\note The application creates a special file in INI format with\n * <tt>.nfo</tt> extension for each recording that is saved. This is necessary\n * to map a specific audio .mjr file to a different video .mjr one, as\n * they always get saved in different files. If you want to replay\n * recordings you took in a different application (e.g., the streaming\n * or videoroom plugins) just copy the related files in the folder you\n * configured this plugin to use and create a .nfo file in the same\n * folder to create a mapping, e.g.:\n *\n * \t\t[12345678]\n * \t\tname = My videoroom recording\n * \t\tdate = 2014-10-14 17:11:26\n * \t\tprivate = false\n * \t\taudio = videoroom-audio.mjr\n * \t\tvideo = videoroom-video.mjr\n *\n * Data channel recordings are supported via a \\c data attribute as well.\n *\n * \\section recplayapi Record&Play API\n *\n * The Record&Play API supports several requests, some of which are\n * synchronous and some asynchronous. There are some situations, though,\n * (invalid JSON, invalid request) which will always result in a\n * synchronous error response even for asynchronous requests.\n *\n * \\c list , \\c update and \\c configure are synchronous requests, which means you'll\n * get a response directly within the context of the transaction. \\c list\n * lists all the available recordings, while \\c update forces the plugin\n * to scan the folder of recordings again in case some were added manually\n * and not indexed in the meanwhile. The \\c configure request can be used\n * to tweak some settings while recording a session.\n *\n * The \\c record , \\c play , \\c start , \\c pause , \\c resume and \\c stop requests instead are\n * all asynchronous, which means you'll get a notification about their\n * success or failure in an event. \\c record asks the plugin to start\n * recording a session; \\c play asks the plugin to prepare the playout\n * of one of the previously recorded sessions; \\c start starts the\n * actual playout, and \\c stop stops whatever the session was for, i.e.,\n * recording or replaying. Recording sessions can also be dynamically\n * paused and resumed using \\c pause and \\c resume : the pauses will be\n * omitted from the recording, meaning recordings will not have holes\n * in them, and will move from one section to the other with no pause.\n *\n * The \\c list request has to be formatted as follows:\n *\n\\verbatim\n{\n\t\"request\" : \"list\",\n\t\"admin_key\" : \"<plugin administrator key; optional>\"\n}\n\\endverbatim\n *\n * A successful request will result in an array of recordings:\n *\n\\verbatim\n{\n\t\"recordplay\" : \"list\",\n\t\"list\": [\t// Array of recording objects\n\t\t{\t\t\t// Recording #1\n\t\t\t\"id\": <numeric ID>,\n\t\t\t\"name\": \"<Name of the recording>\",\n\t\t\t\"date\": \"<Date of the recording>\",\n\t\t\t\"audio\": \"<Audio rec file, if any; optional>\",\n\t\t\t\"video\": \"<Video rec file, if any; optional>\",\n\t\t\t\"data\": \"<Data rec file, if any; optional>\",\n\t\t\t\"audio_codec\": \"<Audio codec, if any; optional>\",\n\t\t\t\"video_codec\": \"<Video codec, if any; optional>\"\n\t\t},\n\t\t<other recordings>\n\t]\n}\n\\endverbatim\n *\n * An error instead (and the same applies to all other requests, so this\n * won't be repeated) would provide both an error code and a more verbose\n * description of the cause of the issue:\n *\n\\verbatim\n{\n\t\"recordplay\" : \"event\",\n\t\"error_code\" : <numeric ID, check Macros below>,\n\t\"error\" : \"<error description as a string>\"\n}\n\\endverbatim\n *\n * Notice that, as explained previously, the \\c list request will only\n * return the list of all recordings who were \\b not marked as private.\n * To return the list of private recordings as well, the right \\c admin_key\n * must be provided as well. In case no \\c admin_key was configured,\n * then the list of private recordings will never be returned.\n *\n * The \\c update request instead has to be formatted as follows:\n *\n\\verbatim\n{\n\t\"request\" : \"update\",\n\t\"admin_key\" : \"<plugin administrator key; mandatory, if configured>\"\n}\n\\endverbatim\n *\n * which will always result in an immediate ack ( \\c ok ):\n *\n\\verbatim\n{\n\t\"recordplay\" : \"ok\",\n}\n\\endverbatim\n *\n * Notice that, if an \\c admin_key was configured in the configuration\n * file, it is a mandatory property to pass in an \\c update request as\n * well.\n *\n * Coming to the asynchronous requests, \\c record has to be attached to\n * a JSEP offer (failure to do so will result in an error) and has to be\n * formatted as follows:\n *\n\\verbatim\n{\n\t\"request\" : \"record\",\n\t\"id\" : <unique numeric ID for the recording; optional, will be chosen by the server if missing>\n\t\"name\" : \"<Pretty name for the recording>\",\n\t\"is_private\" : <true|false, whether the recording should be listable; the default is what was configured in the plugin config file>,\n\t\"filename\" : \"<Base path/name for the file (media type and extension added by the plugin); optional>\",\n\t\"audiocodec\" : \"<name of the audio codec we prefer for the recording; optional>\",\n\t\"videocodec\" : \"<name of the video codec we prefer for the recording; optional>\",\n\t\"videoprofile\" : \"<in case the video codec supports, profile to use (e.g., \"2\" for VP9, or \"42e01f\" for H.264); optional>\",\n\t\"opusred\" : <true|false, whether RED should be negotiated for audio, if offered; optional (default=false)>,\n\t\"textdata\" : \"<in case data channels have to be recorded, whether the data will be text (default) or binary; optional>\"\n}\n\\endverbatim\n *\n * A successful management of this request will result in a \\c recording\n * event which will include the unique ID of the recording and a JSEP\n * answer to complete the setup of the associated PeerConnection to record:\n *\n\\verbatim\n{\n\t\"recordplay\" : \"event\",\n\t\"result\": {\n\t\t\"status\" : \"recording\",\n\t\t\"id\" : <unique numeric ID>,\n\t\t\"is_private\" : <true|false, same as the request>\n\t}\n}\n\\endverbatim\n *\n * Some properties of the recording session can be tweaked dynamically\n * via the \\c configure request, and has to be formatted as follows:\n *\n\\verbatim\n{\n\t\"request\" : \"configure\",\n\t\"video-bitrate-max\", <bitrate cap that should be forced (via REMB) on the recorder>,\n\t\"video-keyframe-interval\", <how often, in seconds, the plugin should send a PLI to the recorder to request a keyframe>\n}\n\\endverbatim\n *\n * A successful request will result in a confirmation of :\n *\n\\verbatim\n{\n\t\"recordplay\" : \"configure\",\n\t\"status\" : \"ok\",\n\t\"settings\" : {\n\t\t\"video-bitrate-max\" : <current value of the property>,\n\t\t\"video-keyframe-interval\" : <current value of the property>\n\t}\n}\n\\endverbatim\n *\n * You can pause the recording process (meaning that RTP packets will keep\n * on flowing but will not be recorded to file) using the \\c pause request:\n *\n\\verbatim\n{\n\t\"request\" : \"pause\",\n}\n\\endverbatim\n *\n * This will result in a \\c paused status:\n *\n\\verbatim\n{\n\t\"recordplay\" : \"event\",\n\t\"result\": {\n\t\t\"status\" : \"paused\",\n\t\t\"id\" : <unique numeric ID of the paused recording>\n\t}\n}\n\\endverbatim\n *\n * To resume the recording process you can use the \\c resume request:\n *\n\\verbatim\n{\n\t\"request\" : \"resume\",\n}\n\\endverbatim\n *\n * This will result in a \\c resumed status:\n *\n\\verbatim\n{\n\t\"recordplay\" : \"event\",\n\t\"result\": {\n\t\t\"status\" : \"resumed\",\n\t\t\"id\" : <unique numeric ID of the paused recording>\n\t}\n}\n\\endverbatim\n *\n * A \\c stop request can interrupt the recording process and tear the\n * associated PeerConnection down:\n *\n\\verbatim\n{\n\t\"request\" : \"stop\",\n}\n\\endverbatim\n *\n * This will result in a \\c stopped status:\n *\n\\verbatim\n{\n\t\"recordplay\" : \"event\",\n\t\"result\": {\n\t\t\"status\" : \"stopped\",\n\t\t\"id\" : <unique numeric ID of the interrupted recording>,\n\t\t\"is_private\" : <whether the interrupted recording is private>\n\t}\n}\n\\endverbatim\n *\n * For what concerns the playout, instead, the process is slightly\n * different: you first choose a recording to replay, using \\c play ,\n * and then start its playout using a \\c start request. Just as before,\n * a \\c stop request will interrupt the playout and tear the PeerConnection\n * down. It's very important to point out that no JSEP offer must be\n * sent for replaying a recording: in this case, it will always be the\n * plugin to generate a JSON offer (in response to a \\c play request),\n * which means you'll then have to provide a JSEP answer within the\n * context of the following \\c start request which will close the circle.\n * Notice that \\c play can be used to replay private recordings as well:\n * a recording marked as private is simply not returned when retrieving\n * the list of available recordings, but if the user is aware of a\n * recording ID through other means, then that recording can be replayed\n * as all other non-private recordings.\n *\n * A \\c play request has to be formatted as follows:\n *\n\\verbatim\n{\n\t\"request\" : \"play\",\n\t\"id\" : <unique numeric ID of the recording to replay>\n}\n\\endverbatim\n *\n * This will result in a \\c preparing status notification which will be\n * attached to the JSEP offer originated by the plugin in order to\n * match the media available in the recording:\n *\n\\verbatim\n{\n\t\"recordplay\" : \"event\",\n\t\"result\": {\n\t\t\"status\" : \"preparing\",\n\t\t\"id\" : <unique numeric ID of the recording>\n\t}\n}\n\\endverbatim\n *\n * A \\c start request, which as anticipated must be attached to the JSEP\n * answer to the previous offer sent by the plugin, has to be formatted\n * as follows:\n *\n\\verbatim\n{\n\t\"request\" : \"start\",\n}\n\\endverbatim\n *\n * This will result in a \\c playing status notification:\n *\n\\verbatim\n{\n\t\"recordplay\" : \"event\",\n\t\"result\": {\n\t\t\"status\" : \"playing\"\n\t}\n}\n\\endverbatim\n *\n * Just as before, a \\c stop request can interrupt the playout process at\n * any time, and tear the associated PeerConnection down:\n *\n\\verbatim\n{\n\t\"request\" : \"stop\",\n}\n\\endverbatim\n *\n * This will result in a \\c stopped status:\n *\n\\verbatim\n{\n\t\"recordplay\" : \"event\",\n\t\"result\": {\n\t\t\"status\" : \"stopped\"\n\t}\n}\n\\endverbatim\n *\n * If the plugin detects a loss of the associated PeerConnection, whether\n * as a result of a \\c stop request or because the connection

Specifically, when attaching to the plugin peers\n * are requested to provide their SIP server credentials, i.e., the address\n * of the SIP server and their username/secret. This results in the plugin\n * registering at the SIP server and acting as a SIP client on behalf of\n * the web peer. Most of the SIP states and lifetime are masked by the plugin,\n * and only the relevant events (e.g., INVITEs and BYEs) and functionality\n * (call, hangup) are made available to the web peer: peers can call\n * extensions at the SIP server or wait for incoming INVITEs, and during\n * a call they can send DTMF tones. Calls can do plain RTP or SDES-SRTP.\n *\n * The concept behind this plugin is to allow different web pages associated\n * to the same peer, and hence the same SIP user, to attach to the plugin\n * at the same time and yet just do a SIP REGISTER once. The same should\n * apply for calls: while an incoming call would be notified to all the\n * web UIs associated to the peer, only one would be able to pick up and\n * answer, in pretty much the same way as SIP forking works but without the\n * need to fork in the same place. This specific functionality, though, has\n * not been implemented as of yet.\n *\n * \\section sipapi SIP Plugin API\n *\n * All requests you can send in the SIP Plugin API are asynchronous,\n * which means all responses (successes and errors) will be delivered\n * as events with the same transaction.\n *\n * The supported requests are \\c register , \\c unregister , \\c call ,\n * \\c progress , \\c accept , \\c decline , \\c info , \\c message , \\c dtmf_info ,\n * \\c subscribe , \\c unsubscribe , \\c transfer , \\c recording , \\c keyframe ,\n * \\c hold , \\c unhold , \\c update , \\c rtp_forward , \\c stop_rtp_forward ,\n * \\c listforwarders and \\c hangup . \\c register can be used,\n * as the name suggests, to register a username at a SIP registrar to\n * call and be called, while \\c unregister unregisters it; \\c call is used\n * to send an INVITE to a different SIP URI through the plugin; in case one\n * is invited instead of inviting, \\c progress, \\c accept and \\c decline\n * requests may be used. \\c progress request is optional, and it is used to\n * send 183 Session Progress response back to the caller, while\n * \\c accept and \\c decline are used to accept or reject the call respectively;\n * \\c transfer takes care of attended and blind transfers (see \\ref siptr for\n * more details); \\c hold and \\c unhold can be used respectively to put a\n * call on-hold and to resume it; \\c info allows you to send a generic\n * SIP INFO request, while \\c dtmf_info is focused on using INFO for DTMF\n * instead; \\c message is the method you use to send a SIP message\n * to the other peer; \\c subscribe and \\c unsubscribe are used to deal\n * with SIP events, i.e., to send SUBSCRIBE requests that will result in\n * NOTIFY asynchronous events; \\c recording is used, instead, to record the\n * conversation to one or more .mjr files (depending on the direction you\n * want to record); \\c update allows you to update an existing session\n * (e.g., to do a renegotiation or force an ICE restart); \\c rtp_forward ,\n * \\c stop_rtp_forward and \\c listforwarders are related to the\n * \\ref siprtpfwd functionality; finally, \\c hangup\n * can be used to terminate the communication at any time, either to\n * hangup (BYE) an ongoing call or to cancel/decline (CANCEL/BYE) a call\n * that hasn't started yet.\n *\n * No matter the request, an error response or event is always formatted\n * like this:\n *\n\\verbatim\n{\n\t\"sip\" : \"event\",\n\t\"error_code\" : <numeric ID, check Macros below>,\n\t\"error\" : \"<error description as a string>\"\n}\n\\endverbatim\n *\n * Notice that the error syntax above refers to the plugin API messaging,\n * and not SIP error codes obtained in response to SIP requests, which\n * are notified using a different syntax:\n *\n\\verbatim\n{\n\t\"sip\" : \"event\",\n\t\"result\" : {\n\t\t\"event\" : \"<name of the error event>\",\n\t\t\"code\" : <SIP error code>,\n\t\t\"reason\" : \"<SIP error reason>\",\n\t\t\"reason_header\" : \"<Reason header text; optional>\",\n\t\t\"reason_header_protocol\" : \"<Reason header protocol; optional>\",\n\t\t\"reason_header_cause\" : \"<Reason header cause code; optional>\",\n\t\t\"headers\" : \"<object with key/value strings; custom headers extracted from SIP event based on incoming_header_prefix defined in register request; optional>\"\n\t}\n}\n\\endverbatim\n *\n * Coming to the available requests, you send a SIP REGISTER using the\n * \\c register request. To be more precise, a \\c register request MAY result\n * in a SIP REGISTER, as this method actually provides ways to start using\n * a SIP account with no need for a registration. It is the case, for instance,\n * of the so-called \\c guest registrations: if you register as a \\c guest ,\n * it means you'll use the provided SIP URI in your \\c From headers for calls,\n * but you will actually not send a SIP REGISTER; this is especially useful\n * for outgoing calls to services that don't require registration (e.g., IVR\n * systems, or conference bridges), but also means you won't be able to\n * receive calls unless peers know what your private SIP address is. A SIP\n * REGISTER isn't sent also when registering as a \\c helper : as we'll\n * explain later, \\c helper sessions are sessions only meant to facilitate\n * the setup of \\ref sipmc.\n *\n * That said, a \\c register request has to be formatted as follows:\n *\n\\verbatim\n{\n\t\"request\" : \"register\",\n\t\"type\" : \"<if guest or helper, no SIP REGISTER is actually sent; optional>\",\n\t\"send_register\" : <true|false; if false, no SIP REGISTER is actually sent; optional>,\n\t\"force_udp\" : <true|false; if true, forces UDP for the SIP messaging; optional>,\n\t\"force_tcp\" : <true|false; if true, forces TCP for the SIP messaging; optional>,\n\t\"sips\" : <true|false; if true, configures a SIPS URI too when registering; optional>,\n\t\"rfc2543_cancel\" : <true|false; if true, configures sip client to CANCEL pending INVITEs without having received a provisional response first; optional>,\n\t\"automatic_ringing\" : <true|false; if false, don't generate ringing automatically as soon as an INVITE; optional>,\n\t\"username\" : \"<SIP URI to register; mandatory>\",\n\t\"secret\" : \"<password to use to register; optional>\",\n\t\"ha1_secret\" : \"<prehashed password to use to register; optional>\",\n\t\"authuser\" : \"<username to use to authenticate (overrides the one in the SIP URI); optional>\",\n\t\"display_name\" : \"<display name to use when sending SIP REGISTER; optional>\",\n\t\"user_agent\" : \"<user agent to use when sending SIP REGISTER; optional>\",\n\t\"proxy\" : \"<server to register at; optional, as won't be needed in case the REGISTER is not goint to be sent (e.g., guests)>\",\n\t\"outbound_proxy\" : \"<outbound proxy to use, if any; optional>\",\n\t\"headers\" : \"<object with key/value mappings (header name/value), to specify custom headers to add to the SIP REGISTER; optional>\",\n\t\"contact_params\" : \"<array of key/value objects, to specify custom Contact URI params to add to the SIP REGISTER; optional>\",\n\t\"incoming_header_prefixes\" : \"<array of strings, to specify custom (non-standard) headers to read on incoming SIP events; optional>\",\n\t\"refresh\" : \"<true|false; if true, only uses the SIP REGISTER as an update and not a new registration; optional>\",\n\t\"master_id\" : \"<ID of an already registered account, if this is an helper for multiple calls (more on that later); optional>\",\n \t\"register_ttl\" : \"<integer; number of seconds after which the registration should expire; optional>\"\n}\n\\endverbatim\n *\n * A \\c registering event will be sent back, as this is an asynchronous request.\n *\n * In case it is required to, this request will originate a SIP REGISTER to the\n * specified server with the right credentials. 401 and 407 responses will be\n * handled automatically, and so errors will not be notified back to the caller\n * unless they're definitive (e.g., wrong credentials). A failure to register\n * will return an error with name \\c registration_failed.

To do that, you need to use the \\c subscribe\n * request, which has to be formatted like this:\n *\n\\verbatim\n{\n\t\"request\" : \"subscribe\",\n\t\"call_id\" : \"<user-defined value of Call-ID SIP header used in all SIP requests throughout the subscription; optional>\",\n\t\"event\" : \"<the event to subscribe to, e.g., 'message-summary'; mandatory>\",\n\t\"accept\" : \"<what should be put in the Accept header; optional>\",\n\t\"to\" : \"<who should be the SUBSCRIBE addressed to; optional, will use the user's identity if missing>\",\n\t\"subscribe_ttl\" : \"<integer; number of seconds after which the subscription should expire; optional>\",\n\t\"content\" : \"<content to put in the body of the SUBSCRIBE; optional>\",\n\t\"content_type\" : \"<content-type of the body; optional>\",\n\t\"headers\" : \"<array of key/value objects, to specify custom headers to add to the SIP SUBSCRIBE; optional>\"\n}\n\\endverbatim\n *\n * A \\c subscribing event will be sent back, followed by a \\c subscribe_succeeded if\n * the SUBSCRIBE request was accepted, and a \\c subscribe_failed if the transaction\n * failed instead. Incoming SIP NOTIFY events, instead, are notified in \\c notify events:\n *\n\\verbatim\n{\n\t\"sip\" : \"event\",\n\t\"call_id\" : \"<value of SIP Call-ID header for related subscription>\",\n\t\"result\" : {\n\t\t\"event\" : \"notify\",\n\t\t\"notify\" : \"<name of the event that the user is subscribed to, e.g., 'message-summary'>\",\n\t\t\"substate\" : \"<substate of the subscription, e.g., 'active'>\",\n\t\t\"content-type\" : \"<content-type of the message>\"\n\t\t\"content\" : \"<content of the message>\",\n\t\t\"headers\" : \"<object with key/value strings; custom headers extracted from SIP event based on incoming_header_prefix defined in register request; optional>\"\n\t}\n}\n\\endverbatim\n *\n * You can also record a SIP call, and it works pretty much the same the\n * VideoCall plugin does. Specifically, you make use of the \\c recording\n * request to either start or stop a recording, using the following syntax:\n *\n\\verbatim\n{\n\t\"request\" : \"recording\",\n\t\"action\" : \"<start|stop, depending on whether you want to start or stop recording something>\"\n\t\"audio\" : <true|false; whether or not our audio should be recorded>,\n\t\"video\" : <true|false; whether or not our video should be recorded>,\n\t\"peer_audio\" : <true|false; whether or not our peer's audio should be recorded>,\n\t\"peer_video\" : <true|false; whether or not our peer's video should be recorded>,\n\t\"send_peer_pli\" : <true|false; whether or not send PLI to request keyframe from peer>,\n\t\"filename\" : \"<base path/filename to use for all the recordings>\"\n}\n\\endverbatim\n *\n * As you can see, this means that the two sides of conversation are recorded\n * separately, and so are the audio and video streams if available. You can\n * choose which ones to record, in case you're interested in just a subset.\n * The \\c filename part is just a prefix, and dictates the actual filenames\n * that will be used for the up-to-four recordings that may need to be enabled.\n *\n * A \\c recordingupdated event is sent back in case the request is successful.\n *\n * To programmatically send a video keyframe request to either the WebRTC user\n * or the SIP peer (or both), the \\c keyframe request can be used. This\n * request is particularly useful when the SIP peer doesn't support RTCP PLI,\n * and so may use other mechanisms (e.g., via signalling) to ask for a keyframe\n * to get video working. By using this request, the WebRTC user can ask Janus\n * to originate a PLI programmatically. The direction of the keyframe request\n * can be provided by using the \\c user and \\c peer properties: if \\c user\n * is \\c TRUE a keyframe request will be sent by Janus to the WebRTC user;\n * if \\c peer is \\c TRUE a keyframe request will be sent by Janus to the\n * SIP peer. In both cases an RTCP PLI message will be sent. The syntax of\n * the message is the following:\n *\n\\verbatim\n{\n\t\"request\" : \"keyframe\",\n\t\"user\" : <true|false; whether or not to send a keyframe request to the WebRTC user>,\n\t\"peer\" : <true|false; whether or not to send a keyframe request to the SIP peer>\n}\n\\endverbatim\n *\n * A \\c keyframesent event is sent back in case the request is successful.\n *\n * \\section sipmc Simultaneous SIP calls using the same account\n *\n * As anticipated in the previous sections, attaching to the SIP plugin\n * with a Janus handle means creating a SIP stack on behalf of a user\n * or application: this typically means registering an account, and being\n * able to start or receive calls, handle subscriptions, and so on. This\n * also means that, since in Janus each core handle can only be associated\n * with a single PeerConnection, each SIP account is limited to a single\n * call per time: if a user is in a SIP session already, and another call\n * comes in, it's automatically rejected with a \\c 486 \\c Busy .\n *\n * While usually not a big deal, there are use cases where it might make\n * sense to be able to support multiple concurrent calls, and maybe switch\n * from one to the other seamlessly. This is possible in the SIP plugin\n * using the so-called \\c helper sessions. Specifically, \\c helper sessions\n * work under the assumption that there's a \\c master session that is\n * registered normally (the \"regular\" SIP plugin handle, that is), and\n * that these \\c helper sessions can simply be associated to that: any time\n * another concurrent call is needed, if the \\c master session is busy\n * one of the \\c helpers can be used; the more \\c helper sessions are\n * available, the more simultaneous calls can be established.\n *\n * The way this works is simple:\n *\n * 1. you create a SIP session the usual way, and send a regular \\c register\n * there; this will be the \\c master session, and will return a \\c master_id\n * when successfully registered;\n * 2. for each \\c helper you want to add, you attach a new Janus handle\n * to the SIP plugin, and send a \\c register with \\c type: \\c \"helper\" and\n * providing the same \\c username as the master, plus a \\c master_id attribute\n * referencing the main session;\n * 3. at this point, the new \\c helper is associated to the \\c master ,\n * meaning it can be used to start new calls or receive calls exactly\n * as the main session, and using the same account information, credentials,\n * etc.\n *\n * Notice that, as soon as the \\c master unregisters, or the Janus handle\n * it's on is detached, all the \\c helper sessions associated to it are\n * automatically torn down as well. Specifically, the plugin will forcibly\n * detach the related handles. Should you need to register again, and want\n * some helpers there too, you'll have to add them again.\n *\n * If you want to see this in practice, the SIP plugin demo has a \"hidden\"\n * function you can invoke from the JavaScript console to play with helpers:\n * calling the \\c addHelper() function will add a new helper, and show additional\n * controls. You can add as many helpers as you want.\n *\n * \\section siptr Attended and blind transfers\n *\n * The Janus SIP plugin supports both attended and blind transfers, and to\n * do so mostly relies on the multiple calls functionality: as such, make\n * sure you've read and are familiar with the section on \\ref sipmc .\n *\n * Most of the transfer-related functionality are based on existing messages\n * and events already documented in the previous section, but there are a\n * few aspects you need to be aware of. First of all, if you're the transferor,\n * you need to use a new request called \\c transfer , that allows you to\n * send a SIP REFER to the transferee so to reach a different target. The\n * \\c transfer request must be formatted like this:\n *\n\\verbatim\n{\n\t\"request\" : \"transfer\",\n\t\"uri\" : \"<SIP URI to send the transferee too>\",\n\t\"replace\" : \"<call-ID of the call this attended transfer is supposed to replace; default is none, which means blind/unattended transfer>\"\n}\n\\endverbatim\n *\n * Whether this is a blind (no call to replace) or attended transfer,\n * a \\c transferring event will be sent back, as this is an asynchronous\n * request. Further updates will come in the form of NOTIFY-related events,\n * as a REFER implicitly creates a subscription.\n *\n * The recipient of a REFER, instead, will receive an asynchronous event\n * called \\c transfer as well, with info it needs to be aware of. In fact,\n * the SIP plugin doesn't do anything automatically: an incoming REFER is\n * notified to the application, so that it can decide whether to follow\n * up on the transfer or not. The syntax of the event is the following:\n *\n\\verbatim\n{\n\t\"sip\" : \"event\",\n\t\"result\" : {\n\t\t\"event\" : \"transfer\",\n\t\t\"refer_id\" : <unique ID, internal to Janus, of this referral>,\n\t\t\"refer_to\" : \"<SIP URI to call>\",\n\t\t\"referred_by\" : \"<SIP URI header conveying the identity of the transferor; optional>\",\n\t\t\"replaces\" : \"<call-ID of the call this transfer is supposed to replace; optional, and only present for attended transfers>\",\n\t\t\"headers\" : \"<object with key/value strings; custom headers extracted from SIP event based on incoming_header_prefix defined in register request; optional>\"\n\t}\n}\n\\endverbatim\n *\n * The most important property in that list is \\c refer_id as that value\n * must be included in the \\c call request to call the target, if the\n * transfer is accepted: in fact, that's the only way the SIP plugin has\n * to correlate the new outgoing call to the previous transfer request,\n * and thus be able to notify the transferor about how the call is\n * proceeding by means of NOTIFY events. Notice that, if the transferee\n * decides to follow up on the transfer request, and they're already in\n * a call (e.g., with the transferor), then they must use a different\n * handle for the purpose, e.g., via a helper as described in the\n * \\ref sipmc section.\n *\n * The transfer target will receive the call exactly as previously discussed,\n * with the difference that it may or may not include a \\c referred_by\n * property for information purposes. Just as the transferee, if they're\n * already in a call, it's up to the application to create a helper to\n * setup a new Janus handle to accept the transfer.\n *\n * Notice that the plugin will NOT put the involved calls on-hold, or\n * automatically close calls that are meant to be replaced by a transfer.\n * All this is the application responsibility, and as such it's up to\n * the developer to react to events accordingly.\n *\n * \\subsection siprtpfwd RTP forwarders in the SIP plugin\n *\n * RTP forwarders are a quite useful functionality that a few plugins\n * in Janus can take advantage of. As the name suggests, their main\n * purpose is indeed forwarding/relaying RTP traffic to an external\n * backend, for further processing or management of media packets outside\n * of the context of the plugin that's responsible for it.\n *\n * Within the context of the SIP plugin, RTP forwarders allow you to\n * send the RTP traffic belonging to a specific SIP call to an external\n * backend, e.g., to a component implementing transcriptions, a remote\n * recorder, a lawful interception application or whatever else may have\n * a need for the content of a call in real-time. The RTP forwarder\n * functionality is conceived in a way that allows you to separately\n * forward individual RTP streams: this allows you to only forward, e.g.,\n * the audio packets of the local Janus user, only forward the video\n * packets of the SIP peer, forward everything, or any combination in\n * between. For every media stream you're interested in forwarding, a\n * separate RTP forwarder will be needed, which is what enables this\n * flexibility. Multiple forwarders can be created for the same stream,\n * in case the same RTP traffic should be sent to multiple backends at\n * the same time.\n *\n * Notice that SIP is not involved for RTP forwarders. RTP traffic is\n * relayed out of context, using a specific API that is part of the\n * SIP plugin itself. RTP forwarders will need an ongoing SIP call to\n * operate, though, as they'll be associated to existing media streams\n * in an existing SIP call; more specifically, forwarding requests must\n * be performed on the handle that's handling the call that should be\n * the target of its operations, which is why the related requests don't\n * need any identifier (the scope is automatically obtained from the\n * context of the handle). Forwarders that were created while a call\n * was active will automatically be destroyed when the call is hung up\n *\n * To setup new RTP forwarders, you can use the \\c rtp_forward request,\n * which must be formatted as follows:\n *\n\\verbatim\n{\n\t\"request\" : \"rtp_forward\",\n\t\"streams\" : [\n\t\t{\n\t\t\t\"type\": \"<what we want forward: must be one of audio, video, peer_audio, peer_video>\",\n\t\t\t\"host\" : \"<host address to forward the packets to>\",\n\t\t\t\"host_family\" : \"<optional; ipv4 by default>\",\n\t\t\t\"port\" : <port to forward the packets to>,\n\t\t\t\"ssrc\" : <SSRC to use to use when forwarding; optional>,\n\t\t\t\"pt\" : <payload type to use when forwarding; optional>,\n\t\t\t\"srtp_suite\" : <length of authentication tag (32 or 80); optional>,\n\t\t\t\"srtp_crypto\" : \"<key to use as crypto (base64 encoded key as in SDES); optional>\"\n\t\t},\n\t\t{\n\t\t\t.. other streams, if needed..\n\t\t}\n\t]\n}\n\\endverbatim\n *\n * The syntax of the request makes it easy to set up multiple RTP forwarders\n * for a call at the same time, by adding multiple objects as part of the\n * \\c streams array.\n *\n * A successful request will result in an \\c rtp_forward event, containing\n * the relevant info associated to the new forwarder(s):\n *\n\\verbatim\n{\n\t\"sip\" : \"event\",\n\t\"result\" : {\n\t\t\"event\" : \"rtp_forward\",\n\t\t\"forwarders\" : [\n\t\t\t{\n\t\t\t\t\"stream_id\" : <unique numeric ID assigned to this forwarder, if any>,\n\t\t\t\t\"type\" : \"<type of this forwarder, as configured in the request>\",\n\t\t\t\t\"host\" : \"<host this forwarder is streaming to, same as request if not resolved>\",\n\t\t\t\t\"port\" : <port this forwarder is streaming to, same as request if configured>,\n\t\t\t\t\"media\" : \"<audio or video>\",\n\t\t\t\t\"ssrc\" : <SSRC this forwarder is using, if any>,\n\t\t\t\t\"pt\" : <payload type this forwarder is using, if any>,\n\t\t\t\t\"srtp\" : <true|false, whether the RTP stream is encrypted>\n\t\t\t},\n\t\t\t// Other forwarders, if configured\n\t\t]\n\t},\n\t\"call_id\": \"<call-ID of the call>\"\n}\n\\endverbatim\n *\n * The \\c stream_id property returned for each forwarder is what will\n * need to be used for managing it, i.e., to destroy it once done.\n *\n * To stop a previously created RTP forwarder and stop it, you can use\n * the \\c stop_rtp_forward request, which has to be formatted as follows:\n *\n\\verbatim\n{\n\t\"request\" : \"stop_rtp_forward\",\n\t\"stream_id\" : <unique numeric ID of the RTP forwarder>\n}\n\\endverbatim\n *\n * A successful request will result in a \\c stop_rtp_forward event:\n *\n\\verbatim\n{\n\t\"sip\" : \"event\",\n\t\"result\" : {\n\t\t\"event\" : \"stop_rtp_forward\",\n\t\t\"stream_id\" : <unique numeric ID, same as request>\n\t},\n\t\"call_id\" : \"<call-ID of the call>\"\n}\n\\endverbatim\n *\n * To get a list of all the forwarders for an active call, instead, you\n * can make use of the \\c listforwarders request, which has to be\n * formatted as follows:\n *\n\\verbatim\n{\n\t\"request\" : \"listforwarders\"\n}\n\\endverbatim\n *\n * A successful request will produce a list of RTP forwarders in a\n * \\c forwarders event:\n *\n\\verbatim\n{\n\t\"sip\" : \"event\",\n\t\"result\" : {\n\t\t\"event\" : \"forwarders\",\n\t\t\"rtp_forwarders\" : [\t\t// Array of RTP forwarders\n\t\t\t{\t// RTP forwarder #1\n\t\t\t\t\"stream_id\" : <unique numeric ID assigned to this forwarder, if

Any tool that can generate audio/video\n * RTP streams and specify a destination is good for the purpose: the\n * examples section contains samples that make use of GStreamer (http://gstreamer.freedesktop.org/)\n * but other tools like FFmpeg (http://www.ffmpeg.org/), LibAV (http://libav.org/)\n * or others are fine as well. This makes it really easy to capture and\n * encode whatever you want using your favourite tool, and then have it\n * transparently broadcasted via WebRTC using Janus. Notice that we recently\n * added  the possibility to also add a datachannel track to an RTP streaming\n * mountpoint: this allows you to send, via UDP, a text-based message to\n * relay via datachannels (e.g., the title of the current song, if this\n * is a radio streaming channel). When using this feature, though, beware\n * that you'll have to stay within the boundaries of the MTU, as each\n * message will have to stay within the size of an UDP packet.\n *\n * Streams to make available are listed in the plugin configuration file.\n * A pre-filled configuration file is provided in \\c conf/janus.plugin.streaming.jcfg\n * and includes some examples you can start from.\n *\n * To add more streams or modify the existing ones, you can use the following\n * syntax:\n *\n * \\verbatim\nstream-name: {\n\t[settings]\n}\n\\endverbatim\n *\n * with the allowed settings listed below. Notice that, for the sake of\n * simplicity, only the global and legacy properties are listed in the\n * following text: you can use the new stream-based syntax as well (see\n * the 'multistream-test' example below for reference), but in that case\n * all properties whose names start with audio/video/data should be\n * renamed to have that prefix removed. Please refer to the plugin API\n * documentation for more details, as the static configuration in that\n * case mirrors the dynamic API syntax.\n *\n * \\verbatim\ntype = rtp|live|ondemand|rtsp\n       rtp = stream originated by an external tool (e.g., gstreamer or\n             ffmpeg) and sent to the plugin via RTP\n       live = local file streamed live to multiple viewers\n              (multiple viewers = same streaming context)\n       ondemand = local file streamed on-demand to a single listener\n                  (multiple viewers = different streaming contexts)\n       rtsp = stream originated by an external RTSP feed (only\n              available if libcurl support was compiled)\nid = <unique numeric ID>\ndescription = This is my awesome stream\nmetadata = An optional string that can contain any metadata (e.g., JSON)\n\t\t\tassociated with the stream you want users to receive\nis_private = true|false (private streams don't appear when you do a 'list' request)\nfilename = path to the local file to stream (only for live/ondemand)\nsecret = <optional password needed for manipulating (e.g., destroying\n\t\tor enabling/disabling) the stream>\npin = <optional password needed for watching the stream>\naudio = true|false (do/don't stream audio)\nvideo = true|false (do/don't stream video)\n   The following options are only valid for the 'rtp' type:\ndata = true|false (do/don't stream text via datachannels)\naudioport = local port for receiving audio frames\naudiortcpport = local port for receiving and sending audio RTCP feedback\naudiomcast = multicast group for receiving audio frames, if any\naudioiface = network interface or IP address to bind to, if any (binds to all otherwise)\naudiopt = <audio RTP payload type> (e.g., 111)\naudiocodec = name of the audio codec (opus)\naudiofmtp = Codec specific parameters, if any\naudioskew = true|false (whether the plugin should perform skew\n\tanalysis and compensation on incoming audio RTP stream, EXPERIMENTAL)\nvideoport = local port for receiving video frames (only for rtp)\nvideortcpport = local port for receiving and sending video RTCP feedback\nvideomcast = multicast group for receiving video frames, if any\nvideoiface = network interface or IP address to bind to, if any (binds to all otherwise)\nvideopt = <video RTP payload type> (e.g., 100)\nvideocodec = name of the video codec (vp8)\nvideofmtp = Codec specific parameters, if any\nvideosimulcast = true|false (do|don't enable video simulcasting)\nvideoport2 = second local port for receiving video frames (only for rtp, and simulcasting)\nvideoport3 = third local port for receiving video frames (only for rtp, and simulcasting)\nvideoskew = true|false (whether the plugin should perform skew\n\tanalysis and compensation on incoming video RTP stream, EXPERIMENTAL)\nvideosvc = true|false (whether the video will have SVC support; works only for VP9-SVC, default=false)\nh264sps = if using H.264 as a video codec, value of the sprop-parameter-sets\n\tthat would normally be sent via SDP, but that we'll use to instead\n\tmanually ingest SPS and PPS packets via RTP for streams that miss it\ncollision = in case of collision (more than one SSRC hitting the same port), the plugin\n\twill discard incoming RTP packets with a new SSRC unless this many milliseconds\n\tpassed, which would then change the current SSRC (0=disabled)\ndataport = local port for receiving data messages to relay\ndatamcast = multicast group for receiving data messages, if any\ndataiface = network interface or IP address to bind to, if any (binds to all otherwise)\ndatatype = text|binary (type of data this mountpoint will relay, default=text)\ndatabuffermsg = true|false (whether the plugin should store the latest\n\tmessage and send it immediately for new viewers)\nthreads = number of threads to assist with the relaying part, which can help\n\tif you expect a lot of viewers that may cause the RTP receiving part\n\tin the Streaming plugin to slow down and fail to catch up (default=0)\n\nNote: by default, the Streaming plugin only forwards the latest packets\nit receives, never performing any buffering. This means that, for video\nstreams, new viewers may initially start receiving frames they cannot\ndecode right away, since they'd refer to keyframes that were sent before\nthey joined. In such scenarios, they'd have to wait until the next keyframe\narrives before video can be decoded and displayed, which could take a\nwhile depending on the frequency of keyframes encoded by the source.\nFor forwarded streams (e.g., from the VideoRoom) this can be easily\naddressed by using the RTCP support. For sources that can't or won't\nhonour dynamic keyframe requests, a partial and experimental solution\nmight be storing the latest keyframe and the following deltas, to send\nto new viewers before new live packet are delivered. This feature can\nbe enabled in the Streaming plugin using the 'bufferkf_ms' and/or\nthe 'bufferkf_bytes' properties, which configure how many milliseconds\nor how many bytes (in total) should be stored any time a keyframe is\nreceived: data exceeding those limits won't be stored, until a new\nkeyframe arrives. The two properties are not mutually exclusive, and\ncan be configured at the same time: in that case, the first one that\nhits the limit stops the buffering of the current keyframe. Notice\nthat, again, this feature should be considered highly experimental,\nand that it comes with a few considerable drawbacks: the most obvious\none is that, depending on how many packets were stored, new viewers\nmay be hit with a considerable burst of data as soon as they connect,\nwhich may negatively impact performance or even cause issues of its own.\nAlso notice that this is a global, and not per-stream, feature: this\nmeans that if you create a mountpoint with two video streams, the\nfeature will impact both of them, and both streams will have a buffer\nof their own. This also works for RTSP mountpoints.\n\tbufferkf_ms = how many milliseconds of packets to store, starting\n\t\tfrom a new keyframe (default=0)\n\tbufferkf_bytes = how many bytes of packets to store, starting\n\t\tfrom a new keyframe (default=0)\n\nIn case you want to use SRTP for your RTP-based mountpoint, you'll need\nto configure the SRTP-related properties as well, namely the suite to\nuse for hashing (32 or 80) and the crypto information for decrypting\nthe stream (as a base64 encoded string the way SDES does it). Notice\nthat with SRTP involved you'll have to pay extra attention to what you\nfeed the mountpoint, as you may risk getting SRTP decrypt errors:\nsrtpsuite = 32\nsrtpcrypto = WbTBosdVUZqEb6Htqhn+m3z7wUh4RJVR8nE15GbN\n\nThe Streaming plugin can also be used to (re)stream media that has been\nencrypted using something that can be consumed via Insertable Streams.\nIn that case, we only need to be aware of it, so that we can send the\ninfo along with the SDP. How to decrypt the media is out of scope, and\nup to the application since, again, this is end-to-end encryption and\nso neither Janus nor the Streaming plugin have access to anything.\nDO NOT SET THIS PROPERTY IF YOU DON'T KNOW WHAT YOU'RE DOING!\ne2ee = true\n\nTo allow mountpoints to negotiate the playout-delay RTP extension,\nyou can set the 'playoutdelay_ext' property to true: this way, any\nsubscriber can customize the playout delay of incoming video streams,\nassuming the browser supports the RTP extension in the first place.\nplayoutdelay_ext = true\n\nTo allow mountpoints to negotiate the abs-capture-time RTP extension,\nyou can set the 'abscapturetime_src_ext_id' property to value in range 1..14 inclusive: this way, any\nsubscriber can receive the abs-capture-time of incoming RTP streams,\nassuming the browser supports the RTP extension in the first place.\nIncoming RTP stream should provide abs-capture-time exactly in the same header id.\nabscapturetime_src_ext_id = 1\n\nThe following options are only valid for the 'rtsp' type:\nurl = RTSP stream URL\nrtsp_user = RTSP authorization username, if needed\nrtsp_pwd = RTSP authorization password, if needed\nrtsp_quirk = Some RTSP servers offer the stream using only the path, instead of the fully qualified URL.\n\tIf set true, this boolean informs Janus that we should try a path-only DESCRIBE request if the initial request returns 404.\nrtsp_failcheck = whether an error should be returned if connecting to the RTSP server fails (default=true)\nrtspiface = network interface IP address or device name to listen on when receiving RTSP streams\nrtsp_reconnect_delay = after n seconds passed and no media assumed, the RTSP server has gone and schedule a reconnect (default=5s)\nrtsp_session_timeout = by default the streaming plugin will check the RTSP connection with an OPTIONS query,\n\tthe value of the timeout comes from the RTSP session initializer and by default\n\tthis session timeout is the half of this value In some cases this value can be too high (for example more than one minute)\n\tbecause of the media server. In that case this plugin will calculate the timeout with this\n\tformula: timeout = min(session_timeout, rtsp_session_timeout / 2). (default=0s)\nrtsp_timeout = communication timeout (CURLOPT_TIMEOUT) for cURL call gathering the RTSP information (default=10s)\nrtsp_conn_timeout = connection timeout for cURL (CURLOPT_CONNECTTIMEOUT) call gathering the RTSP information (default=5s)\nrtsp_notify_changes = if set to true, will send an event to connected users when the RTSP session\n\tgets disconnected, and when it's reconnected (default=false)\n\\endverbatim\n *\n * Notice that attributes like \\c audioport or \\c videopt only make sense\n * when you're creating a mountpoint with a single audio and/or video stream,\n * as the plugin in that case assumes that limitation is fine by you. In\n * case you're interested in creating multistream mountpoints, that is\n * mountpoints that can contain more than one audio and/or video stream\n * at the same time, you HAVE to use a different syntax. Specifically,\n * you'll need to use a \\c media array/list, containing the different\n * streams, in the right order, that you want to make available: each\n * stream will then need to contain the related info, e.g., port to bind\n * to, type of media, codec name and so on. An example is provided below:\n *\n\\verbatim\nmultistream-test: {\n\ttype = \"rtp\"\n\tid = 123\n\tdescription = \"Multistream test (1 audio, 2 video)\"\n\tmedia = (\n\t\t{\n\t\t\ttype = \"audio\"\n\t\t\tmid = \"a\"\n\t\t\tlabel = \"Audio stream\"\n\t\t\tport = 5102\n\t\t\tpt = 111\n\t\t\tcodec = \"opus\"\n\t\t},\n\t\t{\n\t\t\ttype = \"video\"\n\t\t\tmid = \"v1\"\n\t\t\tlabel = \"Video stream #1\"\n\t\t\tport = 5104\n\t\t\tpt = 100\n\t\t\tcodec = \"vp8\"\n\t\t},\n\t\t{\n\t\t\ttype = \"video\"\n\t\t\tmid = \"v2\"\n\t\t\tlabel = \"Video stream #2\"\n\t\t\tport = 5106\n\t\t\tpt = 100\n\t\t\tcodec = \"vp8\"\n\t\t}\n\t)\n}\n\\endverbatim\n *\n * In the above example, we're creating a mountpoint with a single audio\n * stream and two different video streams: each stream has a unique \\c mid\n * (that you MUST provide) which is what will be used for the SDP offer\n * to send to viewers, and their unique configuration properties. As you\n * can see, it's much cleaner in the way you create and configure\n * mountpoints: there's no hardcoded audio/video prefix for the name of\n * properties, you configure media streams the same way and just add them\n * to a list. Notice that of course this also works with the simple one\n * audio/one video mountpoints you've used so far, and that has been\n * documented before: as such, you're encouraged to start using this\n * new approach as soon as possible, since in the next versions we\n * might deprecate the old one.\n *\n * \\section streamapi Streaming API\n *\n * The Streaming API supports several requests, some of which are\n * synchronous and some asynchronous. There are some situations, though,\n * (invalid JSON, invalid request) which will always result in a\n * synchronous error response even for asynchronous requests.\n *\n * \\c list , \\c info , \\c create , \\c destroy , \\c recording , \\c edit ,\n * \\c enable and \\c disable are synchronous requests, which means you'll\n * get a response directly within the context of the transaction. \\c list\n * lists all the available streams; \\c create allows you to create a new\n * mountpoint dynamically, as an alternative to using the configuration\n * file; \\c destroy removes a mountpoint and destroys it; \\c recording\n * instructs the plugin on whether or not a live RTP stream should be\n * recorded while it's broadcasted; \\c enable and \\c disable respectively\n * enable and disable a mountpoint, that is decide whether or not a\n * mountpoint should be available to users without destroying it.\n * \\c edit allows you to dynamically edit some mountpoint properties (e.g., the PIN);\n *\n * The \\c watch , \\c start , \\c configure , \\c pause , \\c switch and \\c stop requests\n * instead are all asynchronous, which means you'll get a notification\n * about their success or failure in an event. \\c watch asks the plugin\n * to prepare the playout of one of the available streams; \\c start\n * starts the actual playout; \\c pause allows you to pause a playout\n * without tearing down the PeerConnection; \\c switch allows you to\n * switch to a different mountpoint of the same kind (note: only live\n * RTP mountpoints supported as of now) without having to stop and watch\n * the new one; \\c stop stops the playout and tears the PeerConnection\n * down.\n *\n * Notice that, in general, all users can create mountpoints, no matter\n * what type they are. If you want to limit this functionality, you can\n * configure an admin \\c admin_key in the plugin settings. When\n * configured, only \"create\" requests that include the correct\n * \\c admin_key value in an \"admin_key\" property will succeed, and will\n * be rejected otherwise.\n *\n * \\subsection streamingsync Synchronous requests\n *\n * To list the available Streaming mountpoints (both those created via\n * configuration file and those created via API), you can use the \\c list\n * request:\n *\n\\verbatim\n{\n\t\"request\" : \"list\"\n}\n\\endverbatim\n *\n * If successful, it will return an array with a list of all the mountpoints.\n * Notice that only the public mountpoints will be returned: those with\n * an \\c is_private set to yes/true will be skipped. The response will\n * be formatted like this:\n *\n\\verbatim\n{\n\t\"streaming\" : \"list\",\n\t\"list\" : [\n\t\t{\n\t\t\t\"id\" : <unique ID of mountpoint #1>,\n\t\t\t\"type\" : \"<type of mountpoint #1, in line with the types introduced above>\",\n\t\t\t\"description\" : \"<description of mountpoint #1>\",\n\t\t\t\"metadata\" : \"<metadata of mountpoint #1, if any>\",\n\t\t\t\"enabled\" : <true|false, depending on whether the mountpoint is currently enabled or not>,\n\t\t\t\"media\" : [\n\t\t\t\t{\n\t\t\t\t\t\"mid\" : \"<unique mid of this stream>\",\n\t\t\t\t\t\"label\" : \"<unique text label of this stream>\",\n\t\t\t\t\t\"msid\" : \"<msid of this stream, if configured>\",\n\t\t\t\t\t\"type\" : \"<audio|video|data\">,\n\t\t\t\t\t\"age_ms\" : <how much time passed since we last received media for this stream; optional>,\n\t\t\t\t},\n\t\t\t\t{\n\t\t\t\t\t// Other streams, if available\n\t\t\t\t}\n\t\t\t]\n\t\t},\n\t\t{\n\t\t\t\"id\" : <unique ID of mountpoint #2>,\n\t\t\t\"type\" : \"<type of mountpoint #2, in line with the types introduced above>\",\n\t\t\t\"description\" : \"<description of mountpoint #2>\",\n\t\t\t\"metadata\" : \"<metadata of mountpoint #2, if any>\",\n\t\t\t\"media\" : [..]\n\t\t},\n\t\t...\n\t]\n}\n\\endverbatim\n *\n * As you can see, the \\c list request only returns very generic info on\n * each mountpoint.

Please refer to the documentation on\n * configuration files to see the fields you can pass. The only important\n * difference to highlight is that, unlike in configuration files, you will\n * NOT have to escape semicolons with a trailing slash, in those properties\n * where a semicolon might be needed (e.g., \\c audiofmtp or \\c videofmtp ).\n *\n * Notice that, just as we introduced the possibility of configuring multistream\n * mountpoints statically with a \\c media array, the same applies when using\n * the API to create them: just add a \\c media JSON array containing the\n * list of streams to create and the related properties as you would do\n * statically (that is, using generic properties like \\c port, \\c fmtp,\n * etc., rather than the hardcoded \\c audioport and the like), and it\n * will work for dynamically created mountpoints as well.\n *\n * A successful \\c create will result in a \\c created response:\n *\n\\verbatim\n{\n\t\"streaming\" : \"created\",\n\t\"create\" : \"<unique name of the just created mountpoint>\",\n\t\"permanent\" : <true|false, depending on whether the mountpoint was saved to configuration file or not>,\n\t\"stream\": {\n\t\t\"id\" : <unique ID of the just created mountpoint>,\n\t\t\"type\" : \"<type of the just created mountpoint>\",\n\t\t\"description\" : \"<description of the just created mountpoint>\",\n\t\t\"is_private\" : <true|false, depending on whether the new mountpoint is listable>,\n\t\t\"ports\" : [\t\t// Only for RTP mountpoints\n\t\t\t{\n\t\t\t\t\"type\" : \"<audio|video|data>\",\n\t\t\t\t\"mid\" : \"<unique mid of stream #1>\",\n\t\t\t\t\"msid\" : \"<msid of this stream, if configured>\",\n\t\t\t\t\"port\" : <port the plugin is listening on for this stream's media>\n\t\t\t},\n\t\t\t{\n\t\t\t\t// Other streams, if available\n\t\t\t}\n\t\t]\n\t\t...\n\t}\n}\n\\endverbatim\n *\n * Notice that additional information, namely the ports the mountpoint\n * bound to, will only be added for new RTP mountpoints, otherwise this\n * is all that a \\c created request will contain. If you want to double\n * check everything in your \\c create request went as expected, you may\n * want to issue a followup \\c info request to compare the results.\n *\n * Once you created a mountpoint, you can modify some (not all) of its\n * properties via an \\c edit request. Namely, you can only modify generic\n * properties like the mountpoint description, the secret, the PIN and\n * whether or not the mountpoint should be listable. All other properties\n * are considered to be immutable. Again, you can choose whether the changes\n * should be permanent, e.g., saved to configuration file, or not. Notice\n * that an \\c edit request requires the right secret to be provided, if\n * the mountpoint has one, or will return an error instead. The \\c edit\n * request must be formatted like this:\n *\n\\verbatim\n{\n\t\"request\" : \"edit\",\n\t\"id\" : <unique ID of the mountpoint to edit; mandatory>,\n\t\"secret\" : \"<secret to edit the mountpoint; mandatory if configured>\",\n\t\"new_description\" : \"<new description for the mountpoint; optional>\",\n\t\"new_metadata\" : \"<new metadata for the mountpoint; optional>\",\n\t\"new_secret\" : \"<new secret for the mountpoint; optional>\",\n\t\"new_pin\" : \"<new PIN for the mountpoint, PIN will be removed if set to an empty string; optional>\",\n\t\"new_is_private\" : <true|false, depending on whether the mountpoint should be now listable; optional>,\n\t\"permanent\" : <true|false, whether the mountpoint should be saved to configuration file or not; false by default>,\n\t\"edited_event\" : <true|false, whether an event will be sent to all viewers when metadata is updated; false by default>\n}\n\\endverbatim\n *\n * A successful \\c edit will result in an \\c edited response:\n *\n\\verbatim\n{\n\t\"streaming\" : \"edited\",\n\t\"id\" : <unique ID of the just edited mountpoint>,\n\t\"permanent\" : <true|false, depending on whether the changes were saved to configuration file or not>\n}\n\\endverbatim\n *\n * In case \\c edited_event was set to \\c true in the request, a successful \\c edit will\n * also result in an \\c edited event sent to all viewers when the metadata has changed:\n *\n\\verbatim\n{\n\t\"streaming\" : \"edited\",\n\t\"id\" : <unique ID of the just edited mountpoint>,\n\t\"metadata\" : \"<updated metadata for the mountpoint>\",\n}\n\\endverbatim\n *\n * Just as you can create and edit mountpoints, you can of course also destroy\n * them. Again, this applies to all mountpoints, whether created statically\n * via configuration file or dynamically via API, and the mountpoint destruction\n * can be made permanent in the configuration file as well. A \\c destroy\n * request must be formatted as follows:\n *\n\\verbatim\n{\n\t\"request\" : \"destroy\",\n\t\"id\" : <unique ID of the mountpoint to destroy; mandatory>,\n\t\"secret\" : \"<secret to destroy the mountpoint; mandatory if configured>\",\n\t\"permanent\" : <true|false, whether the mountpoint should be removed from the configuration file or not; false by default>\n}\n\\endverbatim\n *\n * If successful, the result will be confirmed in a \\c destroyed event:\n *\n\\verbatim\n{\n\t\"streaming\" : \"destroyed\",\n\t\"id\" : <unique ID of the just destroyed mountpoint>\n}\n\\endverbatim\n *\n * Notice that destroying a mountpoint while viewers are still subscribed\n * to it will result in all viewers being removed, and their PeerConnection\n * closed as a consequence.\n *\n * You can also dynamically enable and disable mountpoints via API. A\n * disabled mountpoint is a mountpoint that exists, and still works as\n * expected, but is not accessible to viewers until it's enabled again.\n * This is a useful property, especially in case of mountpoints that\n * need to be prepared in advance but must not be accessible until a\n * specific moment, and a much better alternative to just create the\n * mountpoint at the very last minute and destroy it otherwise. The\n * syntax for both the \\c enable and \\c disable requests is the same,\n * and looks like the following:\n *\n\\verbatim\n{\n\t\"request\" : \"enable\",\n\t\"id\" : <unique ID of the mountpoint to enable; mandatory>,\n\t\"secret\" : \"<secret to enable the mountpoint; mandatory if configured>\"\n}\n\\endverbatim\n *\n * If successful, a generic \\c ok is returned:\n *\n\\verbatim\n{\n\t\"streaming\" : \"ok\"\n}\n\\endverbatim\n\\verbatim\n{\n\t\"request\" : \"disable\",\n\t\"id\" : <unique ID of the mountpoint to disable; mandatory>,\n\t\"stop_recording\" : <true|false, whether the recording should also be stopped or not; true by default>\n\t\"secret\" : \"<secret to disable the mountpoint; mandatory if configured>\"\n}\n\\endverbatim\n *\n * If successful, a generic \\c ok is returned:\n *\n\\verbatim\n{\n\t\"streaming\" : \"ok\"\n}\n\\endverbatim\n *\n * You can kick all viewers from a mountpoint using the \\c kick_all request. Notice\n * that this only removes all viewers, but does not prevent them from starting to watch\n * the mountpoint again. Please note this request works with all mountpoint types,\n * except for on-demand streaming. The \\c kick_all request has to be formatted as follows:\n *\n\\verbatim\n{\n\t\"request\" : \"kick_all\",\n\t\"id\" : <unique ID of the mountpoint to disable; mandatory>,\n\t\"secret\" : \"<mountpoint secret; mandatory if configured>\",\n}\n\\endverbatim\n *\n * If successful, a \\c kicked_all response is returned:\n *\n\\verbatim\n{\n\t\"streaming\" : \"kicked_all\",\n}\n\\endverbatim\n *\n * Finally, you can record a mountpoint to the internal Janus .mjr format\n * using the \\c recording request. The same request can also be used to\n * stop recording. Although the same request is used in both cases, though,\n * the syntax for the two use cases differs a bit, namely in terms of the\n * type of some properties. Notice that, while for backwards compatibility\n * you can still use the old \\c audio, \\c video and \\c data named properties,\n * they're now deprecated and so you're highly encouraged to use the new drill-down\n * \\c media list instead.\n *\n * To start recording a new mountpoint, the request should be formatted\n * like this:\n *\n\\verbatim\n{\n\t\"request\" : \"recording\",\n\t\"action\" : \"start\",\n\t\"id\" : <unique ID of the mountpoint to manipulate; mandatory>,\n\t\"media\" : [\t\t// Drill-down recording controls\n\t\t{\n\t\t\t\"mid\" : \"<mid of the stream to start recording>\",\n\t\t\t\"filename\" : \"<base path/filename to use for the recording>\"\n\t\t},\n\t\t{\n\t\t\t// Recording controls for other streams, if provided\n\t\t}\n\t]\n}\n\\endverbatim\n *\n * To stop a recording, instead, this is the request syntax:\n *\n\\verbatim\n{\n\t\"request\" : \"recording\",\n\t\"action\" : \"stop\",\n\t\"id\" : <unique ID of the mountpoint to manipulate; mandatory>,\n\t\"media\" : [\t\t// Drill-down recording controls\n\t\t{\n\t\t\t\"mid\" : \"<mid of the stream to stop recording>\"\n\t\t},\n\t\t{\n\t\t\t// Recording controls for other streams, if provided\n\t\t}\n\t]\n}\n\\endverbatim\n *\n * When using the deprecated properties, when starting a recording the \\c audio ,\n * \\c video and \\c data properties are strings, and specify the base path\n * to use for the recording filename; when stopping a recording, instead,\n * they're interpreted as boolean properties. This is one more reason why\n * you should migrate to the new \\c media list instead, as it doesn't have\n * this ambiguity between the two different requests. Notice that, as with all\n * APIs that wrap .mjr recordings, the filename you specify here is not\n * the actual filename: an \\c .mjr extension is always going to be added\n * by the Janus core, so you should take this into account when tracking\n * the related recording files.\n *\n * Whether you started or stopped a recording, a successful request will\n * always result in a simple \\c ok response:\n *\n\\verbatim\n{\n\t\"streaming\" : \"ok\"\n}\n\\endverbatim\n *\n * \\subsection streamingasync Asynchronous requests\n *\n * All the requests we've gone through so far are synchronous. This means\n * that they return a response right away. That said, many of the requests\n * this plugin supports are asynchronous instead, which means Janus will\n * send an ack when they're received, and a response will only follow\n * later on. This is especially true for requests dealing with the\n * management and setup of mountpoint viewers, e.g., for the purpose of\n * negotiating a WebRTC PeerConnection to receive media from a mountpoint.\n *\n * To subscribe to a specific mountpoint, an interested viewer can make\n * use of the \\c watch request. As suggested by the request name, this\n * instructs the plugin to setup a new PeerConnection to allow the new\n * viewer to watch the specified mountpoint. The \\c watch request must\n * be formatted like this:\n *\n\\verbatim\n{\n\t\"request\" : \"watch\",\n\t\"id\" : <unique ID of the mountpoint to subscribe to; mandatory>,\n\t\"pin\" : \"<PIN required to access the mountpoint; mandatory if configured>\",\n\t\"media\" : [\n\t\t<array of mids to subscribe to, as strings; optional, missing or empty array subscribes to all mids>\n\t]\n\t\"offer_audio\" : <true|false; deprecated; whether or not audio should be negotiated; true by default if the mountpoint has audio>,\n\t\"offer_video\" : <true|false; deprecated; whether or not video should be negotiated; true by default if the mountpoint has video>,\n\t\"offer_data\" : <true|false; deprecated; whether or not datachannels should be negotiated; true by default if the mountpoint has datachannels>\n}\n\\endverbatim\n *\n * As you can see, it's just a matter of specifying the ID of the mountpoint to\n * subscribe to and, if needed, the PIN to access the mountpoint in case\n * it's protected. The \\c media array is particularly interesting, as it\n * allows you to only subscribe to a subset of the mountpoint media, which\n * you can address by the related \\c mid property of each stream. By default,\n * in fact, a \\c watch request will result in the plugin preparing a new\n * SDP offer trying to negotiate all the media streams available in the\n * mountpoint; in case the viewer knows they don't support one of the\n * mountpoint codecs, though (e.g., the video in the mountpoint is VP8,\n * but they only support H.264), or are not interested in getting all the\n * media (e.g., they're ok with just audio and not video, or don't have\n * enough bandwidth for both), they can use those properties to shape the\n * SDP offer to their needs. The \\c media array is optional, as a missing\n * or empty array will simply be interpreted as a willingness to subscribe\n * to all the streams in the mountpoint, which is the default behaviour.\n * Notice that the order of the mids in the \\c media array is irrelevant,\n * as is how many times the same mid is listed in the array: the presence\n * of a mid is just interpreted as an \"on\" switch for that stream, meaning\n * it will be offered in the SDP.\n *\n * \\note For backwards compatibility, the deprecated \\c offer_audio ,\n * \\c offer_video and \\c offer_data properties are also available. They\n * also allow you to only subscribe to a subset of the mountpoint media,\n * but with a more crude approach: specifically, they dictate whether or\n * not any audio, video or data stream should be offered or not.\n *\n * As anticipated, if successful this request will generate a new JSEP SDP\n * offer, which will be attached to a \\c preparing status event:\n *\n\\verbatim\n{\n\t\"status\" : \"preparing\"\n}\n\\endverbatim\n *\n * At this stage, to complete the setup of a subscription the viewer is\n * supposed to send a JSEP SDP answer back to the plugin. This is done\n * by means of a \\c start request, which in this case MUST be associated\n * with a JSEP SDP answer but otherwise requires no arguments:\n *\n\\verbatim\n{\n\t\"request\" : \"start\"\n}\n\\endverbatim\n *\n * If successful this request returns a \\c starting status event:\n *\n\\verbatim\n{\n\t\"status\" : \"starting\"\n}\n\\endverbatim\n *\n * Once this is done, all that's needed is waiting for the WebRTC PeerConnection\n * establishment to succeed. As soon as that happens, the Streaming plugin\n * can start relaying media from the mountpoint the viewer subscribed to\n * to the viewer themselves.\n *\n * Notice that the same exact steps we just went through (\\c watch request,\n * followed by JSEP offer by the plugin, followed by \\c start request with\n * JSEP answer by the viewer) is what you also use when renegotiations are\n * needed, e.g., for the purpose of ICE restarts.\n *\n * As a viewer, you can temporarily pause and resume the whole media delivery\n * with a \\c pause and, again, \\c start request (in this case without any JSEP\n * SDP answer attached). Neither expect other arguments, as the context\n * is implicitly derived from the handle they're sent on:\n *\n\\verbatim\n{\n\t\"request\" : \"pause\"\n}\n\\endverbatim\n *\n\\verbatim\n{\n\t\"request\" : \"start\"\n}\n\\endverbatim\n *\n * Unsurprisingly, they just result in, respectively, \\c pausing and\n * \\c starting events:\n *\n\\verbatim\n{\n\t\"status\" : \"pausing\"\n}\n\\endverbatim\n *\n\\verbatim\n{\n\t\"status\" : \"starting\"\n}\n\\endverbatim\n *\n * For more drill-down manipulations of a subscription, a \\c configure\n * request can be used instead. This request allows viewers to dynamically\n * change some properties associated to their media subscription, e.g.,\n * in terms of what should and should not be sent at a specific time. A\n * \\c configure request must be formatted as follows:\n *\n\\verbatim\n{\n\t\"request\" : \"configure\",\n\t\"streams\" : [\n\t\t{\n\t\t\t\"mid\" : <mid of the m-line to tweak>,\n\t\t\t\"send\" : <true|false, depending on whether the media addressed by the above mid should be relayed or not; optional>,\n\t\t\t\"substream\" : <substream to receive (0-2), in case simulcasting is enabled; optional>,\n\t\t\t\"temporal\" : <temporal layers to receive (0-2), in case simulcasting is enabled; optional>,\n\t\t\t\"fallback\" : <How much time (in us, default 250000) without receiving packets will make us drop to the substream below>,\n\t\t\t\"spatial_layer\" : <spatial layer to receive (0-1), in case VP9-SVC is enabled; optional>,\n\t\t\t\"temporal_layer\" : <temporal layers to receive (0-2), in case VP9-SVC is enabled; optional>,\n\t\t\t\"min_delay\" : <minimum delay to enforce via the playout-delay RTP extension, in blocks of 10ms; optional>,\n\t\t\t\"max_delay\" : <maximum delay to enforce via the playout-delay RTP extension, in blocks of 10ms; optional>\n\t\t},\n\t\t// Other streams, if any\n\t]\n}\n\\endverbatim\n *\n * While the deprecated \\c audio , \\c video and \\c data properties can still be\n * used as a media-level pause/resume functionality, a better option is to\n * specify the \\c mid of the stream instead, and a \\c send boolean property\n * to specify if this specific stream should be relayed or not. The \\c pause\n * and \\c start requests instead pause and resume all streams at the same time.\n * The \\c substream and \\c temporal properties, finally, only make sense\n * when the mountpoint is configured with video simulcasting support, and\n * as such the viewer is interested in receiving a specific substream\n * or temporal layer, rather than any other of the available ones.\n * The \\c spatial_layer and \\c temporal_layer have exactly the same meaning,\n * but within the context of VP9-SVC mountpoints, and will have no effect\n * on mountpoints involving a different video codec. In both cases, make\n * sure you specify the \\c mid of the stream in case multiple videos are\n * available in a mountpoint, or the request may have no effect.\n *\n * Another interesting feature in the Streaming plugin is the so-called\n * mountpoint \"switching\". Basically, when subscribed to a specific\n * mountpoint and receiving media from there, you can at any time \"switch\"\n * to a different mountpoint, and as such start receiving media from that\n * other mountpoint instead. Think of it as changing channel on a TV: you\n * keep on using the same PeerConnection, the plugin simply changes the\n * source of the media transparently. Of course, while powerful and effective\n * this request has some limitations. First of all, it only works with RTP\n * mountpoints, and not other mountpoint types; besides, the two mountpoints\n * must have the same media configuration, that is, use the same codecs,\n * the same payload types, etc. In fact, since the same PeerConnection is\n * used for this feature, switching to a mountpoint with a different\n * configuration might result in media incompatible with the PeerConnection\n * setup being relayed to the viewer, and as such in no audio/video being\n * played. That said, a \\c switch request must be formatted like this:\n *\n\\verbatim\n{\n\t\"request\" : \"switch\",\n\t\"id\" : <unique ID of the new mountpoint to switch to; mandatory>\n}\n\\endverbatim\n *\n * If successful, you'll be unsubscribed from the previous mountpoint,\n * and subscribed to the new mountpoint instead. The event to confirm\n * the switch was successful will look like this:\n *\n\\verbatim\n{\n\t\"switched\" : \"ok\",\n\t\"id\" : <unique ID of the new mountpoint>\n}\n\\endverbatim\n *\n * Finally, to stop the subscription to the mountpoint and tear down the\n * related PeerConnection, you can use the \\c stop request. Since context\n * is implicit, no other argument is required:\n *\n\\verbatim\n{\n\t\"request\" : \"stop\"\n}\n\\endverbatim\n *\n * If successful, the plugin will attempt to tear down the PeerConnection,\n * and will send back a \\c stopping status event:\n *\n\\verbatim\n{\n\t\"status\" : \"stopping\"\n}\n\\endverbatim\n *\n * Once a PeerConnection has been torn down and the subscription closed,\n * as a viewer you're free to subscribe to a different mountpoint instead.\n * In fact, while you can't watch more than one mountpoint at the same\n * time on the same handle, there's no limit on how many mountpoints\n * you can watch in sequence, again on the same handle. If you're interested\n * in subscribing to multiple mountpoints at the same time, instead, you'll\n * have to create multiple handles for the purpose.\n */\n\n\n#include \"plugin.h\"\n\n#include <errno.h>\n#include <netdb.h>\n#include <sys/poll.h>\n#include <sys/socket.h>\n#include <sys/time.h>\n\n#include <jansson.h>\n\n#ifdef HAVE_LIBCURL\n#include <curl/curl.h>\n#ifndef CURL_AT_LEAST_VERSION\n#define CURL_AT_LEAST_VERSION(x,y,z) 0\n#endif\n#endif\n\n#ifdef HAVE_LIBOGG\n#include <ogg/ogg.h>\n#endif\n\n#include \"../debug.h\"\n#include \"../apierror.h\"\n#include \"../config.h\"\n#include \"../mutex.h\"\n#include \"../rtp.h\"\n#include \"../rtpsrtp.h\"\n#include \"../rtcp.h\"\n#include \"../record.h\"\n#include \"../utils.h\"\n#include \"../sdp-utils.h\"\n#include \"../ip-utils.h\"\n\n/* Default settings */\n#define JANUS_STREAMING_DEFAULT_SESSION_TIMEOUT 0 /* Overwrite the RTSP session timeout.

    "content": "/*! \\file   janus_textroom.c\n * \\author Lorenzo Miniero <lorenzo@meetecho.com>\n * \\copyright GNU General Public License v3\n * \\brief  Janus TextRoom plugin\n * \\details Check the \\ref textroom for more details.\n *\n * \\ingroup plugins\n * \\ref plugins\n *\n * \\page textroom Janus TextRoom documentation\n * This is a plugin implementing a DataChannel only text room.\n * As such, it does NOT support or negotiate audio or video, but only\n * data channels, in order to provide text broadcasting features. The\n * plugin allows users to join multiple text-only rooms via a single\n * PeerConnection. Users can send messages either to a room in general\n * (broadcasting), or to individual users (whispers). This plugin can be\n * used within the context of any application that needs real-time text\n * broadcasting (e.g., chatrooms, but not only).\n *\n * The only message that is typically sent to the plugin through the Janus API is\n * a \\c setup message, by which the user initializes the PeerConnection\n * itself, as explained in the \\ref textroomsetup section.\n * Apart from that, all other messages can be exchanged directly\n * via Data Channels. For room management purposes, though, requests like\n * \\c create , \\c edit , \\c destroy , \\c list , \\c listparticipants , \\c exists\n * and \\c announcement are available through the\n * Janus API as well: notice that in this case you'll have to use \\c request\n * and not \\c textroom as the name of the request. You cannot join a room\n * or send/receive messages via Janus API: that's only possible through\n * the datachannel interface.\n *\n * Each room can also be configured with an HTTP backend to contact for\n * incoming messages. If configured, messages addressed to that room will\n * also be forwarded, by means of an HTTP POST, to the specified address.\n * Notice that this will only work if libcurl was available when\n * configuring and installing Janus.\n *\n * \\note This plugin is only meant to showcase what you can do with\n * data channels involving multiple participants at the same time. While\n * functional, it's not inherently better or faster than doing the same\n * thing using the Janus API messaging itself (e.g., as part of the\n * plugin API messaging) or using existing instant messaging protocols\n * (e.g., Jabber). In fact, while data channels are being used, you're\n * still going through a server, so it's not really peer-to-peer. That\n * said, the plugin can be useful if you don't plan to use any other\n * infrastructure than Janus, and yet you also want to have text-based\n * communication (e.g., to add a chatroom to an audio or video conference).\n *\n * Notice that, in general, all users can create rooms. If you want to\n * limit this functionality, you can configure an admin \\c admin_key in\n * the plugin settings. When configured, only \"create\" requests that\n * include the correct \\c admin_key value in an \"admin_key\" property\n * will succeed, and will be rejected otherwise.\n *\n * Rooms to make available at startup are listed in the plugin configuration file.\n * A pre-filled configuration file is provided in \\c conf/janus.plugin.textroom.cfg\n * and includes a demo room for testing.\n *\n * To add more static rooms or modify the existing one, you can use the following\n * syntax:\n *\n * \\verbatim\n[<unique room ID>]\ndescription = This is my awesome room\nis_private = true|false (whether this room should be in the public list, default=true)\nsecret = <optional password needed for manipulating (e.g. destroying) the room>\npin = <optional password needed for joining the room>\nhistory = <number of messages to store as a history, and send back to new participants (default=0, no history)>\npost = <optional backend to contact via HTTP post for all incoming messages>\n\\endverbatim\n *\n * As explained in the next sections, you can also create rooms programmatically.\n *\n * \\section textroomsetup Establishing a connection\n *\n * While some requests to the plugin can be sent via Janus API, the actual\n * chatroom functionality is only available via datachannel. This means\n * that you need to establish a WebRTC PeerConnection first, if you want\n * to take full advantage of the functionality provided by the TextRoom plugin.\n *\n * To do that, you use the \\c setup request, which doesn't require any\n * argument:\n *\n\\verbatim\n{\n\t\"request\" : \"setup\"\n}\n\\endverbatim\n *\n * Assuming a datachannel wasn't established already, the plugin will\n * react to that request with a basic event, which will contain a JSEP\n * offer too:\n *\n\\verbatim\n{\n\t\"textroom\" : \"event\",\n\t\"result\" : \"ok\"\n}\n\\endverbatim\n *\n * To complete the negotiation process and establish a WebRTC PeerConnection,\n * you need to send an empty \\c ack request with your JSEP answer:\n *\n\\verbatim\n{\n\t\"request\" : \"ack\"\n}\n\\endverbatim\n *\n * Should you need to perform an ICE restart, e.g., to keep the datachannel\n * alive during a connection migration, you can use an empty \\c restart\n * request:\n *\n\\verbatim\n{\n\t\"request\" : \"restart\"\n}\n\\endverbatim\n *\n * Just as in the \\c setup request, this will result in the plugin sending\n * a new JSEP offer with an attempt to restart ICE. You can use the\n * \\c ack request to provide your JSEP answer in this case too.\n *\n * Once the datachannel is active, you can start exchanging messages\n * there, referring to the \\ref textroomapi for the syntax. As explained\n * in the intro, some request described there can be sent over Janus API\n * too, but you'll need to use \\c request instead of \\c textroom as the\n * name of the request.\n *\n * \\section textroomapi Text Room API\n *\n * All TextRoom API requests sent via datachannels are addressed by a \\c textroom named property,\n * and must contain a \\c transaction string property as well, which will\n * be returned in the response. Notice that, for the sake of brevity, the\n * \\c transaction property will not be displayed in the documentation,\n * although, as explained, it MUST be present, and WILL be included in\n * all responses (but not in the unsolicited events, like join/leave\n * or incoming messages).\n *\n * To get a list of the available rooms (excluded those configured or\n * created as private rooms) you can make use of the \\c list request,\n * which has to be formatted as follows:\n *\n\\verbatim\n{\n\t\"textroom\" : \"list\",\n\t\"admin_key\" : \"<plugin administrator key; optional>\"\n}\n\\endverbatim\n *\n * A successful request will produce a list of rooms in a \\c success response:\n *\n\\verbatim\n{\n\t\"textroom\" : \"success\",\n\t\"list\" : [\t\t// Array of room objects\n\t\t{\t// Room #1\n\t\t\t\"room\" : <unique numeric ID>,\n\t\t\t\"description\" : \"<Name of the room>\",\n\t\t\t\"pin_required\" : <true|false, depending on whether the room is PIN-protected>,\n\t\t\t\"num_participants\" : <count of the participants>,\n\t\t\t\"history\" : <size of history, if any>\n\t\t},\n\t\t// Other rooms\n\t]\n}\n\\endverbatim\n *\n * To get a list of the participants in a specific room, instead, you\n * can make use of the \\c listparticipants request, which has to be\n * formatted as follows:\n *\n\\verbatim\n{\n\t\"request\" : \"listparticipants\",\n\t\"room\" : <unique numeric ID of the room>\n}\n\\endverbatim\n *\n * A successful request will produce a list of participants in a\n * \\c participants response:\n *\n\\verbatim\n{\n\t\"textroom\" : \"success\",\n\t\"room\" : <unique numeric ID of the room>,\n\t\"participants\" : [\t\t// Array of participant objects\n\t\t{\t// Participant #1\n\t\t\t\"username\" : \"<username of participant>\",\n\t\t\t\"display\" : \"<display name of participant, if any>\"\n\t\t},\n\t\t// Other participants\n\t]\n}\n\\endverbatim\n *\n * To create new TextRoom rooms you can use the \\c create request. The API\n * room creation supports the same fields as creation via configuration files,\n * which means the request must be formatted as follows:\n *\n\\verbatim\n{\n\t\"textroom\" : \"create\",\n\t\"room\" : <unique numeric room ID to assign; optional, chosen by plugin if missing>,\n\t\"admin_key\" : \"<plugin administrator key; mandatory if configured>\",\n\t\"description\" : \"<description of room; optional>\",\n\t\"secret\" : \"<secret to query/edit the room later; optional>\",\n\t\"pin\" : \"<PIN required for participants to join room; optional>\",\n\t\"is_private\" : <true|false, whether the room should be listable; optional, true by default>,\n\t\"history\" : <number of messages to store as a history, and send back to new participants (default=0, no history)>,\n\t\"post\" : \"<backend to contact via HTTP post for all incoming messages; optional>\",\n\t\"permanent\" : <true|false, whether the mountpoint should be saved to configuration file or not; false by default>\n}\n\\endverbatim\n *\n * A successful creation procedure will result in a \\c success response:\n *\n\\verbatim\n{\n\t\"textroom\" : \"success\",\n\t\"room\" : <unique numeric ID>,\n\t\"permanent\" : <true if saved to config file, false if not>\n}\n\\endverbatim\n *\n * If you requested a permanent room but a \\c false value is returned\n * instead, good chances are that there are permission problems.\n *\n * An error instead (and the same applies to all other requests, so this\n * won't be repeated) would provide both an error code and a more verbose\n * description of the cause of the issue:\n *\n\\verbatim\n{\n\t\"textroom\" : \"event\",\n\t\"error_code\" : <numeric ID, check Macros below>,\n\t\"error\" : \"<error description as a string>\"\n}\n\\endverbatim\n *\n * Once a room has been created, you can still edit some (but not all)\n * of its properties using the \\c edit request. This allows you to modify\n * the room description, secret, pin, whether it's private or not and\n * the backend to forward incoming messages to: you won't be able to modify\n * other more static properties, though, like the room ID for instance.\n * If you're interested in changing the ACL, instead, check the \\c allowed\n * message. An \\c edit request has to be formatted as follows:\n *\n\\verbatim\n{\n\t\"textroom\" : \"edit\",\n\t\"room\" : <unique numeric ID of the room to edit; mandatory>,\n\t\"secret\" : \"<room secret; mandatory if configured>\",\n\t\"new_description\" : \"<new pretty name of the room; optional>\",\n\t\"new_secret\" : \"<new password required to edit/destroy the room; optional>\",\n\t\"new_pin\" : \"<new password required to join the room; optional>\",\n\t\"new_is_private\" : <true|false, whether the room should appear in a list request; optional>,\n\t\"permanent\" : <true|false, whether the room should be also removed from the config file; default=false>\n}\n\\endverbatim\n *\n * A successful edit procedure will result in a \\c success response:\n *\n\\verbatim\n{\n\t\"textroom\" : \"edited\",\n\t\"room\" : <unique numeric ID>,\n\t\"permanent\" : <true if changes were saved to config file, false if not>\n}\n\\endverbatim\n *\n * On the other hand, \\c destroy can be used to destroy an existing text\n * room, whether created dynamically or statically, and has to be\n * formatted as follows:\n *\n\\verbatim\n{\n\t\"textroom\" : \"destroy\",\n\t\"room\" : <unique numeric ID of the room to destroy; mandatory>,\n\t\"secret\" : \"<room secret; mandatory if configured>\",\n\t\"permanent\" : <true|false, whether the room should be also removed from the config file; default=false>\n}\n\\endverbatim\n *\n * A successful destruction procedure will result in a \\c destroyed response:\n *\n\\verbatim\n{\n\t\"textroom\" : \"destroyed\",\n\t\"room\" : <unique numeric ID>,\n\t\"permanent\" : <true if the room was removed from config file too, false if not>\n}\n\\endverbatim\n *\n * This will also result in a \\c destroyed event being sent to all the\n * participants in the room, which will look like this:\n *\n\\verbatim\n{\n\t\"textroom\" : \"destroyed\",\n\t\"room\" : <unique numeric ID of the destroyed room>\n}\n\\endverbatim\n *\n * You can check whether a room exists using the \\c exists request,\n * which has to be formatted as follows:\n *\n\\verbatim\n{\n\t\"textroom\" : \"exists\",\n\t\"room\" : <unique numeric ID of the room to check; mandatory>\n}\n\\endverbatim\n *\n * A successful request will result in a \\c success response:\n *\n\\verbatim\n{\n\t\"textroom\" : \"success\",\n\t\"room\" : <unique numeric ID>,\n\t\"exists\" : <true|false>\n}\n\\endverbatim\n *\n * You can configure whether to check tokens or add/remove people who can join\n * a room using the \\c allowed request, which has to be formatted as follows:\n *\n\\verbatim\n{\n\t\"textroom\" : \"allowed\",\n\t\"secret\" : \"<room secret; mandatory if configured>\",\n\t\"action\" : \"enable|disable|add|remove\",\n\t\"room\" : <unique numeric ID of the room to update; mandatory>,\n\t\"allowed\" : [\n\t\t// Array of strings (tokens users might pass in \"join\", only for add|remove)\n\t]\n}\n\\endverbatim\n *\n * A successful request will result in a \\c success response:\n *\n\\verbatim\n{\n\t\"textroom\" : \"success\",\n\t\"room\" : <unique numeric ID>,\n\t\"allowed\" : [\n\t\t// Updated, complete, list of allowed tokens (only for enable|add|remove)\n\t]\n}\n\\endverbatim\n *\n * If you're the administrator of a room (that is, you created it and have access\n * to the secret) you can kick participants using the \\c kick request. Notice\n * that this only kicks the user out of the room, but does not prevent them from\n * re-joining: to ban them, you need to first remove them from the list of\n * authorized users (see \\c allowed request) and then \\c kick them. The \\c kick\n * request has to be formatted as follows:\n *\n\\verbatim\n{\n\t\"textroom\" : \"kick\",\n\t\"secret\" : \"<room secret; mandatory if configured>\",\n\t\"room\" : <unique numeric ID of the room; mandatory>,\n\t\"username\" : \"<unique username of the participant to kick; mandatory>\"\n}\n\\endverbatim\n *\n * A successful request will result in a \\c success response:\n *\n\\verbatim\n{\n\t\"textroom\" : \"success\",\n}\n\\endverbatim\n *\n * This will also result in a \\c kicked event being sent to all the other\n * participants in the room, which will look like this:\n *\n\\verbatim\n{\n\t\"textroom\" : \"kicked\",\n\t\"room\" : <unique numeric ID of the room>,\n\t\"username\" : \"<unique username of the kicked participant>\"\n}\n\\endverbatim\n *\n * For what concerns room participation, you can join a room using the\n * \\c join request, send messages (public and private) using the\n * \\c message request, and leave a room with \\c leave instead.\n *\n * A \\c join request must be formatted as follows:\n *\n\\verbatim\n{\n\t\"textroom\" : \"join\",\n\t\"room\" : <unique numeric ID of the room to join>,\n\t\"pin\" : \"<pin to join the room; mandatory if configured>\",\n\t\"username\" : \"<unique username to have in the room; mandatory>\",\n\t\"display\" : \"<display name to use in the room; optional>\",\n\t\"token\" : \"<invitation token, in case the room has an ACL; optional>\",\n\t\"history\" : <true|false, whether to retrieve history messages when available (default=true)>\n}\n\\endverbatim\n *\n * A successful join will result in a \\c success response, which will\n * include a list of all the other participants currently in the room:\n *\n\\verbatim\n{\n\t\"textroom\" : \"success\",\n\t\"participants\" : [\n\t\t{\n\t\t\t\"username\" : \"<username of participant #1>\",\n\t\t\t\"display\" : \"<display name of participant #1, if any>\"\n\t\t},\n\t\t// Other participants\n\t]\n}\n\\endverbatim\n *\n * As explained previously, there's no hardcoded limit in how many rooms\n * you can join with the same participant and on the same PeerConnection.\n *\n * Notice that a successful \\c join request will also result in a\n * \\c join event being sent to all the other participants, so that\n * they're notified about the new participant getting in the room:\n *\n\\verbatim\n{\n\t\"textroom\" : \"join\",\n\t\"room\" : <room ID>,\n\t\"username\" : \"<username of new participant>\",\n\t\"display\" : \"<display name of new participant, if any>\"\n}\n\\endverbatim\n *\n * To leave a previously joined room, instead, the \\c leave request can\n * be used, which must be formatted like this:\n *\n\\verbatim\n{\n\t\"textroom\" : \"leave\",\n\t\"room\" : <unique numeric ID of the room to leave>\n}\n\\endverbatim\n *\n * A successful leave will result in a \\c success response:\n *\n\\verbatim\n{\n\t\"textroom\" : \"success\"\n}\n\\endverbatim\n *\n * Notice that a successful \\c leave request will also result in a\n * \\c leave event being sent to all the other participants, so that\n * they're notified about the participant that just left the room:\n *\n\\verbatim\n{\n\t\"textroom\" : \"leave\",\n\t\"room\" : <room ID>,\n\t\"username\" : \"<username of gone participant>\"\n}\n\\endverbatim\n *\n * Finally, the \\c message request allows you to send public and private\n * messages within the context of a room. It must be formatted like this:\n *\n\\verbatim\n{\n\t\"textroom\" : \"message\",\n\t\"room\" : <unique numeric ID of the room this message will refer to>,\n\t\"to\" : \"<username to send the message to; optional, only needed in case of private messages>\",\n\t\"tos\" : \"<array of usernames to send the message to; optional, only needed in case of private messages>\",\n\t\"text\" : \"<content of the message to send, as a string>\",\n\t\"ack\" : <true|false, whether the sender wants an ack for the sent message(s); optional, true by default>\n}\n\\endverbatim\n *\n * A \\c message with no \\c to and no \\c tos is considered a public message,\n * and so will be sent to all the participants in the room. In case either\n * \\c to or \\c tos is specified, instead, this is considered to be a whisper,\n * that is a private message only meant for the specified recipients. Notice\n * that \\c to and \\c tos are mutually exclusive, and you cannot specify both.\n *\n * \\c text must be a string, but apart from that there's no limit on what\n * you can put in there. It could be, for instance, a serialized JSON string,\n * or a stringified XML document, or whatever makes sense to the application.\n *\n * A successful message delivery will result in a \\c success response, but\n * only if \\c ack was \\c true in the \\c message request. This was done by\n * design, to allow users to disable explicit acks for every outgoing message,\n * especially in case of verbose communications. In case an ack is required,\n * the response will look like this:\n *\n\\verbatim\n{\n\t\"textroom\" : \"success\"\n}\n\\endverbatim\n *\n * Incoming messages will come either as \\c message events. In particular,\n * \\c message will notify the user about an incoming public or privave\n * message, that is either a message that was sent to the whole room,\n * or to the user individually:\n *\n\\verbatim\n{\n\t\"textroom\" : \"message\",\n\t\"room\" : <room ID the message was sent to>,\n\t\"from\" : \"<username of participant who sent the public message>\",\n\t\"date\" : \"<date/time of when the message was sent>\",\n\t\"text\" : \"<content of the message>\",\n\t\"whisper\" : <true|false, depending on whether it's a public or private message>\n}\n\\endverbatim\n *\n * In case the \\c whisper attribute is \\c true it means the user actually\n * received a  private message from another participant in the room.\n *\n * Another way of injecting text into rooms is by means of announcements.\n * Announcements are basically messages sent by the room itself, rather\n * than individual users: as such, only users or applications managing\n * the room can send these announcements, as the room secret will be\n * required for the purpose. The \\c announcement request implements this\n * feature in the TextRoom plugin, and must be formatted like this:\n *\n\\verbatim\n{\n\t\"textroom\" : \"announcement\",\n\t\"room\" : <unique numeric ID of the room this announcement will be sent to>,\n\t\"secret\" : \"<room secret; mandatory if configured>\",\n\t\"text\" : \"<content of the announcement to send, as a string>\"\n}\n\\endverbatim\n *\n * In case the \\c announcement request is accepted, the response will look\n * like this:\n *\n\\verbatim\n{\n\t\"textroom\" : \"success\"\n}\n\\endverbatim\n *\n * Incoming announcements will be received by participants as \\c announcement\n * events. The syntax is pretty much identical to how \\c message looks like,\n * with the difference that no \\c from attribute will be included as the\n * announcement will be seen as coming from the room itself:\n *\n\\verbatim\n{\n\t\"textroom\" : \"announcement\",\n\t\"room\" : <room ID the announcement was sent to>,\n\t\"date\" : \"<date/time of when the announcement was sent>\",\n\t\"text\" : \"<content of the announcement>\"\n}\n\\endverbatim\n *\n */\n\n#include \"plugin.h\"\n\n#include <jansson.h>\n\n#ifdef HAVE_LIBCURL\n#include <curl/curl.h>\n#endif\n\n#include

The idea is to\n * provide a similar service as the at the time well known (and now\n * discontinued) AppRTC demo (https://github.com/webrtc/apprtc),\n * but with the media flowing through a server rather than being peer-to-peer.\n *\n * The plugin provides a simple fake registration mechanism. A peer attaching\n * to the plugin needs to specify a username, which acts as a \"phone number\":\n * if the username is free, it is associated with the peer, which means\n * he/she can be \"called\" using that username by another peer. Peers can\n * either \"call\" another peer, by specifying their username, or wait for a call.\n * The approach used by this plugin is similar to the one employed by the\n * echo test one: all frames (RTP/RTCP) coming from one peer are relayed\n * to the other.\n *\n * Just as in the janus_videocall.c plugin, there are knobs to control\n * whether audio and/or video should be muted or not, and if the bitrate\n * of the peer needs to be capped by means of REMB messages.\n *\n * \\section vcallapi Video Call API\n *\n * All requests you can send in the Video Call API are asynchronous,\n * which means all responses (successes and errors) will be delivered\n * as events with the same transaction.\n *\n * The supported requests are \\c list , \\c register , \\c call ,\n * \\c accept , \\c set and \\c hangup . \\c list allows you to get a list\n * of all the registered peers; \\c register can be used to register\n * a username to call and be called; \\c call is used to start a video\n * call with somebody through the plugin, while \\c accept is used to\n * accept the call in case one is invited instead of inviting; \\c set\n * can be used to configure some call-related settings (e.g., a cap on\n * the send bandwidth); finally, \\c hangup can be used to terminate the\n * communication at any time, either to hangup an ongoing call or to\n * cancel/decline a call that hasn't started yet.\n *\n * The \\c list request has to be formatted as follows:\n *\n\\verbatim\n{\n\t\"request\" : \"list\"\n}\n\\endverbatim\n *\n * A successful request will result in an array of peers to be returned:\n *\n\\verbatim\n{\n\t\"videocall\" : \"event\",\n\t\"result\" : {\n\t\t\"list\": [\t// Array of peers\n\t\t\t\"alice78\",\n\t\t\t\"bob51\",\n\t\t\t// others\n\t\t]\n\t}\n}\n\\endverbatim\n *\n * An error instead (and the same applies to all other requests, so this\n * won't be repeated) would provide both an error code and a more verbose\n * description of the cause of the issue:\n *\n\\verbatim\n{\n\t\"videocall\" : \"event\",\n\t\"error_code\" : <numeric ID, check Macros below>,\n\t\"error\" : \"<error description as a string>\"\n}\n\\endverbatim\n *\n * To register a username to call and be called, the \\c register request\n * can be used. This works on a \"first come, first served\" basis: there's\n * no authentication involved, you just specify the username you'd like\n * to use and, if free, it's assigned to you. Notice that there's no\n * way to unregister: you have to close the handle to free the username.\n * The \\c register request has to be formatted as follows:\n *\n\\verbatim\n{\n\t\"request\" : \"register\",\n\t\"username\" : \"<desired unique username>\"\n}\n\\endverbatim\n *\n * If successful, this will result in a \\c registered event:\n *\n\\verbatim\n{\n\t\"videocall\" : \"event\",\n\t\"result\" : {\n\t\t\"event\" : \"registered\",\n\t\t\"username\" : \"<same username, registered>\"\n\t}\n}\n\\endverbatim\n *\n * Once you're registered, you can either start a new call or wait to\n * be called by someone else who knows your username. To start a new\n * call, the \\c call request can be used: this request must be attached\n * to a JSEP offer containing the WebRTC-related info to setup a new\n * media session. A \\c call request has to be formatted as follows:\n *\n\\verbatim\n{\n\t\"request\" : \"call\",\n\t\"username\" : \"<username to call>\"\n}\n\\endverbatim\n *\n * If successful, this will result in a \\c calling event:\n *\n\\verbatim\n{\n\t\"videocall\" : \"event\",\n\t\"result\" : {\n\t\t\"event\" : \"calling\",\n\t\t\"username\" : \"<same username, registered>\"\n\t}\n}\n\\endverbatim\n *\n * At the same time, the user being called will receive an\n * \\c incomingcall event\n *\n\\verbatim\n{\n\t\"videocall\" : \"event\",\n\t\"result\" : {\n\t\t\"event\" : \"incomingcall\",\n\t\t\"username\" : \"<your username>\"\n\t}\n}\n\\endverbatim\n *\n * To accept the call, the \\c accept request can be used. This request\n * must be attached to a JSEP answer containing the WebRTC-related\n * information to complete the actual PeerConnection setup. A \\c accept\n * request has to be formatted as follows:\n *\n\\verbatim\n{\n\t\"request\" : \"accept\"\n}\n\\endverbatim\n *\n * If successful, both the caller and the callee will receive an\n * \\c accepted event to notify them about the success of the signalling:\n *\n\\verbatim\n{\n\t\"videocall\" : \"event\",\n\t\"result\" : {\n\t\t\"event\" : \"accepted\",\n\t\t\"username\" : \"<caller username>\"\n\t}\n}\n\\endverbatim\n *\n * At this point, the media-related settings of the call can be modified\n * on either side by means of a \\c set request, which acts pretty much\n * as the one in the \\ref echoapi . The \\c set request has to be\n * formatted as follows. All the attributes (except \\c request) are\n * optional, so any request can contain a subset of them:\n *\n\\verbatim\n{\n\t\"request\" : \"set\",\n\t\"audio\" : true|false,\n\t\"video\" : true|false,\n\t\"bitrate\" : <numeric bitrate value>,\n\t\"record\" : true|false,\n\t\"filename\" : <base path/filename to use for the recording>,\n\t\"substream\" : <substream to receive (0-2), in case simulcasting is enabled>,\n\t\"temporal\" : <temporal layers to receive (0-2), in case simulcasting is enabled>,\n\t\"fallback\" : <How much time (in us, default 250000) without receiving packets will make us drop to the substream below>\n}\n\\endverbatim\n *\n * \\c audio instructs the plugin to do or do not relay audio frames;\n * \\c video does the same for video; \\c bitrate caps the bandwidth to\n * force on the browser encoding side (e.g., 128000 for 128kbps);\n * \\c record enables or disables the recording of this peer; in case\n * recording is enabled, \\c filename allows to specify a base\n * path/filename to use for the files (-audio.mjr, -video.mjr and -data.mjr\n * are automatically appended). Beware that enabling the recording only\n * records this user's contribution, and not the whole call: to record\n * both sides, you need to enable recording for both the peers in the\n * call. Finally, in case the call uses simulcasting, \\c substream and\n * \\c temporal can be used to manually pick which substream and/or temporal\n * layer should be received from the peer.\n *\n * A successful request will result in a \\c set event:\n *\n\\verbatim\n{\n\t\"videocall\" : \"event\",\n\t\"result\" : {\n\t\t\"event\" : \"set\"\n\t}\n}\n\\endverbatim\n *\n * Notice that the \\c set request is also what you use when you want\n * to renegotiate a session, e.g., for the purpose of adding/removing\n * media streams or forcing an ICE restart. In that case, even an empty\n * \\c set request is fine, as long as it accompanies a new JSEP offer\n * or answer (depending on who originated the session update). The user\n * receiving the updated JSEP offer/answer will get an \\c update event:\n *\n\\verbatim\n{\n\t\"videocall\" : \"event\",\n\t\"result\" : {\n\t\t\"event\" : \"update\",\n\t}\n}\n\\endverbatim\n *\n * To decline an incoming call, cancel an attempt to call or simply\n * hangup an ongoing conversation, the \\c hangup request can be used,\n * which has to be formatted as follows:\n *\n\\verbatim\n{\n\t\"request\" : \"hangup\"\n}\n\\endverbatim\n *\n * Whatever the reason of a call being closed (e.g., a \\c hangup request,\n * a PeerConnection being closed, or something else), both parties in\n * the communication will receive a \\c hangup event:\n *\n\\verbatim\n{\n\t\"videocall\" : \"event\",\n\t\"result\" : {\n\t\t\"event\" : \"hangup\",\n\t\t\"username\" : \"<username of who closed the communication>\",\n\t\t\"reason\" : \"<description of what happened>\"\n\t}\n}\n\\endverbatim\n */\n\n#include \"plugin.h\"\n\n#include

This room is based on a Publish/Subscribe\n * pattern. Each peer can publish his/her own live audio/video feeds: this\n * feed becomes an available stream in the room the other participants can\n * subscribe to. This means that this plugin allows the realization of several\n * different scenarios, ranging from a simple webinar (one speaker, several\n * watchers) to a fully meshed video conference (each peer sending and\n * receiving to and from all the others).\n *\n * Notice that, since Janus now supports multistream PeerConnections,\n * subscriptions can be done either in \"bulks\" (you use a single PeerConnection\n * to subscribe to multiple streams from one or more publishers) or\n * separately (each PeerConnections represents a subscription to a single\n * publisher). Same thing for publishers: you may choose to publish, e.g.,\n * audio and video on one PeerConnection, and share your screen on another,\n * or publish everything on the same PeerConnection instead. While\n * functionally both approaches (multistream vs. legacy mode) are the same\n * (the same media flows in both cases), the differences are in how\n * resources are used, and in how the client has to handle incoming and\n * outgoing connections. Besides, one approach might make more sense in\n * some scenarios, and the other make more sense in different use cases.\n * As such, the approach to follow is left to the developer and the application.\n *\n * What is important to point out, though, is that publishers and subscribers\n * will in all cases require different PeerConnections. This means that,\n * even with multistream, you won't be able to use a single PeerConnection\n * to send your contributions and receive those from everyone else. This\n * is a choice done by design, to avoid the issues that would inevitably\n * arise when doing, for instance, renegotiations to update the streams.\n *\n * On a more general note and to give some more context with respect to the\n * core functionality in Janus, notice that, considering this plugin allows\n * for several different WebRTC PeerConnections to be on at the same time\n * for the same peer (different publishers and subscribers for sure, and\n * potentially more than one of each if multistream is not in use), each\n * peer will often need to attach several times to the same plugin for each\n * stream: this means that each peer needs to have at least one handle active\n * for managing its relation with the plugin (joining a room,\n * leaving a room, muting/unmuting, publishing, receiving events), and needs\n * to open others when they want to subscribe to a feed from other participants\n * (the number depends on the subscription approach of choice). Handles\n * used for subscriptions, though, would be logically \"subjects\" to the\n * master one used for managing the room: this means that they cannot be\n * used, for instance, to unmute in the room, as their only purpose would\n * be to provide a context in which creating the recvonly PeerConnections\n * for the subscription(s).\n *\n * Rooms to make available are listed in the plugin configuration file.\n * A pre-filled configuration file is provided in \\c conf/janus.plugin.videoroom.jcfg\n * and includes a demo room for testing.

Anyway, this participation\n * allows the user to receive notifications about several aspects of the\n * room on the related handle (including streams as they become available\n * and go away). As such, it can be used even just as a way to get\n * notifications in a room, without the need of ever actually publishing\n * any stream at all (which explains why the \"publisher\" role may actually\n * be a bit confusing in this context).\n *\n * A successful \\c join will result in a \\c joined event, which will contain\n * a list of the currently active (as in publishing via WebRTC) publishers,\n * and optionally a list of passive attendees (but only if the room was\n * configured with \\c notify_joining set to \\c TRUE ):\n *\n\\verbatim\n{\n\t\"videoroom\" : \"joined\",\n\t\"room\" : <room ID>,\n\t\"description\" : <description of the room, if available>,\n\t\"id\" : <unique ID of the participant>,\n\t\"private_id\" : <a different unique ID associated to the participant; meant to be private>,\n\t\"publishers\" : [\n\t\t{\n\t\t\t\"id\" : <unique ID of active publisher #1>,\n\t\t\t\"display\" : \"<display name of active publisher #1, if any>\",\n\t\t\t\"metadata\" : <valid json object of metadata, if any>,\n\t\t\t\"dummy\" : <true if this participant is a dummy publisher>,\n\t\t\t\"streams\" : [\n\t\t\t\t{\n\t\t\t\t\t\"type\" : \"<type of published stream #1 (audio|video|data)\">,\n\t\t\t\t\t\"mindex\" : \"<unique mindex of published stream #1>\",\n\t\t\t\t\t\"mid\" : \"<unique mid of of published stream #1>\",\n\t\t\t\t\t\"disabled\" : <if true, it means this stream is currently inactive/disabled (and so codec, description, etc. will be missing)>,\n\t\t\t\t\t\"codec\" : \"<codec used for published stream #1>\",\n\t\t\t\t\t\"description\" : \"<text description of published stream #1, if any>\",\n\t\t\t\t\t\"moderated\" : <true if this stream audio has been moderated for this participant>,\n\t\t\t\t\t\"simulcast\" : \"<true if published stream #1 uses simulcast>\",\n\t\t\t\t\t\"svc\" : \"<true if published stream #1 uses SVC (VP9 and AV1 only)>\",\n\t\t\t\t\t\"talking\" : <true|false, whether the publisher stream has audio activity or not (only if audio levels are used)>,\n\t\t\t\t},\n\t\t\t\t// Other streams, if any\n\t\t\t],\n\t\t\t\"talking\" : <true|false, whether the publisher is talking or not (only if audio levels are used); deprecated, use the stream specific ones>,\n\t\t},\n\t\t// Other active publishers\n\t],\n\t\"attendees\" : [\t\t// Only present when notify_joining is set to TRUE for rooms\n\t\t{\n\t\t\t\"id\" : <unique ID of attendee #1>,\n\t\t\t\"display\" : \"<display name of attendee #1, if any>\",\n\t\t\t\"metadata\" : <valid json object of metadata, if any>\n\t\t},\n\t\t// Other attendees\n\t]\n}\n\\endverbatim\n *\n * Notice that the publishers list will of course be empty if no one is\n * currently active in the room.

As soon\n * as the PeerConnection has been established, the publisher will become\n * active, and a new active feed other participants can subscribe to.\n *\n * The syntax of a \\c publish request is the following:\n *\n\\verbatim\n{\n\t\"request\" : \"publish\",\n\t\"audiocodec\" : \"<audio codec to prefer among the negotiated ones; optional>\",\n\t\"videocodec\" : \"<video codec to prefer among the negotiated ones; optional>\",\n\t\"bitrate\" : <bitrate cap to return via REMB; optional, overrides the global room value if present>,\n\t\"record\" : <true|false, whether this publisher should be recorded or not; optional>,\n\t\"filename\" : \"<if recording, the base path/file to use for the recording files; optional>\",\n\t\"display\" : \"<display name to use in the room; optional>\",\n\t\"metadata\" : <valid json object of metadata; optional>,\n\t\"audio_level_average\" : \"<if provided, overrides the room audio_level_average for this user; optional>\",\n\t\"audio_active_packets\" : \"<if provided, overrides the room audio_active_packets for this user; optional>\",\n\t\"descriptions\" : [\t// Optional\n\t\t{\n\t\t\t\"mid\" : \"<unique mid of a stream being published>\",\n\t\t\t\"description\" : \"<text description of the stream (e.g., My front webcam)>\"\n\t\t},\n\t\t// Other descriptions, if any\n\t]}\n\\endverbatim\n *\n * As anticipated, since this is supposed to be accompanied by a JSEP SDP\n * offer describing the publisher's media streams, the plugin will negotiate\n * and prepare a matching JSEP SDP answer. Notice that, in principle, all\n * published streams will be only identified by their unique \\c mid and\n * by their type (e.g., audio or video). In case you want to provide more\n * information about the streams being published (e.g., to let other\n * participants know that the first video is a camera, while the second\n * video is a screen share), you can use the \\c descriptions array for\n * the purpose: each object in the array can be used to add a text description\n * to associate to a specific mid, in order to help with the UI rendering.\n * The \\c descriptions property is optional, so no text will be provided\n * by default: notice these descriptions can be updated dynamically via\n * \\c configure requests.\n *\n * If successful, a \\c configured event will be sent back, formatted like this:\n *\n\\verbatim\n{\n\t\"videoroom\" : \"event\",\n\t\"configured\" : \"ok\"\n}\n\\endverbatim\n *\n * This event will be accompanied by the prepared JSEP SDP answer.\n *\n * Notice that you can also use \\c configure as a request instead of\n * \\c publish to start publishing. The two are functionally equivalent\n * for publishing, but from a semantic perspective \\c publish is the\n * right message to send when publishing. The \\c configure request, as\n * it will be clearer later, can also be used to update some properties\n * of the publisher session: in this case the \\c publish request can NOT\n * be used, as it can only be invoked to publish, and will fail if you're\n * already publishing something.\n *\n * As an additional note, notice that you can also join and publish in\n * a single request, which is useful in case you're not interested in\n * first join as a passive attendee and only later publish something,\n * but want to publish something right away. In this case you can use\n * the \\c joinandconfigure request, which as you can imagine combines\n * the properties of both \\c join and \\c publish in a single request:\n * the response to a \\c joinandconfigure will be a \\c joined event, and\n * will again be accompanied by a JSEP SDP answer as usual.\n *\n * However you decided to publish something, as soon as the PeerConnection\n * setup succeeds and the publisher becomes active, an event is sent to\n * all the participants in the room with information on the new feed.\n * The event must contain an array with a single element, and be formatted like this:\n *\n\\verbatim\n{\n\t\"videoroom\" : \"event\",\n\t\"room\" : <room ID>,\n\t\"publishers\" : [\n\t\t{\n\t\t\t\"id\" : <unique ID of the new publisher>,\n\t\t\t\"display\" : \"<display name of the new publisher, if any>\",\n\t\t\t\"metadata\" : <valid json object of metadata, if any>,\n\t\t\t\"dummy\" : <true if this participant is a dummy publisher>,\n\t\t\t\"streams\" : [\n\t\t\t\t{\n\t\t\t\t\t\"type\" : \"<type of published stream #1 (audio|video|data)\">,\n\t\t\t\t\t\"mindex\" : \"<unique mindex of published stream #1>\",\n\t\t\t\t\t\"mid\" : \"<unique mid of of published stream #1>\",\n\t\t\t\t\t\"disabled\" : <if true, it means this stream is currently inactive/disabled (and so codec, description, etc. will be missing)>,\n\t\t\t\t\t\"codec\" : \"<codec used for published stream #1>\",\n\t\t\t\t\t\"description\" : \"<text description of published stream #1, if any>\",\n\t\t\t\t\t\"moderated\" : <true if this stream audio has been moderated for this participant>,\n\t\t\t\t\t\"simulcast\" : \"<true if published stream #1 uses simulcast>\",\n\t\t\t\t\t\"svc\" : \"<true if published stream #1 uses SVC (VP9 and AV1 only)>\",\n\t\t\t\t\t\"talking\" : <true|false, whether the publisher stream has audio activity or not (only if audio levels are used)>,\n\t\t\t\t},\n\t\t\t\t// Other streams, if any\n\t\t\t],\n\t\t\t\"talking\" : <true|false, whether the publisher is talking or not (only if audio levels are used); deprecated, use the stream specific ones>,\n\t\t}\n\t]\n}\n\\endverbatim\n *\n * To stop publishing and tear down the related PeerConnection, you can\n * use the \\c unpublish request, which requires no arguments as the context\n * is implicit:\n *\n\\verbatim\n{\n\t\"request\" : \"unpublish\"\n}\n\\endverbatim\n *\n * This will have the plugin tear down the PeerConnection, and remove the\n * publisher from the list of active streams.

Notice that the\n * \\c configure request can also be used in renegotiations, to provide\n * an updated SDP with changes to the published media.

In fact, while the main purpose of this plugin is\n * getting media from WebRTC sources (publishers) and relaying it to\n * WebRTC destinations (subscribers), there are actually several use\n * cases and scenarios for making this media available to external,\n * notnecessarily WebRTC-compliant, components. These components may\n * benefit from having access to the RTP media sent by a publisher, e.g.,\n * for media processing, external recording, transcoding to other\n * technologies via other applications, scalability purposes or\n * whatever else makes sense in this context. This is made possible by\n * a request called \\c rtp_forward which, as the name suggests, simply\n * forwards in real-time the media sent by a publisher via RTP (plain\n * or encrypted) to a remote backend. Notice that, although we're using\n * the term \"RTP forwarder\", this feature can be used to forward data\n * channel messages as well.\n *\n * You can add a new RTP forwarder for an existing publisher using the\n * \\c rtp_forward request, which has to be formatted as follows:\n *\n\\verbatim\n{\n\t\"request\" : \"rtp_forward\",\n\t\"room\" : <unique numeric ID of the room the publisher is in>,\n\t\"publisher_id\" : <unique numeric ID of the publisher to relay externally>,\n\t\"host\" : \"<host address to forward the RTP and data packets to>\",\n\t\"host_family\" : \"<ipv4|ipv6, if we need to resolve the host address to an IP; by default, whatever we get>\",\n\t\"streams\" : [\n\t\t{\n\t\t\t\"mid\" : \"<mid of publisher stream to forward>\",\n\t\t\t\"host\" : \"<host address to forward the packets to; optional, will use global one if missing>\",\n\t\t\t\"host_family\" : \"<optional, will use global one if missing>\",\n\t\t\t\"port\" : <port to forward the packets to>,\n\t\t\t\"ssrc\" : <SSRC to use to use when forwarding; optional, and only for RTP streams, not data>,\n\t\t\t\"pt\" : <payload type to use when forwarding; optional, and only for RTP streams, not data>,\n\t\t\t\"rtcp_port\" : <port to contact to receive RTCP feedback from the recipient; optional, and only for RTP streams, not data>,\n\t\t\t\"simulcast\" : <true|false, set to true if the source is simulcast and you want the forwarder to act as a regular viewer (single stream being forwarded) or false otherwise (substreams forwarded separately); optional, default=false>,\n\t\t\t\"port_2\" : <if video and simulcasting, port to forward the packets from the second substream/layer to>,\n\t\t\t\"ssrc_2\" : <if video and simulcasting, SSRC to use to use the second substream/layer; optional>,\n\t\t\t\"pt_2\" : <if video and simulcasting, payload type to use the second substream/layer; optional>,\n\t\t\t\"port_3\" : <if video and simulcasting, port to forward the packets from the third substream/layer to>,\n\t\t\t\"ssrc_3\" : <if video and simulcasting, SSRC to use to use the third substream/layer; optional>,\n\t\t\t\"pt_3\" : <if video and simulcasting, payload type to use the third substream/layer; optional>,\n\t\t},\n\t\t{\n\t\t\t.. other streams, if needed..\n\t\t}\n\t],\n\t\"srtp_suite\" : <length of authentication tag (32 or 80); optional>,\n\t\"srtp_crypto\" : \"<key to use as crypto (base64 encoded key as in SDES); optional>\"\n}\n\\endverbatim\n *\n * As you can see, you basically configure each stream to forward in a\n * dedicated object of the \\c streams array: for RTP streams (audio, video)\n * this includes optionally overriding payload type or SSRC; simulcast\n * streams can be forwarded separately for each layer. The only parameters\n * you MUST specify are the host and port to send the packets to: the host\n * part can be put in the global part of the request, if all streams will\n * be sent to the same IP address, while the port must be specific to the\n * stream itself.\n *\n * Notice that, as explained above, in case you configured an \\c admin_key\n * property and extended it to RTP forwarding as well, you'll need to provide\n * it in the request as well or it will be rejected as unauthorized. By\n * default no limitation is posed on \\c rtp_forward .\n *\n * It's worth spending some more words on how to forward simulcast publishers,\n * as this can lead to some confusion. There are basically two ways to forward\n * a simulcast publisher:\n *\n * -# you treat the forwarder as a regular viewer, which means you still only\n * forward a single stream to the recipient, that is the highest quality\n * available at any given time: you can do that by setting\n * <code>simulcast: true</code> in the \\c rtp_forward request;\n * -# you forward each substream separately instead, to different target\n * ports: you do that by specifying \\c video_port_2 , \\c video_port_3 and\n * optionally the other related \\c _2 and \\c _3 properties; this is what\n * you should use when you want to forward to a simulcast-aware Streaming\n * mountpoint (see the \\ref streaming for more details).\n *\n * The two approaches are mutually exclusive: you can NOT use them together\n * in the same RTP forwarder.\n *\n * A successful request will result in an \\c rtp_forward response, containing\n * the relevant info associated to the new forwarder(s):\n *\n\\verbatim\n{\n\t\"videoroom\" : \"rtp_forward\",\n\t\"room\" : <unique numeric ID, same as request>,\n\t\"publisher_id\" : <unique numeric ID, same as request>,\n\t\"forwarders\" : [\n\t\t{\n\t\t\t\"stream_id\" : <unique numeric ID assigned to this forwarder, if any>,\n\t\t\t\"type\" : \"<audio|video|data>\",\n\t\t\t\"host\" : \"<host this forwarder is streaming to, same as request if not resolved>\",\n\t\t\t\"port\" : <port this forwarder is streaming to, same as request if configured>,\n\t\t\t\"local_rtcp_port\" : <local port this forwarder is using to get RTCP feedback, if any>,\n\t\t\t\"remote_rtcp_port\" : <remote port this forwarder is getting RTCP feedback from, if any>,\n\t\t\t\"ssrc\" : <SSRC this forwarder is using, same as request if configured>,\n\t\t\t\"pt\" : <payload type this forwarder is using, same as request if configured>,\n\t\t\t\"substream\" : <video substream this video forwarder is relaying, if any>,\n\t\t\t\"srtp\" : <true|false, whether the RTP stream is encrypted (not used for data)>\n\t\t},\n\t\t// Other forwarders, if configured\n\t]\n}\n\\endverbatim\n *\n * To stop a previously created RTP forwarder and stop it, you can use\n * the \\c stop_rtp_forward request, which has to be formatted as follows:\n *\n\\verbatim\n{\n\t\"request\" : \"stop_rtp_forward\",\n\t\"room\" : <unique numeric ID of the room the publisher is in>,\n\t\"publisher_id\" : <unique numeric ID of the publisher to update>,\n\t\"stream_id\" : <unique numeric ID of the RTP forwarder>\n}\n\\endverbatim\n *\n * A successful request will result in a \\c stop_rtp_forward response:\n *\n\\verbatim\n{\n\t\"videoroom\" : \"stop_rtp_forward\",\n\t\"room\" : <unique numeric ID, same as request>,\n\t\"publisher_id\" : <unique numeric ID, same as request>,\n\t\"stream_id\" : <unique numeric ID, same as request>\n}\n\\endverbatim\n *\n * To get a list of all the forwarders in a specific room, instead, you\n * can make use of the \\c listforwarders request, which has to be\n * formatted as follows:\n *\n\\verbatim\n{\n\t\"request\" : \"listforwarders\",\n\t\"room\" : <unique numeric ID of the room>,\n\t\"secret\" : \"<room secret;

If you were simply lurking and not\n * publishing, the other participants will only receive the \"leaving\" event.\n *\n * \\subsection vroomsub VideoRoom Subscribers\n *\n * In a VideoRoom, subscribers are NOT participants, but simply handles\n * that will be used exclusively to receive media from one or more publishers\n * in the room. Since they're not participants per se, they're basically\n * streams that can be (and typically are) associated to publisher handles\n * as the ones we introduced in the previous section, whether active or not.\n * In fact, the typical use case is publishers being notified about new\n * participants becoming active in the room, and as a result new subscriber\n * sessions being created to receive their media streams; as soon as the\n * publisher goes away, other participants are notified so that the related\n * subscriber handles can be removed/updated accordingly as well. As such,\n * these subscriber sessions are dependent on feedback obtained by\n * publishers, and can't exist on their own, unless you feed them the\n * right info out of band (which is impossible in rooms configured with\n * \\c require_pvtid).\n *\n * To specify that a handle will be associated with a subscriber, you must use\n * the \\c join request with \\c ptype set to \\c subscriber and specify which\n * feed to subscribe to. The exact syntax of the request is the following:\n *\n\\verbatim\n{\n\t\"request\" : \"join\",\n\t\"ptype\" : \"subscriber\",\n\t\"room\" : <unique ID of the room to subscribe in>,\n\t\"use_msid\" : <whether subscriptions should include an msid that references the publisher; false by default>,\n\t\"autoupdate\" : <whether a new SDP offer is sent automatically when a subscribed publisher leaves; true by default>,\n\t\"private_id\" : <unique ID of the publisher that originated this request; optional, unless mandated by the room configuration>,\n\t\"streams\" : [\n\t\t{\n\t\t\t\"feed\" : <unique ID of publisher owning the stream to subscribe to>,\n\t\t\t\"mid\" : \"<unique mid of the publisher stream to subscribe to; optional>\"\n\t\t\t\"crossrefid\" : \"<id to map this subscription with entries in streams list; optional>\"\n\t\t\t// Optionally, simulcast or SVC targets (defaults if missing)\n\t\t},\n\t\t// Other streams to subscribe to\n\t]\n}\n\\endverbatim\n *\n * As you can see, it's just a matter of specifying the list of streams to\n * subscribe to: in particular, you have to provide an array of objects,\n * where each objects represents a specific stream (or group of streams)\n * you're interested in. For each object, the \\c feed_id indicating the\n * publisher owning the stream(s) is mandatory, while the related \\c mid\n * is optional: this gives you some flexibility when subscribing, as\n * only providing a \\c feed_id will indicate you're interested in ALL\n * the stream from that publisher, while providing a \\c mid as well will\n * indicate you're interested in a stream in particular. Since you can\n * provide an array of streams, just specifying the \\c feed_id or explicitly\n * listing all the \\c feed_id + \\c mid combinations is equivalent: of\n * course, different objects in the array can indicate different publishers,\n * allowing you to combine streams from different sources in the same subscription.\n * Notice that if a publisher stream is marked as \\c disabled and you try\n * to subscribe to it, it will be skipped silently.\n *\n * Depending on whether the subscription will refer to a\n * single publisher (legacy approach) or to streams coming from different\n * publishers (multistream), the list of streams may differ. The ability\n * to single out the streams to subscribe to is particularly useful in\n * case you don't want to, or can't, subscribe to all available media:\n * e.g., you know a publisher is sending both audio and video, but video\n * is in a codec you don't support or you don't have bandwidth for both;\n * or maybe there are 10 participants in the room, but you only want video\n * from the 3 most active speakers; and so on.

As soon as that happens, the VideoRoom plugin\n * can start relaying media the recipient subscribed to.\n *\n * Once a WebRTC PeerConnection has been established for a subscriber, in\n * case you want to update a subscription you have to use the \\c subscribe ,\n * \\c unsubscribe or \\c update methods: as the names of the requests suggest, the\n * former allows you to add more streams to subscribe to, the second\n * instructs the plugin to remove streams you're currently subscribe to,\n * while the latter allows you to perform both operations at the same time.\n * Any of those requests will trigger a renegotiation, if they were successful,\n * meaning the plugin will send you a new JSEP offer you'll have to reply\n * to with an answer: to send the answer, just use the same \\c start request\n * we already described above. Notice that renegotiations may not be\n * triggered right away, e.g., whenever you're trying to update a session\n * and the plugin is still in the process of renegoting a previous update\n * for the same subscription: in that case, an update will be scheduled\n * and a renegotiation will be triggered as soon as it's viable, and an\n * empty \\c updating event will be triggered instead to notify the caller\n * that the management of that request has been postponed. It's also\n * important to point out that the number of offers generated in response\n * to those requests may not match the amount of requests: in fact, since\n * requests are postponed, a single offer may be sent in response to\n * multiple requests to update a subscription at the same time, thus\n * addressing them all in a cumulative way. This means clients should\n * never expect an offer any time they request one.\n *\n * The syntax of the \\c subscribe mirrors the one for new subscriptions,\n * meaning you use the same \\c streams array to address the new streams\n * you want to receive, and formatted the same way:\n *\n\\verbatim\n{\n\t\"request\" : \"subscribe\",\n\t\"streams\" : [\n\t\t{\n\t\t\t\"feed\" : <unique ID of publisher owning the new stream to subscribe to>,\n\t\t\t\"mid\" : \"<unique mid of the publisher stream to subscribe to; optional>\"\n\t\t\t\"crossrefid\" : \"<id to map this subscription with entries in streams list; optional>\"\n\t\t\t// Optionally, send, simulcast or SVC targets (defaults if missing)\n\t\t},\n\t\t// Other new streams to subscribe to\n\t]\n}\n\\endverbatim\n *\n * This means the exact same considerations we made on \\c streams before\n * apply here as well: whatever they represent, will indicate the willingness\n * to subscribe to the related stream. Notice that if you were already\n * subscribed to one of the new streams indicated here, you'll subscribe\n * to it again in a different m-line, so it's up to you to ensure you\n * avoid duplicates (unless that's what you wanted, e.g., for testing\n * purposes). In case the update was successful, you'll get an \\c updated\n * event, containing the updated layout of all subscriptions (pre-existing\n * and new ones), and a new JSEP offer to renegotiate the session:\n *\n\\verbatim\n{\n\t\"videoroom\" : \"updated\",\n\t\"room\" : <room ID>,\n\t\"streams\": [\n\t\t{\n\t\t\t\"mindex\" : <unique m-index of this stream>,\n\t\t\t\"mid\" : \"<unique mid of this stream>\",\n\t\t\t\"type\" : \"<type of this stream's media (audio|video|data)>\",\n\t\t\t\"feed_id\" : <unique ID of the publisher originating this stream>,\n\t\t\t\"feed_mid\" : \"<unique mid of this publisher's stream>\",\n\t\t\t\"feed_display\" : \"<display name of this publisher, if any>\",\n\t\t\t\"send\" : <true|false; whether we configured the stream to relay media>,\n\t\t\t\"ready\" : <true|false; whether this stream is ready to start sending media (will be false at the beginning)>\n\t\t},\n\t\t// Other streams in the subscription, if any; old and new\n\t]\n}\n\\endverbatim\n *\n * Notice that if your \\c subscribe request didn't change anything as far\n * as the SDP negotiation is concerned (e.g., subscribing to new data streams\n * where a datachannel existed already), you'll simply get an \\c updated\n * event back with no \\c streams object.\n *\n * As explained before, in case the message contains a JSEP offer (which may\n * not be the case if no change occurred), then clients will need to send\n * a new JSEP answer with a \\c start request to close this renegotiation.\n *\n * The \\c unsubscribe request works pretty much the same way, with the\n * difference that the \\c streams array you provide to specify what to\n * unsubscribe from may look different. Specifically, the syntax looks\n * like this:\n *\n\\verbatim\n{\n\t\"request\" : \"unsubscribe\",\n\t\"streams\" : [\n\t\t{\n\t\t\t\"feed\" : <unique ID of publisher owning the new stream to unsubscribe from; optional>,\n\t\t\t\"mid\" : \"<unique mid of the publisher stream to unsubscribe from; optional>\"\n\t\t\t\"sub_mid\" : \"<unique mid of the subscriber stream to unsubscribe; optional>\"\n\t\t},\n\t\t// Other streams to unsubscribe from\n\t]\n}\n\\endverbatim\n *\n * This means that you have different ways to specify what to unsubscribe from:\n * if an object only specifies \\c feed_id, then all the subscription streams that\n * were receiving media from that publisher will be removed; if an object\n * specifies \\c feed_id and \\c mid, then all the subscription streams that\n * were receiving media from the publisher stream with the related mid will be\n * removed; finally, if an object only specifies \\c sub_mid instead, then\n * only the stream in the subscription that is addressed by the related mid\n * (subscription mid, no relation to the publishers') will be removed. As\n * such, you have a great deal of flexibility in how to unsubscribe from\n * media. Notice that multiple streams may be removed in case you refer\n * to the \"source\" ( \\c feed_id ), rather than the \"sink\" ( \\c sub_mid ),\n * especially in case the subscription contained duplicates or multiple\n * streams from the same publisher.\n *\n * A successful \\c unsubscribe will result in exactly the same \\c updated\n * event \\c subscribe triggers, so the same considerations apply with\n * respect to the potential need of a renegotiation and how to complete\n * it with a \\c start along a JSEP answer. Again, if \\c unsubscribe didn't\n * result in SDP changes (e.g., unsubscribing from a data channel stream),\n * you'll simply get an \\c updated event back with no \\c streams object.\n *\n * As anticipated, the \\c update request allows you to combine changes\n * to a subscription where you may want to both subscribe to new streams,\n * and unsubscribe from existing ones, which the existing \\c subscribe\n * and \\c unsubscribe requests wouldn't allow you to do as they work\n * exclusively on the action specified by their name. The syntax for\n * the \\c update request is very similar to the previous method, meaning\n * arrays are still used to address the streams to work on, with the key\n * difference that they won't be named \\c streams, but \\c subscribe and\n * \\c unsubscribe instead:\n *\n\\verbatim\n{\n\t\"request\" : \"update\",\n\t\"subscribe\" : [\n\t\t{\n\t\t\t\"feed\" : <unique ID of publisher owning the new stream to subscribe to>,\n\t\t\t\"mid\" : \"<unique mid of the publisher stream to subscribe to; optional>\"\n\t\t\t\"crossrefid\" : \"<id to map this subscription with entries in streams list; optional>\"\n\t\t\t// Optionally, send, simulcast or SVC targets (defaults if missing)\n\t\t},\n\t\t// Other new streams to subscribe to\n\t],\n\t\"unsubscribe\" : [\n\t\t{\n\t\t\t\"feed\" : <unique ID of publisher owning the new stream to unsubscribe from; optional>,\n\t\t\t\"mid\" : \"<unique mid of the publisher stream to unsubscribe from; optional>\"\n\t\t\t\"sub_mid\" : \"<unique mid of the subscriber stream to unsubscribe; optional>\"\n\t\t},\n\t\t// Other streams to unsubscribe from\n\t]\n}\n\\endverbatim\n *\n * Both the \\c subscribe and \\c unsubscribe arrays are optional, which means\n * that an \\c update request to only subscribe to new streams will be\n * functionally equivalent to a \\c subscribe request, and an \\c update\n * request to only unsubscribe will be functionally equivalent to an\n * \\c unsubscribe request instead. That said, one of the two must be\n * provided, which means that an \\c update request that doesn't include\n * either of them will result in an error.\n *\n * A successful \\c update will result in exactly the same \\c updated event\n * \\c subscribe and \\c unsubscribe trigger, so the same considerations apply\n * with respect to the potential need of a renegotiation and how to complete\n * it with a \\c start along a JSEP answer. Again, if \\c update didn't\n * result in SDP changes, you'll simply get an \\c updated event back with\n * no \\c streams object.\n *\n * Notice that, in case you want to trigger an ICE restart rather than\n * updating a subscription, you'll have to use a different request, named\n * \\c configure: this will be explained in a few paragraphs.\n *\n * As a subscriber, you can temporarily pause and resume the whole media delivery\n * with a \\c pause and, again, \\c start request (in this case without any JSEP\n * SDP answer attached). Neither expect other arguments, as the context\n * is implicitly derived from the handle they're sent on:\n *\n\\verbatim\n{\n\t\"request\" : \"pause\"\n}\n\\endverbatim\n *\n\\verbatim\n{\n\t\"request\" : \"start\"\n}\n\\endverbatim\n *\n * Unsurprisingly, they just result in, respectively, \\c paused and\n * \\c started events:\n *\n\\verbatim\n{\n\t\"videoroom\" : \"event\",\n\t\"paused\" : \"ok\"\n}\n\\endverbatim\n *\n\\verbatim\n{\n\t\"videoroom\" : \"event\",\n\t\"started\" : \"ok\"\n}\n\\endverbatim\n *\n * For more drill-down manipulations of a subscription, a \\c configure\n * request can be used instead. This request allows subscribers to dynamically\n * change some properties associated to their media subscription, e.g.,\n * in terms of what should and should not be sent at a specific time. A\n * \\c configure request must be formatted as follows:\n *\n\\verbatim\n{\n\t\"request\" : \"configure\",\n\t\"streams\" : [\n\t\t{\n\t\t\t\"mid\" : <mid of the m-line to refer to>,\n\t\t\t\"send\" : <true|false, depending on whether the mindex media should be relayed or not; optional>,\n\t\t\t\"substream\" : <substream to receive (0-2), in case simulcasting is enabled; optional>,\n\t\t\t\"temporal\" : <temporal layers to receive (0-2), in case simulcasting is enabled; optional>,\n\t\t\t\"fallback\" : <How much time (in us, default 250000) without receiving packets will make us drop to the substream below; optional>,\n\t\t\t\"spatial_layer\" : <spatial layer to receive (0-2), in case SVC is enabled; optional>,\n\t\t\t\"temporal_layer\" : <temporal layers to receive (0-2), in case SVC is enabled; optional>,\n\t\t\t\"audio_level_average\" : \"<if provided, overrides the room audio_level_average for this user; optional>\",\n\t\t\t\"audio_active_packets\" : \"<if provided, overrides the room audio_active_packets for this user; optional>\",\n\t\t\t\"min_delay\" : <minimum delay to enforce via the playout-delay RTP extension, in blocks of 10ms; optional>,\n\t\t\t\"max_delay\" : <maximum delay to enforce via the playout-delay RTP extension, in blocks of 10ms; optional>,\n\t\t},\n\t\t// Other streams, if any\n\t],\n\t\"restart\" : <trigger an ICE restart; optional>\n}\n\\endverbatim\n *\n * As you can see, the \\c mid and \\c send properties can be used as a media-level\n * pause/resume functionality (\"only mute/unmute this mid\"), whereas \\c pause\n * and \\c start simply pause and resume all streams at the same time.\n * The \\c substream and \\c temporal properties, instead, only make sense\n * when the publisher is configured with video simulcasting support, and\n * as such the subscriber is interested in receiving a specific substream\n * or temporal layer, rather than any other of the available ones: notice\n * that for them to work you'll have to specify the \\c mid as well, as the same\n * subscription may be receiving simulcast stream from multiple publishers.\n * The \\c spatial_layer and \\c temporal_layer have exactly the same meaning,\n * but within the context of SVC publishers, and will have no effect\n * on subscriptions associated to regular publishers.\n *\n * As anticipated, \\c configure is also the request you use when you want\n * to trigger an ICE restart for a subscriber: in fact, while publishers\n * can force a restart themselves by providing the right JSEP offer, subscribers\n * always receive an offer from Janus instead, and as such have to\n * explicitly ask for a dedicated offer when an ICE restart is needed;\n * in that case, just set \\c restart to \\c true in a \\c configure request,\n * and a new JSEP offer with ICE restart information will be sent to the\n * client, to which the client will have to reply, as usual, via \\c start\n * along a JSEP answer. This documentation doesn't explain when or why\n * an ICE restart is needed or appropriate: please refer to the ICE RFC\n * or other sources of information for that.\n *\n * Another interesting feature that subscribers can take advantage of is the\n * so-called publisher \"switching\". Basically, when subscribed to one or more\n * publishers and receiving media from them, you can at any time \"switch\"\n * any of the subscription streams to a different publisher, and as such\n * start receiving media on the related m-line from that publisher instead,\n * all without doing a new \\c subscribe or \\c unsubscribe, and so without\n * the need of doing any renegotiation at all; just some logic changes.\n * Think of it as changing channel on a TV: you keep on using the same\n * PeerConnection, the plugin simply changes the source of the media\n * transparently. Of course, while powerful and effective this request has\n * some limitations: in fact, the source (audio or video) that you switch\n * to must have the same media configuration (e.g., same codec) as the source\n * you're replacing. In fact, since the same PeerConnection is used for this\n * feature and no renegotiation is taking place, switching to a stream with\n * a different configuration would result in media incompatible with the\n * PeerConnection setup being relayed to the subscriber (e.g., negotiated\n * VP9, but new source is H.264), and as such in no audio/video being played;\n * in that case, you'll need a \\c subscribe instead, and a new m-line.\n *\n * That said, a \\c switch request must be formatted like this:\n *\n\\verbatim\n{\n\t\"request\" : \"switch\",\n\t\"streams\" : [\n\t\t{\n\t\t\t\"feed\" : <unique ID of the publisher the new source is from>,\n\t\t\t\"mid\" : \"<unique mid of the source we want to switch to>\",\n\t\t\t\"sub_mid\" : \"<unique mid of the stream we want to pipe the new source to>\"\n\t\t\t.. other properties, e.g., substream, temporal, etc.\n\t\t},\n\t\t{\n\t\t\t// Other updates, if any\n\t\t}\n\t]\n}\n\\endverbatim\n *\n * While apparently convoluted, this is actually a quite effective and powerful\n * way of updating subscriptions without renegotiating. In fact, it allows for\n * full or partial switches: for instance, sometimes you may want to replace all\n * audio and video streams (e.g., switching from Bob to Alice in a \"legacy\"\n * VideoRoom usage, where each PeerConnection subscription is a different\n * publisher), or just replace a subset of them (e.g., you have a subscription\n * with three video slots, and you change one of them depending on the loudest\n * speaker). What to replace is dictated by the \\c streams array, where each\n * object in the array contains all the info needed for the switch to take\n * place: in particular, you must specify which of your subscription m-lines\n * you're going to update, via \\c sub_mid , and which publisher stream should\n * now start to feed it via \\c feed and \\c mid.\n *\n * If successful, the specified subscriptions will be updated, meaning they'll\n * be unsubscribed from the previous publisher stream, and subscribed to the\n * new publisher stream instead, all without a renegotiation (so no new SDP\n * offer/answer exchange to take care of). The event to confirm the switch\n * was successful will look like this:\n *\n\\verbatim\n{\n\t\"videoroom\" : \"event\",\n\t\"switched\" : \"ok\",\n\t\"room\" : <room ID>,\n\t\"changes\" : <number of successful changes (may be smaller than the size of the streams array provided in the request)>,\n\t\"streams\" : [\n\t\t// Current configuration of the subscription, same format as when subscribing\n\t\t// Will contain info on all streams, not only those that have been updated\n\t]\n}\n\\endverbatim\n *\n * Notice that, while a \\c switch request usually doesn't require a renegotiation,\n * it \\b MIGHT trigger one nevertheless: in fact, if a \"switch\" request assigns\n * a new publisher stream to a previously inactive subscriber stream, then\n * a renegotiation to re-activate that stream will be needed as well, as\n * otherwise the packets from the new source will not be relayed.\n *\n * Finally, to close a subscription and tear down the related PeerConnection,\n * you can use the \\c leave request. Since context is implicit, no other\n * argument is required:\n *\n\\verbatim\n{\n\t\"request\" : \"leave\"\n}\n\\endverbatim\n *\n * If successful, the plugin will attempt to tear down the PeerConnection,\n * and will send back a \\c left event:\n *\n\\verbatim\n{\n\t\"videoroom\" : \"event\",\n\t\"left\" : \"ok\",\n}\n\\endverbatim\n *\n * \\subsection vroomcasc Remote publishers (room cascading)\n *\n * Normally, the VideoRoom plugin can only route streams associated to\n * users connected to the Janus instance the plugin lives in: this means\n * that, within the context of a room, you can only subscribe to publishers\n * connected to the same server (and room) you're on.\n *\n * That said, there are obviously ways to address this constraint. In\n * the past, a typical approach for handling this (e.g., for scalability\n * or geo-distribution purposes) was to use the \\c rtp_forward request\n * to feed one or more local/remote Streaming plugin mountpoints, so that\n * a VideoRoom publisher could be consumed using the Streaming plugin\n * instead, possibly on a completely different Janus instance. This works\n * and has been used extensively (by ourselves too), but has the downside\n * that this completely excludes the VideoRoom API in terms of presence\n * and subscriptions: it's up to you, for instance, to advertise these\n * redistributed streams somehow, and associate them to the original\n * publisher from a semantics perspective.\n *\n * That said, the VideoRoom plugin now also has a concept of remote\n * publishers, that allows you to remotize local VideoRoom publishers\n * to different VideoRoom instances, which can in turn advertise the\n * presence of these remote subscribers along with their local publishers.\n * This allows subscribers to use the VideoRoom API, transparently, to\n * subscribe to both local and remote publishers seamlessly, knowing\n * that the involved VideoRoom instances will exchange the media packets\n * among them to make it happen.\n *\n * It's important to point out that this is not something that's completely\n * automated: it's still up to you, via API calls, to instruct all involved\n * VideoRoom instances, so that the remotization can happen, and to keep\n * it up do that (e.g., after renegotiations occur).\n *\n * Specifically, the VideoRoom API exposes the \\c add_remote_publisher ,\n * \\c update_remote_publisher , \\c remove_remote_publisher ,\n * \\c publish_remotely , \\c unpublish_remotely and \\c list_remotes\n * requests.\n *\n * Assuming that \\b Janus \\b A wants to make one of its local publishers available\n * in a room on \\b Janus \\b B as well, this is the process you must follow:\n *\n *   - you use \\c add_remote_publisher on \\b Janus \\b B (the target instance)\n * to add a new remote publisher; this will return some connectivity info\n * to the caller, and immediately advertise the new publisher to other\n * attendees in \\b Janus \\b B even before media actually arrives;\n *   - you use \\c publish_remotely on \\b Janus \\b A (the source instance),\n * using the info returned from the previous call; this has the result\n * of instructing \\b Janus \\b A to start relaying all RTP packets associated\n * to that publisher to \\b Janus \\b B ;\n *   - any time the publisher on \\b Janus \\b A renegotiates their session (e.g.,\n * a new audio or video stream is added, or removed), you should use\n * \\c update_remote_publisher on \\b Janus \\b B so that the remote instance\n * is aware of the changes, and can notify people in the room accordingly\n * (e.g., so that they can update their subscriptions accordingly);\n *   - when the publisher on \\b Janus \\b A leaves, an \\c unpublish_remotely\n * request must be sent on \\b Janus \\b A to ensure no media is forwarded anymore,\n * and at the same time a \\c remove_remote_publisher must be sent to\n * \\b Janus \\b B so that other attendees can be notified the participant\n * has left.\n *\n * Using these requests, the two Janus instances will transparently and\n * automatically communicate using internally created RTP forwarders. The\n * same ports are used for all RTP packets, so multiplexing is performed\n * using a simple math on SSRC identifiers: this means that there's no need\n * to open new ports as a consequence of renegotiations of a publisher,\n * but only to notify the recipient about what media is on its way, and\n * demultiplexing will be performed automatically.\n *\n * Everything else (subscribing to, and unsubscribing from, remote publishers)\n * works exactly the same way as shown in the previous sections. As far as\n * local attendees are concerned, a remote publisher is advertised and looks\n * exactly like any other local publisher. The details about how the\n * remotization works behind the scenes is hidden from them, and not\n * relevant to the subscription process.\n *\n * Coming to how the requests need to be formatted, the \\c add_remote_publisher\n * must be formatted like the following:\n *\n\\verbatim\n{\n\t\"request\" : \"add_remote_publisher\",\n\t\"room\" : <unique ID of the room to add the remote publisher to>,\n\t\"id\" : <unique ID to register for the remote publisher;

    "content": "/*! \\file   plugin.h\n * \\author Lorenzo Miniero <lorenzo@meetecho.com>\n * \\copyright GNU General Public License v3\n * \\brief  Plugin-Core communication\n * \\details  This header contains the definition of the callbacks both\n * the Janus core and all the plugins need to implement to interact with\n * each other. The structures to make the communication possible are\n * defined here as well.\n *\n * In particular, the Janus core implements the \\c janus_callbacks interface.\n * This means that, as a plugin, you can use the methods it exposes to\n * contact the core, e.g., in order to have it relay a message, event\n * or RTP/RTCP packet to the peer you're handling. In particular, the\n * methods the core exposes to plugins are:\n *\n * - \\c push_event(): to send a JSON message/event to the peer (with or without\n * an attached JSEP formatted SDP to negotiate a WebRTC PeerConnection);\n * the syntax of the message/event is completely up to you, the only\n * important thing is that it MUST be a JSON object, as it will be included\n * as such within the Janus session/handle protocol;\n * - \\c relay_rtp(): to send/relay the peer an RTP packet;\n * - \\c relay_rtcp(): to send/relay the peer an RTCP message.\n * - \\c relay_data(): to send/relay the peer a SCTP DataChannel message.\n *\n * On the other hand, a plugin that wants to register at the Janus core\n * needs to implement the \\c janus_plugin interface. Besides, as a\n * plugin is a shared object, and as such external to the core itself,\n * in order to be dynamically loaded at startup it needs to implement\n * the \\c create_p() hook as well, that should return a pointer to the\n * plugin instance. This is an example of such a step:\n *\n\\verbatim\nstatic janus_plugin myplugin = {\n\t[..]\n};\n\njanus_plugin *create(void) {\n\tJANUS_LOG(LOG_VERB, , \"%s created!\\n\", MY_PLUGIN_NAME);\n\treturn &myplugin;\n}\n\\endverbatim\n *\n * This will make sure that your plugin is loaded at startup by the Janus core,\n * if it is deployed in the proper folder.\n *\n * As anticipated and described in the above example, a plugin must basically\n * be an instance of the \\c janus_plugin type. As such, it must implement\n * the following methods and callbacks for the core:\n *\n * - \\c init(): this is called by the Janus core as soon as your plugin is started;\n * this is where you should setup your plugin (e.g., static stuff and reading\n * the configuration file);\n * - \\c destroy(): on the other hand, this is called by the core when it\n * is shutting down, and your plugin should too;\n * - \\c get_api_compatibility(): this method MUST return JANUS_PLUGIN_API_VERSION;\n * - \\c get_version(): this method should return a numeric version identifier (e.g., 3);\n * - \\c get_version_string(): this method should return a verbose version identifier (e.g., \"v1.0.1\");\n * - \\c get_description(): this method should return a verbose description of your plugin (e.g., \"This is my awesome plugin that does this and that\");\n * - \\c get_name(): this method should return a short display name for your plugin (e.g., \"My Awesome Plugin\");\n * - \\c get_package(): this method should return a unique package identifier for your plugin (e.g., \"janus.plugin.myplugin\");\n * - \\c create_session(): this method is called by the core to create a session between you and a peer;\n * - \\c handle_message(): a callback to notify you the peer sent you a message/request;\n * - \\c handle_admin_message(): a callback to notify you a message/request came from the Admin API;\n * - \\c setup_media(): a callback to notify you the peer PeerConnection is now ready to be used;\n * - \\c incoming_rtp(): a callback to notify you a peer has sent you a RTP packet;\n * - \\c incoming_rtcp(): a callback to notify you a peer has sent you a RTCP message;\n * - \\c incoming_data(): a callback to notify you a peer has sent you a message on a SCTP DataChannel;\n * - \\c data_ready(): a callback to notify you data can be sent on the SCTP DataChannel;\n * - \\c slow_link(): a callback to notify you Janus or the peer have lost packets recently, and the media path may be slow;\n * - \\c hangup_media(): a callback to notify you the peer PeerConnection has been closed (e.g., after a DTLS alert);\n * - \\c query_session(): this method is called by the core to get plugin-specific info on a session between you and a peer;\n * - \\c destroy_session(): this method is called by the core to destroy a session between you and a peer.\n *\n * All the above methods and callbacks, except for \\c incoming_rtp ,\n * \\c incoming_rtcp , \\c incoming_data and \\c slow_link , are mandatory:\n * the Janus core will reject a plugin that doesn't implement any of the\n * mandatory callbacks. The previously mentioned ones, instead, are\n * optional, so you're free to implement only those you care about. If\n * your plugin will not handle any data channel, for instance, it makes\n * sense to not implement the \\c incoming_data callback at all. At the\n * same time, if your plugin is ONLY going to use data channels and\n * can't care less about RTP or RTCP, \\c incoming_rtp and \\c incoming_rtcp\n * can be left out. Finally, \\c slow_link is just there as a helper, some\n * additional information you may be interested about, but you're not\n * forced to receive it if you don't care.\n *\n * The Janus core \\c janus_callbacks interface is provided to a plugin, together\n * with the path to the configurations files folder, in the \\c init() method.\n * This path can be used to read and parse a configuration file for the\n * plugin: the plugins we made available out of the box use the package\n * name as a name for the file (e.g., \\c janus.plugin.echotest.cfg for\n * the Echo Test plugin), but you're free to use a different one, as long\n * as it doesn't collide with existing ones. Besides, the existing plugins\n * use the same INI format for configuration files the core uses (relying\n * on the \\c janus_config helpers for the purpose) but again, if you prefer\n * a different format (XML, JSON, etc.) that's up to you.\n *\n * Both the Janus core and a plugin can have several different sessions\n * with the same and/or different peers: to match a specific session,\n * a plugin can rely on a mapping called janus_plugin_session that\n * is what all the communication between the plugins and the core\n * (that is, both methods invoked by the core and callbacks invoked by\n * the plugins) will make use of. See the janus_videoroom.c plugin for\n * an example of multiple handles associated to the same peer.\n *\n * All messages/requests/events sent to and received from a plugin are\n * asynchronous, meaning there's no way to immediately reply to a message\n * sent by a browser, for instance. Messages/requests coming from browsers\n * in a \\c handle_message() callback, though, have a transaction\n * identifier, which you can use in a \\c push_event() reply to allow the\n * browser to match it to the original request, if needed.\n *\n * As anticipated, both \\c handle_message() and \\c push_event() can attach\n * a JSEP/SDP payload. This means that a browser, for instance, can attach\n * a JSEP/SDP offer to negotiate a WebRTC PeerConnection with a plugin: the plugin\n * would then need to provide, immediately or not, a JSEP/SDP answer to\n * do so. At the same time, a plugin may want to originate the call instead:\n * in that case, the plugin would attach a JSEP/SDP offer in a \\c push_event()\n * call, to which the browser would then need to reply with a JSEP/SDP answer,\n * as described in \\ref JS. Renegotiating a session can be done using the\n * same mechanism above: in case plugins want to force an ICE restart,\n * though, they must add a boolean property called \\c restart to the JSEP\n * object before passing it to the core. Notice that the core adds a property\n * called \\c update whenever the remote user is requesting a renegotiation,\n * whether it's for ICE restarts or just for some media related change.\n * \\note It's important to notice that, while the Janus core would indeed\n * take care of the WebRTC PeerConnection setup itself in terms of\n * ICE/DTLS/RT(C)P on your behalf, plugins are what will actually manipulate\n * the media flowing around, and as such it's them who are responsible for\n * what concerns the codec negotiation in a JSEP/SDP offer/answer. This\n * normally is not something you need to worry about, especially if you're\n * just moving SDP around (e.g., janus_echotest.c or janus_videocall.c).\n * If your plugin is going to generate media frames (e.g., as janus_audiobridge.c),\n * you only support some codecs (e.g., Opus in janus_audiobridge.c) or you\n * want to use the same SDP offer for several different sessions (e.g., a webinar),\n * you need to make sure that your offer/answer does not contain anything\n * you don't support. Besides, you also need to make sure that you use\n * SDP-provided information (e.g., payload types, increasing versions in\n * case of renegotiations) coherently.\n *\n * \\todo Right now plugins can only interact with peers through the Janus core.\n * Besides, a single PeerConnection can at the moment be used by only one\n * plugin, as that plugin is actually the \"owner\" of the PeerConnection itself.\n *\n * \\ingroup pluginapi\n * \\ref pluginapi\n */\n\n#ifndef JANUS_PLUGIN_H\n#define JANUS_PLUGIN_H\n\n#include <stdlib.h>\n#include <stdint.h>\n#include <stdio.h>\n#include <string.h>\n#include <ctype.h>\n#include <unistd.h>\n#include <inttypes.h>\n\n#include <glib.h>\n\n#include \"../refcount.h\"\n\n\n/*! \\brief Version of the API, to match the one plugins were compiled against\n *\n * \\note This was added in version 0.0.7 of Janus, to address changes\n * to the API that might break existing plugin or the core itself.

When creating\n * a new packet, it should be initialized with janus_plugin_rtp_init. Besides\n * the data and its length, it also contains info on whether the packet is\n * audio or video, and a list of the parsed RTP extensions provided in\n * an instance of the janus_plugin_rtp_extensions structure. Notice that,\n * while this list of extensions is mostly a commodity when receiving a\n * packet, making it easier to access their values (the RTP extensions\n * will still be part of the incoming RTP packet, so plugins are still free\n * to parse them manually), they're very important when it comes to\n * outgoing packets instead: in fact, since the Janus core may needs to\n * terminate its own extensions with the peer, all RTP extensions that\n * are in an RTP packet sent by a plugin are stripped when relay_rtp is\n * called. This means that any attempt to inject an RTP extension in an\n * outgoing packet will fail if the RTP extension is added to the payload\n * manually, and will need to be set in the janus_plugin_rtp_extensions\n * structure instead. It's also important to initialize the extensions\n * structure before passing the packet to the core, as for each extension\n * there may be a different way of telling the core whether the extension\n * needs to be added or not (e.f., \\c -1 instead of \\c 0 or \\c NULL ) .\n * If the RTP extension management you need is not supported, it must be\n * added to the core to get it working.\n *\n * The janus_plugin_rtcp, instead, represents an RTCP packet, which may\n * contain one or more RTCP compound messages. The only info it contains\n * are whether it's related to the audio or video stream, and a pointer\n * to the data itself and its length. When creating a new packet, it should\n * be initialized with janus_plugin_rtcp_init. To make the generation of\n * some of the most common RTCP messages easier, a few helper core\n * callbacks are provided: this means that, while you can craft RTCP\n * messages yourself using the methods available in rtcp.h, it might be\n * easier to send, e.g., a keyframe request using the dedicated method,\n * which will leave the RTCP crafting process up tp the core.\n *\n * Finally, the janus_plugin_data represents a datachannel message. The\n * only info it contains are the label the message came from, a pointer\n * to the data itself and its length. When creating a new packet, it MUST\n * be initialized with janus_plugin_data_init.\n *\n */\n///@{\n/*! \\brief Janus plugin RTP extensions */\nstruct janus_plugin_rtp_extensions {\n\t/*! \\brief Audio level, in DB (0-127, 127=silence); -1 means no extension */\n\tint8_t audio_level;\n\t/*! \\brief Whether the encoder detected voice activity (part of audio-level extension)\n\t * @note Browsers apparently always set this to 1, so it's unreliable and should be ignored */\n\tgboolean audio_level_vad;\n\t/*! \\brief Video orientation rotation (0, 90, 180, 270); -1 means no extension */\n\tint16_t video_rotation;\n\t/*! \\brief Whether the video orientation extension says this is the back camera\n\t * @note Will be ignored if no rotation value is set */\n\tgboolean video_back_camera;\n\t/*! \\brief Whether the video orientation extension says it's flipped horizontally\n\t * @note Will be ignored if no rotation value is set */\n\tgboolean video_flipped;\n\t/*! \\brief Min and max playout delay, if available; -1 means no extension */\n\tint16_t min_delay, max_delay;\n\t/*! \\brief Length of Dependency Descriptor data, if available */\n\tuint8_t dd_len;\n\t/*! \\brief Dependency Descriptor content */\n\tuint8_t dd_content[256];\n\t/*! \\brief Absolute Capture Time timestamp */\n\tuint64_t abs_capture_ts;\n\t/*! \\brief Spatial and temporal layers, if available in a video-layers-allocation; -1 means no extension */\n\tint8_t spatial_layers, temporal_layers;\n};\n/*! \\brief Helper method to initialise/reset the RTP extensions field\n * @note This is important because each of the supported extensions may\n * use a different value to specify an \"extension missing\" state, which\n * may be different from a 0 or a NULL (e.g., a -1 instead)\n * @param[in] extensions Pointer to the janus_plugin_rtp_extensions instance to reset\n*/\nvoid janus_plugin_rtp_extensions_reset(janus_plugin_rtp_extensions *extensions);\n\n/*! \\brief Janus plugin RTP packet */\nstruct janus_plugin_rtp {\n\t/*! \\brief Index of the stream (relative to the SDP)\n\t * @note On outgoing packets you can set this to -1, to let the Janus\n\t * core find the first audio/video (depending on the \\c video property)\n\t * to send this on; notice that this tweak is only there for convenience,\n\t * and to make it easier for plugins not dealing with multistream, but\n\t * this shouldn't be relied upon too much as it may go away soon. */\n\tint mindex;\n\t/*! \\brief Whether this is an audio or video RTP packet */\n\tgboolean video;\n\t/*! \\brief The packet data */\n\tchar *buffer;\n\t/*! \\brief The packet length */\n\tuint16_t length;\n\t/*! \\brief RTP extensions */\n\tjanus_plugin_rtp_extensions extensions;\n};\n/*! \\brief Helper method to initialise/reset the RTP packet\n * @note The main motivation for this method comes from the presence of the\n * extensions as a janus_plugin_rtp_extensions instance.\n * @param[in] packet Pointer to the janus_plugin_rtp packet to reset\n*/\nvoid janus_plugin_rtp_reset(janus_plugin_rtp *packet);\n/*! \\brief Helper method to duplicate the RTP packet and its buffer\n * @note The core will always pass non-allocated packets to plugins, which\n * means they may have to duplicate them in case they need them for more time.\n * @param[in] packet Pointer to the janus_plugin_rtp packet to duplicate\n * @returns A pointer to the new janus_plugin_rtp, if successful, or NULL otherwise\n*/\njanus_plugin_rtp *janus_plugin_rtp_duplicate(janus_plugin_rtp *packet);\n\n/*! \\brief Janus plugin RTCP packet */\nstruct janus_plugin_rtcp {\n\t/*! \\brief Index of the stream (relative to the SDP)\n\t * @note On outgoing packets you can set this to -1, to let the Janus\n\t * core find the first audio/video (depending on the \\c video property)\n\t * to send this on; notice that this tweak is only there for convenience,\n\t * and to make it easier for plugins not dealing with multistream, but\n\t * this shouldn't be relied upon too much as it may go away soon. */\n\tint mindex;\n\t/*! \\brief Whether this is an audio or video RTCP packet */\n\tgboolean video;\n\t/*! \\brief The packet data */\n\tchar *buffer;\n\t/*! \\brief The packet length */\n\tuint16_t length;\n};\n/*! \\brief Helper method to initialise/reset the RTCP packet\n * @param[in] packet Pointer to the janus_plugin_rtcp packet to reset\n*/\nvoid janus_plugin_rtcp_reset(janus_plugin_rtcp *packet);\n\n/*! \\brief Janus plugin data message\n * @note At the moment, we only support text based datachannels.

More specifically, since Janus recordings (.mjr files) are basically a structured dump of RTP packets, this utility reorders them all and extracts the frames in order to stick them together and save them to a playable media file. No transcoding is done.\n.TP\nThe target file depends on the codec used in the recording: for instance, VP8 and VP9 frames can be converted to a either a .webm or .mkv file, while H.264 frames can only be converted to a .mp4 or .mkv file instead. Right now, you can convert VP8/VP9 recordings to .webm/.mkv, H.264/H.265/AV1 recordings to .mp4/.mkv, G.711/G.722 recordings to .wav, Opus recordings to .opus/.ogg/.mka, and Data Channel text recordings to .srt.

At the time\n * of writing, this helper has been integrated in several plugins in Janus.\n * To keep things simple on the Janus side, though, no processing\n * at all is done in the recording step: this means that the recorder\n * actually only dumps the RTP frames it receives to a file in a structured way,\n * so that they can be post-processed later on to extract playable media\n * files. This utility allows you to process those files, in order to\n * get a working media file you can playout with an external player.\n * The tool will generate a .webm/.mkv if the recording includes VP8 frames,\n * an .opus/.ogg/.mka if the recording includes Opus frames, an .mp4/.mkv if the\n * recording includes H.264/H.265/AV1 frames, and a .wav file if the recording includes\n * G.711 (mu-law or a-law) frames. In case the recording contains text\n * frames as received via data channels, instead, a .srt file will be\n * generated with the text content and the related timing information.\n *\n * Using the utility is quite simple.

Notice that network levels are simulated, and so are timestamps for when the packets have really been received, since that info is not stored in .mjr files. As such, its main purpose is helping analyze RTP packets, rather than investigate network issues.\n.TP\nThe tool requires two parameters: the path to the .mjr file to read, and a path to the target .pcap file. Notice that an attempt to process a non-RTP recording will result in an error.\n.SH EXAMPLES\n\\fBmjr2pcap rec1234.mjr rec1234.pcap\\fR \\- Convert the recording to pcap\n.SH BUGS\n.TP\nIf you think you found a bug or want to contribute a feature, you can issue or a pull request on https://github.com/meetecho/janus-gateway/issues.\n.TP\nAnyway, before doing that make sure you read the documentation at https://janus.conf.meetecho.com/docs/ and that it has not been discussed already at https://janus.discourse.group/. We only use Github for code issues, and \\fBNOT\\fR for configuration or usage issues: use the group for that.\n.SH SEE ALSO\n.TP\nhttps://github.com/meetecho/janus-gateway \\- Official repository\n.TP\nhttps://janus.conf.meetecho.com \\- Demos and documentation\n.TP\nhttps://janus.discourse.group/ \\- Community\n.TP\nhttps://www.meetecho.com/blog/ \\- Tutorials and blog posts on Janus\n.SH AUTHORS\nLorenzo Miniero (lorenzo@meetecho.com)\n"

Its main purpose is helping convert .pcap captures to media files, or make it easier to replay them via Janus.\n.TP\nThe tool requires a path to the .pcap file to read, and a path to the target .pcap file; besides, it needs info on the codec and the SSRC to filter. Notice that if the tool can't detect any RTP packet with that SSRC, it will result in an error: if you want the tool to autodetect an RTP stream, pass 0.\n.SH OPTIONS\n.TP\n.BR \\-h \", \" \\-\\-help\nPrint help and exit\n.TP\n.BR \\-V \", \" \\-\\-version\nPrint version and exit\n.TP\n.BR \\-c \", \" \\-\\-codec=\\fIcodec\\fR\nCodec the recording will contain (e.g., opus, vp8, etc.)\n.TP\n.BR \\-s \", \" \\-\\-ssrc=\\fISSRC (numeric)\\fR\nSSRC of the packets in the pcap file to save (pass 0 to autodetected)\n.TP\n.BR \\-w \", \" \\-\\-warnings\nShow warnings for skipped packets (e.g., not RTP or wrong SSRC)\n.SH EXAMPLES\n\\fBpcap2mjr -c opus -s 12345678 rec1234.pcap rec1234.mjr\\fR \\- Read all RTP packets with SSRC 12345678 from the provided .pcap file, and save them to a new .mjr file as an Opus recording\n.SH BUGS\n.TP\nIf you think you found a bug or want to contribute a feature, you can issue or a pull request on https://github.com/meetecho/janus-gateway/issues.\n.TP\nAnyway, before doing that make sure you read the documentation at https://janus.conf.meetecho.com/docs/ and that it has not been discussed already at https://janus.discourse.group/.

The \\c pcap2mjr tool is a simple utility\n * that allows you take .pcap network captures, extract a specific RTP\n * session via its SSRC, and convert it to an .mjr Janus recording instead.\n * Its main purpose is helping convert .pcap captures to media files, or\n * make it easier to replay them via Janus.\n *\n * Using the utility is quite simple. Just pass, as arguments to the tool,\n * the SSRC to extract, the codec used for the RTP packets originally, the\n * path to the .pcap source file, and the path to the destination file, e.g.:\n *\n\\verbatim\n./pcap2mjr -c vp8 -s 12345678 /path/to/source.pcap /path/to/destination.mjr\n\\endverbatim\n *\n * The SSRC is optional but recommended, since a pcap capture may contain\n * multiple streams, RTP or not, and so the tool might need help figuring\n * out which RTP stream specifically should be converted to .mjr. Omitting\n * the SSRC will instruct the tool to try and autodetect the first SSRC\n * it finds, and use that one as a filter.\n *\n * If the tool can't detect any RTP packet with the specified SSRC, itwill result in an error.\n *\n * \\ingroup postprocessing\n * \\ref postprocessing\n */\n\n#include <arpa/inet.h>\n#ifdef __MACH__\n#include <machine/endian.h>\n#else\n#include <endian.h>\n#endif\n#include <inttypes.h>\n#include <string.h>\n#include <stdlib.h>\n#include <signal.h>\n#include <sys/time.h>\n#include <netinet/ip.h>\n#include <netinet/ip6.h>\n#include <netinet/udp.h>\n#include <errno.h>\n\n#include <glib.h>\n#include <jansson.h>\n\n#include <pcap.h>\n#include <pcap/sll.h>\n\n#include \"../debug.h\"\n#include \"../version.h\"\n#include \"pp-rtp.h\"\n\n\n#define htonll(x) ((1==htonl(1)) ?

This implementation is heavily based on an excellent\n * <a href=\"http://nullprogram.com/blog/2015/02/17/\">blog post</a>\n * written by Chris Wellons.\n *\n * Objects interested in leveraging this reference counter mechanism\n * must add a janus_refcount instance as one of the members of the object\n * itself, and then call janus_refcall_init() to set it up. Initializing\n * the reference counter just needs a pointer to the function to invoke\n * when the object needs to be destroyed (counter reaches 0), while it\n * will automatically set the counter to 1. To increase and decrease the\n * counter just call janus_refcount_increase() and janus_refcount_decrease().\n * When the counter reaches 0, the function passed when initializing it will\n * be invoked: this means it's up to you to then free all the resources\n * the object may have allocated. Notice that if this involves other\n * objects that are reference counted, freeing the resource will just\n * mean decreasing the related counter, and not destroying it right away.\n *\n * The free function must be defined like this:\n *\n\\verbatim\nvoid my_free_function(janus_refcount *counter);\n\\endverbatim\n *\n * Since the reference counter cannot know the size of the object to be\n * freed, or where in the list of members the counter has been placed,\n * retrieving the pointer to the object to free is up to you, using the\n * janus_refcount_containerof macro.

GET requests instead are used for getting events\n * associated to a Janus session (and as such to all its plugin handles\n * and the events plugins push in the session itself), using a long poll\n * approach. A JavaScript library (janus.js) implements all of this on\n * the client side automatically.\n * \\note There's a well known bug in libmicrohttpd that may cause it to\n * spike to 100% of the CPU when using HTTPS on some distributions.

Right now, you can only configure\n * the address of the MQTT broker to use, and the queues to\n * make use of to receive (to-janus) and send (from-janus) messages\n * from/to an external application. As with WebSockets, considering that\n * requests wouldn't include a path to address some mandatory information,\n * these requests addressed to Janus should include as part of their payload,\n * when needed, additional pieces of information like \\c session_id and\n * \\c handle_id. That is, where you'd send a Janus request related to a\n * specific session to the \\c /janus/\\<session> path, with MQTT\n * you'd have to send the same request with an additional \\c session_id\n * field in the JSON payload.\n * \\note When you create a session using MQTT, a subscription to the\n * events related to it is done automatically through the outgoing queue,\n * so no need for an explicit request as the GET in the plain HTTP API.\n *\n * \\ingroup transports\n * \\ref transports\n */\n\n#include \"transport.h\"\n\n#include <MQTTAsync.h>\n\n#include \"../debug.h\"\n#include

This means that, with the help of this module, local\n * applications can use Unix Sockets to make requests to Janus.\n * This plugin can make use of either the \\c SOCK_SEQPACKET or the\n * \\c SOCK_DGRAM socket type according to what you configure, so make\n * sure you're using the right one when writing a client application.\n * Pretty much as it happens with WebSockets, the same client socket can\n * be used for both sending requests and receiving notifications, without\n * any need for long polls. At the same time, without the concept of a\n * REST path, requests sent through the Unix Sockets interface will need\n * to include, when needed, additional pieces of information like\n * \\c session_id and \\c handle_id. That is, where you'd send a Janus\n * request related to a specific session to the \\c /janus/\\<session> path,\n * with Unix Sockets you'd have to send the same request with an additional\n * \\c session_id field in the JSON payload. The same applies for the handle.\n * \\note When you create a session using Unix Sockets, a subscription to\n * the events related to it is done automatically, so no need for an\n * explicit request as the GET in the plain HTTP API. Closing a client\n * Unix Socket will also destroy all the sessions it created.\n *\n * \\ingroup transports\n * \\ref transports\n */\n\n#include \"transport.h\"\n\n#include <arpa/inet.h>\n#include

Support for this is planned, though (e.g., through some kind\n * of negotiation to create queues on the fly). Right now, you can only\n * configure the address of the RabbitMQ server to use, and the queues to\n * make use of to receive (to-janus) and send (from-janus) messages\n * from/to an external application. As with WebSockets, considering that\n * requests wouldn't include a path to address some mandatory information,\n * these requests addressed to Janus should include as part of their payload,\n * when needed, additional pieces of information like \\c session_id and\n * \\c handle_id. That is, where you'd send a Janus request related to a\n * specific session to the \\c /janus/\\<session> path, with RabbitMQ\n * you'd have to send the same request with an additional \\c session_id\n * field in the JSON payload.\n * \\note When you create a session using RabbitMQ, a subscription to the\n * events related to it is done automatically through the outgoing queue,\n * so no need for an explicit request as the GET in the plain HTTP API.\n *\n * \\ingroup transports\n * \\ref transports\n */\n\n#include \"transport.h\"\n\n/* Latest RabbitMQ-C library changes the library

In that case, the same\n * WebSocket can be used for both sending requests and receiving\n * notifications, without the need for long polls. At the same time,\n * without the concept of a REST path, requests sent through the\n * WebSockets interface will need to include, when needed, additional\n * pieces of information like \\c session_id and \\c handle_id. That is,\n * where you'd send a Janus request related to a specific session to the\n * \\c /janus/\\<session> path, with WebSockets you'd have to send the same\n * request with an additional \\c session_id field in the JSON payload.\n * The same applies for the handle. The JavaScript library (janus.js)\n * implements all of this on the client side automatically.\n * \\note When you create a session using WebSockets, a subscription to\n * the events related to it is done automatically, so no need for an\n * explicit request as the GET in the plain HTTP API. Closing a WebSocket\n * will also destroy all the sessions it created.\n *\n * \\ingroup transports\n * \\ref transports\n */\n\n#include \"transport.h\"\n\n#include <arpa/inet.h>\n#include

The structures to make the communication possible are\n * defined here as well.\n *\n * In particular, the Janus core implements the \\c janus_transport_callbacks\n * interface. This means that, as a transport plugin, you can use the\n * methods it exposes to contact the core, e.g., in order to notify\n * an incoming message. In particular, the methods the core exposes\n * to transport plugins are:\n *\n * - \\c incoming_request(): to notify an incoming JSON message/event\n * from one of the transport clients.\n *\n * On the other hand, a transport plugin that wants to register at the\n * Janus core needs to implement the \\c janus_transport interface. Besides,\n * as a transport plugin is a shared object, and as such external to the\n * core itself, in order to be dynamically loaded at startup it needs\n * to implement the \\c create_t() hook as well, that should return a\n * pointer to the plugin instance. This is an example of such a step:\n *\n\\verbatim\nstatic janus_transport mytransport = {\n\t[..]\n};\n\njanus_transport *create(void) {\n\tJANUS_LOG(LOG_VERB, , \"%s created!\\n\", MY_TRANSPORT_NAME);\n\treturn &mytransport;\n}\n\\endverbatim\n *\n * This will make sure that your transport plugin is loaded at startup\n * by the Janus core, if it is deployed in the proper folder.\n *\n * As anticipated and described in the above example, a transport plugin\n * must basically be an instance of the \\c janus_transport type. As such,\n * it must implement the following methods and callbacks for the core:\n *\n * - \\c init(): this is called by the Janus core as soon as your transport\n * plugin is started; this is where you should setup your transport plugin\n * (e.g., static stuff and reading the configuration file);\n * - \\c destroy(): on the other hand, this is called by the core when it\n * is shutting down, and your transport plugin should too;\n * - \\c get_api_compatibility(): this method MUST return JANUS_TRANSPORT_API_VERSION;\n * - \\c get_version(): this method should return a numeric version identifier (e.g., 3);\n * - \\c get_version_string(): this method should return a verbose version identifier (e.g., \"v1.0.1\");\n * - \\c get_description(): this method should return a verbose description of your transport plugin (e.g., \"This is my avian carrier transport plugin for the Janus API\");\n * - \\c get_name(): this method should return a short display name for your transport plugin (e.g., \"My Amazing Transport\");\n * - \\c get_package(): this method should return a unique package identifier for your transport plugin (e.g., \"janus.transport.mytransport\");\n * - \\c is_janus_api_enabled(): this method should return TRUE if Janus API can be used with this transport, and support has been enabled by the user;\n * - \\c is_admin_api_enabled(): this method should return TRUE if Admin API can be used with this transport, and support has been enabled by the user;\n * - \\c send_message(): this method asks the transport to send a message (be it a response or an event) to a client on the specified transport;\n * - \\c session_created(): this method notifies the transport that a Janus session has been created by one of its requests;\n * - \\c session_over(): this method notifies the transport that one of its Janus sessionss is now over, whether because of a timeout or not.\n * - \\c session_claimed(): this method notifies the transport that it has claimed a session.\n *\n * All the above methods and callbacks are mandatory: the Janus core will\n * reject a transport plugin that doesn't implement any of the\n * mandatory callbacks.\n *\n * The Janus core \\c janus_transport_callbacks interface is provided to a\n * transport plugin, together with the path to the configurations files\n * folder, in the \\c init() method. This path can be used to read and\n * parse a configuration file for the transport plugin: the transport\n * plugins we made available out of the box use the package name as a\n * name for the file (e.g., \\c janus.transport.http.cfg for the HTTP/HTTPS\n * transport plugin), but you're free to use a different one, as long\n * as it doesn't collide with existing ones. Besides, the existing transport\n * plugins use the same INI format for configuration files the core\n * uses (relying on the \\c janus_config helpers for the purpose) but\n * again, if you prefer a different format (XML, JSON, etc.) that's up to you.\n *\n * \\ingroup transportapi\n * \\ref transportapi\n */\n\n#ifndef JANUS_TRANSPORT_H\n#define JANUS_TRANSPORT_H\n\n#include <stdlib.h>\n#include <stdint.h>\n#include <stdio.h>\n#include <string.h>\n#include <ctype.h>\n#include <unistd.h>\n#include <inttypes.h>\n\n#include <glib.h>\n#include <jansson.h>\n\n#include \"../refcount.h\"\n\n\n/*!
