License\n\nBy contributing to mediasoup, you agree that your contributions will be licensed under its ISC License.\n\n## Reporting Bugs\n\nWe primarily use GitHub as an issue tracker. Just open an issue in GitHub if you have encountered a bug in mediasoup.\n\nIf you have questions or doubts about mediasoup or need support, please use the mediasoup Discourse Group instead:\n\n- https://mediasoup.discourse.group\n\nIf you got a crash in mediasoup, please try to provide a core dump into the issue report:\n\n- https://mediasoup.org/support/#crashes-in-mediasoup-get-a-core-dump\n\n## Pull Request Process\n\nWhen creating a Pull Request for mediasoup:\n\n- Ensure that changes/additions done in TypeScript files (in `node/src` folder) are also applied to the Rust layer (in `rust` folder), and vice-versa.\n- Test units must be added for both Node.js and Rust.\n- Changes/additions in C++ code may need tests in `worker/test` folder.\n\nOnce all changes are done, run the following commands to verify that the code in your PR conforms to the code syntax of the project, it does not break existing funtionality and tests pass:\n\n- `npm run lint`: Check TypeScript and C++ linting rules. Formating errors can be automatically fixed by running `npm run format`.\n- `npm run typescript:build`: Compile TypeScript code (under `src` folder) into JavaScript code (under `lib` folder).\n- `npm run test`: Run JavaScript and C++ test units.\n- Instead, you can run `npm run release:check` which will run all those steps.\n- `cargo fmt`, `cargo clippy` and `cargo test` to ensure that everything is good in Rust side.\n\nThe full list of `npm` scripts, `invoke` tasks and `cargo` commands is available in the [doc/Building.md](/doc/Building.md) file.\n\n## Coding Style\n\nIn adition to automatic checks performed by commands above, we also enforce other minor things related to coding style:\n\n### Comments in TypeScript and C++\n\nWe use `//` for inline comments in both JavaScript and C++ source files.\n\n- Comments must start with upercase letter.\n- Comments must not exceed 80 columns (split into different lines if necessary).\n- Comments must end with a dot.\n\nExample (good):\n\n```ts\n// Calculate foo based on bar value.\nconst foo = bar / 2;\n```\n\nExample (bad):\n\n```ts\n// calculate foo based on bar value\nconst foo = bar / 2;\n```\n\nWhen adding inline documentation for methods or functions, we use `/** */` syntax. Example:\n\n```ts\n/**\n * Calculates current score for foo and bar.\n */\nfunction calculateScore(): number {\n\t// [...]\n}\n```\n" }, { "path": "Cargo.toml", "content": "[workspace]\nresolver = \"2\"\nmembers = [\n \"rust\",\n \"rust/types\",\n \"worker\"\n]\n" }, { "path": "LICENSE", "content": "ISC License\n\nCopyright © 2015, Iñaki Baz Castillo \n\nPermission to use, copy, modify, and/or distribute this software for any\npurpose with or without fee is hereby granted, provided that the above\ncopyright notice and this permission notice appear in all copies.\n\nTHE SOFTWARE IS PROVIDED \"AS IS\" AND THE AUTHOR DISCLAIMS ALL WARRANTIES\nWITH REGARD TO THIS SOFTWARE INCLUDING ALL IMPLIED WARRANTIES OF\nMERCHANTABILITY AND FITNESS.

Requirements for it to work:\n\n- \"version\" field in `package.json` must have been incremented (and not commited to Git).\n- `CHANGELOG.md` file must have been updated with an entry matching the new version.\n- Of course, permissions to publish in NPM registry are required.\n\n## Rust\n\nThe only special feature in Rust case is special environment variable \"KEEP_BUILD_ARTIFACTS\", that when set to \"1\" will allow incremental recompilation of changed C++ sources during hacking on mediasoup.\n\nIt is not necessary for normal usage of mediasoup as a dependency.\n\n## Python Invoke and `tasks.py` file\n\nmediasoup uses Python [Invoke](https://www.pyinvoke.org) library for managing and organizing tasks in the `worker` folder (mediasoup worker C++ subproject). `Invoke` is basically a replacemente of `make` + `Makefile` written in Python. mediasoup automatically installs `Invoke` in a local custom path during the installation process (in both Node and Rust) so the user doesn't need to worry about it.\n\nTasks are defined in `worker/tasks.py`. For development purposes, developers or contributors can install `Invoke` using `pip3 install invoke` and run tasks below within the `worker` folder.\n\nSee all the tasks by running `invoke --list` within the `worker` folder.\n\n_NOTE:_ For some of these tasks to work, npm dependencies of `worker/scripts/package.json` must be installed:\n\n```bash\nnpm ci --prefix worker/scripts\n```\n\n### `invoke` (default task)\n\nAlias of `invoke mediasoup-worker` task below.\n\n### `invoke meson-ninja`\n\nInstalls `meson` and `ninja` into a local custom path.\n\n### `invoke clean`\n\nCleans built objects and binaries.\n\n### `invoke clean-build`\n\nCleans built objects and other artifacts, but keeps `mediasoup-worker` binary in place.\n\n### `invoke clean-pip`\n\nCleans `meson` and `ninja` installed in local prefix with pip.\n\n### `invoke clean-subprojects`\n\nCleans subprojects downloaded with Meson.\n\n### `invoke clean-all`\n\nCleans built objects and binaries, `meson` and `ninja` installed in local prefix with pip and all subprojects downloaded with Meson.\n\n### `invoke update-wrap-file [subproject]`\n\nUpdates the wrap file of a subproject (those in `worker/subprojects` folder) with Meson. After updating it, `invoke setup` must be called by passing `MESON_ARGS=\"--reconfigure\"` environment variable. Usage example:\n\n```bash\ncd worker\ninvoke update-wrap-file openssl\nMESON_ARGS=\"--reconfigure\" invoke setup\n```\n\n### `invoke mediasoup-worker`\n\nBuilds the `mediasoup-worker` binary at `worker/out/Release`.\n\nIf the \"MEDIASOUP_MAX_CORES\" environment variable is set, the build process will use that number of CPU cores. Otherwise it will auto-detect the number of cores in the machine.\n\n\"MEDIASOUP_BUILDTYPE\" environment variable controls build types, \"Release\" and \"Debug\" are presets optimized for those use cases. Other build types are possible too, but they are not presets and will require \"MESON_ARGS\" use to customize build configuration.\n\nCheck the meaning of useful macros in the `worker/include/Logger.hpp` header file if you want to enable tracing or other debug information.\n\nBinary is built at `worker/out/MEDIASOUP_BUILDTYPE/build`.\n\nIn order to instruct the mediasoup Node.js module to use the \"Debug\" mediasoup-worker` binary, an environment variable must be set before running the Node.js application:\n\n```bash\nMEDIASOUP_BUILDTYPE=Debug node myapp.js\n```\n\nIf the \"MEDIASOUP_WORKER_BIN\" environment variable is set (it must be an absolute file path), mediasoup will use the it as `mediasoup-worker` binary and **won't** compile the binary:\n\n```bash\nMEDIASOUP_WORKER_BIN=\"/home/xxx/src/foo/mediasoup-worker\" node myapp.js\n```\n\n### `invoke libmediasoup-worker`\n\nBuilds the `libmediasoup-worker` static library at `worker/out/Release`.\n\n\"MEDIASOUP_MAX_CORES\"` and \"MEDIASOUP_BUILDTYPE\" environment variables from above still apply for static library build.\n\n### `invoke xcode`\n\nBuilds a Xcode project for the mediasoup worker subproject.\n\n### `invoke lint`\n\nValidates mediasoup worker C++ files using [clang-format](https://clang.llvm.org/docs/ClangFormat.html) and rules in `worker/.clang-format`.\n\n**Requirements:**\n\n- A specific version of `clang-format`is required. See [Install clang-format](#install-clang-format).\n- `clang-format-VERSION` or `clang-format` (corresponding to the required version) must be in the `PATH`. If not, add it before running the command.\n\n### `invoke format`\n\nRewrites mediasoup worker C++ files using [clang-format](https://clang.llvm.org/docs/ClangFormat.html).\n\n**Requirements:**\n\n- A specific version of `clang-format`is required. See [Install clang-format](#install-clang-format).\n- `clang-format-VERSION` or `clang-format` (corresponding to the required version) must be in the `PATH`. If not, add it before running the command.\n\n### `invoke tidy`\n\nRuns [clang-tidy](http://clang.llvm.org/extra/clang-tidy) and performs C++ code checks following `worker/.clang-tidy` rules.\n\n**Requirements:**\n\n- `invoke clean` must have been called first.\n- A specific version of `clang-tidy`is required. See [Install clang-tidy](#install-clang-tidy).\n- `clang-tidy-VERSION` or `clang-tidy` (corresponding to the required version) must be in the `PATH`. If not, add it before running the command. Same for other `clang-tidy` related executables such as `run-clang-tidy` and `clang-apply-replacements`,\n\n**Environment variables:**\n\n- \"MEDIASOUP_TIDY_CHECKS\": Optional. Comma separated list of checks. Overrides the checks defined in `worker/.clang-tidy` file.\n- \"MEDIASOUP_TIDY_FILES\": Optional. Space separated source file paths to process. All `.cpp` files will be processes by default.\n - File paths must be relative to `worker/` folder.\n - File paths can use [glob](https://github.com/isaacs/node-glob) syntax. Example: `\"src/RTC/SCTP/**/*.cpp\"`.\n\n**Usage example in macOS:**\n\n```bash\nPATH=\"/opt/homebrew/opt/llvm/bin/:$PATH\" invoke tidy\n```\n\nIt may happens that `clang-tidy` doesn't know where C++ standard libraries are so it shows lot of warnings about them. Depending on your local setup this may work:\n\n```bash\nPATH=\"/opt/homebrew/opt/llvm/bin/:$PATH\" CPATH=/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/include/c++/v1 invoke tidy\n```\n\n### `invoke tidy-fix`\n\nSame as `invoke tidy` but it also applies fixes.\n\n### `invoke test`\n\nBuilds and runs the `mediasoup-worker-test` binary at `worker/out/Release` (or at `worker/out/Debug` if the \"MEDIASOUP_BUILDTYPE\" environment variable is set to \"Debug\"), which uses [Catch2](https://github.com/catchorg/Catch2) to run test units located at `worker/test` folder.\n\n### `invoke test-asan-address`\n\nRun test with Address Sanitizer with `-fsanitize=address`.\n\n### `invoke test-asan-undefined`\n\nRun test with Address Sanitizer with `-fsanitize=undefined`.\n\n### `invoke fuzzer`\n\nBuilds the `mediasoup-worker-fuzzer` binary (which uses [libFuzzer](http://llvm.org/docs/LibFuzzer.html)) at `worker/out/Release` (or at `worker/out/Debug/` if the \"MEDIASOUP_BUILDTYPE\" environment variable is set to \"Debug\").\n\n**Requirements:**\n\n- Linux with fuzzer capable clang++.\n- \"CC\" environment variable must point to `clang`.\n- \"CXX\" environment variable must point to `clang++`.\n\nRead the [Fuzzer](Fuzzer.md) documentation for detailed information.\n\n### `invoke fuzzer-run-all`\n\nRuns all fuzzer cases.\n\n### `invoke docker`\n\nBuilds a Linux Ubuntu Docker image with fuzzer capable clang++ and all dependencies to run mediasoup.\n\n### `invoke docker-run`\n\nRuns a container of the Ubuntu Docker image created with `invoke docker`. It automatically executes a `bash` session in the mediasoup directory, which is a Docker volume that points to the mediasoup root folder.\n\n**NOTE:** To install and run mediasoup in the container, previous installation (if any) must be properly cleaned by entering the `worker` directory and running `invoke clean-all`.\n\n### `invoke docker-alpine`\n\nBuilds a Linux Alpine Docker image with all dependencies to run mediasoup.\n\n### `invoke docker-alpine-run`\n\nRuns a container of the Alpine Docker image created with `invoke docker-alpine`. It automatically executes an `ash` session in the mediasoup directory, which is a Docker volume that points to the mediasoup root folder.\n\n**NOTE:** To install and run mediasoup in the container, previous installation (if any) must be properly cleaned by entering the `worker` directory and running `invoke clean-all`.\n\n### `invoke docker-386`\n\nBuilds a 386 Linux Debian (32 bits arch) Docker image with all dependencies to run mediasoup.\n\n### `invoke docker-alpine-386`\n\nRuns a container of the 386 Linux Debian (32 bits arch) Docker image created with `invoke docker-386`. It automatically executes an `ash` session in the mediasoup directory, which is a Docker volume that points to the mediasoup root folder.\n\n**NOTE:** To install and run mediasoup in the container, previous installation (if any) must be properly cleaned by entering the `worker` directory and running `invoke clean-all`.\n**NOTE:** Due to the very old Node v18 in this image, in order to run mediasoup Node tests, `npm ci` must be executed with `--ignore-scripts --engine-strict=false` arguments.\n\n## Makefile\n\nThe `worker` folder contains a `Makefile` file for the mediasoup worker C++ subproject. It acts as a proxy to the `Invoke` tasks defined in `tasks.py`. The `Makefile` file exists to help developers or contributors that prefer keep using `make` commands.\n\nAll tasks defined in `tasks.py` (see above) are available in `Makefile`. There is only one exception:\n\n- The `update-wrap-file` needs a \"SUBPROJECT\" environment variable indicating the subproject to update. Usage example:\n ```bash\n cd worker\n make update-wrap-file SUBPROJECT=openssl\n ```\n\n## Install clang-format\n\nA specific `clang-format` version is required to be installed in the system, which is defined in [clang-scripts.mjs](../worker/scripts/clang-scripts.mjs).\n\nmacOS:\n\n```bash\nbrew install clang-format@VERSION\n```\n\nLinux:\n\n```bash\napt-get install clang-format-VERSION\n```\n\n## Install clang-tidy\n\nA specific `clang-tidy` version is required to be installed in the system, which is defined in [clang-scripts.mjs](../worker/scripts/clang-scripts.mjs).\n\nmacOS:\n\n```bash\nbrew install clang-tidy@VERSION\n```\n\nLinux:\n\n```bash\napt-get install clang-tidy-VERSION\n```\n" }, { "path": "doc/Charts.md", "content": "# Charts\n\n## Broadcasting\n\nmediasoup **v2** (a room uses a single media worker subprocess by design, so a single CPU).\n\nCharts provided by [CoSMo](https://www.cosmosoftware.io) team.\n\nScenario:\n\n- 1 peer producing audio and video tracks.\n- N spy peers receiving them.\n\n#### Bandwidth out (Mbps) / number of viewers\n\n![](charts/mediasoup_SFU_BW_out.png)\n\n#### Packets per second / number of viewers\n\n![](charts/mediasoup_SFU_packetspersec.png)\n\n#### Average bitrate (bps) and googRTT (ms) / number of viewers\n\n![](charts/mediasoup_clients_getstats.png)\n\n#### CPU usage / number of viewers\n\n![](charts/mediasoup_SFU_cpu.png)\n" }, { "path": "doc/Closures.md", "content": "# Closures\n\nSome considerations:\n\n- Any JS `xxxxx.yyyyyClosed()` method is equivalent to the corresponding C++ `~Xxxxx()` destructor.

They should be use to feed fuzzer with appropriate input.\n\nHowever, given how `libFuzzer` [works](http://llvm.org/docs/LibFuzzer.html#options), the first directory given as command line parameter is not just used for reading corpus files, but also to store newly generated ones. So, it's recommended to pass `fuzzer/new-corpus` as first directory.

Those files can be individually used later (instead of passing corpus directories) to the fuzzer to verify that the issue has been fixed.\n\nThe `fuzzer/reports` directory should be used to store those new crash reports.

You can bump them all, but it is not required.\n- If `mediasoup-sys`'s API changes in a breaking way, then its minor version needs to be changed, otherwise patch version needs to be changed. Same for `mediasoup-types` crate.\n\n**Important:** Adding new APIs that `mediasoup` crate has to understand to continue working normally is a breaking change because it'll start crashing/printing errors if unexpected things happen.\n\n## Steps to publish new mediasoup crates\n\n1. Update versions in `worker/Cargo.toml` (for `mediasoup-sys` crate), `rust/types/Cargo.toml` (for `mediasoup-types` crate) and `rust/Cargo.toml` (for `mediasoup` crate). Note that in `rust/Cargo.toml` you may need to update the version of `[dependencies.mediasoup-sys]` and/or `[dependencies.mediasoup-types]` if it also changed.\n2. Update `rust/CHANGELOG.md`.\n3. Run `cargo build` to reflect changes in `Cargo.lock`.\n4. Create PR and have it merged in mediasoup main branch.\n5. Upload Git tags (the new one in `rust/CHANGELOG.md`, so the new `mediasoup` crate version):\n\n```sh\ngit tag -a rust-X.X.X -m rust-X.X.X\ngit push origin rust-X.X.X\n```\n\n6. Publish crates (you need an account and permissions and so on):\n\n```sh\ncd rust/types\ncargo publish\n\ncd worker\ncargo publish\n\ncd rust\ncargo publish\n```\n\n## Notes\n\n- Depending on the state in `worker` directory you may need to run `invoke clean-all` or `make clean-all` in `worker` directory first.\n- `cargo publish` will create the crate package, check if all necessary dependencies are already present on [crates.io](https://crates.io/), will then compile the package (to ensure that you don't publish a broken version) and will upload it to [crates.io](https://crates.io/).\n- Never publish from random branches or local state that is not on GitHub. If you have local files modified Cargo will refuse to publish until you commit all the changes.\n\n## Extras\n\n### Check crate without publishing\n\nIf you want to do everything except publishing itself, `cargo package` command exists. You can also run `cargo package --dry-run` to avoid package generation or `cargo publish --dry-run`.\n\n### Update required Rust version\n\nUsing `rustup` command:\n\n```sh\nrustup update\n```\n" }, {

Rust port of [mediasoup](https://github.com/versatica/mediasoup) TypeScript library!\n//!\n//! For general information go to readme in repository.\n//!\n//! # For TypeScript users\n//! If you were using mediasoup in TypeScript before, most of the API should be familiar to you.\n//! However, this is not one-to-one port, API was adjusted to more idiomatic Rust style leveraging\n//! powerful type system and ownership system to make API more robust and more misuse-resistant.\n//!\n//! So you will find specific types in most places where plain strings were used, instead of\n//! `close()` you will see `Drop` implementation for major entities that will close everything\n//! gracefully when it goes out of scope.\n//!\n//! # Before you start\n//! This is very low-level **library**. Which means it doesn't come with a ready to use signaling\n//! mechanism or easy to customize app scaffold (see\n//! [design goals](https://github.com/versatica/mediasoup/tree/v3/rust/readme.md#design-goals)).\n//!\n//! It is recommended to visit mediasoup website and read\n//! [design overview](https://mediasoup.org/documentation/v3/mediasoup/design/) first.\n//!\n//! There are some requirements for building underlying C++ `mediasoup-worker`, please find them in\n//! [installation instructions](https://mediasoup.org/documentation/v3/mediasoup/installation/)\n//!\n//! # Examples\n//! There are some examples in `examples` and `examples-frontend` directories (for server- and\n//! client-side respectively), you may want to look at those to get a general idea of what API looks\n//! like and what needs to be done in what order (check WebSocket messages in browser DevTools for\n//! better understanding of what is happening under the hood).\n//!\n//! # How to start\n//! With that in mind, you want start with creating [`WorkerManager`](worker_manager::WorkerManager)\n//! instance and then 1 or more workers. Workers a responsible for low-level job of sending media\n//! and data back and forth. Each worker is backed by single-core C++ worker thread. On each worker\n//! you create one or more routers that enable injection, selection and forwarding of media and data\n//! through [`transport`] instances. There are a few different transports available, but most likely\n//! you'll want to use [`WebRtcTransport`](webrtc_transport::WebRtcTransport) most often. With\n//! transport created you can start creating [`Producer`](producer::Producer)s to send data to\n//! [`Router`](router::Router) and [`Consumer`](consumer::Consumer) instances to extract data from\n//! [`Router`](router::Router).\n//!\n//! Some of the more advanced cases involve multiple routers and even workers that can user more\n//! than one core on the machine or even scale beyond single host. Check\n//! [scalability page](https://mediasoup.org/documentation/v3/scalability/) of the official\n//! documentation.\n//!\n//! Please check integration and unit tests for usage examples, they cover all major functionality\n//! and are a good place to start until we have demo apps built in Rust).\n\npub use mediasoup_types as types;\nmod data_structures;\npub(crate) mod fbs;\nmod macros;\nmod messages;\n#[doc(hidden)]\npub mod ortc;\npub mod prelude;\npub mod router;\nmod rtp_parameters;\nmod sctp_parameters;\nmod srtp_parameters;\npub mod supported_rtp_capabilities;\npub mod webrtc_server;\npub mod worker;\npub mod worker_manager;\n\npub mod audio_level_observer {\n //!

If only one of the input types is statically\n// guaranteed to be able to represent the result, the return type is that type;\n// if either one would do, the result type is the smaller type. (One of these\n// two cases always applies.)\n//\n// * The case with one floating-point and one integral type is not allowed,\n// because the floating-point type will have greater range, but may not\n// have sufficient precision to represent the integer value exactly.)\n//\n// Clamp (a.k.a. constrain to a given interval)\n// ============================================\n//\n// rtc::SafeClamp(x, a, b)\n//\n// Accepts three arguments of any mix of integral types or any mix of\n// floating-point types, and returns the value in the closed interval [a, b]\n// that is closest to x (that is, if x < a it returns a; if x > b it returns b;\n// and if a <= x <= b it returns x). As for SafeMin() and SafeMax(), there is\n// no truncation or wrap-around. The result type\n//\n// 1. is statically guaranteed to be able to represent the result;\n//\n// 2. is no larger than the largest of the three argument types; and\n//\n// 3. has the same signedness as the type of the first argument, if this is\n// possible without violating the First or Second Law.\n//\n// There is always at least one type that meets criteria 1 and 2. If more than\n// one type meets these criteria equally well, the result type is one of the\n// types that is smallest. Note that unlike SafeMin() and SafeMax(),\n// SafeClamp() will sometimes pick a return type that isn't the type of any of\n// its arguments.\n//\n// * In this context, a type A is smaller than a type B if it has a smaller\n// range; that is, if A::max() - A::min() < B::max() - B::min(). For\n// example, int8_t < int16_t == uint16_t < int32_t, and all integral types\n// are smaller than all floating-point types.)\n//\n// * As for SafeMin and SafeMax, mixing integer and floating-point arguments\n// is not allowed, because floating-point types have greater range than\n// integer types, but do not have sufficient precision to represent the\n// values of most integer types exactly.\n//\n// Requesting a specific return type\n// =================================\n//\n// All three functions allow callers to explicitly specify the return type as a\n// template parameter, overriding the default return type. E.g.\n//\n// rtc::SafeMin(x, y) // returns an int\n//\n// If the requested type is statically guaranteed to be able to represent the\n// result, then everything's fine, and the return type is as requested.

"content": "# webrtc-fuzzer-corpora\n\nThis repository contains [libFuzzer](http://libfuzzer.info) corpus files useful for WebRTC developers to test their implementations.\n\nThe `corpora` folders contains subfolders with corpus files.\n\nSome corpus files are taken from the Chromium project (those into the [webrtc/test/fuzzer/](https://chromium.googlesource.com/external/webrtc/+/master/test/fuzzers/corpora/) folder), so credits to the Chromium guys.\n\nThe `reports` folder contains some relevant fuzzer generated crash and memory leak reports contributed by the community.\n\n\n## SHA1 hash and file duplicates\n\nIt is desiderable to avoid duplicate files in this repository in order to not pollute the folders with samples that might lead to usless testing iterations (e.g. file with different names but same binary content).\n\nTo help managing this kind of issues, the script `add_sha1.sh` can be used to append the sha1 hashsum to the corpora and results files.\n\n```\n$ ./add_sha1.sh .\nrenamed './corpora/agc-corpus/agc-1' -> './corpora/agc-corpus/agc-1-b35a35f11d86e802f694f84c45e48da96158f73f'\nrenamed './corpora/agc-corpus/agc-2' -> './corpora/agc-corpus/agc-2-f3d59a997d30890da3239b377bba3bc502d18f1e'\n...\nrenamed './corpora/rtcp-corpus/0.rtcp' -> './corpora/rtcp-corpus/0-01b13c2eb549daadeec1eb7eb0846e9a2f5729eb.rtcp'\n```\n\nTarget folder can be specified as first input. File extensions will not be touched.\n\nThe script will detect an already hashed file by looking for the sha1sum in the filename. In this cases the output will be like:\n\n```\n> ./add_sha1.sh . | grep OK\n./corpora/pseudotcp-corpus/785b96587d0eb44dd5d75b7a886f37e2ac504511 -> OK\n./corpora/rtcp-corpus/0-01b13c2eb549daadeec1eb7eb0846e9a2f5729eb.rtcp -> OK\n./corpora/rtp-corpus/rtp-0-951641f47532884149e6ebe9a87386226d8bf4fe -> OK\n```\n\nThis script will alse reveal duplicate files in the same subfolder by matching the file sha1sum with other files names:\n\n```\n> ./add_sha1.sh . | grep DUPLICATE\n./corpora/rtp-corpus/rtp-4 -> DUPLICATE ./corpora/rtp-corpus/rtp-1-5a709d82364ddf4f9350104c83994dded1c9f91c\n./corpora/sdp-corpus/4.sdp -> DUPLICATE ./corpora/sdp-corpus/2-60495c33fc8758c5ce44f896c5f508bc026842c2.sdp\n./corpora/sdp-corpus/8.sdp -> DUPLICATE ./corpora/sdp-corpus/2-60495c33fc8758c5ce44f896c5f508bc026842c2.sdp\n```\n\nAnyway `add_sha1` will only detect duplicates in the same subfolder.\nAnother way to quickly reveal file duplicates across all subfolders is the following command:\n\n```\n> find . \\( ! -regex '.*/\\..*' \\) -type f -exec sha1sum {} + | sort | uniq -w40 -dD\n131d620296fa9eb2c372c7fd71b8e58f8a10abd5

"content": "# TODO STCP\n\n## Related to mediasoup SCTP implementation\n\n- dcsctp uses µs (webrtc::Timestamp::Micros()) internally, while mediasoup uses ms (`DepLibUV::GetTimeMs()`). When porting dcsctp timeout/duration logic, make sure to convert accordingly. Do not mix units in the same field.\n\n- `Association`: When transitioning to CLOSED (due to failure while connecting or closure) we should emit a new event \"stcpclosed\" in all `DataProducers/Consumers`.\n\n- When receiving SCTP RE-CONFIG, we should emit \"streamclosed\" in those `DataProducers/DataConsumers` whose stream ID have been closed.\n\n- `OnAssociationFailed()` and `OnAssociationClosed()` should report an error (if present) to JS.\n\n- Rename all \"Packet\", \"Chunk\", \"Parameter\", \"Error Cause\", \"Association\", etc to lowcase everywhere (in code and comments).\n\n- Rename all \"I_DATA\" etc to `I-DATA\" everywhere (in code and comments).\n\n- Probably add many more fields in `SctpOptions` given to the `Association` in `Transport.cpp`.\n\n- When running `test-PipeTransport.ts` and `test-werift-sctp.ts` with `useBuiltInSctpStack: true`, tests pass but those errors show up:\n\n ```\n mediasoup:ERROR:Worker (stderr) UnixStreamSocketHandle::Write() | uv_try_write() failed, trying uv_write(): broken pipe\n ```\n\n- We must remove `numSctpStreams` option given to `router.createXxxTransport()` and `NumSctpStreams` type. `OS` and `MIS` in `numSctpStreams` are just the max announced number of outbound and incoming SCTP streams, but in the new SCTP stack those should always be 65535. The max number of incoming and outgoing streams will be negotiated later with the SCTP INIT and INIT_ACK and will be the minimum of our values (65535) and the OS and MIS that the peer announces in its INIT or INIT_ACK.\n - This is a breaking change.\n - Remove it from `sctpParameters.fbs` and other FBS types (look for `MIS` or `mis`, etc).\n - Remove it in Rust layer.\n - We must also remove `device.sctpCapabilities` getter from mediasoup-client because anyway we are making up those values!\n - Also must update the website documentation.\n\n- When we invoke `close()` on a `DataProducer/Consumer` in server, we must end calling `sctpAssociation->ResetStream([streamId])` so it sends `ReConfig` to peer.\n\n- In `transport.dump()` (maybe also in `getStats()`) we must properly obtain `OS` and `MIS` according to the number of SCTP streams negotiated via INIT + INIT_ACK. And if SCTP is not yet established, then... not sure.\n - In `Association::FillBuffer()` we should not pass `this->sctpOptions.negotiatedMaxOutboundStreams/negotiatedMaxInboundStreams` but the current values.\n\n- We need to pass `isDataChannel` to `SCTP::Association` constructor as we do in former `SctpAssociation`. Also use it in `Association::FillBuffer()`.\n - Well, let's see.

The standard equivalent is `std::move_only_function`, introduced in C++23.\n\n If you use C++23:\n\n ```cpp\n std::vector> deferredActions;\n ```\n\n In C++20 there is no `std::move_only_function` (that is C++23). The problem is that `absl::AnyInvocable` accepts move-only callables, while `std::function` requires them to be copyable.\n\n This is relevant because in dcsctp the lambda captures `data = std::move(data)`, and `UserData` has its copy constructor deleted, so the resulting lambda is not copyable and `std::function` will reject it.\n\n The solution for C++20 is to move the `UserData` into a `shared_ptr` so that the lambda becomes copyable:\n\n ```cpp\n std::vector> deferredActions;\n ```\n\n And when adding the action, instead of:\n\n ```cpp\n // dcsctp - It works because AnyInvocable accepts move-only callables\n deferred_actions.push_back(\n [this, tsn, data = std::move(data)]() mutable {\n queued_bytes_ -= data.size();\n Add(tsn, std::move(data));\n });\n ```\n\n In your code:\n\n ```cpp\n // C++20 - UserData is not copyable, so it is wrapped in shared_ptr\n auto sharedData = std::make_shared(std::move(data));\n\n this->deferredResetStreams->deferredActions.push_back(\n [this, tsn, sharedData]() mutable\n {\n this->queuedBytes -= sharedData->GetPayloadLength();\n this->Add(tsn, std::move(*sharedData));\n });\n ```\n" }, { "path": "worker/include/RTC/SCTP/association/Association.hpp", "content": "#ifndef MS_RTC_SCTP_ASSOCIATION_HPP\n#define MS_RTC_SCTP_ASSOCIATION_HPP\n\n#include \"common.hpp\"\n#include \"SharedInterface.hpp\"\n#include \"RTC/SCTP/association/AssociationListenerDeferrer.hpp\"\n#include \"RTC/SCTP/association/NegotiatedCapabilities.hpp\"\n#include \"RTC/SCTP/association/PacketSender.hpp\"\n#include \"RTC/SCTP/association/StateCookie.hpp\"\n#include \"RTC/SCTP/association/TransmissionControlBlock.hpp\"\n#include \"RTC/SCTP/packet/Chunk.hpp\"\n#include \"RTC/SCTP/packet/Packet.hpp\"\n#include \"RTC/SCTP/packet/chunks/AbortAssociationChunk.hpp\"\n#include \"RTC/SCTP/packet/chunks/AnyDataChunk.hpp\"\n#include \"RTC/SCTP/packet/chunks/AnyForwardTsnChunk.hpp\"\n#include \"RTC/SCTP/packet/chunks/AnyInitChunk.hpp\"\n#include \"RTC/SCTP/packet/chunks/CookieAckChunk.hpp\"\n#include \"RTC/SCTP/packet/chunks/CookieEchoChunk.hpp\"\n#include \"RTC/SCTP/packet/chunks/DataChunk.hpp\"\n#include \"RTC/SCTP/packet/chunks/ForwardTsnChunk.hpp\"\n#include \"RTC/SCTP/packet/chunks/HeartbeatAckChunk.hpp\"\n#include \"RTC/SCTP/packet/chunks/HeartbeatRequestChunk.hpp\"\n#include \"RTC/SCTP/packet/chunks/IDataChunk.hpp\"\n#include \"RTC/SCTP/packet/chunks/IForwardTsnChunk.hpp\"\n#include \"RTC/SCTP/packet/chunks/InitAckChunk.hpp\"\n#include \"RTC/SCTP/packet/chunks/InitChunk.hpp\"\n#include \"RTC/SCTP/packet/chunks/OperationErrorChunk.hpp\"\n#include \"RTC/SCTP/packet/chunks/ReConfigChunk.hpp\"\n#include \"RTC/SCTP/packet/chunks/SackChunk.hpp\"\n#include \"RTC/SCTP/packet/chunks/ShutdownAckChunk.hpp\"\n#include \"RTC/SCTP/packet/chunks/ShutdownChunk.hpp\"\n#include \"RTC/SCTP/packet/chunks/ShutdownCompleteChunk.hpp\"\n#include \"RTC/SCTP/packet/chunks/UnknownChunk.hpp\"\n#include \"RTC/SCTP/public/AssociationInterface.hpp\"\n#include \"RTC/SCTP/public/AssociationListenerInterface.hpp\"\n#include \"RTC/SCTP/public/AssociationMetrics.hpp\"\n#include \"RTC/SCTP/public/Message.hpp\"\n#include \"RTC/SCTP/public/SctpOptions.hpp\"\n#include \"RTC/SCTP/public/SctpTypes.hpp\"\n#include \"RTC/SCTP/tx/RoundRobinSendQueue.hpp\"\n#include \"handles/BackoffTimerHandleInterface.hpp\"\n#include \n#include \n#include \n#include \n\nnamespace RTC\n{\n\tnamespace SCTP\n\t{\n\t\t/**\n\t\t * This is the implementation of the AssociationInterface.\n\t\t */\n\t\tclass Association : public AssociationInterface,\n\t\t public PacketSender::Listener,\n\t\t public BackoffTimerHandleInterface::Listener\n\t\t{\n\t\tpublic:\n\t\t\t/**\n\t\t\t * Internal SCTP association state.
