It prints the encoded gif directly to standard output when omitting the output filename.\n\n![demo](https://i.imgur.com/Hoi0fF7.gif)\n\n*I used **giph** to record a gif of **giph** recording a gif*.\n\n## Examples\n\n```bash\n$ giph -s -l -c 1,1,1,0.3 -b 5 -p -5 out.gif \n```\nSelect a window or area with slop. The selection rectangle is highlighted in a transparent blue color abd has a 5px border on the inside. \nAfter stopping the recording with either `ctrl+c`, by running `giph --stop` or by sending a `SIGINT` to the processgroup, the resulting gif is written to `out.gif`.\n\n\n```bash\n$ giph -g 100x200+0+0 -d 5 -t 10\n```\nRecords a 100x200 pixel rectangle in the top left corner of the screen. The recording starts after a 5 seconds countdown and will record for exactly 10 seconds. The resulting gif will be printed to standard output, which makes this able to be piped into other scripts like a file-upload to an image hosting service.\n\n\n```bash\n$ giph -f 30 -t 5 -s -a -m out.webm\n```\nRecords a 5 second video of the users selection at 30 fps. The recording also contains the users desktop audio and microphone. If the recording fails because the default audio source `0` is not the correct one, run `pacmd list-sources` to get the correct source `index` or `name` and pass it to the `-as` parameter instead of using `-a`. Example: `giph -f 30 -t 5 -s -as 1 -m out.webm` (using id) or `giph -f 30 -t 5 -s -as alsa_output.pci-0000_04_00.1.hdmi-stereo.monitor -m out.webm` (using name)\n\n```bash\n$ giph -s -t 10 --format webm | curl -F \"file=@-\" 0x0.st | xclip -selection clipboard\n```\n\nRecords a 10 second webm of the users selection, uploads the video to 0x0.st using curl and copies the returned url to the clipboard.\n\n## Installation\n\n### Arch\n\n```bash\n$ yay -S giph\n```\nOr install [giph-git](https://aur.archlinux.org/packages/giph-git/) to get the latest development version.\n\n### From source\n\nMake sure to install the following dependencies:\n\n - ffmpeg\n - xdotool\n\nOptionally, install the following dependencies:\n\n - slop (`--select`)\n - libnotify (`--notify`)\n - pgrep (`--stop`)\n\nClone the giph repository:\n\n```bash\n$ git clone https://github.com/phisch/giph.git\n```\n\nAnd finally install giph:\n\n```bash\n$ cd giph\n$ sudo make install\n```\n\n## Desktop Makers\n\n\"type=discord\"\n\nI am actively working on giph and other cool projects on the [Desktop Makers Discord](https://discord.gg/RqKTeA4uxW). It aims to be a community for communities of Linux desktop related projects.
