The online documentation is available in the main [website](https://ffmpeg.org) and in the [wiki](https://trac.ffmpeg.org). ### Examples Coding examples are available in the **doc/examples** directory. ## License FFmpeg codebase is mainly LGPL-licensed with optional components licensed under GPL. Please refer to the LICENSE file for detailed information. ## Contributing Patches should be submitted to the ffmpeg-devel mailing list using `git format-patch` or `git send-email`. Github pull requests should be avoided because they are not part of our review process. Few developers follow pull requests so they will likely be ignored.
