This action sets up and caches a specific FFmpeg version, providing the ffmpeg and ffprobe commands.

Builds are downloaded from the following sources:

• https://johnvansickle.com/ffmpeg/ Linux builds
• https://www.gyan.dev/ffmpeg/builds/ Windows builds
• https://evermeet.cx/ffmpeg/ MacOS builds

Version 3 of this action downloads binaries directly from the sources listed above instead of periodically updating GitHub releases. In turn this means it receives updates more frequently and supports git master builds and selecting a specific version.

By default the latest release version available for the platform is used. As upstream sources are not guaranteed to update at the same time, the action may at times install different versions of ffmpeg for different operating systems, unless a specific version is requested.

See action.yml.
