FFmpeg

Mastodon requires an installation of FFmpeg for video processing, and administrators must ensure a supported FFmpeg version is present and configured.

Versions of Mastodon are listed across the top of the matrix. Versions of each required component are listed along the left side.

Terminal

# Check running version
ffmpeg -version

If you do not see a major/minor version of it listed in the matrix, it is considered end of life. While it may continue to work, it may contain known issues including security vulnerabilities. Refer to endoflife.date for more information on determining if your version of FFmpeg is considered supported.

The official Mastodon container image since version 4.4 will always use the highest possible FFmpeg version for that release.

libvips

Mastodon requires an image processor, preferably libvips. Support for ImageMagick may be removed in a future release and administrators should plan to migrate now.

Mastodon may optionally utilize an installation of Elasticsearch or OpenSearch. Administrators may add either service to enable full-text search features.
