Flutter: Lack of Support for AV1 and VC-1 Codecs

[husen-hn]

Description The FFmpeg plugin for Flutter does not support the AV1 and VC-1 video codecs. This limits its usability in scenarios where these codecs are required.

Expected behavior The plugin should be able to decode and encode videos using the AV1 and VC-1 codecs.

Current behavior The plugin throws an error when attempting to use AV1 or VC-1 codecs.

Correct, we only have dav1d as a decoder, but no encoders.

libaom is technically there but you need to build your own ffmpeg-kit package since it is not included in the current ffmpeg-kit packages. We are evaluating supporting other AV1 encoders. The main problem is they don't support all platforms.
