Description
FFmpeg does not recognize 'dav1' codec tag and rejects such streams with:
Could not find codec parameters for stream 0 (Video: none, 1 reference frame (dav1 / 0x31766164), none, 3840x2160 (0x0), 34009 kb/s): unknown codec
'dav1' tag is registered in the MPEG-4 Registration Authority: https://github.com/mp4ra/mp4ra.github.io/issues/101
There is already an open patch for this very issue: https://patchwork.ffmpeg.org/project/ffmpeg/patch/20230315185711.4800-1-jamrial@gmail.com/
but I didn't find any related ticket in the bug tracker.
