ffmpeg -h muxer=matroska This reveals a bit more options than outlined on the url you mentioned.
Sorry, I have already tried that but I forgot to write it here. If you see the matroska.org page there is a ton of flags or values a MKV can carry... But ffmpeg does not show this in the help text how to control this by syntax options. So maybe ffmpeg is not ready for meeting these specs or its just hidden until the spec is finished (v4)? br Chris _______________________________________________ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".
