It might be not be that difficult to add support for these tags. ffmpeg seems to be able to decode these tags just fine though - https://github.com/FFmpeg/FFmpeg/blob/master/libavformat/mov.c#L333 Best, Kieran. _______________________________________________ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".
