It *is* something that should be specifically marked in MP4, though, which does vhae proper facilities for this stuff. The problem is our API has no concept of RAPs other than "is an IDR". Proper way to write e.g. intra-refresh streams is: * Write the 'sdtp' box. * Write the 'sgpd' and 'sbgp' boxes with a 'roll' sample grouping type and roll_distance properly set. Annex I of the MP4 spec is quite clear how all types of recover and sync points should be written. - Derek _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-devel To unsubscribe, visit link above, or email ffmpeg-devel-requ...@ffmpeg.org with subject "unsubscribe".
