Our VobSub demuxer does not set the duration (it is encoded as part of the payload). So our muxer uses SimpleBlocks (because duration == 0 actually says "play this until the next packet arrives", which coincides with the semantics for SimpleBlocks). mkvmerge reads the duration from the payload. Is there a proper spec for the VobSub format somewhere? - Andreas _______________________________________________ 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".
