dts are decode timestamps, that is for video thats when a packet enters an idealized decoder, pts is the timestamp when the video frame is presented for audio pts == dts generally as theres no reordering or delay in the ideallized decoder that is assumed what do they mean for SCTE-35 ? IIUC SCTE-35 can describe various timespans, how do these relate to dts/pts ? are the dts/pts entirely meaningless and just used for transport stream interleaving or do they somehow match the start of some timestamp? Are the timespans inside relative to the dts/pts or not? I think writing a few words about this would make it easier for applications to use this instead of just passing opaque SCTE-35 packets between libavformat and libavcodec > I'll be happy to add comments but I need a bit of assistance here. > _______________________________________________ > ffmpeg-devel mailing list > ffmpeg-devel@ffmpeg.org > http://ffmpeg.org/mailman/listinfo/ffmpeg-devel -- Michael GnuPG fingerprint: 9FF2128B147EF6730BADF133611EC787040B0FAB I have often repented speaking, but never of holding my tongue. -- Xenocrates
