PTS-DTS shift is dependent on GopRefDist and NumRefFrame encoder initialization parameters in current h264 encoder implementation (although, in my opinion, the dependence on GopRefDist is superfluous). (with h264) I'm not focusing on them. Instead, packets from the stream might have what is called a decoding time stamp (DTS) and a presentation time stamp (PTS). I was using FFmpeg to inspect the stream and noticed I am getting duplicate pts/dts time stamps. ffprobe says 50fps but the pts/dts timestamps in the show_frames output work out to 25fps Unfortunately the only other PAFF files I have are from the same source and are encoded the same way.

I have tried setting tStart = min(PTS, DTS) and setting tEnd = max(PTS, DTS), and it is really jerky. The MIME-type/subtype pair of "video/MP2T", as specified in RFC 3551, must be used for byte streams that conform to this specification. When we receive h264 from liveMedia, we don't have an i_dts for the blocks. 1 high resolution mix.
