How should I validate pts/dts after demuxing and then after decoding? For me it is significant to have valid pts all the time for days and possibly weeks of continuous streaming.
After demuxing I check: 1) dts <= pts 2) prev_packet_dts < next_packet_pts 3) I also discard packets with AV_NOPTS_VALUE and wait for packets with proper pts, because I don't know video duration at this case. * pts of packets can be not increasing because of I-P-B frames Is it all right? What about decoded AVFrames? 1) Should 'pts' be increasing all the time? 2) Why at some point 'pts' could lag behind 'dts'? 3) Why pict_type is a parameter of AVFrame? Should be at AVPacket, because AVPacket is a compressed frame, not the opposite?
