if (pkt->dts != AV_NOPTS_VALUE && pkt->pts != AV_NOPTS_VALUE && pkt->pts <
"pts (%s) < dts (%s) in stream %d\n",
May I know why we need DTS <= PTS. I understand a frame need to be decoded
before it can be shown.
Say we has packets in [DTS, PTS]: [10, 0], [11, 2], [12, 3]
If decoding and display reference different clocks, DTS and PTS can be
totally decoupled and above is a valid sequence packets.
If DTS and PTS reference a same clock which means first packet needed to be
decoded at starttime + 10 but display at starttime + 0, of couse it's
invalid. So ffmpeg interprets DTS, PTS this way?
