Hi guys,
In av_write_frame()->compute_muxer_pkt_fields()
we have
if (pkt->dts != AV_NOPTS_VALUE && pkt->pts != AV_NOPTS_VALUE && pkt->pts <
pkt->dts) {
av_log(s, AV_LOG_ERROR,
"pts (%s) < dts (%s) in stream %d\n",
av_ts2str(pkt->pts), av_ts2str(pkt->dts),

These are invalid timestamps

I don't think this is correct, DTS

Just want to know why they are invalid, because packet.dts must be <=
packet.pts, right?
