wrong pkt in range check in the ffplay

[chinshou]

the packet in range check does not check whether start time is equal to AV_NOPTS_VALUE. if ic->streams[pkt->stream_index]->start_time == AV_NOPTS_VALUE ,following code will not generate correct result.

pkt_in_play_range = duration == AV_NOPTS_VALUE

(pkt->pts - ic->streams[pkt->stream_index]->start_time) *
av_q2d(ic->streams[pkt->stream_index]->time_base) -
(double)(start_time != AV_NOPTS_VALUE ? start_time : 0) / 1000000
<= ((double)duration / 1000000);

Please either provide a failing sample (including failing command line including complete, uncut console output) or send a patch to ffmpeg-devel.
