 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);
