When the decoded frame is an I frame with pts and dts,  and there are b
frames in the input video sequence, the following lines will run in the
function compute_pkt_fields.

    if(delay==1 && pkt->dts == pkt->pts && pkt->dts != AV_NOPTS_VALUE &&
presentation_delayed){
        av_log(s, AV_LOG_DEBUG, "invalid dts/pts combination\n");
        pkt->dts= pkt->pts= AV_NOPTS_VALUE;
    }


it is obviously that it is not right.  temporally I can't upload the
corresponding video sequence because of the network problem. But it can just
be judged by reading the code.
