I did some digging and found the error is coming from this code in flvenv.c line 921.
<div><br>
</div>
<div> if (pkt->dts < -flv->delay) {</div>
<div> av_log(s, AV_LOG_WARNING,</div>
<div> "Packets are not in the proper order with respect to DTS\n");</div>
<div> return AVERROR(EINVAL);</div>
<div><br>
</div>
<div>flv is a pointer to FLVContext from AVFormatContext->priv_data.<br>
</div>
<div><br>
</div>
<div>Looks like the avformat_write_header()/avformat_init_output uses the state of the muxer at the last run even if the AVFormatContext has been freed and reallocated.</div>
So how do I get the FLVContext to be initlized as if a fresh run. Or how do I free the old FLVContext so when avformat_write_header() initlizes the priv_data it is fresh.<br>
