The stream has a stream-ID of 0xBD (stream type private??). There are several packets (e.g. 5) of this type spread throughout the file, each with it own PTS. </p><p class="ecxp1" style="line-height: 21px; margin-bottom: 1.35em; color: rgb(68, 68, 68); font-size: 15px;"><br></p><p class="ecxp1" style="margin-bottom: 1.35em;">
<p class="p1" style="color: rgb(68, 68, 68); font-size: 15px; line-height: 21px;">"avformat_open_input()" does not identify (unknown type) this third stream and "avformat_find_stream_info()" guesses it is an audio mp3 stream. Since I know the stream is data, I have tried overriding the stream type to AVMEDIA_TYPE_NB, AVMEDIA_TYPE_DATA, and AVMEDIA_TYPE_ATTACHMENT. I do not need a decoder for this stream since I can see the data in the packets returned from "av_read_frame()" and I can decode the data myself, however there is a problem that appears regardless my stream type overrides:</p>

I would really like each of the packets in the file to return from "av_read_frame()" individually, each with its own PTS. </p><p class="p1" style="color: rgb(68, 68, 68); font-size: 15px; line-height: 21px;"><br></p><p class="p1"><font color="#444444"><span style="font-size: 15px; line-height: 21px;">Does anyone know why av_read_frame() might be concatenating data packets and consolidating them into a single packet?</span></font></p><p class="p1"><font color="#444444"><span style="font-size: 15px; line-height: 21px;"><br></span></font></p><p class="p1"><font color="#444444"><span style="font-size: 15px; line-height: 21px;">Thank You,</span></font></p><p class="p1"><font color="#444444"><span style="font-size: 15px; line-height: 21px;">This has been a hard one for me.</span></font></p>
