<p class="MsoNormal" style="text-align:left;direction:ltr;unicode-bidi:embed">Hello there,<o:p></o:p></p>
<p class="MsoNormal" style="text-align:left;direction:ltr;unicode-bidi:embed">I’ve been working on your library for a while now, in order to implement a RTSP server, streaming live audio and video.<o:p></o:p></p>
<p class="MsoNormal" style="text-align:left;direction:ltr;unicode-bidi:embed">The audio and video packets are received via TCP from another service, each type of packet (audio\video) to another socket.<o:p></o:p></p>
<p class="MsoNormal" style="text-align:left;direction:ltr;unicode-bidi:embed">What I did was creating a new sub-classes of MediaSubsession, one for PCM audio and one for H264 video, and for each one created a new framed source, similar to ByteStreamFileSource,
where in their doReadFromFile() I call recv() to the relevant socket instead of fread().<o:p></o:p></p>
<p class="MsoNormal" style="text-align:left;direction:ltr;unicode-bidi:embed">In my main, I just open the TCP sockets, create an RTSP server and add the two subsessions to it.<o:p></o:p></p>
<p class="MsoNormal" style="text-align:left;direction:ltr;unicode-bidi:embed"><o:p> </o:p></p>
<p class="MsoNormal" style="text-align:left;direction:ltr;unicode-bidi:embed">It works fine when I play video alone, or audio alone, but when I combine them the video usually stuck after a short while (~30 seconds) and the audio keeps playing ok.<o:p></o:p></p>
<p class="MsoNormal" style="text-align:left;direction:ltr;unicode-bidi:embed">In addition, during the time both of them played ok, they are not synched.<o:p></o:p></p>
<p class="MsoNormal" style="text-align:left;direction:ltr;unicode-bidi:embed"><o:p> </o:p></p>
<p class="MsoNormal" style="text-align:left;direction:ltr;unicode-bidi:embed">What am I doing wrong? I’ve read a lot about it and it seems my presentation times are not ok, but how can I calculate them properly?<o:p></o:p></p>
<p class="MsoNormal" style="text-align:left;direction:ltr;unicode-bidi:embed">Please advise, I’ve been working on this forever, and I’m sure it’ll be useful for others as well.<o:p></o:p></p>
