Hi, <div><br></div><div>I have created a subclass of MediaSink which process the received data. I am using this instead of FileSink. </div><div><br></div><div>I am able to see MultiFramedRTPSource::doGetNextFrame1() getting called before I start playing streams. It also calls my afterGettingFrame() and continuePlaying() function. All this works fine.</div>
<div><br></div><div>Problem starts when it get into doEventLoop(). I see MultiFramedRTPSource::doGetNextFrame1() getting called but it does not call the afterGetting(this); (at line number 195). </div><div><br></div><div>
I investigated and found that packet->rtpMarkerBit(); in MPEG4ESVideoRTPSource::processSpecialHeader() always returns 0 because of which it does not get into the loop.</div><div><br></div><div>Could you please help me understand what should be done to make this work.</div>

I believe it is possible to have the streams in buffer but not clear how? I went through RTPSource class which has a function pointer setAuxilliaryReadHandler(). As I understand this is for registering a handler for processing RTP read.<br>

"setAuxilliaryReadHandler()" is a hack that should not be used. I don't think anyone uses it anymore, and it will likely be removed from a future release of the code. In any case, it provides access to raw RTP packets (i.e., including RTP headers) - and that's *not* what you want.<div class="im">

After long discussion and research we had decided to make use of live555 stack as it is widely used (and tested). I have gone through the openRTSP.cpp which actually saves all the streams to a file. I do not want to record streams in a file and read from the file as this will have latency.<br>

OK, then your solution is straightforward. You need to write your own subclass of "MediaSink" that does whatever you want to do with the incoming data, and use that *instead of* "FileSink".<br>
<br>
(Or, if your incoming stream is video-only (or audio-only), then you could use the "-v" (or "-a") option to "openRTSP", and pipe it into a separate application (that reads from stdin) that processes it.)<br>
