The data reading from the UDP socket contains audio and video data. Now I want to relay the RTSP consists of an audio and a video subsession.The RTSP sends audio and video data to the diffrent port,But the testRelay program can read data only from one port.What can I to do to relay the audio and video that coming from two ports.</div></div></blockquote><div><br></div></div>It's easy. Simply model your application on the existing "testRelay" code, but duplicate the code that creates source and sink objects, and calls "startPlaying()". I.e.,<div>- Create another "groupsock" object: "inputGroupsock2"</div><div>- From this, create another "FramedSource*": "source2"</div><div>- Create another "groupsock" object: "outputGroupsock2"</div><div>- From this, create another "MediaSink*": "sink2"</div><div>- Then call</div><div><span class="Apple-tab-span" style="white-space:pre"> </span>sink2->startPlaying(*source2, NULL, NULL);</div><div>This call can be before or after the original</div><div><span class="Apple-tab-span" style="white-space:pre"> </span>sink->startPlaying(*source, NULL, NULL);</div><div>but both must occur before the call to</div><div><span class="Apple-tab-span" style="white-space:pre"> </span>env->taskScheduler().doEventLoop();</div><br><br><div apple-content-edited="true">
