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.,
- Create another "groupsock" object: "inputGroupsock2"
- From this, create another "FramedSource*": "source2"
- Create another "groupsock" object: "outputGroupsock2"
- From this, create another "MediaSink*": "sink2"
- Then call
sink2->startPlaying(*source2, NULL, NULL);
This call can be before or after the original
sink->startPlaying(*source, NULL, NULL);
but both must occur before the call to
env->taskScheduler().doEventLoop();
