This is where you would use the "testRelay" code as a guide. Your subclass's "createNewStreamSource()" virtual function can be quite simple - basically just creating a "groupsock" for your IP multicast address, and then creating a "BasicUDPSource" using that "groupsock" object.</div><br><br><div apple-content-edited="true">
