</div><div apple-content-edited="true">I’d imagine at launch priming the rx pipeline with the frame size/rate it expects to receive from the other end, which will hopefully facilitate showing some kind of display until the actual video arrives. Just to consider a simple case, where these are hard-coded, are you able to point me at the appropriate API bits to accomplish that?</div><div apple-content-edited="true"><br></div><div apple-content-edited="true">Cheers!</div>

You use out of band signaling, something like SIP or RTSP. It really depends on your application - what you are trying to do, single system to many? One to one? Endpoints registered to a server? How do you know the addresses and ports and protocols? The sender could include the sprop_parameters in that communication.<br>
