Possible to 'prime' pipeline with frame size/etc?

[Chuck Crisler]

Sure. 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.
