setting up rtpbin from an SDP offer

[Daniel Pocock]

Is there an example of how to completely create an rtpbin, udpsink and
udpsrc from an SDP offer message body?

Is it necessary for each application developer to inspect the SDP and
create each of those elements with the port numbers or is there an
automated way to do that?

I notice that for webrtcbin it can work from the SDP alone and create
all the necessary udpsink/udpsrc
