This class allows for jrtp to process packets without sending them out
anywhere.
The incoming messages are handed in to jrtp through the TransmissionParams
and can be retreived from jrtp through the normal polling mecanisms.
The outgoing RTP/RTCP packets are given to jrtp through the normal
session->SendPacket() and those packets are handed back out to the
client through a callback function (packet_ready_cb).
example usage : Allows for integration of RTP into gstreamer.
