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.
