packet streaming. It uses <codeph>CRtpFileSender</codeph> to send RTP packets

and <codeph>CRtpFileStreamer</codeph> to receive RTP packets. The example

opens an RTP session using the pre-connected socket and initialises new send

and receive sources on the RTP session. It registers the callback functions

when an RTP packet is successfully sent by a send source or received by a

receive source, to receive notifications whenever an RTP packet is sent or

received. </p> <p>The <filepath>RTPExample</filepath> example code provides

the following functionality: </p> </section>
