Description

This example code demonstrates RTP -packet streaming. It uses CRtpFileSender to send RTP packets -and CRtpFileStreamer 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.

-
Initialising void CRtpFileStreamer::ConstructL();

Opens an RTP session using the pre-connected socket and initialises new send -sources on the RTP session.

-
Sending an RTP packet void CRtpFileSender::RunL();

Sends the RTP packet. This does the following:

    -

  • gets a new RTP packet -to send from the send source

    • -

  • sets the RTP timestamp -of the RTP packet

    • -

  • reads a block of data -from the source file

    • -

  • creates an RTP packet -using the block of data

    • -

  • sends the RTP packet

    • -

  • closes the source file.

    • -

CRtpFileSender::PacketSent() is called to notify -that the RTP packet has been successfully sent.

-
Receiving an RTP packet void CRtpFileStreamer::NewSource();

When an RTP packet with a new receive source arrives, this callback function -is called, which registers the packet. This can be used for different types -of RTP packets such as APP, BYE, SDES, SR and RR.

void CRtpFileStreamer::PacketArrived();

Whenever an RTP packet arrives, this callback function is called. The -function retrieves the payload from the packet received and writes it to the -target file.
