This page describes how to create a receive source.
The RRtpReceiveSource
class represents the stream of data on a single SSRC (synchronised source) and delivers the RTP packets and RTCP information in the order they arrive.
RRtpSession
allows you to create a new receive stream. NewReceiveSourceLC()
and NewReceiveSourceL()
create a new receive stream and return a handle to an RRtpReceiveSource
.
RRtpReceivePacket
is derived from RRtpPacket
and provides a handle to a received RTP packet. To access the packet information, use the functions listed in Preparing the packet.
RRtpReceiveSource
provides the following functionality:
IsOpen
returns ETrue
if the stream is open.
GetByeReason
: Retrieves the reason for terminating the session
GetLastApp
: Retrieves the parameters from the last APP packet. You must specify the application name, application data, and sub-type of the APP packet.
Packet
: Gets the packet that has just arrived, or a closed packet if there is not one.
GetSDES
: Gets the data associated with the SDES (Source Description) item such as CNAME, NAME and so on.
SSRC
: Gets the source of stream of the RTP packets.
Close
: Closes the receive stream and releases all its resources.
To register for events from a stream, refer to the section Registering for and handling events.
Note: Before receiving an RTP packet you must set the bandwidth for the RTP session. The following code snippet shows how to set the bandwidth for an RTP session.
