size_t dispatchBYE (const std::string &reason)

Appy collision and loop detection and correction algorithm when receiving RTCP packets.

Follows section 8.2 in draft-ietf-avp-rtp-new.

Parameters: sourceLink link to the source object.

is_new whether the source has been just recorded.

na RTCP packet network address.

tp RTCP packet source transport port.

Returns: whether the packet must not be discarded.

Process incoming RTCP packets pending in the control reception socket.

Build and send RTCP packets following timing rules (including the 'timer reconsideration' algorithm).

This method is used to send an RTCP BYE packet.

An RTCP BYE packet is sent when one of the the following circumstances occur:

•

when leaving the session

•

when we have detected that another synchronization source in the same session is using the same SSRC identifier as us.

Try to post a BYE message. It will send a BYE packet as long as at least one RTP or RTCP packet has been sent before. If the number of members in the session is more than 50, the algorithm described in section 6.3.7 of RFC 3550 is applied in order to avoid a flood of BYE messages.

Parameters: reason reason to specify in the BYE packet.

Reimplemented from RTPQueueBase.

Reimplemented in AVPQueue.

Get the number of data packets sent at the time the last SR was generated.

Ask for the info in the most recent receiver report about the local source received from the source given as parameter.

Parameters: srcFrom Source of the receiver info.

Returns: most recent receiver info received from src.

Return values: NULL when no receiver report has been received from the specified source.

Get the most recent sender report received from a synchronization source.

Parameters: src Synchronization source of the sender info.

Returns: Most recent sender info received from src.

Return values: NULL when no sender report has been received from the specified source.

Get the total number of RTCP packets sent until now.

Plug-in for handling of APP (application specific) RTCP packets.

Parameters: - Synchronization source of this packet.

- RTCP APP packet struct.

- Length of the app data packet, including ssrc. name and app. specific data.

Plug-in for processing (acquire information carried in) an incoming RTCP Receiver Report.

The default implementation in this class only processes the receiver report blocks about the local source.

Parameters: source Synchronization source this report comes from.

RR Receiver report structure

blocks Number of report blocks in the packet

Parameters: source Synchronization source of SDES RTCP packet.

pkt SDES RTCP packet received.

Plug-in for handling of SDES chunks.

Parameters: source Synchronization source of SDES chunk.

chunk SDES chunk structure.

len Length of chunk, in octets.

Returns: whether there was a CNAME.

Plug-in for processing (acquire information carried in) an incoming RTCP Sender Report.

The default implementation in this class only processes the sender information and the receiver report blocks about the local source.

Parameters: source Synchronization source this report comes from.

SR Sender report structure.

blocks Number of report blocks in the packet.

Reimplemented in AVPQueue.

This method sets the maximum end to end delay allowed.

If the processing delay plus the trip time for a packet is greater than the end to end delay, the packet is discarded, and the application cannot get it.

This is a way of setting an upper bound to the end to end delay, computed as the elapsed time between the packet timestamping at the sender side, and the picking of the packet at the receiver side.

Parameters: t maximum end to end delay allowed. A value of 0 implies there is no limit and is the default

Set how much time the stack will wait before deleting a synchronization source that has sent an RTCP BYE packet.

Parameters: delay delay in microseconds.

Note: The default delay is 1000000 microseconds

Parameters: n Number of members.

Specify the fraction of the total control bandwith to be dedicated to senders reports.

Parameters: fraction fraction of bandwidth, must be between 0 an 1.

This method sets the fraction of the global control bandwidth that will be dedicated to senders reports. Of course, 1 - fraction will be dedicated to receivers reports.
