Extends an RTP data i/o queue adding management of RTCP functions:
Provide feedback on the quality of the data distribution.

Control the sending rate of RTCP packets
Convey minimal control information about the participants
This class implements generic RTCP behaviour (as specified in RFC 1889/draft-ietf-avt-rtp-new) and may be specialized for specific profiles (see AVPQueue) or particular RTCP extensions.

Appy collision and loop detection and correction algorithm when receiving RTCP packets. Follows section 8.2 in draft-ietf-avp-rtp-new.
|
|
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:
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.
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.
|
|
Get the most recent sender report received from a synchronization source.
|
|
|
|
|
|
Get the total number of RTCP packets sent until now.
|
|
Plug-in for handling of APP (application specific) RTCP packets.
|
|
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.
|
|
|
|
Plug-in for handling of SDES chunks.
|
|
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.
|
|
|
|
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.
|
|
Set how much time the stack will wait before deleting a synchronization source that has sent an RTCP BYE packet.
|
|
Manually set the minimum interval for sending RTP compound packets.
|
|
|
|
Specify the fraction of the total control bandwith to be dedicated to senders reports.
1 - fraction will be dedicated to receivers reports.
