|
|
|
Add csrc as the CSRC identifier of a new contributor. This method adds the CSRC identifier to a list of contributors that will be inserted in every packet enqueued from now on. |
|
|
|
|
|
This function is used by the service thread to process the next outgoing packet pending in the sending queue.
|
|
This is used to write the RTP data packet to one or more destinations. It is used by both sendImmediate and by dispatchDataPacket.

|
Get wheter the mark bit will be set in the next packet.
|
|
Get an output queue CryptoContext identified by SSRC.
|
|
This computes the timeout period for scheduling transmission of the next packet at the "head" of the send buffer. If no packets are waiting, a default timeout is used. This actually forms the "isPending()" timeout of the rtp receiver in the service thread.
|
|
Get the total number of octets (payload only) sent so far.
|
|
Get the total number of packets sent so far.
|
|
Get the sequence number of the next outgoing packet.
|
|
Determine if outgoing packets are waiting to send.
|
|
|
|
This is used to create a data packet in the send queue. Sometimes a "NULL" or empty packet will be used instead, and these are known as "silent" packets. "Silent" packets are used simply to "push" the scheduler along more accurately by giving the appearence that a next packet is waiting to be sent and to provide a valid timestamp for that packet.
|
|
Remove CSRC from the list of contributors.
|
|
Remove output queue CryptoContext. The endQueue method (provided by RTPQueue) also deletes all registered CryptoContexts.

Reimplemented in RTPDuplex. |
|
Set the "expired" timer for expiring packets pending in the send queue which have gone unsent and are already "too late" to be sent now.
|
|
|
|
Set marker bit for the packet in which the next data provided will be send. When transmitting audio, should be set for the first packet of a talk spurt. When transmitting video, should be set for the last packet for a video frame.

For thoses cases in which the application requires a method to set the sequence number for the outgoing stream (such as for implementing the RTSP PLAY command).
|
|
Set ouput queue CryptoContext. The endQueue method (provided by RTPQueue) deletes all registered CryptoContexts.
|
|
Set padding. All outgoing packets will be transparently padded to a multiple of paddinglen.
|
|
Set partial data for an already queued packet. This is often used for multichannel data.
|
|
Set the default scheduling timeout to use when no data packets are waiting to be sent.
