Constructor & Destructor Documentation

RTPQueueBase::RTPQueueBase (uint32 * ssrc = NULL) [protected]

Parameters

ssrc If not null, the local SSRC identifier for this session.

virtual RTPQueueBase::~RTPQueueBase () [inline], [protected], [virtual]

Member Function Documentation

virtual size_t RTPQueueBase::dispatchBYE (const std::string &) [inline], [protected], [virtual]

A plugin point for posting of BYE messages.

Parameters

- reason to leave the RTP session.

Returns

number of octets sent.

Reimplemented in QueueRTCPManager, TRTPSessionBase< RTPDataChannel, RTCPChannel, ServiceQueue >, TRTPSessionBase< DualRTPUDPIPv4Channel, DualRTPUDPIPv4Channel, AVPQueue >, and SingleThreadRTPSession< RTPDataChannel, RTCPChannel, ServiceQueue >.

PayloadType RTPQueueBase::getCurrentPayloadType () const [inline]

uint32 RTPQueueBase::getCurrentRTPClockRate () const [inline]

Get the clock rate in RTP clock units (for instance, 8000 units per second for PCMU, or 90000 units per second for MP2T). This value depends on what payload format has been selected using setPayloadFormat().

Returns

clock rate in RTP clock units.

Examples
ccrtptest.cpp, rtphello.cpp, and rtpsend.cpp.

timeval RTPQueueBase::getInitialTime () const [inline]

uint32 RTPQueueBase::getLocalSSRC () const [inline]

Examples
rtphello.cpp, rtplisten.cpp, and rtpsend.cpp.

uint32 RTPQueueBase::getLocalSSRCNetwork () const [inline], [protected]

virtual void RTPQueueBase::renewLocalSSRC () [inline], [protected], [virtual]

Reimplemented in RTPDataQueue, and IncomingDataQueue.

void RTPQueueBase::setLocalSSRC (uint32 ssrc) [inline], [protected]

bool RTPQueueBase::setPayloadFormat (const PayloadFormat & pf) [inline]

Set the payload format in use, for timing and payload type identification purposes.

Parameters

pf payload format to use from now on.

Returns

whether the payload format has been successfully set.

Examples
audiorx.cpp, audiotx.cpp, ccrtptest.cpp, rtpduphello.cpp, rtphello.cpp, rtplisten.cpp, and rtpsend.cpp.
