Detailed Description

RTCP Sender.

This class implements an RTCP sender based on TimedThread.

Author:: Thomas Dreibholz

Version:: 1.0

Constructor & Destructor Documentation

RTCPSender::RTCPSender ( )

Default constructor. You have to initialize RTPSender by calling init(...) later!

See also:: init

RTCPSender::RTCPSender	(	const InternetFlow &	flow,
		const card32	ssrc,
		Socket *	senderSocket,
		RTPReceiver *	receiver,
		const card64	bandwidth,
		const card32	controlPPID
	)

Constructor for new RTCPSender. The new sender's thread has to be started by calling start()!

Parameters:

flow	Flow to remote side.
ssrc	SSRC.
senderSocket	Socket to write data to.
receiver	RTPReceiver for reports to send.
bandwidth	RTCP Bandwidth (see RFC 1889).
controlPPID	PPID for SCTP transport.

RTCPSender::~RTCPSender ( )

Destructor.

Member Function Documentation

bool RTCPSender::addSDESItem	(	const card8	type,
		const void *	data,
		const card8	length = `0`
	)

Add SDES item to SDES item list. If a SDES item with the same type already exists in the list, the new item replaces the old item.

Parameters:

type	SDES item type.
data	SDES item data.
length	SDES item data length.

Returns:: true, if item has been added; false, if not.

double RTCPSender::computeTransmissionInterval ( ) [private]

void RTCPSender::init	(	const InternetFlow &	flow,
		const card32	ssrc,
		Socket *	senderSocket,
		RTPReceiver *	receiver,
		const card64	bandwidth,
		const card32	controlPPID
	)

Initialize new RTCPSender. The new sender's thread has to be started by calling start()!

Parameters:

flow	Flow to remote side.
ssrc	SSRC.
senderSocket	Socket to write data to.
receiver	RTPReceiver for reports to send.
bandwidth	RTCP Bandwidth (see RFC 1889).
controlPPID	PPID for SCTP transport.

void RTCPSender::removeSDESItem ( const card8 type )

Remove SDES item from SDES item list.

Parameters:

type	SDES item type to be removed.

See also:: addSDESItem; sendSDES

integer RTCPSender::sendApp	(	const char *	name,
		const void *	data,
		const cardinal	dataLength
	)

Send RTCP APP message.

Parameters:

name	RTCP APP name.
data	RTCP APP data.
dataLength	RTCP APP data length.

Returns:: Bytes sent.

integer RTCPSender::sendBye ( )

Send RTCP BYE message.

Returns:: Bytes sent.

integer RTCPSender::sendReport ( )

Send RTCP receiver report from the SourceStateInfo given in the constructor.

Returns:: Bytes sent.

integer RTCPSender::sendSDES ( )

Send RTCP SDES message from the list given by addSDESItem().

Returns:: Bytes sent.

void RTCPSender::timerEvent ( ) [private, virtual]

The virtual timerEvent() method, which contains the timed thread's implementation. It has to be implemented by classes, which inherit TimedThread. This method is called regularly with the given interval.

Implements TimedThread.
