Detailed Description

RTCP Sender.

This class implements an RTCP sender based on TimedThread.

Author:: Thomas Dreibholz

Version:: 1.0

Constructor & Destructor Documentation

Coral::RTCPSender::RTCPSender ( )

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

See also:: init

Coral::RTCPSender::RTCPSender	(	const card32	ssrc,
		Socket *	senderSocket,
		RTPReceiver *	receiver,
		const card64	bandwidth
	)

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

Parameters:

ssrc	SSRC.
senderSocket	Socket to write data to.
receiver	RTPReceiver for reports to send.
bandwidth	RTCP Bandwidth (see RFC 1889).

Coral::RTCPSender::~RTCPSender ( )

Destructor.

Member Function Documentation

bool Coral::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 Coral::RTCPSender::computeTransmissionInterval ( ) [private]

void Coral::RTCPSender::init	(	const card32	ssrc,
		Socket *	senderSocket,
		RTPReceiver *	receiver,
		const card64	bandwidth
	)

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

Parameters:

ssrc	SSRC.
senderSocket	Socket to write data to.
receiver	RTPReceiver for reports to send.
bandwidth	RTCP Bandwidth (see RFC 1889).

void Coral::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 Coral::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 Coral::RTCPSender::sendBye ( )

Send RTCP BYE message.

Returns:: Bytes sent.

integer Coral::RTCPSender::sendReport ( )

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

Returns:: Bytes sent.

integer Coral::RTCPSender::sendSDES ( )

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

Returns:: Bytes sent.

void Coral::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 Coral::TimedThread.
