Detailed Description

RTP Sender.

This class implements an RTP sender based on TimedThread.

Author:: Thomas Dreibholz

Version:: 1.0

Constructor & Destructor Documentation

RTPSender::RTPSender ( )

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

See also:: init

RTPSender::RTPSender	(	const InternetFlow &	flow,
		const card32	ssrc,
		EncoderInterface *	encoder,
		Socket *	senderSocket,
		const card32	controlPPID,
		const card32	dataPPID,
		const cardinal	maxPacketSize = `1500`,
		QoSManagerInterface *	qosManager = `NULL`
	)

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

Parameters:

flow	Flow to remote side.
ssrc	Sender's SSRC (see RFC 1889).
encoder	Encoder to get packets to send from.
senderSocket	Socket to write packets to.
controlPPID	PPID for SCTP control transport.
dataPPID	PPID for SCTP data transport.
maxPacketSize	Maximum packet size.
qosManager	QoS manager.

RTPSender::~RTPSender ( )

Destructor.

Member Function Documentation

card64 RTPSender::getBytesSent ( ) [inline]

Get number of bytes sent.

Returns:: Bytes sent.

cardinal RTPSender::getMaxPacketSize ( ) const [inline]

Get maximum packet size.

Returns:: Maximum packet size.

card64 RTPSender::getPacketsSent ( ) [inline]

Get number of packets sent.

Returns:: Packets sent.

AbstractQoSDescription * RTPSender::getQoSDescription ( const card64 offset ) [virtual]

Implementation of ManagedStreamInterface's getQoSDescription().

See also:: ManagedStreamInterface::getQoSDescription

Implements ManagedStreamInterface.

void RTPSender::init	(	const InternetFlow &	flow,
		const card32	ssrc,
		EncoderInterface *	encoder,
		Socket *	senderSocket,
		const card32	controlPPID,
		const card32	dataPPID,
		const cardinal	maxPacketSize = `1500`,
		QoSManagerInterface *	qosManager = `NULL`
	)

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

Parameters:

flow	Flow to remote side.
ssrc	Sender's SSRC (see RFC 1889).
encoder	Encoder to get packets to send from.
senderSocket	Socket to write packets to.
controlPPID	PPID for SCTP control transport.
dataPPID	PPID for SCTP data transport.
maxPacketSize	Maximum packet size.
qosManager	QoS manager.

void RTPSender::lock ( ) [virtual]

Implementation of ManagedStreamInterface's lock().

See also:: ManagedStreamInterface::lock

Implements ManagedStreamInterface.

bool RTPSender::paused ( ) const [inline]

Check, if transmission is paused.

Returns:: true, if paused; false otherwise.

void RTPSender::resetBytesSent ( ) [inline]

Reset number of bytes sent.

void RTPSender::resetPacketsSent ( ) [inline]

Reset number of packets sent.

cardinal RTPSender::setMaxPacketSize ( const cardinal size ) [inline]

Set maximum packet size.

Parameters:

size	Maximum packet size.

Returns:: Maximum packet size set.

void RTPSender::setPause ( const bool on ) [inline]

Set pause on or off.

Parameters:

on	true to set pause on; false to set pause off.

void RTPSender::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.

bool RTPSender::transmissionErrorDetected ( ) [inline]

Check, if transmission error has been detected (e.g. destination rejects packets, no route etc.). Note: The transmission error attribute will be resetted to false by calling this method.

void RTPSender::unlock ( ) [virtual]

Implementation of ManagedStreamInterface's unlock().
