Member Function Documentation

virtual PBoolean RTP_UDP::ReadData	(	RTP_DataFrame &	frame,
		PBoolean	loop
	)			[virtual]

Read a data frame from the RTP channel. Any control frames received are dispatched to callbacks and are not returned by this function. It will block until a data frame is available or an error occurs.

Implements RTP_Session.

virtual PBoolean RTP_UDP::Internal_ReadData	(	RTP_DataFrame &	frame,
		PBoolean	loop
	)			[virtual]

virtual PBoolean RTP_UDP::WriteData

(

RTP_DataFrame &

frame

)

[virtual]

Write a data frame to the RTP channel.

Implements RTP_Session.

virtual PBoolean RTP_UDP::Internal_WriteData

(

RTP_DataFrame &

frame

)

[virtual]

virtual PBoolean RTP_UDP::WriteOOBData	(	RTP_DataFrame &	frame,
		bool	setTimeStamp = true
	)			[virtual]

Write data frame to the RTP channel outside the normal stream of media Used for RFC2833 packets

Reimplemented from RTP_Session.

virtual PBoolean RTP_UDP::WriteControl

(

RTP_ControlFrame &

frame

)

[virtual]

Write a control frame from the RTP channel.

Implements RTP_Session.

virtual void RTP_UDP::Close

(

PBoolean

reading

)

[virtual]

Close down the RTP session.

Parameters:

reading

Closing the read side of the session

Implements RTP_Session.

virtual PString RTP_UDP::GetLocalHostName

(

)

[virtual]

Get the session description name.

Implements RTP_Session.

virtual PBoolean RTP_UDP::ModifyQOS

(

RTP_QOS *

rtpqos

)

[virtual]

Change the QoS settings

Reimplemented from RTP_Session.

virtual PBoolean RTP_UDP::Open	(	PIPSocket::Address	localAddress,
		WORD	portBase,
		WORD	portMax,
		BYTE	ipTypeOfService,
		PNatMethod *	natMethod = NULL,
		RTP_QOS *	rtpqos = NULL
	)			[virtual]

Open the UDP ports for the RTP session.

Parameters:

localAddress	Local interface to bind to
portBase	Base of ports to search
portMax	end of ports to search (inclusive)
ipTypeOfService	Type of Service byte
natMethod	NAT traversal method to use createing sockets
rtpqos	QOS spec (or NULL if no QoS)

virtual void RTP_UDP::Reopen

(

PBoolean

isReading

)

[virtual]

Reopens an existing session in the given direction.

Implements RTP_Session.

(

)

[inline, virtual]

Get data UDP socket of session.

virtual PUDPSocket& RTP_UDP::GetControlSocket

(

)

[inline, virtual]
