Detailed Description

This class describes a media stream, which is an interface to the opal classes for generating encoded media data

Member Function Documentation

virtual void OpalIAX2MediaStream::InternalClose ( )

inlineprotectedvirtual

Close any internal components of the stream. This should be used in preference to overriding the Close() function as it is guaranteed to be called exactly once and avoids race conditions in the shut down sequence of a media stream.

Implements OpalMediaStream.

virtual PBoolean OpalIAX2MediaStream::IsSynchronous ( ) const

virtual

Indicate if the media stream is synchronous. false if this stream is from the network.

Returns: true if this stream is from a sound card.

Implements OpalMediaStream.

virtual PBoolean OpalIAX2MediaStream::ReadPacket ( RTP_DataFrame & packet )

virtual

Goes to the IAX2Connection class, and removes a packet from the connection. The connection class turned the media packet into a RTP_DataFrame class, and jitter buffered it.

Returns: true on successful read of a packet, false on faulty read.

Parameters

packet Data buffer to read to

Reimplemented from OpalMediaStream.

virtual PBoolean OpalIAX2MediaStream::WriteData	(	const BYTE *	data,
		PINDEX	length,
		PINDEX &	written
	)

virtual

Write raw media data to the sink media stream. The default behaviour writes to the OpalLine object.

Parameters

data	Data to write
length	Length of data to write.
written	Length of data actually written

Reimplemented from OpalMediaStream.

IAX2Connection& OpalIAX2MediaStream::connection

protected

The connection is the source/sink of our data packets

PBYTEArray OpalIAX2MediaStream::pendingData

protected

There was unused data from an incoming ethernet frame. The unused data is stored here.
