OpalUDPMediaStream::OpalUDPMediaStream	(	OpalConnection &	conn,
		const OpalMediaFormat &	mediaFormat,
		unsigned	sessionID,
		bool	isSource,
		OpalTransportUDP &	transport
	)

Construct a new media stream for channel.

Parameters

conn	Connection that owns the stream
mediaFormat	Media format for stream
sessionID	Session number for stream
isSource	Is a source stream
transport	UDP transport instance

OpalUDPMediaStream::~OpalUDPMediaStream ( )

Member Function Documentation

virtual PBoolean OpalUDPMediaStream::IsSynchronous ( ) const

virtual

Indicate if the media stream is synchronous. Returns false.

Implements OpalMediaStream.

virtual PBoolean OpalUDPMediaStream::ReadPacket ( RTP_DataFrame & packet )

virtual

Read an RTP frame of data from the source media stream. The new behaviour simply calls OpalTransportUDP::ReadPDU().

Reimplemented from OpalMediaStream.

virtual PBoolean OpalUDPMediaStream::WritePacket ( RTP_DataFrame & packet )

virtual

Write an RTP frame of data to the sink media stream. The new behaviour simply calls OpalTransportUDP::Write().

Reimplemented from OpalMediaStream.
