Member Function Documentation

PURL OpalMSRPMediaStream::GetRemoteURL ( ) const

inline

References OpalMSRPMediaSession::GetRemoteURL(), and m_msrpSession.

virtual void OpalMSRPMediaStream::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 OpalMSRPMediaStream::IsSynchronous ( ) const

inlinevirtual

Indicate if the media stream is synchronous. If this returns true then the media stream will block of the amount of time it takes to annunciate the data. For example if the media stream is over a sound card, and 480 bytes of data are to be written it will take 30 milliseconds to complete.

Implements OpalMediaStream.

virtual bool OpalMSRPMediaStream::Open ( )

virtual

Open the media stream using the media format.

The default behaviour simply sets the isOpen variable to true.

Reimplemented from OpalMediaStream.

OpalMSRPMediaStream::PDECLARE_NOTIFIER2	(	OpalMSRPManager	,
		OpalMSRPMediaStream	,
		OnReceiveMSRP	,
		OpalMSRPManager::IncomingMSRP &
	)

virtual PBoolean OpalMSRPMediaStream::ReadPacket ( RTP_DataFrame &  frame )

virtual

Read raw media data from the source media stream. The default behaviour reads from the PChannel object.

Reimplemented from OpalMediaStream.

virtual PBoolean OpalMSRPMediaStream::RequiresPatchThread ( ) const

inlinevirtual

Reimplemented from OpalMediaStream.

References OpalMediaStream::IsSink().

void OpalMSRPMediaStream::SetRemoteURL ( const PURL &  url )

inline

References m_msrpSession, and OpalMSRPMediaSession::SetRemoteURL().

virtual PBoolean OpalMSRPMediaStream::WritePacket ( RTP_DataFrame &  frame )

virtual

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

Reimplemented from OpalMediaStream.
