Member Function Documentation

virtual PBoolean OpalH224MediaStream::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 void OpalH224MediaStream::OnStartMediaPatch ( )

virtual

Callback that is called on the source stream once the media patch has started. The default behaviour calls OpalConnection::OnMediaPatchStart()

Reimplemented from OpalMediaStream.

virtual PBoolean OpalH224MediaStream::ReadPacket ( RTP_DataFrame & packet )

virtual

Read an RTP frame of data from the source media stream. The default behaviour simply calls ReadData() on the data portion of the RTP_DataFrame and sets the frames timestamp and marker from the internal member variables of the media stream class.

Reimplemented from OpalMediaStream.

virtual PBoolean OpalH224MediaStream::RequiresPatchThread ( ) const

inlinevirtual

Reimplemented from OpalMediaStream.

References OpalMediaStream::IsSink().

virtual PBoolean OpalH224MediaStream::WritePacket ( RTP_DataFrame & packet )

virtual

Write an RTP frame of data to the sink media stream. The default behaviour simply calls WriteData() on the data portion of the RTP_DataFrame and and sets the internal timestamp and marker from the member variables of the media stream class.

Reimplemented from OpalMediaStream.
