virtual PBoolean OpalIMMediaStream::IsSynchronous

(

)

const [inline, virtual]

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.

bool OpalIMMediaStream::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.

Reimplemented in OpalMSRPMediaStream.

virtual PBoolean OpalIMMediaStream::RequiresPatchThread

(

)

const [inline, virtual]

Reimplemented from OpalMediaStream.

Reimplemented in OpalMSRPMediaStream.

bool OpalIMMediaStream::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.

Reimplemented in OpalMSRPMediaStream.
