Member Function Documentation

virtual PBoolean OpalAudioMediaStream::SetDataSize

(

PINDEX

dataSize

)

[virtual]

Set the data size in bytes that is expected to be used. Some media streams can make use of this information to perform optimisations.

The defafault simply sets teh member variable defaultDataSize.

Parameters:

dataSize

New data size

Reimplemented from OpalMediaStream.

virtual PBoolean OpalAudioMediaStream::IsSynchronous

(

)

const [virtual]

Indicate if the media stream is synchronous. Returns true for LID streams.

Implements OpalMediaStream.
