Member Function Documentation

virtual BOOL OpalNullMediaStream::IsSynchronous (    )  [virtual]

Indicate if the media stream is synchronous. Returns FALSE. Implements OpalMediaStream.

virtual BOOL OpalNullMediaStream::ReadData (  BYTE *    data, PINDEX    size, PINDEX &    length )  [virtual]

Read raw media data from the source media stream. The default behaviour does nothing and returns FALSE. Parameters: data  Data buffer to read to size  Size of buffer length  Length of data actually read Reimplemented from OpalMediaStream.

virtual BOOL OpalNullMediaStream::RequiresPatchThread (    )  [virtual]

Indicate if the media stream requires a OpalMediaPatch thread. The default behaviour returns FALSE. Reimplemented from OpalMediaStream.

virtual BOOL OpalNullMediaStream::WriteData (  const BYTE *    data, PINDEX    length, PINDEX &    written )  [virtual]

Write raw media data to the sink media stream. The default behaviour does nothing and returns FALSE. Parameters: data  Data to write length  Length of data to read. written  Length of data actually written Reimplemented from OpalMediaStream.
