Member Function Documentation

virtual BOOL OpalRawMediaStream::Close (    )  [virtual]

Close the media stream. Closes the associated PChannel. Reimplemented from OpalMediaStream.

PChannel* OpalRawMediaStream::GetChannel (    )  [inline]

Return the associated PChannel

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

Read raw media data from the source media stream. The default behaviour reads from the PChannel object. Parameters: data  Data buffer to read to size  Size of buffer length  Length of data actually read Reimplemented from OpalMediaStream.

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

Write raw media data to the sink media stream. The default behaviour writes to the PChannel object. Parameters: data  Data to write length  Length of data to read. written  Length of data actually written Reimplemented from OpalMediaStream.
