CMSPCallBase::CreateStreamObject method (mspcall.h)

The CreateStreamObject method is called by InternalCreateStream. The derived class should CreateInstance on its stream object, do an ATL _InternalQueryInterface to obtain an ITStream pointer from the stream object, and call the stream object's Init method (on the stream object pointer, not the ITStream pointer).

  TERMINAL_DIRECTION Direction,
  IMediaEvent        *pGraph,
  ITStream           **ppStream
);
