ProcAmp Control DDI
So that the Video Mixing Renderer (VMR) can access ProcAmp-control functionality, the display driver must implement the motion compensation callback functions.
To simplify driver development, use motion-compensation code templates and implement the ProcAmp control functions in this section. The functions are member functions of either the deinterlace container device or ProcAmp control device classes. For more information, see Defining the Deinterlace Container Device Class and Defining the ProcAmp Control Device Class.
