PFND3DWDDM2_0DDI_VIDEOPROCESSORSETOUTPUTSHADERUSAGE callback function

Description

Sets the color space information for the video processor output surface. Optional for Windows Display Driver Model (WDDM) 2.0, or later, drivers.

Parameters

`hDevice`

A handle to the display device (graphics context). The Direct3D runtime passed the user-mode driver this handle as the hDevice member of the D3DDDIARG_CREATEDEVICE structure at device creation.

`hVideoProcessor`

A handle to the video processor object.

`ShaderUsage`

Indicates whether the output of VideoProcessorBlt may be read by Direct3D shaders.

Note This will always be TRUE unless multi-plane overlay hardware exists.
