PFND3DWDDM2_0DDI_CHECKVIDEOPROCESSORFORMATCONVERSION callback function

Description

Indicates whether the driver supports a specific format/color-space conversion combination. This function must be implemented by 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.

`hProcessorEnum`

A handle to a video processor enumeration object that was created through a call to the CreateVideoProcessorEnum function.

`pConversion`

A pointer to a D3DWDDM2_0DDI_CHECK_VIDEO_PROCESSOR_FORMAT_CONVERSION structure that contains the input and output format/color-space combination.
