PFND3DWDDM2_0DDI_QUERYVIDEOCAPABILITIES queries the driver for its video capabilities. WDDM 2.0 or later drivers must implement this function.
[in] 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.
[in] A D3DWDDM2_0DDI_VIDEO_CAPABILITY_QUERY value that indicates the type of data being queried.
[in] Size in bytes of the data that pData points to. This value is dependent on the QueryType member. For example, if QueryType is D3DWDDM2_0DDI_VIDEO_CAPABILITY_QUERY_DECODER_CAPS, set DataSize to sizeof(D3DWDDM2_0DDI_VIDEO_CAPABILITY_DECODER_CAPS).
[in/out] Pointer to a structure containing both caller-provided input parameters and output parameters that are to be filled in by the driver. The type of structure depends on the value of QueryType.
