CreateVideoProcessorEnum routine

Creates an enumeration object for the video processor capabilities of the driver.


HRESULT APIENTRY* CreateVideoProcessorEnum(
  _In_  D3D10DDI_HDEVICE                       hDevice,
  _In_  D3D11_1DDI_HVIDEOPROCESSORENUM         hVideoProcessorEnum,
  _In_  D3D11_1DDI_HRTVIDEOPROCESSORENUM       hRTVideoProcessorEnum


hDevice [in]

A handle to the display device (graphics context).

pCreateData [in]

A pointer to a D3D11_1DDIARG_CREATEVIDEOPROCESSORENUM structure. This structure specifies the attributes of the video processor enumeration object to be created.

hVideoProcessorEnum [in]

A handle to the driver's private data for the video processor enumeration object. For more information, see the Remarks section.

hRTVideoProcessorEnum [in]

A handle to the video processor enumeration object that the driver should use when it calls back into the Direct3D runtime.

Return value

CreateVideoProcessorEnum returns one of the following values:

Return codeDescription

The video processor enumeration object was created successfully.


Memory was not available to complete the operation.



The Direct3D runtime calls CreateVideoProcessorEnum after it has called the driver's CalcPrivateVideoProcessorEnumSize to determine the size in bytes for the private data that the driver requires for the video processor enumeration object. The runtime allocates the memory for this private data for the driver. The driver uses this memory to store private data that is related to the video processor enumeration object.

When the runtime calls CreateVideoProcessorEnum, it passes the handle to the private data memory in the hVideoProcessorEnum parameter. This handle is actually a pointer to the memory.
