PFND3D11_1DDI_CREATEVIDEOPROCESSORENUM callback function (d3d10umddi.h)

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

Syntax

PFND3D11_1DDI_CREATEVIDEOPROCESSORENUM Pfnd3d111DdiCreatevideoprocessorenum;

HRESULT Pfnd3d111DdiCreatevideoprocessorenum(
  D3D10DDI_HDEVICE unnamedParam1,
  const D3D11_1DDIARG_CREATEVIDEOPROCESSORENUM *unnamedParam2,
  D3D11_1DDI_HVIDEOPROCESSORENUM unnamedParam3,
  D3D11_1DDI_HRTVIDEOPROCESSORENUM unnamedParam4
)
{...}

Parameters

unnamedParam1

hDevice [in]

A handle to the display device (graphics context).

unnamedParam2

pCreateData [in]

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

unnamedParam3

hVideoProcessorEnum [in]

A handle to the driver's private data for the video processor enumeration object.

unnamedParam4

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:

Remarks

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.
