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:
Return code | Description |
---|---|
S_OK | The video processor enumeration object was created successfully. |
E_OUTOFMEMORY | Memory was not available to complete the operation. |
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.
