PFND3D11_1DDI_CREATEVIDEOPROCESSOR callback function (d3d10umddi.h)
Creates a video processor object.
Syntax
PFND3D11_1DDI_CREATEVIDEOPROCESSOR Pfnd3d111DdiCreatevideoprocessor;
HRESULT Pfnd3d111DdiCreatevideoprocessor(
D3D10DDI_HDEVICE unnamedParam1,
const D3D11_1DDIARG_CREATEVIDEOPROCESSOR *unnamedParam2,
D3D11_1DDI_HVIDEOPROCESSOR unnamedParam3,
D3D11_1DDI_HRTVIDEOPROCESSOR unnamedParam4
)
{...}
Parameters
unnamedParam1
hDevice [in]
A handle to the display device (graphics context).
unnamedParam2
pCreateData [in]
A pointer to a D3D11_1DDIARG_CREATEVIDEOPROCESSOR structure. This structure specifies the attributes of the video processor object to be created.
unnamedParam3
hVideoProcessor [in]
A handle to the driver's private data for the video processor object.
unnamedParam4
hRTVideoProcessor [in]
A handle to the video processor object that the driver should use when it calls back into the Direct3D runtime.
Return value
CreateVideoProcessor returns one of the following values:
| Return code | Description |
|---|---|
| S_OK | The video processor object was created successfully. |
| D3DDDIERR_DEVICEREMOVED | The graphics adapter was removed. |
| E_OUTOFMEMORY | Memory was not available to complete the operation. |
Remarks
The CreateVideoProcessor function creates a video processor object that contains specific capabilities and state. Multiple video processor objects can exist at the same time, each with its own unique state.
The Direct3D runtime calls CreateVideoProcessor after it has called the driver's CalcPrivateVideoProcessorSize to determine the size in bytes for the private data that the driver requires for the video processor 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 object.
When the runtime calls CreateVideoProcessor, it passes the handle to the private data memory in the hProcessor parameter. This handle is actually a pointer to the memory.
