PFND3D11_1DDI_CREATEVIDEODECODEROUTPUTVIEW callback function (d3d10umddi.h)
Creates a resource view for a video decoder. This view defines the output sample for the video decoding operation.
Syntax
PFND3D11_1DDI_CREATEVIDEODECODEROUTPUTVIEW Pfnd3d111DdiCreatevideodecoderoutputview;
HRESULT Pfnd3d111DdiCreatevideodecoderoutputview(
D3D10DDI_HDEVICE unnamedParam1,
const D3D11_1DDIARG_CREATEVIDEODECODEROUTPUTVIEW *unnamedParam2,
D3D11_1DDI_HVIDEODECODEROUTPUTVIEW unnamedParam3,
D3D11_1DDI_HRTVIDEODECODEROUTPUTVIEW unnamedParam4
)
{...}
Parameters
unnamedParam1
hDevice [in]
A handle to the display device (graphics context).
unnamedParam2
pCreateData [in]
A pointer to a D3D11_1DDIARG_CREATEVIDEODECODEROUTPUTVIEW structure. This structure specifies the attributes of the video decoder output view to be created.
unnamedParam3
hView [in]
A handle to the driver's private data for the video decoder output view.
unnamedParam4
hRTView [in]
A handle to the video decoder output view that the driver should use when it calls back into the Direct3D runtime.
Return value
CreateVideoDecoderOutputView returns one of the following values:
| Return code | Description |
|---|---|
| S_OK | The video decoder output view was created successfully. |
| D3DDDIERR_DEVICEREMOVED | The graphics adapter was removed. |
| E_OUTOFMEMORY | Memory was not available to complete the operation. |
Remarks
The Direct3D runtime calls CreateVideoDecoderOutputView after it has called the driver's CalcPrivateVideoProcessorOutputViewSize to determine the size in bytes for the private data that the driver requires for the video decoder 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 decoder object.
When the runtime calls CreateVideoDecoderOutputView, it passes the handle to the private data memory in the hView parameter. This handle is actually a pointer to the memory.
