CreateVideoProcessorInputView routine

Creates a resource view for a video processor. This view defines the input sample for the video processing operation.

Syntax


HRESULT APIENTRY* CreateVideoProcessorInputView(
  _In_  D3D10DDI_HDEVICE hDevice,
  _In_  const D3D11_1DDIARG_CREATEVIDEOPROCESSORINPUTVIEW *pView,
  _In_  D3D11_1DDI_HVIDEOPROCESSORINPUTVIEW hView,
  _In_  D3D11_1DDI_HRTVIDEOPROCESSORINPUTVIEW hRTView
);

Parameters

hDevice [in]

A handle to the display device (graphics context).

pView [in]

A pointer to a D3D11_1DDIARG_CREATEVIDEOPROCESSORINPUTVIEW structure. This structure specifies the attributes of the video processor input view to be created.

hView [in]

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

hRTView [in]

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

Return value

CreateVideoProcessorInputView returns one of the following values:

Return codeDescription
S_OK

The video processor input view was created successfully.

D3DDDIERR_DEVICEREMOVED

The graphics adapter was removed.

DXGI_ERROR_UNSUPPORTED

The D3D11_1DDIARG_CREATEVIDEOPROCESSORINPUTVIEW contained incorrect or unsupported data. For example, the driver should return DXGI_ERROR_UNSUPPORTED if the FourCC member specified an unsupported code value.

E_OUTOFMEMORY

Memory was not available to complete the operation.

 

Remarks

The Direct3D runtime calls CreateVideoProcessorInputView after it has called the driver's CalcPrivateVideoProcessorInputViewSize to determine the size in bytes for the private data that the driver requires for the video processor input view. 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 input view.

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

Requirements
