CreateVideoDecoderOutputView routine

Creates a resource view for a video decoder. This view defines the output sample for the video decoding operation.

Syntax


HRESULT APIENTRY* CreateVideoDecoderOutputView(
  _In_  D3D10DDI_HDEVICE hDevice,
  _In_  const D3D11_1DDIARG_CREATEVIDEODECODEROUTPUTVIEW *pCreateData,
  _In_  D3D11_1DDI_HVIDEODECODEROUTPUTVIEW hView,
  _In_  D3D11_1DDI_HRTVIDEODECODEROUTPUTVIEW hRTView
);

Parameters

hDevice [in]

A handle to the display device (graphics context).

pCreateData [in]

A pointer to a D3D11_1DDIARG_CREATEVIDEODECODEROUTPUTVIEW structure. This structure specifies the attributes of the video decoder output view to be created.

hView [in]

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

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 codeDescription
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.

Requirements
