CreateVideoProcessor routine

Creates a video processor object.

Syntax


HRESULT APIENTRY* CreateVideoProcessor(
  _In_  D3D10DDI_HDEVICE hDevice,
  _In_  const D3D11_1DDIARG_CREATEVIDEOPROCESSOR *pCreateData,
  _In_  D3D11_1DDI_HVIDEOPROCESSOR hVideoProcessor,
  _In_  D3D11_1DDI_HRTVIDEOPROCESSOR hRTVideoProcessor
);

Parameters

hDevice [in]

A handle to the display device (graphics context).

pCreateData [in]

A pointer to a D3D11_1DDIARG_CREATEVIDEOPROCESSOR structure. This structure specifies the attributes of the video processor object to be created.

hVideoProcessor [in]

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

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 codeDescription
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.
