VideoProcessorSetOutputAlphaFillMode function

Sets the alpha fill mode for data that the video processor writes to the render target.

Syntax


VOID APIENTRY* VideoProcessorSetOutputAlphaFillMode(
  _In_  D3D10DDI_HDEVICE hDevice,
  _In_  D3D11_1DDI_HVIDEOPROCESSOR hVideoProcessor,
  _In_  D3D11_1DDI_VIDEO_PROCESSOR_ALPHA_FILL_MODE FillMode,
  _In_  UINT StreamIndex
);

Parameters

hDevice [in]

A handle to the display device (graphics context).

hVideoProcessor [in]

A handle to the video processor object that was created through a call to the CreateVideoProcessor function.

FillMode [in]

The alpha fill mode, specified as a D3D11_1DDI_VIDEO_PROCESSOR_ALPHA_FILL_MODE value. For more information, see the Remarks section.

StreamIndex [in]

The zero-based index of an input stream. This parameter is used if the AlphaFillMode parameter is set to D3D11_1DDI_VIDEO_PROCESSOR_ALPHA_FILL_MODE_SOURCE_STREAM. Otherwise, the parameter is ignored.

Return value

This function does not return a value.

Remarks

The driver reports its ability to support alpha fill modes in the D3D11_1DDI_VIDEO_PROCESSOR_CAPS structure that is returned through the GetVideoProcessorCaps function. If the driver supports the D3D11_1DDI_VIDEO_PROCESSOR_FEATURE_CAPS_ALPHA_FILL capability, it supports all of the alpha fill modes that are defined by the D3D11_1DDI_VIDEO_PROCESSOR_ALPHA_FILL_MODE enumeration. Otherwise, the FillMode parameter must be set to D3D11_VIDEO_PROCESSOR_ALPHA_FILL_MODE_OPAQUE.

Note  If the driver does not support the D3D11_1DDI_VIDEO_PROCESSOR_FEATURE_CAPS_ALPHA_FILL capability, the Microsoft Direct3D runtime does not call the VideoProcessorSetOutputAlphaFillMode function.

The default fill mode is D3D11_VIDEO_PROCESSOR_ALPHA_FILL_MODE_OPAQUE.
