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

Syntax

PFND3D11_1DDI_VIDEOPROCESSORSETOUTPUTALPHAFILLMODE Pfnd3d111DdiVideoprocessorsetoutputalphafillmode;

void Pfnd3d111DdiVideoprocessorsetoutputalphafillmode(
  D3D10DDI_HDEVICE unnamedParam1,
  D3D11_1DDI_HVIDEOPROCESSOR unnamedParam2,
  D3D11_1DDI_VIDEO_PROCESSOR_ALPHA_FILL_MODE unnamedParam3,
  UINT unnamedParam4
)
{...}

Parameters

unnamedParam1

hDevice [in]

A handle to the display device (graphics context).

unnamedParam2

hVideoProcessor [in]

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

unnamedParam3

FillMode [in]

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

unnamedParam4

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

None

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.
