PFND3D11_1DDI_VIDEOPROCESSORSETSTREAMPIXELASPECTRATIO callback function (d3d10umddi.h)

Sets the pixel aspect ratio for an input stream on the video processor.

Syntax

PFND3D11_1DDI_VIDEOPROCESSORSETSTREAMPIXELASPECTRATIO Pfnd3d111DdiVideoprocessorsetstreampixelaspectratio;

void Pfnd3d111DdiVideoprocessorsetstreampixelaspectratio(
  D3D10DDI_HDEVICE unnamedParam1,
  D3D11_1DDI_HVIDEOPROCESSOR unnamedParam2,
  UINT unnamedParam3,
  BOOL unnamedParam4,
  const DXGI_RATIONAL *unnamedParam5,
  const DXGI_RATIONAL *unnamedParam6
)
{...}

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

StreamIndex [in]

The zero-based index of the input stream.

unnamedParam4

Enable [in]

If TRUE, the pSourceRatio and pDestinationRatio parameters contain valid values. Otherwise, the pixel aspect ratios are unspecified.

unnamedParam5

pSourceRatio [in]

A pointer to a DXGI_RATIONAL structure that contains the pixel aspect ratio of the source rectangle.

unnamedParam6

pDestRatio [in]

A pointer to a DXGI_RATIONAL structure that contains the pixel aspect ratio of the destination rectangle.

Return value

None

Remarks

Pixel aspect ratios of the form 0/n and n/0 are not valid.

The default pixel aspect ratio is 1:1 (square pixels).

The driver reports its ability to support the pixel aspect ratio capability 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_PIXEL_ASPECT_RATIO capability, the VideoProcessorSetStreamAlpha can be called to set the pixel aspect ratios for an input stream of the video processor.
