GetVideoProcessorCustomRate function

Queries a custom frame rate that is associated with a rate conversion capability group.

Syntax


VOID APIENTRY* GetVideoProcessorCustomRate(
  _In_   D3D10DDI_HDEVICE hDevice,
  _In_   D3D11_1DDI_HVIDEOPROCESSORENUM hProcessorEnum,
  _In_   UINT RateConversionIndex,
  _In_   UINT CustomRateIndex,
  _Out_  D3D11_1DDI_VIDEO_PROCESSOR_CUSTOM_RATE *pRate
);

Parameters

hDevice [in]

A handle to the display device (graphics context).

hProcessorEnum [in]

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

RateConversionIndex [in]

The zero-based index of the frame-rate conversion capability group. For more information, see the Remarks section.

CustomRateIndex [in]

The zero-based index of the custom rate to query. For more information, see the Remarks section.

pRate [out]

A pointer to a D3D11_1DDI_VIDEO_PROCESSOR_CUSTOM_RATE structure that contains the attributes of the specified custom rate.

Return value

This function does not return a value.

Remarks

The display miniport driver returns the maximum number of frame-rate conversion capabilities that it supports through the RateConversionCapsCount member of the D3D11_1DDI_VIDEO_PROCESSOR_CAPS structure. The driver returns a pointer to this structure through its GetVideoProcessorCaps function. In addition, the attributes of a frame-rate conversion capability group can be queried by calling the GetVideoProcessorCaps function.
