PFND3D11_1DDI_GETVIDEOPROCESSORCUSTOMRATE callback function (d3d10umddi.h)
Queries a custom frame rate that is associated with a rate conversion capability group.
Syntax
PFND3D11_1DDI_GETVIDEOPROCESSORCUSTOMRATE Pfnd3d111DdiGetvideoprocessorcustomrate;
void Pfnd3d111DdiGetvideoprocessorcustomrate(
D3D10DDI_HDEVICE unnamedParam1,
D3D11_1DDI_HVIDEOPROCESSORENUM unnamedParam2,
UINT unnamedParam3,
UINT unnamedParam4,
D3D11_1DDI_VIDEO_PROCESSOR_CUSTOM_RATE *unnamedParam5
)
{...}
Parameters
unnamedParam1
hDevice [in]
A handle to the display device (graphics context).
unnamedParam2
hProcessorEnum [in]
A handle to a video processor enumeration object that was created through a call to the CreateVideoProcessorEnum function.
unnamedParam3
CustomRateIndex [in]
The zero-based index of the custom rate to query. For more information, see the Remarks section.
unnamedParam4
RateConversionIndex [in]
The zero-based index of the frame-rate conversion capability group. For more information, see the Remarks section.
unnamedParam5
pRate [out]
A pointer to a D3D11_1DDI_VIDEO_PROCESSOR_CUSTOM_RATE structure that contains the attributes of the specified custom rate.
Return value
None
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.
