PFND3D11_1DDI_VIDEOPROCESSORSETSTREAMSOURCERECT callback function (d3d10umddi.h)
Sets the source rectangle for an input stream on the video processor.
Syntax
PFND3D11_1DDI_VIDEOPROCESSORSETSTREAMSOURCERECT Pfnd3d111DdiVideoprocessorsetstreamsourcerect;
void Pfnd3d111DdiVideoprocessorsetstreamsourcerect(
D3D10DDI_HDEVICE unnamedParam1,
D3D11_1DDI_HVIDEOPROCESSOR unnamedParam2,
UINT unnamedParam3,
BOOL unnamedParam4,
const RECT *unnamedParam5
)
{...}
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 specified source rectangle must be applied to the input stream.
If FALSE, no source rectangle is applied to the input stream.
unnamedParam5
pSourceRect [in]
A pointer to a RECT structure that specifies the source rectangle.
Return value
None
Remarks
The source rectangle is the portion of the input surface from which the video processor performs a bit-block transfer (bitblt) to the destination surface. The source rectangle is given in pixel coordinates, relative to the input surface.
If the VideoProcessorSetStreamSourceRect function is never called, or if the Enable parameter is FALSE, the video processor reads from the entire input surface.
