PFND3D11_1DDI_VIDEOPROCESSORSETSTREAMSOURCERECT callback function

Sets the source rectangle for an input stream on the video processor.

Syntax

PFND3D11_1DDI_VIDEOPROCESSORSETSTREAMSOURCERECT Pfnd3d111DdiVideoprocessorsetstreamsourcerect;

void Pfnd3d111DdiVideoprocessorsetstreamsourcerect(
  D3D10DDI_HDEVICE Arg1,
  D3D11_1DDI_HVIDEOPROCESSOR Arg2,
  UINT Arg3,
  BOOL Arg4,
  const RECT *Arg5
)
{...}

Parameters

Arg1

hDevice [in]

A handle to the display device (graphics context).

Arg2

hVideoProcessor [in]

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

Arg3

StreamIndex [in]

The zero-based index of the input stream.

Arg4

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.

Arg5

pSourceRect [in]

A pointer to a RECT structure that specifies the source rectangle.

Note  If the Enable parameter is FALSE, this parameter is ignored.
 

Return Value

This callback function does not return a value.

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.
