Sets the source rectangle for an input stream on the video processor.
unnamedParam1hDevice [in]
A handle to the display device (graphics context).
unnamedParam2hVideoProcessor [in]
A handle to the video processor object that was created through a call to the CreateVideoProcessor function.
unnamedParam3StreamIndex [in]
The zero-based index of the input stream.
unnamedParam4Enable [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.
unnamedParam5pSourceRect [in]
A pointer to a RECT structure that specifies the source rectangle.
Note If the Enable parameter is FALSE, this parameter is ignored.
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.
