PFND3DWDDM2_0DDI_VIDEOPROCESSORGETBEHAVIORHINTS callback function

-description

Returns driver hints as to which video processor operations are best performed using multi-plane overlay hardware rather than VideoProcessorBlt. Optional for Windows Display Driver Model (WDDM) 2.0, or later, drivers.

-parameters

-param hDevice

A handle to the display device (graphics context). The Direct3D runtime passed the user-mode driver this handle as the hDevice member of the D3DDDIARG_CREATEDEVICE structure at device creation.

-param hVideoProcessor

Handle to the video processor object.

-param OutputWidth

Indicates the width of the output surface.

-param OutputHeight

Indicates the height of the output surface.

-param OutputFormat

Indicates the output format of the video processor.

-param StreamCount

The number of input streams to process.

-param pStreams

An array of structures indicating the format and status of each stream.

-param pBehaviorHints

Receives a combination of D3DWDDM2_0DDI_VIDEO_PROCESSOR_MULTIPLANE_BEHAVIOR_HINTS values indicting which of the operations would best be performed using multi-plane overlay hardware rather than with VideoProcessorBlt.

-returns

If this callback function succeeds, it returns S_OK. Otherwise, it returns an HRESULT error code.

-remarks

This function uses the current state, set via the VideoProcessorSetOutput and VideoProcessorSetStream set of device driver interfaces (DDIs), and returns which operations could be performed more efficiently using multiple overlay hardware.
