PFND3DWDDM2_0DDI_VIDEOPROCESSORGETBEHAVIORHINTS callback function (d3d10umddi.h)
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.
Syntax
PFND3DWDDM2_0DDI_VIDEOPROCESSORGETBEHAVIORHINTS Pfnd3dwddm20DdiVideoprocessorgetbehaviorhints;
HRESULT Pfnd3dwddm20DdiVideoprocessorgetbehaviorhints(
D3D10DDI_HDEVICE hDevice,
D3D11_1DDI_HVIDEOPROCESSOR hVideoProcessor,
UINT OutputWidth,
UINT OutputHeight,
DXGI_FORMAT OutputFormat,
UINT StreamCount,
const D3DWDDM2_0DDI_VIDEO_PROCESSOR_STREAM_BEHAVIOR_HINT *pStreams,
UINT *pBehaviorHints
)
{...}
Parameters
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.
hVideoProcessor
Handle to the video processor object.
OutputWidth
Indicates the width of the output surface.
OutputHeight
Indicates the height of the output surface.
OutputFormat
Indicates the output format of the video processor.
StreamCount
The number of input streams to process.
pStreams
An array of structures indicating the format and status of each stream.
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.
Return value
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.
