PFND3DWDDM2_1DDI_VIDEOPROCESSORSETOUTPUTHDRMETADATA callback function (d3d10umddi.h)

  • Article

Implemented by the client driver to include HDR metadata to allow the video processor to optimize video for display. This callback sets the maximum brightness capability (in nits) of the display on which the content will be presented.

Syntax

PFND3DWDDM2_1DDI_VIDEOPROCESSORSETOUTPUTHDRMETADATA Pfnd3dwddm21DdiVideoprocessorsetoutputhdrmetadata;

void Pfnd3dwddm21DdiVideoprocessorsetoutputhdrmetadata(
  D3D10DDI_HDEVICE hDevice,
  D3D11_1DDI_HVIDEOPROCESSOR hVideoProcessor,
  D3DDDI_HDR_METADATA_TYPE Type,
  UINT Size,
  const VOID *pMetaData
)
{...}

Parameters

hDevice

A handle to the display device (graphics context).

hVideoProcessor

A handle to the video processor object.

Type

Indicates the type of the HDR metadata provided.

Size

Indicates the type of the HDR metadata provided.

  • For D3DDDI_HDR_METADATA_TYPE_NONE, the size should be 0.
  • For D3DDDI_HDR_METADATA_TYPE_HDR10, the size is sizeof(D3DDDI_HDR_METADATA_HDR10).

pMetaData

Points to a structure containing the HDR metadata.

  • For D3DDDI_HDR_METADATA_TYPE_NONE, this should be NULL.
  • For D3DDDI_HDR_METADATA_TYPE_HDR10, this is a pointer to a DD3DDDI_HDR_METADATA_HDR10 structure.

Return value

None

Remarks

When processing an HDR stream, the driver may use this brightness information to tone map the video content to optimize it for the output display.
