D3D12DDI_VIDEO_DECODE_CONVERSION_SUPPORT_DATA_0032 structure (d3d12umddi.h)

Structure used to check if a color space conversion, format conversion, and scale are supported, and whether it is required for real-time reasons or reference buffer format.

Syntax

typedef struct D3D12DDI_VIDEO_DECODE_CONVERSION_SUPPORT_DATA_0032 {
  UINT                                                NodeIndex;
  D3D12DDI_VIDEO_DECODE_CONFIGURATION_0020            Configuration;
  D3D12DDI_VIDEO_SAMPLE_DESCRIPTION_0020              DecodeSample;
  D3D12DDI_VIDEO_FORMAT_DESCRIPTION_0020              OutputFormat;
  DXGI_RATIONAL                                       FrameRate;
  UINT                                                BitRate;
  D3D12DDI_VIDEO_DECODE_CONVERSION_SUPPORT_FLAGS_0020 SupportFlags;
  D3D12DDI_VIDEO_SCALE_SUPPORT_0032                   ScaleSupport;
} D3D12DDI_VIDEO_DECODE_CONVERSION_SUPPORT_DATA_0032;

Members

NodeIndex

In multi-adapter operation, the NodeIndex indicates which physical adapter of the device this operation applies to.

Configuration

The decode profile and bitstream encryption. See D3D12DDI_VIDEO_DECODE_CONFIGURATION.

DecodeSample

The source decoded as sample description. See D3D12DDI_VIDEO_SAMPLE_DESCRIPTION.

OutputFormat

The output sample description. See D3D12DDI_VIDEO_FORMAT_DESCRIPTION.

FrameRate

The frame rate of the video content. This is used by the driver to determine whether the video can be decoded in real-time.

BitRate

The average bits per second data compression rate for the compressed video stream. This is used by the driver to determine whether the video can be decoded in real-time.

SupportFlags

Supported flags. See D3D12DDI_VIDEO_DECODE_CONVERSION_SUPPORT_FLAGS.

ScaleSupport

Indicates the supported output size range for decode conversion. See D3D12DDI_VIDEO_SCALE_SUPPORT.

Remarks

The check is made through pfnGetCaps with the D3D12DDICAPS_TYPE set to a value of D3D12DDICAPS_TYPE_VIDEO_DECODE_CONVERSION_SUPPORT.

If the color space and format conversion is reported, SupportedFlags will have D3D12DDI_VIDEO_DECODE_SUPPORT_FLAGS_SUPPORTED set. Callers should check ScaleSupport to understand if the scale is supported.
