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.

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.
