D3D12_VIDEO_ENCODER_RESOLVE_METADATA_OUTPUT_PSNR_RESOLVED_LAYOUT structure (d3d12video.h)

Describes the resolved PSNR (Peak Signal-to-Noise Ratio) values for the Y, U, and V components of an encoded frame or subregion.

Syntax

typedef struct D3D12_VIDEO_ENCODER_RESOLVE_METADATA_OUTPUT_PSNR_RESOLVED_LAYOUT {
  float PSNRY;
  float PSNRU;
  float PSNRV;
} D3D12_VIDEO_ENCODER_RESOLVE_METADATA_OUTPUT_PSNR_RESOLVED_LAYOUT;

Members

PSNRY

The PSNR value for the Y (luma) component.

PSNRU

The PSNR value for the U (chroma) component. Set to zero by the driver if not supported.

PSNRV

The PSNR value for the V (chroma) component. Set to zero by the driver if not supported.

Remarks

The number of available components is determined by D3D12_FEATURE_DATA_VIDEO_ENCODER_RESOURCE_REQUIREMENTS1. Components not supported by the driver are written as zero.

For subregion-level PSNR, the resolved buffer contains a packed array of this structure with one element per subregion.
