D3D12DDI_VIDEO_ENCODER_AV1_REFERENCE_PICTURE_WARPED_MOTION_INFO_0095 structure (d3d12umddi.h)

  • Article

The D3D12DDI_VIDEO_ENCODER_AV1_REFERENCE_PICTURE_WARPED_MOTION_INFO_0095 structure defines the information necessary to apply a warped motion transformation to a reference picture in AV1 encoding.

Syntax

typedef struct D3D12DDI_VIDEO_ENCODER_AV1_REFERENCE_PICTURE_WARPED_MOTION_INFO_0095 {
  D3D12DDI_VIDEO_ENCODER_AV1_REFERENCE_WARPED_MOTION_TRANSFORMATION_0095 TransformationType;
  INT                                                                    TransformationMatrix[8];
  BOOL                                                                   InvalidAffineSet;
} D3D12DDI_VIDEO_ENCODER_AV1_REFERENCE_PICTURE_WARPED_MOTION_INFO_0095;

Members

TransformationType

A D3D12DDI_VIDEO_ENCODER_AV1_REFERENCE_WARPED_MOTION_TRANSFORMATION_0095 enumeration value that specifies the type of warped motion transformation to apply.

TransformationMatrix[8]

This array consists of integers that represent the parameters of the transformation matrix for the warped motion. The exact usage of these parameters depends on the TransformationType.

InvalidAffineSet

Remarks

This structure is related to warped motion transformation/global motion type. It indicates the transform(s) to be applied to motion vectors.

See D3D12 AV1 video encoding for more information.
