Description

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.

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.
