Windows Driver Kit DDI reference (ne-d3d12umddi-d3d12ddi_video_encoder_av1_reference_warped_motion_transformation_0095_flags)

Description

The D3D12DDI_VIDEO_ENCODER_AV1_REFERENCE_WARPED_MOTION_TRANSFORMATION_0095_FLAGS enumeration defines flags that indicate the type(s) of warped motion transformations that can be applied to reference frames in AV1 encoding.

Constants

`D3D12DDI_VIDEO_ENCODER_AV1_REFERENCE_WARPED_MOTION_TRANSFORMATION_0095_FLAG_NONE`

No warped motion transformation types are supported, and therefore, the encoder will not use warped motion for reference frames.

`D3D12DDI_VIDEO_ENCODER_AV1_REFERENCE_WARPED_MOTION_TRANSFORMATION_0095_FLAG_IDENTITY`

Indicates support for the identity transformation, where the reference frame is not transformed.

`D3D12DDI_VIDEO_ENCODER_AV1_REFERENCE_WARPED_MOTION_TRANSFORMATION_0095_FLAG_TRANSLATION`

Indicates support for the translation transformation.

`D3D12DDI_VIDEO_ENCODER_AV1_REFERENCE_WARPED_MOTION_TRANSFORMATION_0095_FLAG_ROTZOOM`

Indicates support for the rotation and zoom transformation.

`D3D12DDI_VIDEO_ENCODER_AV1_REFERENCE_WARPED_MOTION_TRANSFORMATION_0095_FLAG_AFFINE`

Indicates support for the affine transformation.

Remarks

If only D3D12DDI_VIDEO_ENCODER_AV1_REFERENCE_WARPED_MOTION_TRANSFORMATION_0095_FLAG_NONE is supported, reference warp motion arguments are ignored and AV1 is_global syntax is false for all references.

See D3D12 AV1 video encoding for more information.
