D3D12DDI_VIDEO_ENCODER_AV1_REFERENCE_WARPED_MOTION_TRANSFORMATION_0095_FLAGS enumeration (d3d12umddi.h)

  • Article

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.

Syntax

typedef enum D3D12DDI_VIDEO_ENCODER_AV1_REFERENCE_WARPED_MOTION_TRANSFORMATION_0095_FLAGS {
  D3D12DDI_VIDEO_ENCODER_AV1_REFERENCE_WARPED_MOTION_TRANSFORMATION_0095_FLAG_NONE,
  D3D12DDI_VIDEO_ENCODER_AV1_REFERENCE_WARPED_MOTION_TRANSFORMATION_0095_FLAG_IDENTITY,
  D3D12DDI_VIDEO_ENCODER_AV1_REFERENCE_WARPED_MOTION_TRANSFORMATION_0095_FLAG_TRANSLATION,
  D3D12DDI_VIDEO_ENCODER_AV1_REFERENCE_WARPED_MOTION_TRANSFORMATION_0095_FLAG_ROTZOOM,
  D3D12DDI_VIDEO_ENCODER_AV1_REFERENCE_WARPED_MOTION_TRANSFORMATION_0095_FLAG_AFFINE
} ;

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.
