Description

The D3D12DDI_VIDEO_ENCODER_AV1_RESTORATION_TILESIZE_0095 corresponds to the size of loop restoration units, in units of samples in the current plane.

Constants

`D3D12DDI_VIDEO_ENCODER_AV1_RESTORATION_TILESIZE_0095_DISABLED:0`

Indicates that no loop restoration is to be applied.

`D3D12DDI_VIDEO_ENCODER_AV1_RESTORATION_TILESIZE_0095_32x32:1`

Indicates that the loop restoration tile size is 32x32.

`D3D12DDI_VIDEO_ENCODER_AV1_RESTORATION_TILESIZE_0095_64x64:2`

Indicates that the loop restoration tile size is 64x64.

`D3D12DDI_VIDEO_ENCODER_AV1_RESTORATION_TILESIZE_0095_128x128:3`

Indicates that the loop restoration tile size is 128x128.

`D3D12DDI_VIDEO_ENCODER_AV1_RESTORATION_TILESIZE_0095_256x256:4`

Indicates that the loop restoration tile size is 256x256.

Remarks

The enum values are based on lr_unit_shift and lr_uv_shift in lr_params() AV1 syntax and the RESTORATION_TILESIZE_MAX(256) AV1 spec constant.

See D3D12 AV1 video encoding for more information.
