Windows Driver Kit DDI reference (ne-d3d12umddi-d3d12ddi_video_encoder_av1_segmentation_mode_0095)

Description

The D3D12DDI_VIDEO_ENCODER_AV1_SEGMENTATION_MODE_0095 enumeration defines the distinct segmentation modes that can be used for the segmentation map in the AV1 video encoding process.

Constants

`D3D12DDI_VIDEO_ENCODER_AV1_SEGMENTATION_MODE_0095_DISABLED:0`

Indicates that the use of segmentation is disabled.

`D3D12DDI_VIDEO_ENCODER_AV1_SEGMENTATION_MODE_0095_ALT_Q:1`

Indicates that alternative quantization parameters within segments can be used.

`D3D12DDI_VIDEO_ENCODER_AV1_SEGMENTATION_MODE_0095_ALT_LF_Y_V:2`

Indicates that alternative lvertical oop filter strengths for the luma (Y) component can be used.

`D3D12DDI_VIDEO_ENCODER_AV1_SEGMENTATION_MODE_0095_ALT_LF_Y_H:3`

Indicates that alternative horizontal loop filter strengths for the luma (Y) component can be used.

`D3D12DDI_VIDEO_ENCODER_AV1_SEGMENTATION_MODE_0095_ALT_LF_U:4`

Indicates that alternative loop filter strengths for the chroma (U) component can be used.

`D3D12DDI_VIDEO_ENCODER_AV1_SEGMENTATION_MODE_0095_ALT_LF_V:5`

Indicates that alternative loop filter strengths for the chroma (V) component can be used.

`D3D12DDI_VIDEO_ENCODER_AV1_SEGMENTATION_MODE_0095_ALT_REF_FRAME:6`

Indicates that alternative reference frame selection can be used.

`D3D12DDI_VIDEO_ENCODER_AV1_SEGMENTATION_MODE_0095_ALT_SKIP:7`

Indicates whether certain segments should be skipped (i.e., encoded using inter prediction modes only).

`D3D12DDI_VIDEO_ENCODER_AV1_SEGMENTATION_MODE_0095_ALT_GLOBALMV:8`

Indicates that alternative global motion vector parameters can be used.
