Constants

 
D3D12DDI_VIDEO_ENCODER_AV1_SEGMENTATION_MODE_0095_DISABLED
Value: 0
Indicates that the use of segmentation is disabled.
D3D12DDI_VIDEO_ENCODER_AV1_SEGMENTATION_MODE_0095_ALT_Q
Value: 1
Indicates that alternative quantization parameters within segments can be used.
D3D12DDI_VIDEO_ENCODER_AV1_SEGMENTATION_MODE_0095_ALT_LF_Y_V
Value: 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
Value: 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
Value: 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
Value: 5
