Description

The D3D12DDI_VIDEO_ENCODER_AV1_FEATURE_0095_FLAGS enumeration is a bitwise OR of values that report the encoding capabilities of the AV1 codec.

Constants

`D3D12DDI_VIDEO_ENCODER_AV1_FEATURE_0095_FLAG_NONE:0x0`

Indicates that no features are supported.

`D3D12DDI_VIDEO_ENCODER_AV1_FEATURE_0095_FLAG_128x128_SUPERBLOCK:0x1`

Indicates whether support is available for 128x128 Superblocks.

`D3D12DDI_VIDEO_ENCODER_AV1_FEATURE_0095_FLAG_FILTER_INTRA:0x2`

Indicates whether support is available for intra prediction filter.

`D3D12DDI_VIDEO_ENCODER_AV1_FEATURE_0095_FLAG_INTRA_EDGE_FILTER:0x4`

Indicates whether support is available for intra edge filtering process.

`D3D12DDI_VIDEO_ENCODER_AV1_FEATURE_0095_FLAG_INTERINTRA_COMPOUND:0x8`

Indicates whether support is available for interintra, where the mode info for inter blocks may contain the syntax element interintra. A value of 0 specifies that the syntax element interintra will not be present.

`D3D12DDI_VIDEO_ENCODER_AV1_FEATURE_0095_FLAG_MASKED_COMPOUND:0x10`

Indicates whether support is available for masked compound, where the mode info for inter blocks may contain the syntax element compound_type. A value of 0 specifies that the syntax element compound_type will not be present.

`D3D12DDI_VIDEO_ENCODER_AV1_FEATURE_0095_FLAG_WARPED_MOTION:0x20`

A value of 1 indicates that the syntax element motion_mode may be present. A value of 0 indicates the syntax element motion_mode will not be present (this means that LOCALWARP cannot be signaled if this flag is equal to 0).

Related to AV1 syntax enable_warped_motion in the sequence header.

`D3D12DDI_VIDEO_ENCODER_AV1_FEATURE_0095_FLAG_DUAL_FILTER:0x40`

Indicates whether support is available for dual filter mode, where the inter prediction filter type may be specified independently in the horizontal and vertical directions. If the flag is equal to 0, only one filter type may be specified, which is then used in both directions.

`D3D12DDI_VIDEO_ENCODER_AV1_FEATURE_0095_FLAG_JNT_COMP:0x80`

Indicates whether support is available for the scenario where distance weights process may be used for inter prediction.

`D3D12DDI_VIDEO_ENCODER_AV1_FEATURE_0095_FLAG_FORCED_INTEGER_MOTION_VECTORS:0x100`

Indicates whether support is available for using the syntax element force_integer_mv.

`D3D12DDI_VIDEO_ENCODER_AV1_FEATURE_0095_FLAG_SUPER_RESOLUTION:0x200`

Indicates whether support is available for super resolution.

`D3D12DDI_VIDEO_ENCODER_AV1_FEATURE_0095_FLAG_LOOP_RESTORATION_FILTER:0x400`

Indicates whether support is available for loop restoration filtering.

`D3D12DDI_VIDEO_ENCODER_AV1_FEATURE_0095_FLAG_PALETTE_ENCODING:0x800`

Indicates whether support is available for frame level control on palette encoding; a value of 0 indicates that palette encoding is never used.

`D3D12DDI_VIDEO_ENCODER_AV1_FEATURE_0095_FLAG_CDEF_FILTERING:0x1000`

Indicates whether support is available for constrained directional enhancement filtering.

`D3D12DDI_VIDEO_ENCODER_AV1_FEATURE_0095_FLAG_INTRA_BLOCK_COPY:0x2000`

Indicates whether intra block copy is supported or not at frame level. Same syntax as AV1 spec.

`D3D12DDI_VIDEO_ENCODER_AV1_FEATURE_0095_FLAG_FRAME_REFERENCE_MOTION_VECTORS:0x4000`

Indicates whether support is available for use_ref_frame_mvs to be configured on a per frame basis. A value of 0 specifies that use_ref_frame_mvs syntax element will not be used.

`D3D12DDI_VIDEO_ENCODER_AV1_FEATURE_0095_FLAG_ORDER_HINT_TOOLS:0x8000`

Indicates whether support is available for usage of tools based on the values of order hints. A value of 0 indicates that tools based on order hints are not supported and can't be enabled.

`D3D12DDI_VIDEO_ENCODER_AV1_FEATURE_0095_FLAG_AUTO_SEGMENTATION:0x10000`

Indicates whether the driver can perform segmentation without API Client input and return segmentation_params() information in D3D12_VIDEO_ENCODER_AV1_POST_ENCODE_VALUES. Driver will write the segment map in the compressed bitstream.

`D3D12DDI_VIDEO_ENCODER_AV1_FEATURE_0095_FLAG_CUSTOM_SEGMENTATION:0x20000`

Indicates whether the driver supports the API Client passing customized segmentation segmentation_params() as well as the segment map and driver will honor exactly.

`D3D12DDI_VIDEO_ENCODER_AV1_FEATURE_0095_FLAG_LOOP_FILTER_DELTAS:0x40000`

Indicates whether the driver supports use of loop filter deltas. Related to loop_filter_delta_enabled AV1 syntax in loop_filter_params().

`D3D12DDI_VIDEO_ENCODER_AV1_FEATURE_0095_FLAG_QUANTIZATION_DELTAS:0x80000`

Indicates whether the driver supports use of quantization delta syntax.

`D3D12DDI_VIDEO_ENCODER_AV1_FEATURE_0095_FLAG_QUANTIZATION_MATRIX:0x100000`

Indicates whether the driver supports use of quantization matrix syntax.

`D3D12DDI_VIDEO_ENCODER_AV1_FEATURE_0095_FLAG_REDUCED_TX_SET:0x200000`

Indicates whether driver supports setting reduced_tx_set in the frame header or must be always set to zero.

`D3D12DDI_VIDEO_ENCODER_AV1_FEATURE_0095_FLAG_MOTION_MODE_SWITCHABLE:0x400000`

Indicates whether driver supports setting is_motion_mode_switchable in the frame header or must be always set to zero.

Indicates whether driver supports setting allow_high_precision_mv in the frame header or must be always set to zero.

`D3D12DDI_VIDEO_ENCODER_AV1_FEATURE_0095_FLAG_SKIP_MODE_PRESENT:0x1000000`

Indicates whether driver supports setting skip_mode_present in the frame header or must be always set to zero.

`D3D12DDI_VIDEO_ENCODER_AV1_FEATURE_0095_FLAG_DELTA_LF_PARAMS:0x2000000`

Indicates whether the driver supports use of loop filter delta params syntax. Related to delta_lf_params() AV1 syntax.
