Constants
D3D12DDI_VIDEO_ENCODER_AV1_FEATURE_0095_FLAG_NONEValue: 0x0 Indicates that no features are supported. |
D3D12DDI_VIDEO_ENCODER_AV1_FEATURE_0095_FLAG_128x128_SUPERBLOCKValue: 0x1 Indicates whether support is available for 128x128 Superblocks. |
D3D12DDI_VIDEO_ENCODER_AV1_FEATURE_0095_FLAG_FILTER_INTRAValue: 0x2 Indicates whether support is available for intra prediction filter. |
D3D12DDI_VIDEO_ENCODER_AV1_FEATURE_0095_FLAG_INTRA_EDGE_FILTERValue: 0x4 Indicates whether support is available for intra edge filtering process. |
D3D12DDI_VIDEO_ENCODER_AV1_FEATURE_0095_FLAG_INTERINTRA_COMPOUNDValue: 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_COMPOUNDValue: 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_MOTIONValue: 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_FILTERValue: 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_COMPValue: 0x80 Indicates whether support is available for the scenario where distance weights process may be used for inter prediction. |
