Constants


`D3D12DDI_VIDEO_ENCODER_CODEC_CONFIGURATION_HEVC_FLAG_0082_0_NONE` Value: 0x0 No flags are specified.
`D3D12DDI_VIDEO_ENCODER_CODEC_CONFIGURATION_HEVC_FLAG_0082_0_DISABLE_LOOP_FILTER_ACROSS_SLICES` Value: 0x1 If set, disable the loop filtering across slices.
`D3D12DDI_VIDEO_ENCODER_CODEC_CONFIGURATION_HEVC_FLAG_0082_0_ALLOW_REQUEST_INTRA_CONSTRAINED_SLICES` Value: 0x2 If set, allows the use of the intra constrained slices flag in picture control. This mode restricts the motion vector search range to the region box of the current slice (that is, motion vectors outside the slice boundary cannot be used).
`D3D12DDI_VIDEO_ENCODER_CODEC_CONFIGURATION_HEVC_FLAG_0082_0_ENABLE_SAO_FILTER` Value: 0x4 If set, enables the sample adaptive offset filter.
`D3D12DDI_VIDEO_ENCODER_CODEC_CONFIGURATION_HEVC_FLAG_0082_0_ENABLE_LONG_TERM_REFERENCES` Value: 0x8 If set, enables the use of long-term references in the picture reference management structures for HEVC.
`D3D12DDI_VIDEO_ENCODER_CODEC_CONFIGURATION_HEVC_FLAG_0082_0_USE_ASYMETRIC_MOTION_PARTITION` Value: 0x10 If set, enables asymmetric motion partitioning. If D3D12DDI_VIDEO_ENCODER_CODEC_CONFIGURATION_SUPPORT_HEVC_FLAG_0083_0_ASYMETRIC_MOTION_PARTITION_REQUIRED was reported, this flag must always be enabled.
`D3D12DDI_VIDEO_ENCODER_CODEC_CONFIGURATION_HEVC_FLAG_0082_0_ENABLE_TRANSFORM_SKIPPING` Value: 0x20 If set, enables transform skipping.
`D3D12DDI_VIDEO_ENCODER_CODEC_CONFIGURATION_HEVC_FLAG_0082_0_USE_CONSTRAINED_INTRAPREDICTION` Value: 0x40 If set, enables constrained intra prediction. This value refers to constrained_intra_pred_flag in the Picture Parameter Set (PPS).

Remarks

The host (D3D12 lower-level encoding API) sets these configuration flags based on the limits queried at the API level.

See D3D12 video encoding for general information.
