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.
