Constants

 
D3D12_VIDEO_ENCODER_CODEC_CONFIGURATION_SUPPORT_HEVC_FLAG_NONE
None.
D3D12_VIDEO_ENCODER_CODEC_CONFIGURATION_SUPPORT_HEVC_FLAG_BFRAME_LTR_COMBINED_SUPPORT
Support for usage of B frames and long term references frames simultaneously.
D3D12_VIDEO_ENCODER_CODEC_CONFIGURATION_SUPPORT_HEVC_FLAG_INTRA_SLICE_CONSTRAINED_ENCODING_SUPPORT
Support for slice-contrained encoding, in which every slice in a frame is encoded independently from other slices in the same frame. This mode restricts the motion vector search range to the region box of the current slice, e.g. motion vectors outside the slice boundary can't be used.
D3D12_VIDEO_ENCODER_CODEC_CONFIGURATION_SUPPORT_HEVC_FLAG_CONSTRAINED_INTRAPREDICTION_SUPPORT
Support for constrained intraprediction, that if activated will force the encoding of each intra-coded block with residual data only from other intra-coded blocks, e.g. not from inter-coded blocks. This refers to constrained_intra_pred_flag in the picture parameter set (PPS).
D3D12_VIDEO_ENCODER_CODEC_CONFIGURATION_SUPPORT_HEVC_FLAG_SAO_FILTER_SUPPORT
Support for sample adaptive offset.
D3D12_VIDEO_ENCODER_CODEC_CONFIGURATION_SUPPORT_HEVC_FLAG_ASYMETRIC_MOTION_PARTITION_SUPPORT
Support for asymmetric motion partition.
D3D12_VIDEO_ENCODER_CODEC_CONFIGURATION_SUPPORT_HEVC_FLAG_ASYMETRIC_MOTION_PARTITION_REQUIRED
Asymmetric motion partition must be always enabled. If this flag is set, D3D12_VIDEO_ENCODER_CODEC_CONFIGURATION_SUPPORT_HEVC_FLAG_ASYMETRIC_MOTION_PARTITION_SUPPORT must also be set.
D3D12_VIDEO_ENCODER_CODEC_CONFIGURATION_SUPPORT_HEVC_FLAG_TRANSFORM_SKIP_SUPPORT
Support for transform skip.
D3D12_VIDEO_ENCODER_CODEC_CONFIGURATION_SUPPORT_HEVC_FLAG_DISABLING_LOOP_FILTER_ACROSS_SLICES_SUPPORT
Support for disabling loop filter across slices.
D3D12_VIDEO_ENCODER_CODEC_CONFIGURATION_SUPPORT_HEVC_FLAG_P_FRAMES_IMPLEMENTED_AS_LOW_DELAY_B_FRAMES
When this flag is set, indicates that when encoding frames with type D3D12_VIDEO_ENCODER_FRAME_TYPE_HEVC_P_FRAME, they will be written as low delay B-Frames in the compressed bitstream. When this flag is not set, indicates that P frames will be written in the compressed bitstream.

Note When operating under this mode, it is the caller's responsibility to code the correct frame type in AUD_NUT and other parts of the HEVC bitstream, taking into account that P frames will be treated as generalized B frames with only references to past frames in POC order.
