Constants

 
D3D12DDI_VIDEO_ENCODER_CODEC_CONFIGURATION_SUPPORT_H264_FLAG_0080_NONE
Indicates no flags.
D3D12DDI_VIDEO_ENCODER_CODEC_CONFIGURATION_SUPPORT_H264_FLAG_0080_CABAC_ENCODING_SUPPORT
Indicates whether support is available for context-adaptive binary arithmetic coding (CABAC) Encoding.
D3D12DDI_VIDEO_ENCODER_CODEC_CONFIGURATION_SUPPORT_H264_FLAG_0080_INTRA_SLICE_CONSTRAINED_ENCODING_SUPPORT
Indicates whether support is available for slice constrained 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; that is, motion vectors cannot be used outside the slice boundary.
D3D12DDI_VIDEO_ENCODER_CODEC_CONFIGURATION_SUPPORT_H264_FLAG_0080_BFRAME_LTR_COMBINED_SUPPORT
Indicates whether support is available for using B-frames and long-term references at the same time.
D3D12DDI_VIDEO_ENCODER_CODEC_CONFIGURATION_SUPPORT_H264_FLAG_0080_ADAPTIVE_8x8_TRANSFORM_ENCODING_SUPPORT
Indicates whether support is available for using adaptive 8x8 transforms when encoding.
D3D12DDI_VIDEO_ENCODER_CODEC_CONFIGURATION_SUPPORT_H264_FLAG_0080_DIRECT_SPATIAL_ENCODING_SUPPORT
Indicates support for spatial direct mode.
D3D12DDI_VIDEO_ENCODER_CODEC_CONFIGURATION_SUPPORT_H264_FLAG_0080_DIRECT_TEMPORAL_ENCODING_SUPPORT
Indicates support for temporal direct mode.
D3D12DDI_VIDEO_ENCODER_CODEC_CONFIGURATION_SUPPORT_H264_FLAG_0080_CONSTRAINED_INTRAPREDICTION_SUPPORT
Indicates whether support is available for constrained intra-prediction. When constrained intra-prediction is activated, it forces the encoding of each intra-coded block with residual data only from other intra-coded blocks (and not from inter-coded blocks). This flag refers to constrained_intra_pred_flag in the picture parameter set (PPS).
D3D12DDI_VIDEO_ENCODER_CODEC_CONFIGURATION_SUPPORT_H264_FLAG_0099_0_NUM_REF_IDX_ACTIVE_OVERRIDE_FLAG_SLICE_SUPPORT
Indicates that the encoder supports overriding the number of active reference indices at the slice level. This allows for more fine-grained control of reference frames used for prediction on a per-slice basis. Added in Windows 11, version 24H2 (WDDM 3.2).
