D3D12DDI_VIDEO_ENCODER_CODEC_CONFIGURATION_SUPPORT_H264_FLAGS_0080 enumeration (d3d12umddi.h)

The D3D12DDI_VIDEO_ENCODER_CODEC_CONFIGURATION_SUPPORT_H264_FLAGS_0080 enumeration reports the hardware capabilities for H.264 encoding.

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).

Remarks

See D3D12 video encoding for general information.
