Members

ConfigurationFlags

A D3D12DDI_VIDEO_ENCODER_CODEC_CONFIGURATION_HEVC_FLAGS_0082_0 value that defines the set of enabled features. Flags can be combined.

MinLumaCodingUnitSize

A D3D12DDI_VIDEO_ENCODER_CODEC_CONFIGURATION_HEVC_CUSIZE_0080 value that indicates the minimum luma coding block size to be used in the encoder. This value matches the value coded by the user in the Sequence Parameter Set (SPS).

MaxLumaCodingUnitSize

A D3D12DDI_VIDEO_ENCODER_CODEC_CONFIGURATION_HEVC_CUSIZE_0080 value that indicates the maximum luma coding block size to be used in the encoder. This value matches the value coded by the user in the SPS.

MinLumaTransformUnitSize

A D3D12DDI_VIDEO_ENCODER_CODEC_CONFIGURATION_HEVC_TUSIZE_0082_0 value that indicates the minimum luma transform block size to be used in the encoder. This value matches the pixel size coded by the user in SPS.log2_min_luma_transform_block_size_minus2.

MaxLumaTransformUnitSize

A D3D12DDI_VIDEO_ENCODER_CODEC_CONFIGURATION_HEVC_TUSIZE_0082_0 value that indicates the maximum luma transform block size to be used in the encoder. This value must be consistent with the pixel size coded by the user in SPS.log2_diff_max_min_luma_transform_block_size. The variable MaxTbLog2SizeY is set equal to log2_min_luma_transform_block_size_minus2 + 2 + log2_diff_max_min_luma_transform_block_size.

max_transform_hierarchy_depth_inter

Indicates for the associated encoder, the maximum hierarchy depth for transform units of coding units coded in inter prediction mode. The value of max_transform_hierarchy_depth_inter must be in the range of 0 to CtbLog2SizeY − MinTbLog2SizeY, inclusive. The value of max_transform_hierarchy_depth_inter must be consistent with the user-coded SPS headers.

max_transform_hierarchy_depth_intra

Indicates for the associated encoder, the maximum hierarchy depth for transform units of coding units coded in intra prediction mode. The value of max_transform_hierarchy_depth_intra must be in the range of 0 to CtbLog2SizeY − MinTbLog2SizeY, inclusive. The value of max_transform_hierarchy_depth_intra must be consistent with the user-coded SPS headers.

Remarks

See D3D12 video encoding for general information.
