Members

SupportFlags

A bitwise OR combination of flags from the D3D12_VIDEO_ENCODER_CODEC_CONFIGURATION_SUPPORT_HEVC_FLAGS specifying which optional features are supported for the codec.

MinLumaCodingUnitSize

The minimum luma coding block size requested. This value must match what the caller will code in the sequence parameter set (SPS).

MaxLumaCodingUnitSize

The maximum luma coding block size requested. This value matches what the user will code in SPS.

MinLumaTransformUnitSize

The minimum luma transform block size requested. This value matches the pixel size of what the user will code in SPS.log2_min_luma_transform_block_size_minus2.

MaxLumaTransformUnitSize

The maximum luma transform block size requested. This value must be consistent with the pixel size the user will code 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

The maximum hierarchy depth for transform units of coding units coded in inter prediction mode. The value of max_transform_hierarchy_depth_inter shall be in the range of 0 to CtbLog2SizeY − MinTbLog2SizeY, inclusive.

max_transform_hierarchy_depth_intra

Specifies the maximum hierarchy depth for transform units of coding units coded in intra prediction mode. The value of max_transform_hierarchy_depth_intra shall be in the range of 0 to CtbLog2SizeY − MinTbLog2SizeY, inclusive.
