A flags enumeration allowing bitwise OR combinations of values from the D3D12_VIDEO_ENCODER_CODEC_CONFIGURATION_H264_SLICES_DEBLOCKING_MODES which specifies the slice deblocking mode as defined by the disable_deblocking_filter_idc syntax in the H.264 specification.

Constants


`D3D12_VIDEO_ENCODER_CODEC_CONFIGURATION_H264_SLICES_DEBLOCKING_MODE_FLAG_NONE` None.
`D3D12_VIDEO_ENCODER_CODEC_CONFIGURATION_H264_SLICES_DEBLOCKING_MODE_FLAG_0_ALL_LUMA_CHROMA_SLICE_BLOCK_EDGES_ALWAYS_FILTERED` disable_deblocking_filter_idc value of 0. All luma and chroma block edges of the slice are filtered.
`D3D12_VIDEO_ENCODER_CODEC_CONFIGURATION_H264_SLICES_DEBLOCKING_MODE_FLAG_1_DISABLE_ALL_SLICE_BLOCK_EDGES` disable_deblocking_filter_idc value of 1. Deblocking is disabled for all block edges of the slice.
`D3D12_VIDEO_ENCODER_CODEC_CONFIGURATION_H264_SLICES_DEBLOCKING_MODE_FLAG_2_DISABLE_SLICE_BOUNDARIES_BLOCKS` disable_deblocking_filter_idc value of 2. All luma and chroma block edges of the slice are filtered with exception of the block edges that coincide with slice boundaries
`D3D12_VIDEO_ENCODER_CODEC_CONFIGURATION_H264_SLICES_DEBLOCKING_MODE_FLAG_3_USE_TWO_STAGE_DEBLOCKING` disable_deblocking_filter_idc value of 3. A two stage deblocking filter process for the slice: After filtering all block luma and chroma block edges that do not coincide with slice boundaries (as if disable_deblocking_filter_idc were equal to 2), the luma and chroma block edges that coincide with slice boundaries are filtered.
`D3D12_VIDEO_ENCODER_CODEC_CONFIGURATION_H264_SLICES_DEBLOCKING_MODE_FLAG_4_DISABLE_CHROMA_BLOCK_EDGES` disable_deblocking_filter_idc value of 4. All luma block edges of the slice are filtered, but the Rec. ITU-T H.264 (06/2019) 477 deblocking of the chroma block edges is disabled.
`D3D12_VIDEO_ENCODER_CODEC_CONFIGURATION_H264_SLICES_DEBLOCKING_MODE_FLAG_5_DISABLE_CHROMA_BLOCK_EDGES_AND_LUMA_BOUNDARIES` disable_deblocking_filter_idc value of 5. All luma block edges of the slice are filtered with exception of the block edges that coincide with slice boundaries (as if disable_deblocking_filter_idc were equal to 2), and that deblocking for chroma block edges of the slice is disabled. 5
`D3D12_VIDEO_ENCODER_CODEC_CONFIGURATION_H264_SLICES_DEBLOCKING_MODE_FLAG_6_DISABLE_CHROMA_BLOCK_EDGES_AND_USE_LUMA_TWO_STAGE_DEBLOCKING` disable_deblocking_filter_idc of 6. The deblocking for chroma block edges is disabled and that the two stage deblocking filter process is used for luma block edges of the slice: After filtering all block luma block edges that do not coincide with slice boundaries (as if disable_deblocking_filter_idc were equal to 2), the luma block edges that coincide with slice boundaries are filtered.
