\brief HEVC Slice Parameter Buffer Structure For Long Format

VASliceParameterBufferHEVC structure should be accompanied by a slice data buffer, which holds the whole raw slice NAL unit bit streams including start code prefix and emulation prevention bytes not removed.

This structure conveys parameters related to slice segment header and should be sent once per slice.

For short format, this data structure is not sent by application.

Fields

slice_data_size: u32

\brief Number of bytes in the slice data buffer for this slice counting from and including NAL unit header.

slice_data_offset: u32

\brief The offset to the NAL unit header for this slice

slice_data_flag: u32

\brief Slice data buffer flags. See \c VA_SLICE_DATA_FLAG_XXX.

slice_data_byte_offset: u32

\brief Byte offset from NAL unit header to the begining of slice_data().

This byte offset is relative to and includes the NAL unit header and represents the number of bytes parsed in the slice_header() after the removal of any emulation prevention bytes in there. However, the slice data buffer passed to the hardware is the original bitstream, thus including any emulation prevention bytes.

slice_segment_address: u32

HEVC syntax element.

RefPicList: [[u8; 15]; 2]

\brief index into ReferenceFrames[] RefPicList[0][] corresponds to RefPicList0[] of HEVC variable. RefPicList[1][] corresponds to RefPicList1[] of HEVC variable. value range [0..14, 0xFF], where 0xFF indicates invalid entry.

LongSliceFlags: _VASliceParameterBufferHEVC__bindgen_ty_1

collocated_ref_idx: u8

HEVC syntax element. Collocated Reference Picture Index. index to RefPicList[0][] or RefPicList[1][]. when slice_temporal_mvp_enabled_flag equals 0, it should take value 0xFF. value range [0..14, 0xFF].

num_ref_idx_l0_active_minus1: u8

HEVC syntax element. if num_ref_idx_active_override_flag equals 0, host decoder should set its value to num_ref_idx_l0_default_active_minus1.

num_ref_idx_l1_active_minus1: u8

HEVC syntax element. if num_ref_idx_active_override_flag equals 0, host decoder should set its value to num_ref_idx_l1_default_active_minus1.

slice_qp_delta: i8

HEVC syntax element.

slice_cb_qp_offset: i8

HEVC syntax element.

slice_cr_qp_offset: i8

HEVC syntax element.

slice_beta_offset_div2: i8

HEVC syntax element.

slice_tc_offset_div2: i8

HEVC syntax element.

luma_log2_weight_denom: u8

HEVC syntax element.

delta_chroma_log2_weight_denom: i8

HEVC syntax element.

delta_luma_weight_l0: [i8; 15]

HEVC syntax element.

luma_offset_l0: [i8; 15]

HEVC syntax element.

delta_chroma_weight_l0: [[i8; 2]; 15]

HEVC syntax element.

ChromaOffsetL0: [[i8; 2]; 15]

corresponds to HEVC spec variable of the same name.

delta_luma_weight_l1: [i8; 15]

HEVC syntax element.

luma_offset_l1: [i8; 15]

HEVC syntax element.

delta_chroma_weight_l1: [[i8; 2]; 15]

HEVC syntax element.

ChromaOffsetL1: [[i8; 2]; 15]

corresponds to HEVC spec variable of the same name.

five_minus_max_num_merge_cand: u8

HEVC syntax element.

num_entry_point_offsets: u16

HEVC syntax element.

entry_offset_to_subset_array: u16

HEVC syntax element.

slice_data_num_emu_prevn_bytes: u16

\brief Number of emulation prevention bytes in slice header.

va_reserved: [u32; 2]

\brief Reserved bytes for future use, must be zero
