Field Documentation
◆ chroma_offset_l0
| int8_t _RocdecHevcSliceParams::chroma_offset_l0[15][2] |
corresponds to HEVC spec variable of the same name.
◆ chroma_offset_l1
| int8_t _RocdecHevcSliceParams::chroma_offset_l1[15][2] |
corresponds to HEVC spec variable of the same name.
◆ collocated_ref_idx
| uint8_t _RocdecHevcSliceParams::collocated_ref_idx |
HEVC syntax element.
◆ delta_luma_weight_l1
| int8_t _RocdecHevcSliceParams::delta_luma_weight_l1[15] |
HEVC syntax element.
◆ dependent_slice_segment_flag
| uint32_t _RocdecHevcSliceParams::dependent_slice_segment_flag |
HEVC syntax element.
◆ five_minus_max_num_merge_cand
| uint8_t _RocdecHevcSliceParams::five_minus_max_num_merge_cand |
HEVC syntax element.
◆ last_slice_of_pic
| uint32_t _RocdecHevcSliceParams::last_slice_of_pic |
current slice is last slice of picture.
◆ slice_data_byte_offset
| uint32_t _RocdecHevcSliceParams::slice_data_byte_offset |
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
| uint32_t _RocdecHevcSliceParams::slice_segment_address |
HEVC syntax element.
