Detailed Description

H.264 Slice Parameter Buffer

Member Data Documentation

◆ num_ref_idx_l0_active_minus1

uint8_t VASliceParameterBufferH264::num_ref_idx_l0_active_minus1

H264/AVC 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

uint8_t VASliceParameterBufferH264::num_ref_idx_l1_active_minus1

H264/AVC 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_data_bit_offset

uint16_t VASliceParameterBufferH264::slice_data_bit_offset

Bit offset from NAL Header Unit to the begining of slice_data().

This bit offset is relative to and includes the NAL unit byte and represents the number of bits 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.
