Field Documentation

◆ slice_data_bit_offset

uint16_t _RocdecAvcSliceParams::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.
