Description

  1. In equation (37), the direct_ref_layer_flag[ i ][ j ] should be vps_direct_ref_layer_flag[ i ][ j ]
  1. The vps_output_layer_mode in 8.1.2 should be ols_mode_idc
  1. In 7.4.3.4, "scaling_win_left_offset, scaling_win_right_offset, scaling_win_top_offset, and scaling_win_bottom_offset specify the offsets that are applied to the picture size for scaling ratio calculation. When not present, the values of scaling_win_left_offset, scaling_win_right_offset, scaling_win_top_offset, and scaling_win_bottom_offset are inferred to be equal to SubWidthC * conf_win_left_offset, SubWidthC * conf_win_right_offset, SubHeightC * conf_win_top_offset, and SubHeightC * conf_win_bottom_offset, respectively."

Here, the SubWidthC and SubHeightC should be removed since the scaling_win_left_offset, scaling_win_right_offset, scaling_win_top_offset, and scaling_win_bottom_offset are changed to chroma sample unit.
