Description
In the VVC draft7-vE, sps_subpic_id_present_flag is always signaled in SPS regardless of the value of subpics_present_flag. It might be a type, sps_subpic_id_present_flag signaling should be on condition of subpics_present_flag. The spec. fixing is as follows
seq_parameter_set_rbsp( ) {
…
subpics_present_flag
if( subpics_present_flag ) {
sps_num_subpics_minus1
for( i = 0; i <= sps_num_subpics_minus1; i++ ) {
subpic_ctu_top_left_x[ i ]
subpic_ctu_top_left_y[ i ]
subpic_width_minus1[ i ]
subpic_height_minus1[ i ]
subpic_treated_as_pic_flag[ i ]
loop_filter_across_subpic_enabled_flag[ i ]
}
} (remove this braces)
sps_subpic_id_present_flag
if( sps_subpics_id_present_flag ) {
sps_subpic_id_signalling_present_flag
if( sps_subpics_id_signalling_present_flag ) {
sps_subpic_id_len_minus1
for( i = 0; i <= sps_num_subpics_minus1; i++ )
sps_subpic_id[ i ]
}
}
} (add this braces)
