Silence the warnings
ontheflyratectlpass2.cc:383:33: warning: '&&' within '||' [-Wlogical-op-parentheses]
if( actual_bits > target_bits && debiased_target_ABQ > picture.ABQ ||
~~~~~~~~~~~~~~~~~~~~~~~~~~^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ~~
ontheflyratectlpass2.cc:383:33: note: place parentheses around the '&&' expression to silence this warning

Fix the error
acroblock.cc:77:24: warning: & has lower precedence than ==; == will be evaluated first [-Wparentheses]
if( i->mb_type & MB_BACKWARD == 0 && cur_score < best_fwd_score)
^~~~~~~~~~~~~~~~~~
macroblock.cc:77:24: note: place parentheses around the '==' expression to silence this warning
