Add extra case to wq_err_divisor() Add extra case for 360P and smaller. This hurts a little in psnr for the derf cif set but helps a little in terms of average rate accuracy. Most clips come in a little smaller with this patch. No impact on larger formats. Change-Id: I5056246cb53b90f961ff9ea5813937f33778aa4c
