Modified Aq1 and Aq2
Aq 1 only updates segment map on kf and arf and
only uses 3 segments. With these settings AQ1 is
+ for most clips in SSIM but negative in psnr.
However, the penalty in PSNR is much less than
previously.
Old version aq1 average results for std hd
-20.899% psnr, -5.809% SSIM
New version aq1 for std hd
-3.57% psnr, +1.23% SSIM
Aq2 Now uses only 2 segments and rd.
This mode is still slightly negative for most clips on
psnr and SSIM but seems to have a much bigger visual
impact on several problem clips than aq mode 1.
Old results for std hd:
-2.578% psnr, -1.151% SSIM
New results for std hd:
-1.561% psnr, -0.85% SSIM
