      Account for rate error in GF group Q calculation. · 8d7f53f0
      paulwilkins authored
      When GF group adaptive maxQ is enabled this patch accounts
      somewhat for accumulated error in the rate control.
      This improves accuracy quite a bit on many clips especially
      when there is  overshoot.
      Examples when the overshoot and undershoot command line
      parameters are set to 100:
      Hall @ 1200 overshoot is reduced from 67-24%.
      Akiyo @ 400 undershoot is reduced from 28%-15%.
      Setting a lower value for undershoot or overshoot still
      reduces the error further.
      Impact on metrics is mixed with some gains in average psnr
      but generally a little lower (e.g. 0.5%) on overall and ssim.
      The GF group adaptation is still off by default in this patch.
      Compared to with the head, enabling this mode now gives
      big average psnr gains on the YT sets (e.g. YT_HD >11.2%),
      a drop in overall PSNR (YT-HD 3.9%) and a smaller drop or
      neutral for SSIM.
