      Clamp rate error estimate. · 6dbb9e4d
      Paul Wilkins authored
      Add back clamp which ensures that the Q adaptation
      is turned off when the over_shoot_pct and under_shoot_pct
      parameters are set to 100.

      Add adaptation option for VBR. · f7f0eaa5
      Paul Wilkins authored
      Allow min and maxQ to creep when the undershoot
      or overshoot exceeds thresholds controlled by the
      command line under_shoot_pct and over_shoot_pct
      values.
      
      Default is 100%,100% which ~disables adaptation.
      
      Derf results for example undershoot% / overshoot%:-
      
      Head:- Mean abs (%rate error) = 14.4%
      
      This check in:-
      25%/25% - Mean abs (%rate error) = 6.7%
                        PSNR hit -1% SSIM -0.1%
      
      5% / 5%  - Mean abs (%rate error) = 2.2%
                       PSNR hit -3.3% SSIM - 1.1%
      
      Most of the remaining error and most of the quality hit is
      at extreme data rates. The adaptation code still has an
      exception for material that is in effect static so that we
      don't over adjust and over spend on YT slide show type
      content.

      to resolve a auto-merge error)
