      Add adaptive midpoint for AQ1. · fc47c5d6
      Paul Wilkins authored
      Make the midpoint variance used in AQ mode 1 segmentation
      depend on the overall complexity of the frame in two pass.

      Add variance restriction to AQ2. · d0312379
      Paul Wilkins authored
      Add an additional restriction to bit/complexity based
      segmentation based on spatial variance.
      
      Only lower Q when both the number of bits spent
      in the initial encoding pass and the spatial complexity are
      below a threshold. This will prevent the low Q segments
      being used just because there is a surfeit of bits.
      
      Small metrics gains especially opsnr.
      derf ~0.2% std-hd ~0.3%
