      Optimize vp9_tree_probs_from_distribution · bd84685f
      John Koleszar authored
      The previous implementation visited each node in the tree multiple times
      because it used each symbol's encoding to revisit the branches taken and
      increment its count. Instead, we can traverse the tree depth first and
      calculate the probabilities and branch counts as we walk back up. The
      complexity goes from somewhere between O(nlogn) and O(n^2) (depending on
      how balanced the tree is) to O(n).
      
      Only tested one clip (256kbps, CIF), saw 13% decoding perf improvement.
      
      Note that this optimization should port trivially to VP8 as well. In VP8,
      the decoder doesn't use this function, but it does routinely show up
      on the profile for realtime encoding.
