      AV1 offline probability optimizer · c8b38b0b

      This tool is a gadget for offline probability training.
      
      A binary executable aom_entropy_optimizer will be generated in
      tools/. It parses a binary file consisting of counts written in
      the format of FRAME_COUNTS in entropymode.h, and computes the
      optimized probability table, which will be written to a new c file
      optimized_probs.c using the format in entropymode.c.
      
      Command line:
      ./aom_entropy_optimizer [directory of the count file]
      
      The input file can be either be generated from a single run by
      turning on entropy_stats experiment(counts are accumulated from
      frame to frame, and finally written to counts.stt), or be collected
      at a larger scale, at which a python script (will be provided soon)
      can be used to aggregate multiple stats output.
      
      Optimization for initial CDFs will be also supported later.
