      Hybrid partition search for rtc coding mode · 9f128b3e
      Jingning Han authored
      This commit re-designs the recursive partition search scheme in
      rtc speed -5. It first checks if the current block is under cyclic
      refresh mode. If so, apply recursive partition search. Otherwise,
      perform sub-sampled pixel based partition selection. When the
      pre-selection finds the partition size should be 32x32 or above,
      use the partition size directly. Otherwise, apply partition search
      at nearby levels around the preset partition size.
      
      It is enabled in speed -5. The compression performance of rtc
      speed -5 is improved by 9.4%. Speed wise, the run-time goes slower
      from 1% to 10%.
