      vp9: Nonrd variance partition: improve split to 16x16. · 3135b854
      Marco authored
      Add additional condition to split to 16x16, for resolutions <= 360p,
      reduces dragging artifact near moving boundary.
      
      Small/no change on RTC metrics.

      vp9: Use sb content measure to bias against golden. · 06c8713e
      Marco authored
      For each superblock, keep track of how far from current frame
      was the last significant content change, and use that (along
      with GF distance), to turnoff GF search in non-rd pickmode.
      
      Only enabled for speed >= 8.
      
      avgPNSR on RTC/RTC_derf down by ~0.9/1.2.
      Speedup on mac: ~3-5%.
      Speedup on arm: 3.6% for VGA and 4.4% for HD.

      Record the sum of tx block eobs in the partition block · 9c2552a1
      Yunqing Wang authored
      The sum of tx bloxk eobs is needed in the machine learning based partition
      early termination. The eobs are first accumulated during tx search, and
      then the value associated with the best tx_size is copied to ctx for later
      use.
      
      After the sum of eobs are calculated correctly, re-enabled
      ml_partition_search_early_termination speed feature.
      
      Re-did the quality/speed test to check the impact of the fix.
      
      1. Borg test BDRATE result:
      4k set:     PSNR: +0.183%; SSIM: +0.100%;
      hdres set:  PSNR: +0.168%; SSIM: +0.256%;
      midres set: PSNR: +0.186%; SSIM: +0.326%;
      
      2.Average speed gain result:
      4k clips: 21%;
      hd clips: 26%;
      midres clips: 15%.
      
      The result is in line with the original result.
