      comment out range_check of fdct in dct.c · 08b157da
      Angie Chiang authored
      The range_check is not used because the bit range
      in fdct# is not correct. Since we are going to merge in a new version
      of fdct# from nextgenv2, we won't fix the incorrect bit range now.

      Speed up angle search in intra mode selection · d7c8bc77
      hui su authored
      Estimate angle histogram using gradient analysis, then skip those
      angles that are unlikely to be chosen.
      
      On ext-intra experiment, turning off filter-intra modes:
      for all-key-frame setting, computation overhead is reduced
      by about 40%, coding gain dropped from +2.08% to +1.96% (derflr);
      with kf-max-dist=150, computation overhead is reduced
      by about 60%, coding gain dropped from +0.58% to +0.49% (derflr).

      Reduce transform options for ext-tx experiment · 56ab215d
      Debargha Mukherjee authored
      Reduces the transform optons for INTRA as well as INTER when
      transform size is 16x16 to not use any of the DSTs.
      Thus, a total of 10 options are used for 16x16, while 4x4
      and 8x8 still uses 17 options.
      
      derflr/hevchd actually improves a little, while hevcmr drops
      a little.
      
      About 10% speed improvement.

      Move n8_w and n8_h out of experiment flag · c335bfeb
      Jingning Han authored
      These primitive variables are commonly required by many other
      experiments as well. The use of n4_w and n4_h was originally
      introduced in the vp9 decoder implementation.

      Merge MISC_FIXES · 66f2f65e
      hui su authored
      Remove MISC_FIXES flags except for the changes on MV precision, which
      has a 0.1% performance drop.
      
      On derflr, the impact is -0.012%.

      Coding gain remains about the same, while overall speed is
      substantially increased.
