      Reuse inter prediction pixel block for Hadamard transform · 8a927a1b
      Jingning Han authored
      It saves one unnecessary motion compensated prediction constructed
      by using 8-tap filter.

      Hadamard transform based coding mode decision process · 8c411f74
      Jingning Han authored
      This commit uses Hadamard transform based rate-distortion cost
      estimate for rtc coding mode decision. It improves the compression
      performance of speed -6 for many hard clips at lower bit-rates.
      For example, 5.5% for jimredvga, 6.7% for mmmoving, 6.1% for
      niklas720p. This will introduce extra encoding cycle costs at
      this point.

      vp9_pred_mv(): misc fixes and optimizations · 9fd8abc5
      Yaowu Xu authored
      1. skip near if it is same as nearest
      2. correct rounding for converting mv to fullpel position
      3. update pred_mv_sad after new mv search.
      
      Overall .1%~.25% compression gains on rtc set for speed 5, 6, 7, 8.
