      Optimize operation flow in sub8x8 rd loop · 409e77f2
      Jingning Han authored
      Stack the rate-distortion statistics in the sub8x8 rd loop. This allows
      the encoder to skip the forward transform, quantization, and coeff cost
      estimation, in the sub8x8 rd optimization search, if the motion
      vector(s) are of integer pixel value, and have been tested in the
      previous prediction filter type rd loops of the same block.
      
      This gives about 2% speed-up for bus_cif at 2000 kpbs, for speed 0.
      Its efficacy depends how frequently the motion search will select an
      integer motion vector.
