      skip un-neccessary motion search in the first pass · 5daef90e
      Pengchong Jin authored
      This patch allows the encoder to skip the
      un-neccessary motion search in the first pass. It
      calculates the error of the zero motion vector using
      the last source frame as reference and skips the
      further motion search in the first pass if the error
      is small.
      
      The encoding speedup of the first pass for slideshow
      videos is over 30%. Borg test shows the overall PSNR
      performance remain approximately the same (derf -0.009,
      hd 0.387, yt 0.021, stdhd 0.065). Individual clips may
      have either PSNR gain or loss. The worst PSNR perfomance
      is from yt set, with a PSNR loss of -1.1.
