      Do sub-pixel motion search in up-sampled reference frames · 342a368f
      Yunqing Wang authored
      Up-sampled the reference frames to 8 times in each dimension using
      the 8-tap interpolation filter. In sub-pixel motion search, use the
      up-sampled reference frames to find the best matching blocks. This
      largely improved the motion search precision, and thus, improved
      the compression quality. There was no change in decoder side.
      
      Borg test and speed test results:
      1. On derflr set,
      Overall PSNR gain: 1.306%, and SSIM gain: 1.512%.
      Average speed loss on derf set was 6.0%.
      2. On stdhd set,
      Overall PSNR gain: 0.754%, and SSIM gain: 0.814%.
      On hevchd set,
      Overall PSNR gain: 0.465%, and SSIM gain: 0.527%.
      Speed loss on HD clips was 3.5%.

      A build fix and some other cosmetic changes · db084506
      Debargha Mukherjee authored
      Fixes some issues introduced by a merge of two patches.
      Also decouples the temporal interpolation filter from the switchable
      filters for now for ease of experimentation with both separately.
