      Fix a bug in obmc prediction · 10cdeab4
      Yue Chen authored
      For left side obmc, the input of the mask function is corrected as
      the column coordinate.
      Also, minor fixes for a compiler warning.

      Added vp10_fht4x4_sse2() unit test · 267f73a1
      Yi Luo authored
      Inherited class TransformTestBase to derived class VP10Trans4x4HT.
      Employed RunCoeffCheck() to test vp10_fht4x4_sse2() against
      C reference vp10_fht4x4_c().
      fdst4_sse2() related seven hybrid transform cases are covered
       in this test.
      Wrote a header file for test base class. Some modification to
      make sure the base class can be used for 8x8, 16x16, 32x32 cases.
      All related tests passed.

      Adding speed feature interface for ext tx search · 2ca7d42e
      Sarah Parker authored
      This sets up the interface for 3 speed features that progressively
      eliminate a greater number of transforms in ext tx using
      pre-trained support vector machines.
      Each speed feature still needs to be implemented.

      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.
