      Changed to use reference mv as nearest mv · e52e8b70
      Yaowu Xu authored
      The reference motion vector selected by surrounding pixels that has
      the best matching score is used as nearest motion vector.
      
      The change has shown consistent gain on all test sets, compression
      gains range from .2% to .6%. The variation is largely dependent on
      various other experiments on or off.

      Merging in high_precision_mv experiment · 2af5473a
      Deb Mukherjee authored
      Merged in the high_precision_mv experiment to make it easier
      to work on new mv encoding strategies. Also removed
      coef_update_probs3().

      enable interleaved decoding of mode and mv · 2e73f901
      Yaowu Xu authored
      Previouly, the decoding of mode and motion vector are done a per frame
      basis followed by residue decoding and reconstuction. The commit added
      the option to allow decoder to interleave the decoding of mode and mvs
      with the residue decoding on a per MB basis.

      Replacing the 8x8 DCT with 8x8 ADST/DCT for I8x8 · fcbff9ee
      Jingning Han authored
      Fixed the code review comments.
      
      Under the htrans8x8 experiment the 8X8 DCT in the
      I8X8 mode is replaced with a combination of 8X8 ADST and
      DCT.
      
      Overall coding gains with the htrans8x8 experiment are:
      derf:   0.486
      std-hd: 1.040
      hd:     1.063
      yt:     0.506
      
      Note that part of the gain comes from bigger transforms
      (8x8 instead of 4x4) and part comes from replacing the DCT
      wth the ADST.
