      Update encoder to use fb_idx_ref_cnt · 394b0a6a
      John Koleszar authored
      Do reference counting the same way on the encoder as the decoder does,
      rather than maintaining the 'flags' member of YV12_BUFFER_CONFIG.

      Remove buffer-to-buffer copy logic · b8e02798
      John Koleszar authored
      This is the first in a series of commits to add additional reference
      frames to the codec. Each frame will be able to update any of the
      available references, but copying between references is not
      supported.

      Further enhancements/fixes on dct/dwt hybrid txfm · 516db21c
      Deb Mukherjee authored
      Fixes some scaling issues. Adds an option to only compute the
      dct on the low-low subband for 32x32 and 64x64 blocks using
      only a single 16x16 dct after 1 and 2 wavelet decomposition
      levels respectively. Also adds an option to use a 8x8 dct
      as building block.
      
      Currenlty with the 2/6 filter and with a single 16x16 dct on
      the low low band, the reuslts compared to full 32x32 dct is
      as follows:
      derf: -0.15%
      yt: -0.29%
      std-hd: -0.18%
      hd: -0.6%
      These are my current recommended settings, since the 2/6 filter
      is very simple.
      
      Results with 8x8 dct are about 0.3% worse.

      New prediction filter · 7d6b5425
      Adrian Grange authored
      This patch removes the old pred-filter experiment and replaces it
      with one that is implemented using the switchable filter framework.
      
      If the pred-filter experiment is enabled, three interopolation
      filters are tested during mode selection; the standard 8-tap
      interpolation filter, a sharp 8-tap filter and a (new) 8-tap
      smoothing filter.
      
      The 6-tap filter code has been preserved for now and if the
      enable-6tap experiment is enabled (in addition to the pred-filter
      experiment) the original 6-tap filter replaces the new 8-tap smooth
      filter in the switchable mode.
      
      The new experiment applies the prediction filter in cases of a
      fractional-pel motion vector. Future patches will apply the filter
      where the mv is pel-aligned and also to intra predicted blocks.
