      New mode_info_context storage -- undo revert · ac6093d1
      Scott LaVarnway authored
      mode_info_context was stored as a grid of MODE_INFO structs.
      The grid now constists of pointers to MODE_INFO structs.  The
      MODE_INFO structs are now stored as a stream (decoder only),
      eliminating unnecessary copies and is a little more cache
      friendly.

      For the test clips used, the decoder performance improved
      by ~4.3% (1080p) and ~9.7% (720p).
      
      Patch Set 2: Re-encoded clips with latest. Now ~1.7% (1080p)
      and 5.9% (720p).

      Renaming in MB_MODE_INFO · 26fead7e
      Paul Wilkins authored
      The macro block mode info context originally contained an
      entry for each 16x16 macroblock. In VP9 each entry refers
      to an 8x8 region not a macro block, so the naming is misleading.
      
      This first stage clean up changes the names of 3 entries in the
      structure to remove the mb_ prefix.
      
      TODO clean up the nomenclature more widely in respect of
      mbmi and bmi.

      Merging in the Switchable interp experiment · 53731197
      Deb Mukherjee authored
      There is a macro DEFAULT_INTERP_FILTER defined in encoder/onyx_if.c that
      is set as EIGHTTAP for now - so SWITCHABLE is not really used. Ideally,
      this should be SWITCHABLE but that would make the encoder quite a bit slower.
      We will change the default filter to SWITCHABLE once we find a faster way to
      search for switchable filters.

      TODO: There are still a few fields that should be packed into partition
      0 but are included in partition 1, due to them being serialized from
      write_kfmodes/pack_inter_mode_mvs, which execute after the first
      partition is finalized. These need to be separated out into a separate
      function, similar to mb_mode_mv_init() in decodemv.c.

      Adds support for switchable interpolation filters. · 52597441
      Deb Mukherjee authored
      Allows for swtiching/setting interpolation filters at the MB
      level. A frame level flag indicates whether to use a specifc
      filter for the entire frame or to signal the interpolation
      filter for each MB. When switchable filters are used, the
      encoder chooses between 8-tap and 8-tap sharp filters. The
      code currently has options to explore other variations as well,
      which will be cleaned up subsequently.
      
      One issue with the framework is that encoding is slow. I
      tried to do some tricks to speed things up but it is still slow.
      Decoding speed should not be affected since the number of
      filter taps remain unchanged.
      
      With the current version, we are up 0.5% on derf on average but
      some videos city/mobile improve by close to 4 and 2% respectively.
      If we did a full-search by turning the SEARCH_BEST_FILTER flag
      on, the results are somewhat better.
      
      The framework can be combined with filtered prediction, and I
      seek feedback regarding that.
      
      Rebased.
