      Some cleanups and fixes. · f3208f36
      Deb Mukherjee authored
      Separates the logic on transform type selection previously spread out
      over a number of files into a separate function. Currently the tx_type
      field in b_mode_info is not used, but still left in there to eventually
      use for signaling the transform type in the bitstream.
      
      Also, now for tx_type = DCT_DCT, the regular integer DCT is used, as
      opposed to the floating point DCT used in conjuction with hybrid
      transform.
      
      Results change somewhat due to the transform change, but are within
      reasonable limits. The hd/std-hd sets are slightly up, while derf/yt
      are slightly down.

      Remove test from B_MODE_INFO. · 23a64c89
      Ronald S. Bultje authored
      It is essentially a duplicate of mode for RD-only purposes. Removing it
      saves us 4 bytes per B_MODE_INFO, or ~0.5MB for a 1080p video encode.

      Remove mode_rdopt from MB_MODE_INFO. · 66180f22
      Ronald S. Bultje authored
      The variable is essentially a duplicate of mode for RD-only purposes.
      Removing it gives identical results, and saves 4 bytes per macroblock
      (i.e. 32.5kB for a 1080p HD video encode).

      Add and consistently use PLANE_TYPE. · 41e3a9ef
      Ronald S. Bultje authored
      Change the macros PLANE_TYPE_{Y_NO_DC,Y2,UV,Y_WITH_DC} to a typed enum,
      and use this typed enum consistently across all places where relevant.
      In places where the type is implied (e.g. in functions that only handle
      second order planes or chroma planes), remove it as a function argument
      and instead hardcode the proper enum in the code directly.

      Entropy coding for hybrid transform · 3f5d60b3
      Deb Mukherjee authored
      Separates the entropy coding context models for 4x4, 8x8 and 16x16
      ADST variants.
      
      There is a small improvement for HD (hd/std-hd) by about 0.1-0.2%.
      Results on derf/yt are about the same, probably because there is not
      enough statistics.
      
      Results may improve somewhat once the initial probability tables are
      updated for the hybrid transforms which is coming soon.

      Separating 8x8DCT use from hybridtransform8x8 · 70e21afb
      Deb Mukherjee authored
      With this change, even if hybridtransform8x8 experiment is off,
      8x8 dct is used for the I8x8 mode. However note that the gains
      observed with the hybridtransform8x8 experiment will now be less,
      since part of the gain is now merged in.

      Partial merge of NEWBESTREFMV and NEW_MVREF. · 778ec421
      Paul Wilkins authored
      This commit merges those parts of the CONFIG_NEW_MVREF
      that specifically relate to choosing a better set of candidate
      MV references into the NEWBESTREFMV experiment.
      
      CONFIG_NEW_MVREF will then be used for changes relating
      to the explicit coding of a cost optimized MV reference in the
      bitstream as part of MV coding.

      MV reference changes · 38e1c791
      Paul Wilkins authored
      Extend experiment to use both vectors from MBs
      coded using compound prediction as candidates.
      
      In final sort only consider best 4 candidates
      for now but make sure 0,0 is always one of them.
      
      Other minor changes to new MV reference code.
      Pass in Mv list to vp8_find_best_ref_mvs().
