      Add 2x2 block unit syntax · f1702dde
      Jingning Han authored
      Add 2x2 block size syntax to the codec system. It prepares for the
      4x4 coding block unit for 420 format. This change retains the same
      coding statistics.

      Code cleanup: mainly rd_pick_partition and methods called from there. · 52648448
      Urvang Joshi authored
      - Const correctness
      - Refactoring
      - Make variables local when possible etc
      - Remove -Wcast-qual to allow explicitly casting away const.
      
      Cherry-picked from aomedia/master: c27fcccc
      And then a number of more const correctness changes to make sure other
      experiments build OK.

      Wrap palette code inside CONFIG_PALETTE flag. · b100db7c
      Urvang Joshi authored
      This flag was already added to aomedia/master, so bringing it back to
      webm/nextgenv2, as part of an effort to get the two codebases in sync.

      Enable tile-adaptive restoration · 5cd2ab95
      Debargha Mukherjee authored
      Includes a major refactoring/enhancement to support
      tile-adaptive switchable restoration. The framework can be
      readily extended to add more restoration schemes in the
      future. Also includes various cleanups and fixes.
      
      Specifically the framework allows restoration to be conducted
      on tiles such that each tile can be either left unrestored, or
      use bilateral or wiener filtering.
      
      There is a modest improvemnt in coding efficiency (0.1 - 0.2%).
      
      Further enhancements will be added subsequently to improve coding
      efficiency and complexity.

      Insert extra ARFs' in a gf group · 41d5d52d
      Wei-ting Lin authored
      Insert multiple arfs in a gf group to emulate multi-layer backward
      reference frames structure. At maximum, two extra ARF's are inserted
      in a gf group.
      
      It improves the RD performance by 0.317% in Avg in lowres dataset.

      Rectangular transforms 4x8 & 8x4 · e5848dea
      Debargha Mukherjee authored
      Added a new expt rect-tx to be used in conjunction with ext-tx.
      [rect-tx is a temporary config flag and will eventually be
      merged into ext-tx once it works correctly with all other
      experiments].
      
      Added 4x8 and 8x4 tranforms for use initially with rectangular
      sub8x8 y blocks as part of this experiment.
      
      There is about a -0.2% BDRATE improvement on lowres, others pending.
      
      When var-tx is on rectangular transforms are currently not used.
      That will be enabled in a subsequent patch.

      Merge bi-predictive frames to EXT_REFS · 5805a14c
      Zoe Liu authored
      This patch removed the experiment of BIDIR_PRED and merged the feature
      into the experiment of EXT_REFS:
      
      (1) Each frame now has up to 6 reference frames, namely
          LAST_FRAME, LAST2_FRAME, LAST3_FRAME, GOLDEN_FRAME, (forward) and
          BWDREF_FRAME, ALTREF_FRAME (backward);
          LAST4_FRAME has been removed;
      (2) First pass still keeps the 8 updates:
          KF_UPDATE, LF_UPDATE, GF_UPDATE, ARF_UPDATE, OVERLAY_UPDATE, and
          BRF_UPDATE, LAST_BIPRED_UPDATE, BI_PRED_UPDATE;
      (3) show_existing_frame==1 is supported in the experiment of EXT_REFS;
      (4) New encoding modes are added for both single-ref and compound cases,
          through the use of the 2 extra forward references (LAST2 & LAST3)
          and the 1 extra backward reference (BWDREF).
      
      RD performance wise, using Overall PSNR: Avg/BDRate
              Bipred only      Prev EXT_REFS    Current EXT_REFS with bipred
      lowres: -3.474/-3.324    -1.748/-1.586    -4.613/-4.387

      If in vp10/encoder/firstpass.h, change BFG_INTERVAL from 2 to 3, i.e. to
      use 2 bi-predictive frames than 1, a further improvement may be
      obtained:
