      1) Add txb_entropy_ctx into MACROBLOCK_PLANE and PICK_MODE_CONTEXT
      
      2) Add av1_get_txb_entropy_context() to compute the entropy context
      
      3) Compute and sore the entropy context before av1_xform_quant()

      Compute lv_map's coeff cost in av1_cost_coeffs() · 47e4b369
      Angie Chiang authored
      1) move the original implementation in av1_cost_coeffs() to
      cost_coeffs() and let av1_cost_coeffs become a switch for
      choosing original coeff cost or lv_map's coeff cost
      
      2) change get_txb_ctx's naming. Use plane_bsize instead of
      bsize to make the intention clear.
      
      3) remove txb context computing in get_txb_ctx

      Adds binary code lib for coding various symbols · 47748b56
      Debargha Mukherjee authored
      Adds a variable length binary code library for
      coding various symbols for typical use in headers.
      
      The main codes implemented are:
      1. Coding a symbol from an n-ary alphabet using a
      quasi-uniform code.
      2. A bilevel code for coding symbols from an n-ary
      alphabet based on a reference value for the symbol
      also taken from the same alphabet.
      The code has two steps. If the symbol is close to
      the reference a shorter code is used, while if it is
      farther away a longer code is used.
      3. A finite (terminated) subexponential code that codes
      a symbol from an n-ary alphabet using subexp parameter k.
      4. A finite (terminated) subexponential code that codes
      a symbol from an n-ary alphabet using subexp parameter k,
      based on a given reference also taken from the same
      alphabet. This code essentially reorders the values
      before using the same code as 3.
      
      Also adds corresponding encoder side functions to count
      the number of bits used.
      
      These codes will be subsequently used for more efficient
      encoding of loop-restoration parameters and global motion
      parameters.

      Add NEW_MULTISYMBOL experiment. · e60ce831
      Thomas Davies authored
      This experiment is for converting binary symbols in the baseline
      into non-binary symbols. EC_MULTISYMBOL should continue to be used
      by experiments with their own signalling for compatibility.

      Re-enable av1_nmv_ctx() when ext-inter is enabled · 9620bcd5
      David Barker authored
      Currently, mbmi->ref_mv_idx can be set to a nonzero value
      on the encoder side if mbmi->mode is one of NEARMV, NEWMV,
      NEAR_NEARMV, or NEW_NEWMV. But it can only be nonzero on the
      decoder side if the mode is NEARMV or NEWMV. Hence av1_nmv_ctx
      has previously been disabled when ext-inter is enabled, to
      prevent a mismatch due to this.
      
      This patch changes the encoder behaviour to match the decoder
      behaviour.

      Account for 2x2 tx_size in extrabits_size · 008ea46a
      Jingning Han authored
      Offset the transform block size with respect to TX_4X4 when
      counting the cat6 extra bit size. This accounts for the potential
      use of 2x2 transform block size in cb4x4.
