      Simplify redundant code related to prev_frame mvs · 84442629
      Zoe Liu authored
      For the setup of prev_frame and use_prev_frame_mvs, the removed
      code has a copy that already exists inside read_uncompressed_header().

      Remove unused variables for ext-skip · 404d92e7
      Zoe Liu authored
      The removed variable was once defined for evaluating the use of
      distance-weighted compound prediction for the new skip mode, under
      the scenario when all reference frames are forward predicted.

      [lv_map_multi] adjust speed of prob adaptation · 5641635f
      Dake He authored
      Use a lookup table to deterimine speed of adaptation in update_cdf.
      Tests on 5 keyframes show improvement in BD-rate: consistently more
      than -0.2% for google test sets (lowres, midres, hdres).

      [lv_map_multi] multisymbol coding of eob · 0db7d0eb
      Dake He authored
      1. code the range of eob in a transform block as a single symbol.
      2. initialize cdfs directly.
      3. initial cdfs are trained by using laplace prob estimates as in base
      level coding (CL 38638)

      Define separate stage ranges for col/row idtx txfm · c1d9aefa
      Yue Chen authored
      This will clear range check failures related to fwd square txfms
      when using --enable-coefficient_range_checking.

      [lv_map_multi] base level coding · 4d447696
      Dake He authored
      1. Train and init cdfs directly.
      2. Use laplace prob estimates in aom_entropy_optimizer to avoid zero
      probabilities.

      Not signal reference_mode if one ref avaialble · c67d98c6
      Zoe Liu authored
      Use the frame ID that indicates the frame display order to identify
      whether two different reference frames exist for inter-coded frames.
      If there is only one unique reference valid in the reference buffer,
      there is no need to signal reference_mode. Instead, the decoder may
      identify such scenario and set reference_mode to SINGLE_REFERENCE.

      Use and adjust rectangular txfm stage ranges · 901d5148
      Debargha Mukherjee authored
      Adjusst txfm stage ranges so that Cfg tests pass, however
      tests with --enable-coefficient-range-checking are still
      failing. Those are to be addressed subsequently.

      Avoid changing motion_mode after rd search · 6f90fb29
      Angie Chiang authored
      Check if the global motion undergoes non-translation mode. If that
      is the case, do not force a newmv mode into globalmv mode.
      
      This will resolve a mismatch bug of txk_sel.
