      Remove saturate_int16 from fdct_round_shift · 48c06da2
      Angie Chiang authored
      1) Not every transform's internal signal is designed to fit in 16 bits.
      2) If overflow happens in this function, it indicates that we need to
      adjust the txfm's scaling. We shouldn't mute the overflow signal.
      3) Saturation might be handy when all of our transform design are stable,
      but I don't think we are at the stable point yet.
      4) This will fix C/Trans16x16DCT.AccuracyCheck/1 failure in highbd mode.

      Remove temporary intra condition check in cb4x4 mode · 54e24517
      Jingning Han authored
      The previous refactoring CLs resolve all the potential issue
      related to these two conditions. It is safe to remove them now
      from the cb4x4 mode.

      Make mi_width/height_log2_lookup table support 4x4 mode_info unit · bcf62ea4
      Jingning Han authored
      Change the table content to support 4x4 mode_info unit. Refactor
      partition_plane_context() to reflect the fact that the minimum
      partition block size is 8x8.

      Rework av1_has_right() and av1_has_bottom() · 5f7bc741
      Jingning Han authored
      Replace the 4x4 block counting with minimum transform block size
      counting. This retains identical coding statistics.

      Support affine/homography models for global motion · b0f6bd44
      Debargha Mukherjee authored
      With this patch affine or homography models can be enabled
      by simply changing the value of the GLOBAL_TRANS_TYPES
      macro in common/mv.h to 4 and 5 respectively. Currently
      it is left at supporting only rotzoom. There is a small
      gain with enabling affine.
      
      Also refactors costing to change based on the model type.

      Improve rdopt decisions for ext-inter · ac37fa3d
      David Barker authored
      Relative to previous ext-inter:
      lowres: -0.177%
           or -0.029% (with USE_RECT_INTERINTRA = 0)
      
      * When predicting interintra modes, the previous code did not provide
        the intra predictor with the correct context during rdopt. Add an
        explicit 'ctx' parameter to the relevant functions, to provide this
        context.
        This fixes a nondeterminism bug, which was causing test failures in
        *EncoderThreadTest*
      
      * For rectangular blocks, build_intra_predictors_for_interintra needs
        to overwrite part of the context buffer in order to set up the
        correct context for intra prediction. We now restore the original
        contents afterwards.
      
      * Add a flag to enable/disable rectangular interintra prediction;
        disabling improves encoding speed but reduces BDRATE improvement.

      Handle the block offset using min transform block size · 81492267
      Jingning Han authored
      Map the block offset to pixel positions in the unit of minimum
      transform block size. This change retains the same coding
      statistics. The encoding speed is slightly faster (<1%).

      Add domain transform recursive filter · 3981be93

      This filter is meant to replace the bilateral filter,
      but is currently added in addition to the bilateral filter
      for testing.
