      Sub8x8 block chroma component inter prediction · e29ea12f
      Jingning Han authored
      Handle the sub8x8 chroma component at the unit of 2x2/4x2/2x4 level
      and use the motion vector inherited from the luma component. This
      improves the coding performance:

      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.

      Add reconstruction using gm parameters · b659281e
      Sarah Parker authored
      This patch only includes inter frame reconstruction using gm
      parameters when GLOBAL_MOTION and/or VP9_HIGHBITDEPTH are enabled.
      GM is not currently used when EXT_INTER or DUAL_FILTER is enabled.
      This will be added in a followup patch. For now, these experiments
      will take precedence over GLOBAL_MOTION when they are all enabled.

      Improve vpx_blend_* functions. · bfa59b4a
      Geza Lore authored
      - Made source buffers pointers to const.
      - Renamed vpx_blend_mask6b to vpx_blend_a64_mask. This is more
        indicative that the function does alpha blending. The 6, or 6b
        suffix was misleading, as the max mask value (64) does not fit into
        6 bits.
      - Added VPX_BLEND_* macros to use when needing to blend scalars.
      - Use VPX_BLEND_A256 in combine_interintra to be more explicit about
        the operation being done.
      - Added versions of vpx_blend_a64_* which take 1D horizontal/vertical
        masks directly and apply them to all rows/columns
        (vpx_blend_a64_hmask and vpx_blend_a64_vmask). The SSE4.1 optimzied
        horizontal version now falls back on the 2D version. This can be
        improved upon if it show up high enough in a profile.
      - All vpx_blend_a64_* functions now support block sizes down to 1x1
        (ie: a single pixel). This is for usage convenience. The SSE4.1
        optimized versions fall back on the C implementation if
        w <= 2 or h <= 2. This can again be improved if it becomes hot code.

      Optimize wedge partition selection. · efda2831
      Geza Lore authored
      We can optimize wedge partition selection by pre-computing the
      residuals of the 2 underlying predictors, and then blend these
      to compute the sse of the compound predictor, without actually
      having to compute and subtract the compound predictor.
      
      Similarly we can pre-compute a proxy array which we can use to
      cheaply check which mask sign would have lower sse.
      
      Details are in wedge_utils.c.
      
      Mathematically these are equivalence transformations, but due to the
      finite precision the encoder output will be perturbed, though on
      average this should make 0% difference.
      
      ext-inter gains about ~4.5% speedup.

      Pre-compute and use contiguous wedge masks. · ab29978e
      Geza Lore authored
      This is purely a refactoring patch and has no functional effect.
      
      Uses of these masks can be arranged such that all input blocks are
      contiguous in memory (stride == block width). In this case 1D versions
      of  operations can be used. 1D vector operations have superior performance
      over 2D block equivalents as they are more processor cache friendly and
      they can do away with a second loop overhead.

      Various wedge enhancements · fb8ea173
      Debargha Mukherjee authored
      Increases number of wedges for smaller block and removes
      wedge coding mode for blocks larger than 32x32.
      
      Also adds various other enhancements for subsequent experimentation,
      including adding provision for multiple smoothing functions
      (though one is used currently), adds a speed feature that decides
      the sign for interinter wedges using a fast mechanism, and refactors
      wedge representations.
      
      lowres: -2.651% BDRATE
      
      Most of the gain is due to increase in codebook size for 8x8 - 16x16.
