      Compound inter-intra experiment · 0c917fc9
      Deb Mukherjee authored
      A patch on compound inter-intra prediction.
      
      In compound inter-intra prediction, a new predictor for
      16x16 inter coded MBs are obtained by combining a single
      inter predictor with a 16x16 intra predictor, in a manner
      that the weight varies with distance from the top/left
      boundary. The current search strategy is to combine the best
      inter mode with the best intra mode obtained independently.
      
      Results so far:
      
      derf +0.31%
      yt +0.32%
      std-hd +0.35%
      hd +0.42%
      
      It is conceivable that the results would improve somewhat
      with a more thorough search strategy where all intra modes
      are searched given the best mv, or even a joint search for
      the best mv and the best intra mode.

      Don't use hybrid transform (ADST) for superblocks. · 1e3dd49f
      Ronald S. Bultje authored
      This is in line with other cases where we disable ADST if prediction
      size and transform size don't match. Before this patch, the RD loop
      will use ADST for superblocks, but frame encoding/decoding won't.

      New inter mode context · 2669f42b
      Paul Wilkins authored
      This change is a fix / extension of the newbestrefmv
      experiment. As such it is presented without IFDEF.
      
      The change creates a new context for coding inter modes
      in vp9_find_mv_refs(). This replaces the context that
      was previously calculated in vp9_find_near_mvs().
      The new context is unoptimized and not necessarily
      any better at this stage (results pending), but eliminates
      the need for a legacy call to vp9_find_near_mvs().
      Based on numbers from Scott, this could help decode
      speed by several %.
      
      In a later patch I will add support for forward update of
      context (assuming this helps) and refine the context as
      necessary.

      Restrict ref mv search range. · 6fb8953c
      Paul Wilkins authored
      Experiment to test speed trade off of reducing the
      extent of the ref mv search.
      
      Reducing the maximum number of tested candidates to 9 had
      minimal net effect on quality in any of the tests sets.
      
      Reduction to 7 has a small negative impact (worst was STD-HD
      at about -0.2%).
      
      This change is in response to the apparently high number of
      decode cycles reported in regard to mv-ref selection.

      New b-intra mode where direction is contextual · d01357bb
      Deb Mukherjee authored
      Preliminary patch on a new 4x4 intra mode B_CONTEXT_PRED where the
      dominant direction from the context is used to encode. Various decoder
      changes are needed to support decoding of B_CONTEXT_PRED in conjunction
      with hybrid transforms since the scan order and tokenization depends on
      the actual direction of prediction obtained from the context. Currently
      the traditional directional modes are used in conjunction with the
      B_CONTEXT_PRED, which also seems to provide the best results.
      
      The gains are small - in the 0.1% range.

      Explicit MV reference experiment. · ba30e774
      Paul Wilkins authored
      Coding and costing of mv reference signal.
      
      Issues in updating MV ref with COMPANDED_MVREF_THRESH
      to be resolved. Ideally the MV precision should be defined based
      on absolute MV magnitude not as now the MV ref magnitude.
      
      Update to mv counts moved into bitstream.c because otherwise
      if the motion reference is changed at the last minute the encoder
      and decoder get out of step in terms of the counts used to update
      entropy probs.
      
      Code working on a few test clips but no results yet re benefit vs
      signaling cost and no tuning of red loop to test lower cost alternatives
      based on the available reference values.
      
      Patch 3. Added check to make sure we don't pick a reference
      that would give rise to an uncodeable / out of range residual.
      
      Patch 6-7: Attempt to rebase. OK to submit but best to leave flag off for now.
      
      Patch 9. Remove print no longer needed.

      Merging in the Switchable interp experiment · 53731197
      Deb Mukherjee authored
      There is a macro DEFAULT_INTERP_FILTER defined in encoder/onyx_if.c that
      is set as EIGHTTAP for now - so SWITCHABLE is not really used. Ideally,
      this should be SWITCHABLE but that would make the encoder quite a bit slower.
      We will change the default filter to SWITCHABLE once we find a faster way to
      search for switchable filters.

      Separates the logic on transform type selection previously spread out
      over a number of files into a separate function. Currently the tx_type
      field in b_mode_info is not used, but still left in there to eventually
      use for signaling the transform type in the bitstream.
      
      Also, now for tx_type = DCT_DCT, the regular integer DCT is used, as
      opposed to the floating point DCT used in conjuction with hybrid
      transform.
      
      Results change somewhat due to the transform change, but are within
      reasonable limits. The hd/std-hd sets are slightly up, while derf/yt
      are slightly down.
