      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.

      Should fix B_PRED-related encoder/decoder mismatches.

      Faster 8t filtering · ce811f87
      Scott LaVarnway authored
      Quickly modified the ssse3 sixtap filters to support eight taps.  For the test
      clip used, a 23+% boost in decoder performance was seen.  We can
      revisit later and improve further.

      sse2 intrinsic version of vp8_mbloop_filter_vertical_edge() · 085433c2
      Scott LaVarnway authored
      First sse2 version of vp8_mbloop_filter_vertical_edge().  For now,
      intrinsics are being used until the bitstream is finalized.  This function
      will be revisited later for further performance improvements.
      
      For the test clip used, a 34+% decoder performance improvement
      was seen.  This will vary depending on material.

      calculate probs consistently · 91dc8ce7
      John Koleszar authored
      There were several different methods for calculating bitstream
      probabilities in use. Consolodate these into a pair of functions,
      get_prob() and get_binary_prob().

      Remove bc, bc2 from pbi,cpi,xd · e9fd1eac
      John Koleszar authored
      Pass the bool coder to be used explicitly. This avoids cases where two
      different bool coders can be addressed from the same function. Also be
      more consistent with bool coder variable naming, start to standardize
      on 'bc'.

      Some cleanups and fixes. · f3208f36
      Deb Mukherjee authored
      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.
