      Explicit MV reference experiment. · ba30e774

      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.

      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.

      Remove test from B_MODE_INFO. · 23a64c89
      Ronald S. Bultje authored
      It is essentially a duplicate of mode for RD-only purposes. Removing it
      saves us 4 bytes per B_MODE_INFO, or ~0.5MB for a 1080p video encode.

      Remove mode_rdopt from MB_MODE_INFO. · 66180f22
      Ronald S. Bultje authored
      The variable is essentially a duplicate of mode for RD-only purposes.
      Removing it gives identical results, and saves 4 bytes per macroblock
      (i.e. 32.5kB for a 1080p HD video encode).

      Add a new token stuffing function vp8_stuff_mb(). · e7881462
      Ronald S. Bultje authored
      This way a caller doesn't need to implement the logic for which (and how
      many) tokens to write out to stuff one macroblock worth of EOBs. Make
      the actual function implementations static, since they are now only used
      in tokenize.c; also do some minor stylistic changes so it follows the
      style guide a little more closely; use PLANE_TYPE where appropriate,
      remove old (stale) frame_type function arguments; hardcode plane type
      where only a single one is possible (2nd order DC or U/V EOB stuffing);
      support stuffing 8x8/4x4 transform EOBs with no 2nd order DC.
