      Further firstpass.c changes. · acf3c729
      Paul Wilkins authored
      base the static image test off a measure of 0,0 motion
      instead of the decay accumulator value.
      Change "transition to still detection" to compare the
      decay rate from successive frames.
      Minor tweak to the arf extra boost given based on the
      number of frames affected.
      Removed unused variable mod_err_per_mb_accumulator.

      Firstpass.c refactoring · 0529320a
      Paul Wilkins authored
      Removed unused function.
      Added tentative code to take error score of an older frame
      into account when calculating Q range. However, for now
      it is disabled pending merging other changes and testing.

      Two pass refactoring continued. · e237fd7c
      Paul Wilkins authored
      Remove testing of whether we estimate that it will be possible
      to code an arf at a lower Q than the ambient Q.  This adds quite
      a bit of extra code and complexity for marginal gain.
      Factored out some code relating to ARNR selection to a separate
      function as this is likely to be changed / simplified soon.

      Two pass rc refactoring. · 59a5c7d5
      Paul Wilkins authored
      Removed odd *100 >> 4 factor from boost calculations. Not all the
      calculations exactly match what was there before so there may be
      some minor impact on results.
      Some other minor tidying up in regard to coding conventions.
      The specific values of factors and thresholds will likely change as
      part of subsequent patches.

      First pass overhaul preparatory change. · 35358320
      Paul Wilkins authored
      This is the first patch in a series of changes to the first
      pass code. (Broken down for ease of testing/merging/review).
      This patch introduces a new stats element "sr_coded_error".
      This is the coded error recorded vs the second reference
      frame (which is updated such that it lags by at least one frame).
      No use is made of the new structure in this change so this patch
      should have no material effect.
      Removed some ifdefs and deprecated code (#if NEW_BOOST).
      Removed twopass.gf_decay_rate (not used any more)

      a number of fixes to entropy stats collection · 54cf1d9a
      Yaowu Xu authored
      1. block types
      There are only three types of blocks for 8x8 transformed MBs, i.e. Y
      block with DC does not exist for 8x8 transformed MBs as all MB using
      8x8 transform have 2nd order haar transform. This commit introduced
      a new macro BLOCK_TYPES_8X8 to reflect such fact.
      2. context counters
      This commit also fixed the mixed of context_counters between 4x4 and
      8x8 transformed MBs. The mixed use of the counters leads me to think
      the existing the context probabilities were not properly generated
      from 8x8 transformed MBs.
      3. redundant collecting in recoding
      The commit also corrected the code that accumulates entropy stats by
      making sure stats only collected for final packing, not during the
      recode loop

      slight adjustment to coef band definition · bd69b7d4
      Yaowu Xu authored
      This commit adjusted slightly the 4x4 coefficents band definition to
      better classify coefficients with similar distributions and usages.
      It helps derf set about .1%, it is alos slightly positive for std-hd
      set, where 4x4 blocks are used less frequently.
      The commit also removed a const array not in use.

      Removed MV costing from ARNR filtering · 393440db
      Adrian Grange authored
      The ARNR filter uses a motion compensated temporal filter,
      but the motion estimation implementation accounts for the
      cost of the mv in its decision making process. The ARNR
      filter uses a dummy cost table initialized to 0 as a way
      to ignore the mv costs (which are irrelevant to the filter).
      This CL modifies the ARNR filter implementation to so that
      the mv costing is ignored without the requirement for
      dummy tables.

      Adds search option for best interpolation filter. · acdda50a
      Deb Mukherjee authored
      Adds a speed feature to conduct a brute force search among a set of
      available interpolation filters for the best one in an RD sense.
      There is a gain of 0.4% on derf, 1.0% on Std-HD.
      Patch 2: A macro added to determine if the encoder state is reset
      for each new filter tried.
      Patch 3: rebase, also fixes a bug (decodframe.c) introduced by a
      couple of missing function pointer assignements.
      Patch 4: rebase.

      the encoding of intra coding modes on key frame only, the overall
      effect of the experiment on encoding tests is insignificant.

      change to allow 8x8 transform always · ade43d91
      Yaowu Xu authored
      This commit changed to enable the usage 8x8 transform for all frame
      type, all resolution and all quantizer range. This has an overall
      benefit .2% to .3% in term of compression, but more importantly,
      the difficult clips benefits much more, up to 2% to 3% on clips
      like football, harbour and so on.
      We observed some weird humps on very high end on a couple of youtube
      clips, but have determined the underly cause was the aggressive zbin
      having an effect of lowering rate with lower quality, which have
      an impact on slide show clips around 60DB.
      The commit does not change the association between prediction mode
      and transform size.

      Added code to save the coding context in vp8_rd_pick_inter_mode

      Also, modified the MV bounds computation to comply with the
      change in MV border from 32 to 64 pixels.

      Turning off interpolation filter selection · 237718dc
      Deb Mukherjee authored
      Turning off the interpolation filter selection based on edge
      proportion. This heuristics has not been working as well as
      expected and I have started a more rigorous investigation into
      this. We can turn this off for now since it is unnecessarily
      slowing things down.

      a set of minor fixes · 636b2f38
      Yaowu Xu authored
      This commit tries to address an issue related to the oddity shown on
      HD _mobcal clip, where some rather ugly blocks shown in the second
      frame at low-mid bit rates if the third frame is not made a key frame
      by he encoder. The fixes include: 1)  made calls to sad_16x16 to be
      consistent with function prototype. 2) remove the error bias to intra
      and golden in mbgraph search. 3) changed the error accumulation on
      inter_segment encoding to avoid potential out-of-range. 1) has no
      effect on encoding results.
      Encoding test show that the overall effect of the commit helps about
      .2%(HD) to .3%(cif)

      Yaowu Xu authored
      The commit removed a limit on key frame detection, which caused a big
      drop in all metric measurements for standard HD clip such as _mobcal.
      This single change helps two standard HD clips by a huge amount, which
      help the overall std-hd set by 2.4% (glb psnr), 0.9% (avg_psnr), 2.1%
      In the result page:
      represent the encoding test results and std-hd set prior and after this
