      Fix the printf format string · 8af3e650
      Adrian Grange authored
      There were two problems with the format string in
      the conditionally compiled print statement. It referred
      to a variable that is no longer available and it used
      incorrect format specifiers.

      Fixes to buffer update for temporal layers. · 41138e01
      Marco Paniconi authored
      When a frame is dropped due to |buffer_level| < 0 for a given temporal layer,
      the buffer level for the upper temporal layers was not updated (in calc_pframe_target_size()).
      This change fixes that.
      
      Also, use the layer per-frame-bandwidth for updating the buffer level
      of the higher layers when a frame is dropped.

      Updates to qp-regulate and rate correction factor. · 464b1df6
      Marco Paniconi authored
      Don't use the switch to gf_rate_correction factor when
      temporal layers is used (i.e., cpi->oxcf.number_of_layers > 1).
      
      In temporal layers, we prefer to avoid this as any frame
      (e.g., base layer frame at anchor of pattern) may update
      both last and golden (and possibly alt-ref), and so we would get
      different rate correction factors within the same layer.
      
      This change will make sure one rate correction factor exists for each layer.
      
      Also, made some other code in qp-regulate that depends on
      alt/golden update specific to the 1 layer case.

      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.

      Entropy coding for hybrid transform · 3f5d60b3
      Deb Mukherjee authored
      Separates the entropy coding context models for 4x4, 8x8 and 16x16
      ADST variants.
      
      There is a small improvement for HD (hd/std-hd) by about 0.1-0.2%.
      Results on derf/yt are about the same, probably because there is not
      enough statistics.
      
      Results may improve somewhat once the initial probability tables are
      updated for the hybrid transforms which is coming soon.

      New motion vector entropy coding · 00f9eb65
      Deb Mukherjee authored
      Adds a new experiment with redesigned/refactored motion vector entropy
      coding. The patch also takes a first step towards separating the
      integer and fractional pel components of a MV. However the fractional
      pel encoding still depends on the integer pel part and so they are
      not fully independent. Further experiments are in progress to see
      how much they can be decoupled without affecting performance.
      All components including entropy coding/decoding, costing for MV
      search, forward updates and backward updates to probability tables,
      have been implemented.
      
      Results so far:
      derf: +0.19%
      std-hd: +0.28%
      yt: +0.80%
      hd: +1.15%

      derf: +0.284%
      std-hd: +0.289%
      yt: +0.849%
      hd: +1.254%

      hybrid transform of 16x16 dimension · de6dfa6b
      Jingning Han authored
      Enable ADST/DCT of dimension 16x16 for I16X16 modes. This change provides
      benefits mostly for hd sequences.
      
      Set up the framework for selectable transform dimension.
      
      Also allowing quantization parameter threshold to control the use
      of hybrid transform (This is currently disabled by setting threshold
      always above the quantization parameter. Adaptive thresholding can
      be built upon this, which will further improve the coding performance.)
      
      The coding performance gains (with respect to the codec that has all
      other configuration settings turned on) are
      
      derf:   0.013
      yt:     0.086
      hd:     0.198
      std-hd: 0.501

      Adds support for switchable interpolation filters. · 52597441
      Deb Mukherjee authored
      Allows for swtiching/setting interpolation filters at the MB
      level. A frame level flag indicates whether to use a specifc
      filter for the entire frame or to signal the interpolation
      filter for each MB. When switchable filters are used, the
      encoder chooses between 8-tap and 8-tap sharp filters. The
      code currently has options to explore other variations as well,
      which will be cleaned up subsequently.
      
      One issue with the framework is that encoding is slow. I
      tried to do some tricks to speed things up but it is still slow.
      Decoding speed should not be affected since the number of
      filter taps remain unchanged.
      
      With the current version, we are up 0.5% on derf on average but
      some videos city/mobile improve by close to 4 and 2% respectively.
      If we did a full-search by turning the SEARCH_BEST_FILTER flag
      on, the results are somewhat better.
      
      The framework can be combined with filtered prediction, and I
      seek feedback regarding that.
      
      Rebased.
