      Reduce memory footprint for CLPF decoding. · eb5794da
      Steinar Midtskogen authored
      Instead of having CLPF write to an entire new frame and
      copy the result back into the original frame, make the
      filter able to work in-place by keeping a buffer of size
      frame_width*filter_block_size and delay the write-back
      by one filter_block_size row.
      
      This reduces the cycles spent in the filter to ~75%.

      Bit accounting. · e6b12944
      Michael Bebenita authored
      This patch adds bit account infrastructure to the bit reader API.
      When configured with --enable-accounting, every bit reader API
      function records the number of bits necessary to decoding a symbol.
      Accounting symbol entries are collected in global accounting data
      structure, that can be used to understand exactly where bits are
      spent (http://aomanalyzer.org). The data structure is cleared and
      reused each frame to reduce memory usage. When configured without
      --enable-accounting, bit accounting does not incur any runtime
      overhead.
      
      All aom_read_xxx functions now have an additional string parameter
      that specifies the symbol name. By default, the ACCT_STR macro is
      used (which expands to __func__). For more precise accounting,
      these should be replaced with more descriptive names.

      Move palette code from libvpx/nextgenv2 to aomedia. · 764d1266
      Urvang Joshi authored
      Palette code originally by huisu@. Gives 11.68% BDRate improvement on
      screen content set.
      
      Last 7 small speedup patches from me, giving 10% speedup overall for
      screen content set.
      
      From aomedia/master:
      Revert 57fa6267 : Remove color_index_map
      
      From libvpx/nextgenv2:
      c93e5cc3 : Bring palette back to nextgenv2
      827e1b3f : Add test for screen content coding tools in end to end test
      78b0bd0a : Complete (mostly) migration of palette mode
      8a128c2a : Fixes for Palette mode
      4ab00912 : Palette mode: record selected transform type
      cbb8be76 : Set block size upper bound for Palette mode
      bb0e6921 : Convert palette from double to float.
      a0a23b7f : faster code: replace nested for loops by memcpy().
      016a5daa : Palette code: simpler and faster duplicate removal
      d0000208 : Palette code cleanup
      6dde8018 : Use built-in qsort(); create remove_dup() method.
      f746c103 : Handle centroid rounding inside palette.c itself.
      d68c7b6d : Palette: count Y colors only for screen content.
      f1906e96 : Palette code: remove the use of same if condition twice.
      
      Locally made sure all combinations of "--enable-ext-intra" and/or
      "--enable-palette" and/or "--enable-aom-highbitdepth" build OK.
      
      P.S. Note for future reference:
      EXT_INTRA experiment has only been moved *partially* to aomedia at this
      point. If and when the rest is moved to aomedia, EXT_INTRA + PALETTE
      combo needs to be moved to aomedia as well.

      Add decoder support for bi-direct prediction in EXT_REFS · e9147214
      Zoe Liu authored
      Following supports are added in the decoder:
      (1) Decoder support to show_existing_frame == 1;
      (2) Decoder support to avoid the referring to non-reference frames;
      (3) Decoder support to handle the case when cm->prev_frame gets retired
          in the reference buffer.
