      MV entropy coding fixes and clean ups. · 62fcfab0
      Debargha Mukherjee authored
      Consistently uses cdfs for all mv symbols, and resolves
      some inconsistencies.
      
      All the legacy code dealing with probabilities and counts
      can now be removed.
      
      BDRATE (lowres 30 frames): -0.04% (a slight improvement).

      Remove CONFIG_CB4X4 config flags · 6ea917ec
      Debargha Mukherjee authored
      Since CB4X4 is adopted and without it the codec does not work,
      it is better to remove it and simplify the code.

      Add encoder/decoder pipeline to support single ref comp modes · 85b66463
      Zoe Liu authored
      Now the single ref comp mode should work with WEDGE and
      COMPOUND_SEGMENT. For motion_var, the OBMC_CAUSAL mode uses the 2nd
      predictor if the neighboring block is single ref comp mode predicted.
      
      This patch removes the mode of SR_NEAREST_NEWMV and leaves four
      single ref comp modes in total:
      
      SR_NEAREST_NEARMV
      SR_NEAR_NEWMV
      SR_ZERO_NEWMV
      SR_NEW_NEWMV

      intrabc: Add initial skeleton · 28744309
      Alex Converse authored
      Missing features:
      * RDOPT (Forced on for certain blocks)
      * Any form of border extension
      * Non MI sized right and bottom edges
      * MV prediction
      
      Present features:
      * Force intrabc for some blocks
      * Carry intrabc in the bitstream
      * Validate DV is causal
      * Reconstruct intrabc block assuming border extension is unnecessary

      Add options setting number of tile groups or MTU. · af6df175
      Thomas Davies authored
      Default MTU size is 0, which implies a fixed number
      of tile groups. MTU matching overrides fixed tile
      group. MTU matching will succeed unless a single
      tile is bigger than the MTU.
      
      --mtu-size is in bytes, and includes headers but
      not transport/wrapper overheads

      Add ec_multisymbol for common daala_ec and rans code · aca9feba
      Alex Converse authored
      The new ec_multisymbol experiment supersedes the rans experiment and is
      used for multisymbol features that can be backed by either daala_ec or
      rans.
      
      This experiment is automatically enabled by ec_adapt and will try to
      enable daala_ec or ans (in that order).

      Add EC_ADAPT experiment for symbol-adaptive entropy coding. · 9ac5508f
      Thomas authored
      This experiment performs symbol-by-symbol statistics
      adaptation for non-binary symbols. It requires DAALA_EC or
      RANS and ANS to be enabled. The adaptation is currently
      based on a simple recursive filter and is taken from
      Daala. It has an adaptation rate dependent on alphabet size,
      taken from Daala. It applies wherever non-binary symbols
      are encoded using Cumulative Probability Functions rather
      than trees.
      
      Where symbols are adapted, forward updates in the compressed
      header are removed.
      
      In the case of RANS coefficient token values are adapted,
      with the exception of the zero token which remains a
      binary symbol. In the case of DAALA_EC other values
      such as inter and intra modes are adapted as CDFs are
      provided in those cases.
      
      The experiment is configured with:
      
      ./configure --enable-experimental --enable-daala-ec --enable-ec-adapt
      
      or
      
      ./configure --enable-experimental --enable-ans --enable-rans \
          --enable-ec-adapt
      
      EC_ADAPT is not currently compatible with tiles.
      
      BDR results on Objective-1-fast give a small loss:
      
      PSNR YCbCr:      0.51%      0.49%      0.48%
      PSNRHVS:      0.50%

      Encode and decode multiple tile groups · 80188d15
      Thomas Davies authored
      This is a manual adaptation of the following commit from aom/master:
      ce12003d
      
      The original commit message:
      
      A tile group is a set of tiles in scan order.
      
      Each tile group has a version of uncompressed and compressed headers,
      identical apart from tile group parameters.
      Encoding probability updates takes account of the number of
      headers to control overheads.
      
      The decoder supports arbitrary numbers of tile groups with
      arbitrary number of tiles. The number of tiles in a TG is
      signalled in the uncompressed header for that TG.
      
      The encoder currently only supports a fixed number
      of TGs (3, when error resilient mode is on) of equal size
      (except possibly for the last one).
      
      The average BDR performnce with 3 tile groups versus
      anchor with error resilient mode and up to 16 tiles is:
      
      NR YCbCr:      3.02%      3.04%      3.05%
      PSNRHVS:      3.09%
      SSIM:      3.06%
      MSSSIM:      3.05%
      CIEDE2000:      3.04%
