      Add config flags and macros to control ext-inter · 37f6fe61
      Debargha Mukherjee authored
      Adds a dependent config flag 'interintra' to turn on/off interintra
      modes altogether.
      Adds a dependent config flag 'wedge' to turn on/off wedge compound
      for both interinter and interintra.
      
      Adds another macro to change wedge predictors to use
      only 0, 1/2, or 1 weights.
      
      From now, use
      --enable-ext-inter --enable-wedge --enable-interintra to get the
      same behavior as the old --enable-ext-inter.

      frame_superres: Add experimental flag · 6ee201db
      Fergus Simpson authored
      Frame Super-Resolution is an experiment currently under development.
      This commit just adds an experimental flag for it.
      
      The goal of the experiment is to compress a downsampled version of a
      frame instead of the full resolution one when bandwidth is limited. The
      decoder will need to upsample and filter the frame it recieves after
      decoding. It is thought that this will result in a visually superior
      result in low bandwidth scenarios.

      Port Daala stream analyzer to AV1. · f4fa01e9
      Nathan E. Egge authored
      This ports the wx-widgets stream analyzer from Daala to AV1.
      Currently, this supports playback, zooming, and printing bit accounting
       statistics to stdout.
      The configure script does not yet build the analyzer, to compile it:
       g++ -I. examples/analyzer.cc video_reader.c ivfdec.c tools_common.c \
       libaom.a `wx-config --cppflags` `wx-config --libs` -o analyzer

      improving palette throughput · 33bcd117
      Fangwen Fu authored
      * code the palette color index using 45 wavefront
      * interleave the coeff and palette color index in
        transform block level
      * the above change does not change code efficiency
      
      Details: 
      The 45 wavefront scan allows to compute the ctx of
      the diagonal samples' indices  at the same time. 
      Interleaving palette indices and palette residual
      on a transform block basis means that the entropy
       decoding and further processing of the palette 
      residual is not delayed by the entropy decoding 
      of all the color indices of the palette encoded 
      block.

      This allows compiling a codec using the same operating path (the generic
      "high-bitdepth" one), regardless of the profile of the input bitstream.
      For now, keep the 16-bit (generic) pixel operating path disabled by default.

      Implement a new rate control system · 002e7b7a
      Rostislav Pehlivanov authored
      This commit implements a new rate control system which was ported from
      Daala's rate control system (which was based off of Theora's rate
      control system) to the encoder. Its aim is to address the weaknesses of
      the current rate control system and eventually serve as its replacement.
      
      This is still work in progress. So far this commit only implements
      support for single pass encoding for constant quality and bitrate
      targeting.
      Additional commits which implement two-pass support and the rest to
      match the feature set of the current rate control system are coming
      soon.
      
      The rate control system hasn't been fully tuned (and will likely need
      additional tuning as the encoder's development progresses) and does
      contain some "hacks", to convert the quality to a quantizer value
      (empirical) and to tweak the quantizer in between golden frames (which
      uses some code from the current rate control system as well as code
      which attempts to model what that code does), the latter of which is
      only in the constant quality codepath.
      
      Bitrate targeting works much better than the current rate control
      system's targeting and will actually closely match the rate specified by
      the user without the current rate control system's bursty behaviour.

      Add a new experiment of REF_ADAPT · b05e5d10
      Zoe Liu authored
      Noticed that some ALTREF_FRAMEs could have used compound modes for its
      prediction but have been labeled as SINGLE_REFERENCE mode in the frame
      header. This experiment is to remove the COMPOUND_REFERENCE mode from
      the frame-level reference mode choices and only leave SINGLE_REFERENCE
      and REFERENCE_MODE_SELECT the two choices in the frame header.
      
      When turning on both ext-refs and ref-adapt, compared against ext-refs
      itself, a small gain is achieved. In PSNR, the bitrate saving gains are
      as follows:
      
      lowres: Avg -0.120%; BDRate -0.128%
      midres: Avg -0.155%; BDRate -0.128%
