      Add experiment to restrict compressed header · 2eada612
      Debargha Mukherjee authored
      The compressed header is now used only when the refresh
      type is set as forward, i.e. in error resilience and
      frame parallel modes. As long as backward updates are
      used the header is disabled thereby saving bits.

      frame_superres: Post encode/decode upscaling · d2bcbb56
      Fergus Simpson authored
      This patch implements the post-encode and post-decode upscaling for the
      frame superresolution experiment to work.
      
      Upscaling happens after cdef and before loop restoration.
      
      For now, this patch forces on random-superres.
      
      The patch also cleans up some broken rate control hooks from VP9
      days, to be brought back later when the resize and superres tools
      are stable.

      Fix tree to cdf index mapping · 8e67c05f
      Jingning Han authored
      This fixes the mis-aligned cdf model derived from tree based
      model. It resolves the compression performance regression in
      dual filter, intra mode, inter mode, and transform block type
      coding, when ec-multisymbol is enabled by default.
      
      With dual filter enabled, the performance regression was 3.6%
      loss for lowres. This fix brings the performance gains back to 1%
      gains.

      Superframe index: Parse correct number of frame sizes · a414887a
      Adrian Grange authored
      If there are N frames in a superframe, the superframe
      index will enumerate the sizes of only the first
      (N - 1) frames. The code assumed that all N frame
      sizes are coded.
      
      The size of the final frame in the superframe is
      calculated as follows:
      (data_size - index_size - sum_of_N-1_frame_sizes)

      Fix compile with ext-tx · f541932b
      David Barker authored
      The switch to using daala_ec by default broke the compile
      when used with ext-tx, as some code which should have been
      inside #if !CONFIG_EXT_TX was not inside such a block.

      New experiment: Perceptual Vector Quantization from Daala · 77bba8d3
      Yushin Cho authored
      PVQ replaces the scalar quantizer and coefficient coding with a new
      design originally developed in Daala. It currently depends on the
      Daala entropy coder although it could be adapted to work with another
      entropy coder if needed:
      ./configure --enable-experimental --enable-daala_ec --enable-pvq
