      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
      
      The version of PVQ in this commit is adapted from the following
      revision of Daala:
      https://github.com/xiph/daala/commit/fb51c1ade6a31b668a0157d89de8f0a4493162a8

      - https://jmvalin.ca/papers/spie_pvq.pdf
      
      The following files are copied as-is from Daala with minimal
      adaptations, therefore we disable clang-format on those files
      to make it easier to synchronize the AV1 and Daala codebases in the future:

      Known issues:
      - Lossless mode is not supported, '--lossless=1' will give the same result as
      '--end-usage=q --cq-level=1'.
      - High bit depth is not supported by PVQ.
