Interesting discussion regarding the choice of entropy coder for AV1: https://encode.ru/threads/1890-Bench...ll=1#post56945

Daala range coder using 16 multiplications per symbol has won with rANS using 1 multiplication per symbol, and ~7x faster implementations: https://sites.google.com/site/powturbo/entropy-coder

Do anybody know why the slower and more costly one was chosen?

ps. This nibble adaptive rANS is e.g. used in recent open source Dropbox DivANS: https://blogs.dropbox.com/tech/2018/...r-with-divans/
