Indeed, VP* codecs (Webm etc, from On2 acquisition) avoid arithmetic coding like the plague due to patents.

- astrange 11y agoHmm, I think the range coder used in VPx is basically just an arithmetic coder with the labels changed. It's not any less efficient. Also, JPEG and LZMA have arithmetic coders with no current patent claims. CABAC just has specific patents. CABAC is not good on CPUs anyway - it's only fast on hardware due to using lookup tables in the critical path.
