I can't find the post now, but one of the RAD developers behind this codec (it's their 3rd ANS based codec I believe) has said that they would likely be willing to open source their ANS family for a one-time payment of iirc around $5 million. No need for the entire RAD stack.
- brigade 10y agoOops, his ballpark was $50 million. I obviously have no idea how much things cost. Still, I think many of the key ideas behind Kraken are out there and not patented. Zstd and lzfse already use ANS variants, for instance. But they're targeting different speed/compression tradeoffs, and aren't implemented as well as Kraken.
