That’s still not patent free. Heck it’s right there: “irrevocable (unless we say so)”.

It does, yes, but from what I gather it’s rather difficult to actually encode such an animated image compared to, say, a GIF. Display should work just fine.

A file format can not, by itself, be “incompatible” with a website. What matters is the browser, and Firefox at least is adding support (slowly), and they are the ones who matter ATM.

Open is not the same as patent-free, the two things can coexist (and they do in the case of webp).

It’s open to write the code, but in order to be authorized to use it you have to get a permit from Google. You can’t eg.: fork from Firefox and use their permit (as you implicitly could with patent-free). Plus, Google can rescind their patent grant at any point, which they are bound to do once they secure ownership of the internet.

That’s good to know! If I ever get to make an instance of anything in the Fediverse and I set it to save images (lol, fat chace), I’m setting it to either JPEG-XL or XPM.

AV1 is for video though? JPEG-XL is patent-free, better performant than most or all alternatives, and made for images.

These are factors webp was designed for.

I thought it was designed so that Google could continue to de-facto own the web.

JPEG-XL exists, is factually better, and is not patent encumbered.

Even better if it can be run on Podman, since you won’t need a potential root access and hook to set up the containers in the first place, and UID mapping on podman rootless will pretty much guarantee that the user IDs the process gets are not mapped to any real user in your system.
