It’s proprietary and requires you or the project that wants to use it to buy a license. That’s why the codec coast money on Windows and also why most browsers don’t support it and never will.
Oh, I wasn’t aware, can you tell me in what way, for AOM it’s about patenting parts of the codec that have been developed by its participants, what about them?
But does it have the same virality of AV1 is what I’m asking?
AV1 implementations are open source, but you might have your licence revoked by AOM making it effectively a timed bomb, since it could happen at any moment, in the worst case when AV1 is everywhere. Also it makes building on top of it a legal risk because AOM still holds the patents, I say risk because you may live in a country that doesn’t give a crap about software patents, so you would be safe to a certain extent
It is both as you say, but the problem lies in its patents that are basically against development of competing codecs, so it holds back innovation in the name of keeping Google and the other collaborating big tech companies at the top.
That doesn’t take away any of its great technical merits, it’s just that it is quite unethical
I’m not a lawyer, but after some reading, my understanding is that the reason they are patenting and then releasing a patent license (https://aomedia.org/license/patent-license/), is actually to try and avoid patent litigation.
If a member from the AOM group (which includes Google but also several more giants) tries to litigate over one of the patents they have under the AOM patent license, then my understanding is that that member loses the rights to use the patents from the other members which are also submitted to the AOM and using the same patent license. So it’s a way to have some warranties that one of the members won’t go haywire and start using the patents to sue people over what they consider their “property”.
But as I said, I’m not an expert on this. So do let me know if I’m wrong.
My impression is that simply “not patenting” something is not enough to ensure that you are protected from it being patented in the future. In fact, we cannot even know how many “unknown” patents might be within any particular standard… so actually having patents on it that are backed by big players that other patent trolls might be afraid of upsetting is the only way to have some assurance that at least there’s some amount of protection. That, or waiting ~20 years for all possible patents to expire.
Oh gosh, I think you’re actually right, I thought that JXL didn’t have any such restrictions, but those have been put in place by none other than Google, I look like fool now don’t I? Lol
There is still something that I fail to understand then, what is the real reason why Google scrapped JXL support from Chromium if it wasn’t to boost AVIF? To further complicate the matter, on the Wikipedia page there is mention of patent concerns only on AV1 (and consequently AVIF) and not on JXL. I was basing my arguments on the links I posted alongside the image, but I guess my research was incomplete
Still better than HEVC in many ways
can you tell me whats wrong with hevc? im ignorant and many of my videos use this
It’s proprietary and requires you or the project that wants to use it to buy a license. That’s why the codec coast money on Windows and also why most browsers don’t support it and never will.
Also AV1 is just superior in every way.
thank you
Absolutely true, but let’s just say that setting up the conditions to stifle the competition isn’t very nice of them
You could say the same about HEVC
Oh, I wasn’t aware, can you tell me in what way, for AOM it’s about patenting parts of the codec that have been developed by its participants, what about them?
HEVC is also a patended codec. Also it’s proprietary too and they’re even more closed than AV1
But does it have the same virality of AV1 is what I’m asking?

Is AV1 closed?
I ask it as a genuine question, I’m not saying that you are wrong, but I thought it was open & royalty-free.

In fact, it looks like even JPEG-XL is encumbered with Google patents apparently: https://github.com/ImageMagick/jpeg-xl/blob/main/PATENTS

It’s royalty-free and closed. So it’s free to use but it’s not free as in you have the freedom to do with it whatever you want.
