I'm not a expert on video encoding

But i wonder if the future could depend less on fixed-function compression methods and more on AI networks that recreate the video but weight much less that a compressed video.

Neural codecs such as github.com/Orange-OpenSource/Cool-Chic

A few things - this is one step in a long, LONG path. AV2 is currently unusable in its current state (the encoder typically runs at around 1fps on good hardware), and likely will remain so til ~2028 when the first av2 hardware accelerated chips start dropping. Even then, I wouldn't expect AV2 streams to be common til 2030. IMO, if it were just the efficiency gains on the table (which are substantial - ~20-30% over AV…

Looking at how GPU development has been sidetracked for NPU, I worry that this is 2035 target at best. Manufacturers will push for maximising matrix operation silicon area. In the era of trillion dollar investments into datacenters, traffic cost is afterthought. The only benefitors might be YouTube, Netflix and such, but on their scale investment into ISP level caches might be cheaper.

so that new devices can adopt it They can't adopt it if it doesn't exist.

And what about old devices? I'm sure someone out there is still using an s5 as a daily driver... Future proofing is great and all, but 240p on modern devices looks like trash, even worse than tube tv.

They can keep using whatever they're currently using.

This doesn't take away anything. It's a new standard.

Based on your argument, one should add new safety standards to cars like seat belts, because old cars might not have them.

I generally don't like the current patent law but it sounds a bit off to pay the government & wait for them to review your patent claim and then get fined by the government when both of you were wrong about it. There are already processes to additionally fine a company bringing about a truly frivolous patent lawsuit, it's just rare because usually it's not so cut and dry as we'd like it to be.

I mean my idea isn't the only one in that solution space. My reasoning was to ensure that the government actually reviewed the patent and ensured it was valid instead of rubber stamping it. Or, even better, the filer of the patent application would do that. Although the best is probably to make software unpatentable anyway.

Yeah, I wouldn't mind getting rid of software patents. Or, at least, making the patent reviews more rigorous before assignment.

It took 7 years for the first patent assertion claim against AV1 to go to the courts and it will probably take a while for that case to resolve. Funnily enough, it wasn't from the pool constantly putting itself in the news about it over the years. I.e. it can take quite a while before attempts are made.

i'll be surprised if anything comes of it because like... https://aomedia.org/about/members/ if the legal departments of all these corporations haven't made them drop av1 in all these years there's probably not much there?

I'd like to think so as well (well, I don't know they'd necessarilymake them "drop" it as much as license those particular patents/accept the risk they may have to pay in the future) but on the other hand history has shown VP8 had a lot of companies behind it too before Google signed to sublicense patents from the MPEG LA & other holders for it.

> The biggest thing it does add though is multi-stream support

This was supported in H.264 MVC but only saw real use for 3D movies on physical BluRays. With almost no content available outside that.

In HW accelerated chips, what part of the calculations they usually accelerate? Could it be possible to repurpose old HW?

Typically things like quantization and motion estimation.

Congrats! How is the case of fighting off Dolby's patent racketeering going? They tried to attack Snapchat for using AV1.

Dolby's patents are garbage, and they know it. They managed to patent entropy coding somehow. This will not stand to challenges, and they managed to poke a well-resourced company.

Dav2d doesn't have the same nice ring to it. I hope there's someone with a decent repo-name punning skill who'll contribute before that. avi2ude? av2go?

daviid - or trim to davii and pronounce it "davey". But tbh I quite like dav2d.
