Mostly a joke... I've been waiting for the AV1 Apple TV, so now I'm just waiting for AV2 support as Apple TV as well now.

My 10 year old iPhone 7 can play 1080p AV1 video in software for more than 200 minutes with VLC. The iPhone 7 was released a year and a half before AV1 was. So I think it's a safe bet the current Apple TV devices are capable of playing AV1 video in software. There's a VLC release for Apple TV: https://www.videolan.org/vlc/download-appletv.html https://apps.apple.com/us/app/vlc-media-player/id650377962?p...

Not especially relevant, as the obvious use of AV1 on the AppleTV is streaming, and the OS frameworks don't request AV1 without hardware decoding. Services which provide their own video decoding (are there any?) don't seem interested providing their own software decoder for the ATV, despite the bandwidth savings.

Six years ago Apple TV added support for playing 4K YouTube video:

YouTube's 4K videos are only available in VP9 and AV1.

So the YouTube app on tvOS has supported at least VP9 for six years and I wouldn't be surprised if it supports AV1 today.

And how long will it take before someone implements this standard and gets sued because Adobe or Dolby or whoever wanted to get slapped down? My knowledge may be out of date but if this is as "open" as AV1, I'm very skeptical that the individual companies will actually allow that. Greed and all that.

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.

What I'm interested in is seeing how this will improve the AVIF image format. AVIF stomps the competition for low-bitrate still images (where chroma subsampling is used). For lossless images, not so much. Lossless JPEG XL and lossless WEBP make lossless AVIF look like a joke.

Honestly AVIF2 is the last thing we need now. There are way too many minority image formats already.

I’m curious how much AV2 will actually help older hardware in practice. I’m on a 2019 Intel MacBook Pro: 2.6 GHz 6-core i7, 64 GB RAM. The machine is still more than powerful enough for normal desktop work and software dev, but YouTube in Chrome has become borderline unusable for me. My internet is fine, Safari plays the same videos smoothly, and YouTube “Stats for nerds” shows plenty of buffer but the decoding makes…

Unfortunately for you, newer codecs use more CPU than older ones so AV2 would probably be even worse.

This will always happen. There are just some entities that can't stand not seeking rent.

It may always happen but it would happen less if we updated patent laws to fine people who filed invalid patents or enforced some kind of similar punishment. If you file a patent, it's up to you to verify that your patent is actually valid, and the courts shouldn't have to do that legwork for you. It also doesn't help that the patent office/components of governments don't review patents as thoroughly as they used to.…

Even better, software patents should not be allowed in the first place.

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…

Does anyone know what is so costly to calculate in AV2?

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.
