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…
Sound like a Chrome/Youtube problem. My 2012 Macbook Pro plays 1080p AV1 just fine in VLC (pretty sure Youtube works fine too in Firefox, but I didn't check whether or not it was AV1 or H264).
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...
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…
Based on AV1's trajectory, hardware encode isn't necessary (though it is nice). The current encoder is a reference encoder. Now that the spec is finalized, expect significant speed improvements from production encoders (realtime likely won't happen until we get it in hardware though)
Hardware encode is required if you want things like video calls, camera recording and such to use it.
It isn’t required for content distribution platforms which aren’t realtime and the cost of encode is easily made up by hundreds of thousands of streams.

Does anyone know what is so costly to calculate in AV2?
In general they just increase the numbers on everything when they go up a generation.
e.g. if you check in 4 directions to see if you can reuse a chunk then make it check in 8 or 16.
Faster encoders will have smart heuristics on when to use these new abilities and when to skip them but the reference encoder will try everything in a dumb way to eke out a tiny win to maximize a theoretical advantage and map out the extreme best case.

use the enhanced h264-ify to block the av1 stream, av1 takes a lot of cpu
Last update seems to be "lawsuit was filed" with zero updates since then. That stuff tends to move slowly.
Hopefully their patents will be busted and preferably Dolby will be also forced to pay damages for filing invalid lawsuits. That's the only way to teach patent trolls proper lessons.

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

Why patents is a problem, please explain. If you build something that has been patented, then, well, you pay the per piece fee on it.
