The way things are going, we can pretty much forget about AV2 hardware encoders in PCs anytime soon. All the newest, best chip capacity is being completely hogged by Apple and AI companies. Unless chipmakers port the AV2 design to older, cheaper nodes, it’s just not happening for average users. We’ll probably see some Chinese TV chip makers throw in an AV2 decoder just to check a box, but as an actual encoder? I woul…

I wouldn't be so pessimistic, Intel and AMD aren't going to stop making CPUs, and if their integrated graphics adds AV2 it will be motivation enough for others to follow.

Ram and Ssd is just the start capitalism dictates profits will suck all production to AI. CPu have 3-5 year production timeline ie cpu prices will start going up a lot more as previous production contracts expire you might even get shortages new consumer cpus won't be affordable or spread as fast as you think.

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

It will probably depend on whether NPUs are universally available in smartphones, and whether we get a standard API for accessing NPUs. But I don't know whether AI-based codecs can have battery usage competitive with fixed-function hardware.

Agreed, unless AI progress slows down enough that it becomes reasonable to bake weights into circuitry, the conventional approach will probably remain preferable for encoding, at least on power constrained devices.

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…

I gave up using Chrome a decade ago. It’s a power sucking pig. Safari has its own issues, but at least it’s usable. When I need something that isn’t Safari, I use Firefox.

Chrome has used less power than Safari for a few years now. As far as I know, the only good reason to use Safari is to use FairPlay DRM for sites that need it. For all other purposes, Firefox or Chrome is superior. https://birchtree.me/blog/everyone-says-chrome-devastates-ma...

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)

I strongly disagree with it not being required. I run a small social news site - AV1 is still prohibatively expensive both for the server and clients for software encoding/decoding. Without hardware encoding, the tradeoff for better compression ratios in exchange for massive battery use + very long processing times for encoding simply isn't worth it. In order to get AV1 out, I have to often process a h264 version of a video first anyway, just so the client isn't left waiting for their video upload to finish encoding. This means to support AV1 I'm not saving anything on the storage side. Even youtube only does AV1 encodes for extremely popular videos - it only makes sense to do at significant scale.

I love AV1, don't get me wrong, and I can't wait til I can switch over to it as a single unified format for both images and video, but for now the cost is too high until hardware acceleration becomes ubiquitous

Interesting, thanks. I’ll give it another try. It certainly used to be a pig. I remember times when the fan on my MacBook sounded like a freaking hovercraft and you’d go into system monitor and see a Chrome process just sucking down every CPU cycle. You’d quit Chrome and the fans would spin down and stop. But if they’ve fixed that, maybe it’s worth another go.

Safari has a terrible developer experience and has been behind in implementing the various browser API for years, including AV1 support.

Like I said, Safari has its own issues. But huge power consumption isn’t one of them.

Is there an AV1 2.0? I'm not using this codec if they can't do basic semantic versioning right.

Codecs are final (the only exception being H.265 with a couple of later additions/extensions that required new codec IP and were not that widely deployed or supported). They are not software. You cannot have upgrades for fixed function HW decoders (which is a must for pretty much any established codec and AV2 will be also one of them).

Neat but the real world still, and for decades to come - lives on h264 https://www.wink.co/documentation/Why-H264-Is-Almost-Always-...

Did you read what you shared? It’s talking about security cameras, low-bitrate video. FTA: "Myth Busted: At security camera bitrates (400-800 Kbps), H.265 provides negligible compression benefits. The marketing claims of "50% savings" apply only to high-bitrate content like 4K movies at 25+ Mbps, not security cameras."

That's also bullshit anyway. Not surprising because the article is slop.
