Is there any consumer-level hardware available that supports AV1 encoding yet?
Intel meteor lake chips support AV1 encode/decode.

AV1 competes with h266. They were released near the same date. In many ways h266 has already lost the battle as nobody supports it even though it's been around just as long as AV1. h267 is still in development and due to be released in 2028. That's the actual competitor with AV2.
I guess it depends how you looked at it. Performance-wise AV1 seems more similar to h265. Hardware support wise h266 seems to have only had shipping hardware this year? So I guess neither of these line up 1:1. I tend to see h265 and AV1 competing pretty hard right now so I tend to think of those as one generation and presumably h266 and AV2 will compete as the next generation.
The way MPEG runs things there are some oddness with the likes of H265. MPEG likes to add little extensions to a codec over time. That's why H265 was first released in 2013 but ultimately had like 10 different extensions after that fact (the last one in 2024).
AV1 and VP9/VP8 before that have, in contrast, been pretty much static after they were released. AV1 has had a single errata after it's release.
So I could see why you'd see H265 as the competitor. I mostly don't simply because I believe they explicitly stated that they were trying to be competitive with 266.
I personally prefer the way AOMedia is running things and I suspect hardware manufacturers do as well. No licenses and AOM is creating open source reference encoders/decoders. They are working very hard to make it easy for manufacturers to be able to pick up the spec and run with it. Keeping the stream standard static for a long period also means manufacturers don't have to worry that they won't get a new extension next year. Content encoders are also reasonably guaranteed that their encoding with today's software still works with yesteryear hardware.
MPEG, on the other hand, is paywalling the crap out of everything.

#43Is this intended to be competitive with h.266/VVC? And is it?
AV1 competes with VVC. AV2 will be competitive with h.267
In terms of pure compression ratio AV1 compete mostly with h265/HVEC in most cases. It does perform pretty well for low bitrate and specific situation like synthetic noise, but h265 is usually better for higher bitrate situations. Hopefully, AV2 will be able to compete with the future H267.
But to be honest, video codec have gotten so good these days, I just hope that we get a reasonably fast open-source encoder. AV1 and HVEC can already turn a 50Go bluray into an almost visually lossless 5~3Go file.

h266 (aka VVC) is seemingly ~~late in development~~ (edit: It has been released but doesn't have much hardware uptake yet). They probably want to ensure that people are aware that it will be matched so that they don't commit to it and AV2 ends up a bit late to the party like AV1 is compared to h265 where it had a notable compatibility lead. If people know that AV2 is coming and competitive they may avoid adopting h26…

VVC isn't being considered for the internet by any western companies, but it's already gotten significant adoption by the Chinese companies that developed it.

#45Anyone use AV1? How good is it? What are your thoughts on AV2?
In my experience (not professional, encoding various files for archiving or sharing), AV1 perform quite well for low bitrate situation/streaming, and the encoder is reasonably fast (not as fast as h264 ofc, but that's decades of work on it).
But for higher quality encoding, I personally found that h265/HVEC almost always beat it, with similar encoding time.
As for AV2, I just hope that we get a good open-source encoder.

#46"AV1 adoption is accelerating" But before it is widely used and accepted, here's AV2 for you to have compatibility issues with in the wild With the ubiquity of h.264 and the patents expiring, will anyone but streamers care?
I understand the point you're trying to make, but I think I can at least sort of understand why they're going with this speed of release cadence. If the release cadence is too slow, you might end up with another JPEG situation where the new codec is undeniably better in every way, but nobody wants to implement it since the old standard was around for so long without any competition.

That's a weird pull. AFAIK the MPEG group is international. Broadcom, AFAIK, is the biggest pusher of VVC and they are American.

> If the release cadence is too slow...
Another reason to get a new video codec standard finalized sooner is that hardware implementation and deployment in mass market consumer SOCs is glacially slow. On the software side, encoder and decoder performance tends to improve meaningfully in the first few years as optimization occurs. And those running large media distribution platforms prefer at least 12-18 months to evaluate and implement a new codec.

Anyone can participate, yes. For H.266, many of the big H.265 contributors didn't participate as much while Huawei, Tencent, Bytedance, Alibaba, etc. stepped up their contributions significantly. The bulk of the new coding tools were developed by them I believe.
