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.

If you're going to do that, then the new thing must be so much better than the old thing that makes the pain of switching to the new thing worth while.
By the time h.265 encoding was trying to gain traction, h.264 encoding speeds were very fast. The image improvement was negligible with the main benefit being smaller file sizes. For the average user, the increased encoding times did not justify that. The switch from MPEG-2 to h.264 had very noticeable quality improvements so it did make it worth while for the slower encodes until h.264 was locked and key code included in CPUs. It was similar to the adoption rates of DVD from VHS compared to Blu-ray from DVD.

That's a contradiction because quality improvement and file size improvement are just two sides of the same coin. You can't have a large quality improvement at the same bit rate without having a large file size reduction at the same quality.

I do. I watch scifi shows over the internet with my friends. We watch it together on a web page with an html5 video element served out of my apartment. I've had to re-encode it to 3 megabits per second (to avoid stutter/buffering) with no b-frames. When initially setting it up, I tested both H264 and AV1 at that bitrate and H264 looked considerably worse. No surprise there, considering H264 is old enough to drink (22 years) whereas AV1 is only 7 years old.

Is this intended to be competitive with h.266/VVC? And is it?

> Is this intended to be competitive with h.266/VVC? And is it?
Yes:
> VVC is not alone in the video coding race. AV1, backed by AOMedia, has already gained traction, although its performance does not make it a direct competitor to VVC in high-end applications. The upcoming AV2, as well as AI-driven encoding techniques, could pose challenges to VVC’s success. Nevertheless, VVC’s strong technical foundation, industry support, and clear intellectual property structure position it as a promising long-term solution for video coding.
> For businesses focused on reducing operational costs, this is a key point in the h.266 vs av1 debate. While the H.266/VVC codec offers powerful compression improvements over h.265, AV1—and eventually AV2—may be more attractive thanks to simpler licensing and long-term affordability.
Anyone use AV1? How good is it? What are your thoughts on AV2?

AV1 is really one of those things born out of internet providers (e.g. Google, Amazon) put together so they can deliver content more efficiently with their bandwidth without needing to deal with a complicated web of royalties in addition to paying said royalties. There's plenty of people using AV1 or it's image format but don't realize it.
Also, video encoding pretty much always comes with the tradeoff of more efficient = uses more processing power

I did some testing with the 3 main AV1 encoders with gifs (avif). They’re pretty good. But not as good as jpeg xl but currently basically only Safari supports it.
For most “normie” use cases, I’d recommend cloudflares image transforms which are available on free tier. I actually wrote a small Jekyll plugin for my site to auto prefix images with their transform. Idk why but shipping optimized images is just one of those things that tickles me!
I implemented an encoding pipeline for AV1 for vids uploaded to my social news site (think reddit competitor except I'm extremely small fry). I eventually removed the code for it.
While the space savings and quality improvements are good, the encoding speed is an order of magnitude slower than using h264/vp9. In the end the user experience of causing people to wait significantly longer for an AV1 encode wasn't worth the tradeoff. To fix the user experience problem, I still had to encode a h264 version anyway, which kinda defeats the point when it comes to space savings. You still get data transfer improvements, but the break even point for when the encoding costs offset the data transfer costs were around 1000 views per min of video encoded, and as an average I'm far below that.
IMO there's a reason why YouTube only encodes AV1 for certain videos - I suspect it's based off of a view count. Past that point they trigger a AV1 encode, but it isn't worth it to do all videos, at least right now.
Worth keeping in mind I was looking at this ~2 years ago, so things may have evolved since then.

I manually turn AV1 off on my android phone. It uses more battery and won't sustain 1440p at 1.5x speed up without the odd frameskip.

Lots of people are using AV1. They just don't know it.

SVT-AV1 is the fastest software encoder for pretty much any level of quality you would want.
