CVE-2023-4863: Heap buffer overflow in WebP (Chrome)
It's 2023, surely this is not yet another bug related to memory unsafety that could be avoided if we'd stop writing critical code that deals with extremely complex untrusted input (media codecs) in memory unsafe languages?
Yep, of course it is: https://github.com/webmproject/libwebp/commit/902bc919033134...
I guess libwebp could be excused as it was started when there were no alternatives, but even for new projects today we're still committing the same mistake[1][2][3].

[2] -- https://github.com/AOMediaCodec/libavif
[3] -- https://github.com/AOMediaCodec/libiamf
Yep. Keep writing these in C; surely nothing will go wrong.

Is there any clear documentation on how to make avif collections and how to read them?
As far as I understand you are talking about this plugin. I don't know c++ and half of the code was like a black magic, but if I get it correctly, it encodes your images with libavif, and adds custom metadata ([solar/time of day] -> json -> base64).

FSF Slams Google over Dropping JPEG-XL in Chrome
So a few dozen comments, but so far it doesn't look like any mention the immediate thing that jumped out at me which was the claims vs AVIF:
>"In turn, what users will be given is yet another facet of the web that Google itself controls: the AVIF format."
Huh? I'll admit I haven't been following codecs as super ultra closely as I used to, but I thought AOM was a pretty broad coalition of varying interests and AV1 an open, royalty free codec that was plenty open source friendly? I've heard plenty of reasonable arguments that JPEG XL has some real technical advantages over AVIF and as well as superior performance is much more feature rich and scalable. So I could see people being bummed for that. But this is the first time I've heard the assertion that it's somehow a Google project? I mean, AOM's libavif reference is BSD too [0]? I'd love some more details on that from anyone who has been following this more closely. I can even understand if AOM isn't as community friendly and an accusation that it's dominated by big corps, but in that case why single out Google alone? From wiki:
>The governing members of the Alliance for Open Media are Amazon, Apple, ARM, Cisco, Facebook, Google, Huawei, Intel, Microsoft, Mozilla, Netflix, Nvidia, Samsung Electronics and Tencent.
Like, Google is certainly significant, but that's a lot of equally heavy hitters. And interesting that Mozilla is there too.

JPEG XL support has officially been removed from Chromium
> You have a good point that AVIF layered image items can act like such P/B-frames. Do libavif (or other AVIF implementations if any) make use of them?
Seemingly. As search for "libavif progressive encoding" shows several issues about this, and a search for "progressive" in https://github.com/AOMediaCodec/libavif/blob/main/include/av... shows an enum for avifProgressiveState, appears to show support for it.

Animated AVIF and JXL tools for Windows
Apart from mpv and ffplay, the only software I currently have installed that can play animated AVIF is Chromium. And from what I've read from this libavif bug report, I'm not sure if looping animated files in general is something that's just done by default by a lot of software regardless of whether the file is marked as a loop or not.

How to create progressive AVIF images?
The support for progressive AVIF decoding has landed in libavif and in Chromium. But are there any docs on how to create and test progressive AVIF images?
-
The Case for JPEG XL
The "for example" is the key here, because AVIF does support multi-layer coding per the spec now (though not currently implemented in libavif from what I can tell).

What libaom options are relevant to avif encoding with libavif?
If you want to try something using rav1e, you could try cavif-rs. rav1e by default does quite well with still images, which is nice: https://github.com/kornelski/cavif-rs
What are some alternatives?
rav1e - The fastest and safest AV1 encoder.
jxl-winthumb - A JPEG XL (*.jxl) thumbnail handler for Windows File Explorer.
av1-avif - AV1 Image File Format Specification - ISO-BMFF/HEIF derivative
