  • 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.

    AV1 encoders in libavif apparently now have access to autotiling as an option, which automatically sets the number of tiles in a frame based on frame area: https://github.com/AOMediaCodec/libavif/commit/ff322862b708e505349c9396fdcf7aaec9123f47

    The Alliance for Open Media's AVIF encoding and decoding library is also in a Github repo. Sharp, a Node module, has AVIF support. To make AVIF images, you can use avif.io, Squoosh, and the Squoosh command line tool aimed at supporting Node.js apps. GIMP and Paint.net support AVIF and there are Photoshop plugins. Mac has no plans to support AVIF, but you can easily install a codec plugin on Windows 10 for native support.
