Let's see what browsers/apps actually support animated JPEG-XL files! And in case it isn't working for you, here is a still shot from this animation, in a widely-supported format:
Also, I could not find a reputable source to explain exactly what the X in JPEG-XL actually stands for, so I just went with "extensible", a la XML.
Voyager Android app doesn't seem to work
On Android, it is not rendering in Thunder or any of the various Firefox/Chromium forks that I have installed. When I tap on it, instead of displaying in-app, it just tries to download the file. When I open that local file in Simple Gallery, it displays as just a static image of the first frame of the animation (but doesn't actually actually play the animation). No other app that I have installed opens the file at all.
On Linux, I have the same experience with browsers just downloading the file instead of actually rendering it. Opening the local file in Gwenview does play back the full animation as expected.
I'm running Bazzite on my main desktop, and have various Firefox derivatives installed. It only offers to download the image. The default Gnome Image Viewer shows it as a still image. I can view it animated with:
ffplay -loop 0 80ottu.jxl
Edit: I installed Ungoogled Chromium as a test as well and it also only offers to download the image.
VLC on Android/Linux does not work at all. MPV on Android also does not, but it does work fine on Linux. Granted MPV does not automatically loop the animation, which probably isn't really an issue. I think MPV is a video player first and foremost, so it makes sense that it would treat animated images the same as it treats videos (i.e. not loop by default, and only do so if you have repeat mode set appropriately).
About the XL,
The name refers to the design committee (JPEG), the X designates the series of its image coding standards published since 2000 (XT,XR,XS), and L stands for "long-term", highlighting the intent to create a future-proof, long-lived format to succeed JPEG/JFIF.
Right, but what word does it actually stand for?
iOS Safari/Photos will render the first frame of the JXL, but not play the animation.
The answer is unfortunately almost nothing. Safari should MAYBE support it a bit. Current release versions of Firefox and Chrome don't even support static jxl out of the box. Though static can be enabled in release versions of Firefox, possibly chrome too. But not automatically enabled in both. They really need to get hopping on this. JXL is pretty great generally. And gif really does need replacing. Though I'm not sure mp4 with something like av1 or h264 wouldn't be as good or better for animation.
It doesn’t work in Chromium at all, only in forks that hack it back in like Thorium.
Firefox needs a flag enabled in about:config, yes.
…And yeah. Realistically, a low framerate AV1 (or AVC) webm is more optimal for this, better supported, and will perform better on a lot of hardware. TBH JXL should drop the animation stuff and focus on static images (which it’s incredible at) and HDR support.
Yes Google has really been the biggest one fighting against jxl. Mozilla has flirted with it a lot. Mostly dropping it because of the perceived peer pressure.
Yeah, it’s ridiculous.
All the AI stuff they’re shipping in Chrome, and the concern with JXL is security/attack surface? That’s a total lie. It’s so much better than AVIF for certain niches, and it’s already supported by Apple.
