Where’s the pressure? Who’s making these files and trying to use them?

The standards bodies and the companies that pay their bills. That’s Netflix, Google, et al. All have a vested interest in good multimedia support in browsers. It’s why browsers have shockingly good support actually, most of the problems are downstream on clients and implementations that don’t know or care to enable these newer formats.

What am I supposed to do?

You decide what to target, and work with what you have. That’s how it’s always been with web technology.

If you need to support the barest minimal possible clients then you might not even have HTML5. Otherwise, if you have HTML5 you can use the source tag to provide clients with a choice of formats/encodings and they can pick the one they support. If the clients can’t even mange that, well, things on the internet have always been broken anyway.

And somebody’s gotta start somewhere, WebP was shoved down everyones’ throats and now it’s supported very broadly, as AVIF pick up users software devs will take notice and start supporting it.

Using a browser or third party app?

I think that’s a reasonable way to look at it.

It’s not the route I’d take, after all, the video tag in html supports specifying multiple sources (including different formats/encodings), and with full control of the stack (they vend Safari) you could have logic on devices without AV1 hardware that prefers the AVC/HEVC/VP9 sources instead — then fallback to AV1 SW if it’s the only option. That seems a better user experience than just failing to display content.

Very interesting, thank you!

I checked that app’s source code, and basically they’re doing their own avif decode call instead of relying on a browser/webview to handle it. So essentially they forgot/don’t know/don’t intend to implement animated avif. Looks like they also use the aom reference decoder instead of using something faster like dav1d.

That’s caused by bad regex in the app, it’s getting confused about domains.

e: attempted fix by using an aliased domain.

It’s an intentional behavior by Apple. Basically they just don’t support AV1 videostreams unless the hardware you’re using has a hardware decoder (read: very new). They could support it using software decode (what browsers typically do for AV1 inside avif containers) but… for whatever reasons don’t.

Apple has limited support for AV1 streams (yes, even for software decode) unless on very recent hardware. Here’s an AV1 stream inside a webm container for comparison, would be interesting to see if that works over the avif container on your stack.

Can just use avif instead, it holds an AV1 stream and acts like gifs/images do WRT looping — also very broad support (more than AV1 in WebM containers).

Demonstration:

Edit: switched to an example with simpler decode requirements.

They do disclose it, it’s part of the paperwork when you purchase the vehicle.

Of course the dealers make it very easy to “opt-in” by accident.

The fact that it’s out in the open, literally on the car manufacturer sites, but people still deny this behavior, is a grim omen.

They sell driving habits and other informatics to insurance companies at the very least, this is publicly known.

Hiding? Modern vehicles straight up have cell modems and advertise it, look up Toyota Connected Services for example.

It’s a different world, there isn’t much driving VVC like there was for AVC and HEVC. There isn’t a new physical media format, and even the latest OTA TV specification is stuck on HEVC.

It’s going to be up to streaming platforms what wins the next codec race, and a lot of them are betting on AV1 and AV2 for obvious reasons. I don’t see VVC really getting widespread adoption.

The biggest concern I have for these crackdowns is how uncalibrated the exams and material now are. When a significant portion of the student body cheats, the exam difficulties are pushed up, and the study/teaching material gets worse in quality.

The result is anyone not cheating is put at a disadvantage, and if you roll this out suddenly across the classes, you’re probably gonna fail a bunch of people.
