Hey there. I'm having some problems with AVIF files on iOS 16. If you're reading
this from an iPhone running iOS 16 you may see the problem.
I recently started using a new program called
[uploud](https://github.com/Xe/x/blob/master/cmd/uploud/main.go) to automate
converting and uploading things like my hero images and slides to [Backblaze
B2](https://www.backblaze.com/b2/cloud-storage.html), my storage provider.
However, images that I make with
[`github.com/Kagami/go-avif`](https://github.com/Kagami/go-avif) won't load on
iOS 16 Safari. Here are the encoding settings I am using:
```go
&avif.Options{
Threads: runtime.GOMAXPROCS(0),
Speed: 0,
Quality: 48,
}
```
This creates images that can be viewed in Chrome:
But not on iOS 16:
What am I doing wrong? I get no useful debug information from the browser
inspector on Safari. It just says the image is _wrong_ but won't tell me _why_.
Please [contact me](https://xeiaso.net/contact) if you have any ideas.
