Support AVIF

[GNURub]

I'd like to submit a proposal for a future feature to consider.

I've written pure-rust encoder: https://lib.rs/crates/cavif

And a decoder that uses libaom: https://lib.rs/crates/aom-decode

What's the binary size of the decoder and encoder?

cavif is pretty lean. I've replaced libavif with basically one big struct. It's 100% pure Rust. Includes rav1e. Executable is 1.7MB, gzips to 500KB.

aom-decode is fatter — 7MB — since it pulls in all of libaom. I haven't looked at trimming it down. Maybe dav1d would be smaller, but it needs meson and ninja to build, and I'm not a fan.

I'm hesitant to triple the size of Imageflow to add avif support.

I get that decoding brings in large dependencies, but you could support encoding only. Encoding can be done in pure Rust and rav1e is pretty lean. I've released my encoder as a library: https://docs.rs/ravif

[lilith]

I will consider it then.

Any progress on this? I would be very interested since AVIF support is at around 70% https://caniuse.com/avif and I believe it's really good.

I'm really hoping iOS adds support for AVIF. Safari gets much of its speed by delegating image processing to the OS and its incredible hardware integration, so stuff lands much more slowly there.

I would like to add this, but I have a lot going on right now, so I can't offer a timeline.

No problem - and thanks for your more-than-amazing work!

[stevetayloruk]

Support for this would be great with Safari soon to be supporting. https://www.coywolf.news/webmaster/safari-now-supports-avif-in-macos-ventura-and-ios-16/

@lilith AVIF support now?

[lilith]

It's planned. It will be slow, though, no getting around that.
