Hey, just wanted to shamelessly plug a recent project of mine, a freestanding QOI encoder in Zig: https://github.com/gianni-rosato/qoi-enc-zig

I must say, I really like the QOI image codec despite its shortcomings for coding efficiency and flexibility - it is dead simple, easy to implement, and super effective for what it is! I'd be happy in a world where we used QOI instead of PNG for a lot of stuff. And I've already fallen in love with Zig, which I think is very easy :)

"... Interop 2024 omits JPEG XL, the most popular proposal as measured by community reactions (emojis added to proposal discussion threads). JPEG XL garnered 646 reactions, more than four times more than the second place finisher, which also wasn't included."

An unfortunate conclusion from a clearly biased group that is supposed to be unbiased. Unfortunate, unclear decision making from Interop this year.

Apparently the #samsung Galaxy S24's "downloadable" Gallery app (not sure what this means) supports JPEG-XL compression in RAW images!

> Downlodable App
> 1. Expert RAW
> The basic resolution has been improved from 12MP to 24MP, and image quality and tone in low light have been improved through nightography technology collaboration.
> In addition, Digital ND filter, which was supported as beta in previous S23, is officially provided and Auto mode is provided for user convenience.
> Additionally, storage capacity has been reduced while maintaining image quality by providing JPEG XL format.

Again, not super well-versed in what specifically this means for S24 phones, but cool to see JXL!

I would like to share a very cool project I've been working on with a couple of other very talented developers: SVT-AV1 PSY

https://github.com/gianni-rosato/svt-av1-psy

SVT-AV1-PSY is the Scalable Video Technology for AV1 (SVT-AV1 Encoder and Decoder) with perceptual enhancements for psychovisually optimal AV1 encoding. The goal is to create the best encoding implementation for perceptual quality with AV1.

We've already implemented a couple of unique features not present in mainline that do appear to produce BD-rate gains on a number of clips already!! Please check it out!

Explore insightful benchmarking of the latest SVT-AV1 1.8.0 encoder and how it fares when encoding animation. The author, Trix, spared no expense in creating an incredible number of detailed graphs to support their conclusions about which settings are the best and why. Give it a read!

It looks like #GNOME is ready to embrace #jpegxl into its ecosystem! Wallpapers are being switched to JXL from WebP, & GNOME Web will adopt JXL support through WebKitGTK. The GNOME SDK is also going to be built with libjxl from now on!

In #WWDC, it looks like Apple may have secretly dropped a hint about a new feature in Safari. Hopefully this is legit and we can welcome #jpegxl to Safari & the Apple ecosystem soon!!

This is really cool, but this is also very much a solved problem with newer codecs like #jpegxl. If Google would just embrace JXL & push for widespread support, we might actually be able to move past JPEG instead of using hacks like this. #AVIF isn't going anywhere outside specific Web use cases, as much as I really like it due to its great coding efficiency for certain quality ranges.

Manually edited (from RAW) photo of a sun shower, shot through my window. A reflection of my Pixel's camera is visible on the right, and the sun is visible through the clouds in the middle. The image looks dramatic and moody.

@wb @RL_Dane Does JXL not have any directional prediction or shared data between blocks? How does it handle generation loss so well?

I assumed the VarDCT built on every coding technique that previous DCT variants used, although I’m not well versed in what those were & I may be off base

Nvidia & Intel both have hardware accelerated AV1 encoding. Would u like to know which encoder performs better, among other things? Take a look at my blog post here: https://giannirosato.com/blog/post/nvenc-v-qsv/

Thorium’s JXL patch is now BSD. This more permissive license will allow basically any Chromium-based browser to implement JPEG-XL support, as the hard work has been done for them.
