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!

The Tensor G3 is the first smartphone SoC to support hardware-accelerated AV1 encoding. It supports AV1 encoding at up to 4K60. No application (including the Pixel Camera app) takes advantage of this, though, likely due to a lack of platform support.

Browser maker love-in snubs next-gen image format

"... 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.

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.

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!

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.

The OnePlus Watch 2 is here, and it’s quickly become my favorite Wear OS smartwatch after only a few days of use! Its battery life has been STELLAR - it lasted me 75 hours during the first cycle! This is thanks to its huge battery (500mAh versus 306mAh in the Pixel Watch 2) and also Google’s new Wear OS hybrid OS interface.

I’ll share my full impressions on tomorrow’s episode of the Android Faithful podcast, but here’s a rundown of the key specs and features:

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 :)
