I've put together an updated version of the Sponza scene with uncompressed PNG and compressed AVIF textures. I wrote about the process and compared the results against KTX.

Alright Mastodon, I'm looking for work.

Senior software developer, specializing in low-level, embedded, and systems programming. Previous work includes video compression (developer on AV1 and AV2), silicon verification, and scientific/numerical software. Full CV/resume available on request.

Primarily looking for remote work, but would consider in-person in the UK if the circumstances are right.

Available for either contract work through the company I run (easiest route if you're outside the UK), or direct employment.

Tagging #FediHire for visibility.

SVT-AV1 4.0.0 is here!
Changelog: https://gitlab.com/AOMediaCodec/SVT-AV1/-/releases/v4.0.0
SVT-AV1-PSY's porting efforts are fully complete, and this release also features huge AVIF improvements. Maybe the most exciting release to date by my standards – SVT-AV1 is finally a real perceptual encoder!

I got Chimera installed on the loongarch mini-PC. Installation was very smooth, basically identical to an x86_64 install. I also installed GNOME, but gnome-shell is unstable. I can log in and poke around for a brief amount of time, but then it crashes and I'm back at the login screen. Looks like I have my first project there.
