AOM AV1 encoder/decoder in Debian needs update to enable AVIF saving
libavif supports building selected dependencies locally. I have a script which builds static libaom to be bundled into libavif together with libyuv. It was necessary to add -DCONFIG_PIC=1 https://github.com/novomesk/qt-avif-image-plugin/blob/master/ext/build_local_libaom_libavif.sh Does Debian allow bundled dependencies? Because that would be a possibility how to build feature complete libavif.

How to open AVIF image format?
KDE apps (for example gwenview) are able to open AVIF when new versions of the following packages are installed: shared-mime-info, libavif, kimageformats When you have old packages, you can still register image/avif mime-type manually and to build/install the Qt plug-in manually. If you want to try it, read manual How to install AVIF support in KDE https://github.com/novomesk/qt-avif-image-plugin

Learn x86-64 assembly by writing a GUI from scratch
Sure. You'll see it very often in codec implementations. From rav1e, a fast AV1 encoder mostly written in Rust: https://github.com/xiph/rav1e/tree/master/src/x86
Large portions of the algorithm have been translated into assembly for ARM and x86. Shaving even a couple percent off something like motion compensation search will add up to meaningful gains.
Or the current reference implementation of JPEG: https://github.com/libjpeg-turbo/libjpeg-turbo/tree/main/sim...

SISVEL VP9/AV1 patent declared invalid in China
Again, if anything AOM would be the one restricting licenses to AV1 (if they chose to) except AOM has stated and also published AV1 in a way to allow license free access to development (which allows people to make forks of the official build like it's open source) and usage. (1)(2) I don't see why they would suddenly change this.
- Any new Opensource projects in (rust) looking for contributors. I want to start my journey as an OSS contributor.

A little script to parse large libraries to AV1, if you're interested
You can speed up the sampling process with --vmaf n_subsample=5, which in my experience works more accurately than either 2 or 4, possibly due to this bug/feature present in multiple encoders. You might also need to manually set the number of threads used for VMAF calculation with --vmaf n_threads=16, but YMMV.
