Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

[dav1d git] x86: Add high bitdepth AVX2 asm (massive 10-bit+ AV1 decoding performance increase for AVX2 capable CPUs)
https://github.com/videolan/dav1d/commit/1cf1b309bb2c40e25582f2ace6917d84e45f354b#diff-30d8f6be6320feeacf686be94f48c70869b52630e01ea625f0f15adc0d57c3e4R26

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.
- assembly from dav1d 1.1.0 now integrated into rav1e

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.

rav1e wrong mastering-display output?
I put in the request for ffmpeg passthrough mastering-display data a few years ago and haven't heard of any support yet.

Release Notes: Safari 16.4 Beta adds AV1 codec + hardware decode for WebRTC
It's entirely possible to re-use bits of other HW encoders for the first pass (motion estimation, etc).
What are some alternatives?
