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.

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.

rav1d: a Rust port of dav1d (currently experimental)
That remember me of https://github.com/xiph/rav1e which is an AV1 encoder

Use HW hevc encoding for first pass · Issue #2945 · xiph/rav1e
I doubt much will be done on such an exotic feature any time soon. Progress has been slow on rav1e, it's missing a lot of features, and only supports tile threading.

Announcing Rust 1.67.0
rav1e is quite well maintained, the fix for the lint was merged days after the ilog PR merged. But the 0.5.1 release of rav1e was one year ago, in December 2021, while the ilog rename was end of August 2022. There hadn't been a release though of rav1e until end of November 2022, which was also a semver incompatible one. Users had only 2-ish months of time to get to the new rav1e version without experiencing breakage.

Symphonia: Audio decoding in safe Rust, now often faster than FFmpeg!
The rav1e encoder for AV1 has more assembly in it than Rust, which also doesn't bode well for memory-safe video codec implementations. But this might change once Rust provides portable and memory-safe explicit SIMD.

I built a Zoom clone 100% IN RUST
Obviously not super important, but would be super cool to see AV1 encode/decode support added. There's a great rust library for this too : https://github.com/xiph/rav1e
