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.
Firefox now supports AV1 VA-API playback

No. There are hardware encoders. For software encoding while AV1's reference encoder is very slow; both rav1e and SVT-AV1 are usable on a higher end PC built in the last few years.
I'm giving out microgrants to open source projects for the third year in a row! Brag about your projects here so I can see them, big or small!

I'm going to promote rav1e, an AV1 encoder written in Rust+ASM. Unlike the reference encoder, rav1e seeks to focus on psychovisual quality rather than pure metrics, and so to many people it is a promising alternative. However, it has some catching up to do in the speed department.
What are the differences between full-build and full-build-shared?

Just as a side note, there may be exceptions at times. For example, at one point the rav1e encoder couldn't be built statically into FFmpeg due to a (compiler?) bug. Though I have no idea if this actually affected any providers of FFmpeg builds at the time, rare problems like this can happen.

dav1d is preparing for its 1.0 release

You are looking for rav1e.

AOM AV1 encoder/decoder in Debian needs update to enable AVIF saving
3 projects | reddit.com/r/debian | 19 Oct 2021
This issue could additionally be solved by packaging rav1e, which libavif can use for encoding. Getting it included in Debian is a goal of the project: https://github.com/xiph/rav1e/issues/886
[rav1e git] Scene detection improvement(better and more advanced scene detection all around at all speeds)
for resolution higher than 360p even 720x720 it get slower like on full hd it reached 0.88 fps on i3 330m and it's slow. speed 10 is the one i recommend, at constant quality 100, with notenoughav1encodes, use 2 workers (at least) and this build https://github.com/xiph/rav1e/releases/tag/p20210831
For the same reason rav1e devs have compared aomenc's fastest preset against rav1e's slowest. To point out that rav1e massively underperforms.
Just wanna share a little test of fast encoding
1 project | reddit.com/r/AV1 | 1 Mar 2021
For rav1e, I'd recommend settings --tiles 4 and --threads 8. That should help it thread go a lot faster. You could also try the --low-latency toggle, but that makes it less efficient. Otherwise, you could try your hand at rav1e-by-gop: https://github.com/rust-av/rav1e-by-gop. It works pretty well.
Video encoder rollback optimization in rav1e

This should overall provide a nice speedup, but if you want even better threading, you could look at rav1e-by-gop, a tool specifically made to thread rav1e over multiple chunks: https://github.com/rust-av/rav1e-by-gop
