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.

There should be some major rav1e improvements in the not-so-distant future that should benefit high fidelity encoding very nicely (https://github.com/xiph/rav1e/pull/2921). And I hope someday someone gets 10/12 bit tune butteraugli working in aomenc, should provide a massive efficiency boost in pretty much all scenarios.

H.264 is magic: a technical walkthrough
9 projects | news.ycombinator.com | 17 Mar 2022
There's 3 that I know of,
libaom https://aomedia.googlesource.com/aom, the reference implementation.
https://gitlab.com/AOMediaCodec/SVT-AV1 - from the Alliance for Open Media, which Intel is deeply involved with and is spending a lot of time optimising.
https://github.com/xiph/rav1e - written in rust, also subject to a lot of optimising. It's not complete coverage of all features, intended to be used for places where libaom is too slow.
AV1 codec report
2 projects | reddit.com/r/AV1 | 28 Feb 2022
AV1 currently gets used by Netflix, YouTube (right click on any big popular video "stats for nerds) and so on. It's open source and currently has 3 different encoders. AOM as it's reference encoder available here: https://aomedia.googlesource.com/ as well as SVT-AV1 as the production encoder (like x265 for H265) available here: https://gitlab.com/AOMediaCodec/SVT-AV1 and Rav1e as community project which I personally don't have a use for at all: https://github.com/xiph/rav1e

Not AFAIK. The only relevant effort I'm aware of is rav1e, and it has more assembly in it than Rust.
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.
No library usage documentation for SVT-AV1?
3 projects | reddit.com/r/AV1 | 3 Jul 2022
Does rav1e have good documentation? From what I've seen, the best AV1 documentation by a good measure is that of SVT-AV1. Scroll down and you will see it. I would agree that they need a document on how to use it as a library. Maybe you can submit a feature request on gitlab.

SVT-AV1 artifacts during scene changes
If it shows up in 1.1 but not 0.87, I'd try a few intermediate versions (1.0, 0.9) and see where the artifacts are introduced. Then file a bug report. Give them a very short clip where it reliably shows up and the version in which you first notice it and I bet they will find and fix it right away. That will help all of us.
Newbie tip request: which to use, RAV1E, SVT-AV1, or AOM-AV1?
2 projects | reddit.com/r/AV1 | 25 May 2022
All three of the AV1 encoders work. I use SVTAV1, and I use it with ffmpeg. You just have to download a recent static master build until ffmpeg starts releasing official versions with post 1.0 SVTAV1. SVTAV1 can be very fast or it can be pretty thorough/efficient, and it makes good use of many-core computers. Some people feel that it ends up smoothing out very fine details more than other encoders, I think as part of its noise-removal algorithm. Its results seem fine to me. It is well documented (scroll down to the README) and includes ffmpeg examples and some of the tips/tricks you request. SVT-AV1 is the "official" production encoder for the AOM software implementation group.
