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.
[rav1e git] Avoid temporary allocation of block importance costs (Small speed increase for rav1e, about 20-40% faster across speed 3 to speed 10)

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
Symphonia v0.5: ALAC, MKV, & gapless playback support

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.
Converting big video library with av1
1 project | reddit.com/r/AV1 | 4 Jul 2022
I wrote a little script that uses ffmpeg with settings similar to those in the guide, and then another ffmpeg run to extract the subtitles as vtt. I would be happy to share more of my settings if you are interested. Of course, your needs and mine may differ.

SVT-AV1 HDR Encoding (libsvtav1 with ffmpeg)

How about use the parameter "HighDynamicRangeInput" with command line "--enable-hdr 1"? It's from the official page: https://github.com/AOMediaCodec/SVT-AV1/blob/master/Docs/Parameters.md2 projects | reddit.com/r/AV1 | 19 May 2022
I used the settings from the official page: https://github.com/AOMediaCodec/SVT-AV1/blob/master/Docs/svt-av1_encoder_user_guide.md
Scalable Video Technology for AV1 (SVT-AV1 Encoder and Decoder)

AV1 Video Codec
I think a more relevant front page link/summary would be that the open-source AV-1 codec has reached the v1.0.0 milestone (18 days ago).
You can see nVidia's hardware support here: https://developer.nvidia.com/video-encode-and-decode-gpu-sup...
The take-away is that nVidia only has hardware support for AV1 on the RTX 3000 Ampere series cards.
Intel supported AV-1 decoding in its Xe-LP GPUs in 2020.
Intel also reached v1.0.0 of its open-source codec 2 weeks age, here: https://github.com/AOMediaCodec/SVT-AV1
I am not aware of any other CPU or GPU that has an AV-1 codec built in.
Seems like the SVT-AV1 documentation issue #1753 about missing presets explanation is fixed now. And it seems like the preset 0, 1 and 2 are the same thing. Plus tons of other useful encoding guidelines (like how to tune for animation etc.).
