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.

All I Want for Christmas Are Useful Detail-Retention Settings
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)
- Dav1d, fast AV1 decoder, version 1.0.0 released

H.264 is magic: a technical walkthrough
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
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.

AOM AV1 encoder/decoder in Debian needs update to enable AVIF saving
libavif supports building selected dependencies locally. I have a script which builds static libaom to be bundled into libavif together with libyuv. It was necessary to add -DCONFIG_PIC=1 https://github.com/novomesk/qt-avif-image-plugin/blob/master/ext/build_local_libaom_libavif.sh Does Debian allow bundled dependencies? Because that would be a possibility how to build feature complete libavif.

How to open AVIF image format?
KDE apps (for example gwenview) are able to open AVIF when new versions of the following packages are installed: shared-mime-info, libavif, kimageformats When you have old packages, you can still register image/avif mime-type manually and to build/install the Qt plug-in manually. If you want to try it, read manual How to install AVIF support in KDE https://github.com/novomesk/qt-avif-image-plugin
