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.

libfdk_aac vs aac ?
It's straightforward to compile ffmpeg with libfdk_aac support to be sure quality remains high, especially e.g. build scripts.

FFMPEG + LibAOM + SVT-AV1 + Rav1e build script for Linux and MacOS
After quite a bit of searching around I was unable to find a simple way of getting a build of FFMPEG with all the different AV1 encoders, and building manually would mean I'd have to go get all the libraries that are enabled by default in say, Ubuntu's FFMPEG repo. So I took it into my own hands and modified this build script and added rav1e to the build in my fork here.

Build script for ffmpeg + rav1e on Ubuntu?
I'm currently using this build script so that I can use svt-av1, but I wan't to give rav1e a shot and it's not included. Does anyone know of somewhere I can get ffmpeg compiled with rav1e, or a relatively simple way to do it myself with all the other codecs that build script supports?

What do I need in Debian 10 to rip audio CDs to flac and convert to other formats and rip DVDs to mkv and convert to other formats?
These days the situation is much better, but you really want FDK-AAC for best quality (it's proper Fraunhofer code released as Open Source for the Android project, and now widely compatible on all platforms). You can find a standalone front end in the repos, but I prefer to build ffmpeg with support for it for more flexibility. (The ffmpeg built in default aac encoder is still noticeably worse, despite it's improvement a few years ago.)
