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

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.
[Media] I stumbled upon this when reading an ARM vs x86 comparison, and it made me giggle

… but that's a problem surprisingly limited to C or 'find symbols by name'-land. Inside a Rust executable, there is no problem applying multiversion or manual alternatives to relevant methods that are actually in the hotpath, and thus executing them with a recent instruction set while being compatible at the same time. That's infinitely harder if you can't simply compile the function multiple times because it would lead to (undetected, dynamic) linker conflicts en-masse.
Which open-source Rust projects have getting-started bugs/FRs?

Given your qualifications, optimizing the Huffman decoding in jpeg-decoder crate sounds like a good opportunity. 50% of the entire decoding time is spent there; any improvements in it would translate to significant performance gains for decoding JPEG images. The tracking issue is here: https://github.com/image-rs/jpeg-decoder/issues/155
