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.

AV1 is very fast and versatile but…
Calculate vmaf before you encode the whole file. -> https://github.com/alexheretic/ab-av1 has a search mode with samples, the estimation of time and filesize is very good and does everything in one step
-
AV1 tool to auto compress old video files for archive
ab-av1 auto-encode with a VMAF quality target of 97-98 + a script for the deletion of files sounds like what you need.

Automatic choose encode settings?

RFC: redb (embedded key-value store) nearing version 1.0
My case is ab-av1, a cli for encoding videos. The local db stores cached vmaf analysis.
- I'm just running videos through libsvtav1 on ffmpeg with -crf 35. Any tips to improve this command?
-
A little script to parse large libraries to AV1, if you're interested
If the goal is space saving and a consistent visual quality rather than just having a library as AV1 for its own sake, I'd use ab-av1. Not sure how (or if) it'll handle the Opus audio channels cases, but bugs can be filed.

Feels like re-encoding video gets harder and harder to improve (and use!) when new ones come along.
Try this https://github.com/alexheretic/ab-av1

Looking for some good AV1 testing and comparison results.
Use this tool and you will get excellent results https://github.com/alexheretic/ab-av1 calculates and converts automatically calculates the vmaf and crf properly
- automatically optimize (re)encoding quality
-
CRF 15 x265 advanced options
Check this, might help you optimize the process.

Are You Sure You Want to Use MMAP in Your DBMS?
I wrote redb (https://github.com/cberner/redb) using mmap, initially. However, I later removed it and switched to read()/write() with my own user space cache. I'm sure it's not as good as the OS page cache, but the difference was only 1.2-1.5x performance on the benchmarks I cared about, and the cache is less than 500 lines of code.

struct_db 0.4.0
exposure of the redb builder functionalities.

redb (safe, ACID, embedded, key-value store) 1.0 release!
redb has reached its 1.0 release. The file format is now gauranteed to be backward compatible, and the API is stable. I've run pretty extensive fuzz testing, but please report any bugs you encounter.
-
RFC: redb (embedded key-value store) nearing version 1.0
I'm just now updating the benchmarks in the readme with multi-threaded workloads :) https://github.com/cberner/redb/pull/576
-
Best local database that works on all platforms including web?
redb, but that doesn't have a stable file format yet,
-
What do you recommend for conflict-free replicated data type (CRDT) support in Rust?
I also have to support web, so I'm considering a hybrid approach with a direct IndexedDB API there and something like sqlite, percy, sanakirja, or redb on native.
-
Some key-value storage engines in Rust
Nice list, but don’t forget persy, redb and sanakirja too!
-
Are there a demand for management system of embedded storage like RocksDB? I plan to build one in Rust as the language becoming a core of many popular databases but wonder if there’s a demand. Can’t find any similar project even in other languages.
check out https://github.com/cberner/redb! it is inspired by LMDB and has comparable performance, but is entirely built in rust!
-
Meilisearch just announced its $15M Serie A, the search Rust engine strikes again
Yup, the language is immature in some domains like data replication, compilation time, lifetime expressivity, not having a default async runtime and the incompatibility of all of them. But many of these domains are worked on and improved every day this is why I love this language so much. This is because there is space for improvement. I also hope that one day we will have a pure-Rust LMDB alternative that I can contribute to without fear of C.

RFC+AMA: redb, embedded key-value store file format
they are, ya! I'm quite excited about that, and already have a PR open to use GATs. It's not enough to fix this issue though, because std needs to add support for LendingIterator too
