leftwm VS rav1e

(Also I wouldn't mind if you want to contribute to leftwm ;))

LeftWM if you are adventurous and want to support more Rust projects on Linux.

I'm using a tiling window manager (LeftWM) and picom with experimental backends for compositing. I'm running into issues configuring picom for use on my laptop when I am on battery power. Two problems arise:

I've looked at these: - DWM: A popular, compact WM written in C - LeftWM: A popular, configurable WM written in Rust - GabelstaplerWM: An obscure, compact WM written in Rust - XCB DWM: An abandoned rewrite of DWM using XCB

Been using and liking LeftWM: https://github.com/leftwm/leftwm

In particular, I think that "ultrawide-vertical-stack" (based on "CenterMain" from LeftWM) is quite close to what you are looking for. Give it a try with komorebic change-layout ultrawide-vertical-stack!

Once again I'm happy to answer any questions, and I want to give a special thanks to nog, leftwm and umberwm, whose work this project borrows from and builds upon.

Sure. You'll see it very often in codec implementations. From rav1e, a fast AV1 encoder mostly written in Rust: https://github.com/xiph/rav1e/tree/master/src/x86

Large portions of the algorithm have been translated into assembly for ARM and x86. Shaving even a couple percent off something like motion compensation search will add up to meaningful gains.

Or the current reference implementation of JPEG: https://github.com/libjpeg-turbo/libjpeg-turbo/tree/main/sim...

Again, if anything AOM would be the one restricting licenses to AV1 (if they chose to) except AOM has stated and also published AV1 in a way to allow license free access to development (which allows people to make forks of the official build like it's open source) and usage. (1)(2) I don't see why they would suddenly change this.

You can speed up the sampling process with --vmaf n_subsample=5, which in my experience works more accurately than either 2 or 4, possibly due to this bug/feature present in multiple encoders. You might also need to manually set the number of threads used for VMAF calculation with --vmaf n_threads=16, but YMMV.

That remember me of https://github.com/xiph/rav1e which is an AV1 encoder

I put in the request for ffmpeg passthrough mastering-display data a few years ago and haven't heard of any support yet.

It's getting there.. Initial steps for FFmepg: https://patchwork.ffmpeg.org/project/ffmpeg/list/?series=8444 rav1e: https://github.com/xiph/rav1e/pull/3000

It's entirely possible to re-use bits of other HW encoders for the first pass (motion estimation, etc).
