FFmpeg-Builds VS mrustc

Right now, I use ffmpeg to encode AV1 videos using libaom-av1 that comes with the BtbN ffmpeg daily auto static builds for Linux. The command would look like:

I downloaded FFmpeg from here (ffmpeg-master-latest-win64-gpl.zip) and installed following this guide, but when I right click and clip an audio it doesn't work? It just downloads it normally

Some more information here. The GitHub user has already removed repo from the code and uses a tarball now.

Reddit Blackout has failed, but you should under no circumstances be posting 1gb videos of noise on every subreddit you can find in an effort to suffocate reddits bandwidth and processors, and you absolutely shouldnt download ffmpeg from https://github.com/BtbN/FFmpeg-Builds/releases/download/latest/ffmpeg-n6.0-latest-win64-gpl-6.0.zip and then extract it to your C:/ drive, open the command prompt and type "cd C:/ffmpeg", and then proceed to copy paste the line below:

You probably can use ffmpeg for that.

The FFmpeg project itself has never provided compiled binaries. If you ever want support from them, you'll have to use a compiled version from the latest source. That's why I also provided a link to the BtbN daily builds. (John Van Sickle's builds are not quite up to date)

You are not using latest FFmpeg, right? Here, our official binaries: https://github.com/BtbN/FFmpeg-Builds/releases/tag/latest

Used ffmpegif anyone is wondering

You have to manually use a more updated version. Such as this one: https://github.com/BtbN/FFmpeg-Builds/releases/download/latest/ffmpeg-n6.0-latest-linux64-gpl-6.0.tar.xz

No, you don't. Existential proof: mrustc ignores lifetimes. Just flat out simply ignores. It changes some corner-cases related to HRBT, yet rustc compiled by mrustc works (that's BTW mrustc exist: to bootsrap the rustc compiler).

Incidentally C++ is the only way to bootstrap rust without rust today.

https://github.com/thepowersgang/mrustc

Well, there is mrustc[0], a Rust compiler that doesn't include a borrow-checker, so it's possible to compile (at least some versions of) Rust without a borrow checker, though it might not result in the most optimized code.

AFAIK there are some optimization like the infamous `noalias` optimization (which took several tries to get turned on[1]) that uses information established during borrow checking.

I'm also not sure what the relation with NLL (non-lexical lifetimes) is, where I would assume you would need at least a primitive borrow-checker to establish some information that the backend might be interested in. Then again, mrustc compiles Rust versions that have NLL features without a borrow-checker, so it's again probably more on the optimization side than being essential.

> Maybe another memory safe language, but Rust has severe bootstrapping issues which is a hard sell for distros that care about source to binary transparency.

It is possible to bootstrap rustc from just GCC relatively easily, although it's a little bit time consuming.

You can use mrustc to bootstrap Rust 1.54: https://github.com/thepowersgang/mrustc

And from then you can go through each version all the way to the current 1.72. (Each new Rust version officially needs the previous one to compile.)

Have you tried this route : https://github.com/thepowersgang/mrustc ?

Mrustc supports Rust 1.54.0 today

There are three. The official one, mrustc (no borrow checker, but can essentially compile the official rustc) and GCC (can't really compile anything substantial yet). Only rustc is production-ready though.

That probably depends on what you mean by problematic. Having an ever increasing chain of dependencies isn’t the most desirable situation so there has been some work to trim the bootstrap chain. In 2018, when the blogpost I linked above was written, mrustc was used to bootstrap rust 1.19.0; now mrustc can bootstrap rust 1.54.0 so the chain to recent versions is much shorter than if all those intervening versions back through 1.19.0 needed to be built. https://github.com/thepowersgang/mrustc
