FFmpeg-Builds VS nomicon

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

it’s even written by the same person that wrote the Nomicon (the guide to the dark arts of unsafe)

If you want to dive deeper you can always have other options but now there are concrete cases, if you want to do low level thing https://doc.rust-lang.org/nomicon/ while if you want multi thread/concurrency stuff https://marabos.nl/atomics/ . There are many many books so you will have to point yourself to what you want

Nonononono. SeqCst is the most error prone memory order: https://github.com/rust-lang/nomicon/issues/166

Hope this helps. For more details, see the Rustonomicon. I referenced the subtyping chapter here extensively.

Nice video! Glad I could help out. This stuff is hard, and I'm still learning a lot about it myself even years later. The Rustonomicon is a great read if you haven't already.

Have you got a moment to read through the good book , after reading through this perhaps try the Rustonomicon.

That is not what UB means. Undefined Behaviour is behaviour that the compiler is allowed to assume will never happen, and which can consequently cause miscompilations due to optimisation passes gone wrong if it does in fact occur in the source code.

It's true that Rust does not have a written specification that clearly delineates what is and isn't UB in a single place. But:

1. UB is impossible in safe code (modulo bugs in unsafe code)

2. There are resources such as the Rustinomicon (https://doc.rust-lang.org/nomicon/) that provide a detailed guide on what is and isn't allowed in unsafe code.

In practice, it's much easier to avoid UB in Rust than it is in C++.

However, this is a wide topic out of scope for a Reddit comment, so maybe just read the Rustonomicon. It explains everything about data handling in Rust.

The ownership model & borrow checker makes rust a bit of an awkward language in which to write complex data structures like trees and graphs. It can be done - since you can always use raw pointers & unsafe code when you absolutely need to to treat rust like C. But the language fights you, and the community can get a bit moralistic about this sort of thing. The rust nomicon is a fantastic resource for learning the limits of the borrow checker, and where and how to use unsafe code correctly. You will need unsafe less than you think you will, but sometimes you will have no choice.
