I usually go for VP9 and opus in a webm container. This is widely supported, because it is Google sponsored, used on YouTube and supported by all browsers. As other people told you here, DVD are not 720p, they are 480 or 576 interlaced or progressive. You can find more details on Wikipedia.

AV1 is the best compressing standard for video, but it is slower in encoding than HEVC (usually). VP9 is the predecessor, which is compresses better than AVC and comes close to HEVC. Speed wise is comparable to x265.

Opus is the best audio standard, the only reason you may want to avoid it is for incompatibilities with older hardware players (in car radios, BluRay players,…).

Ubuntu Server seems the obvious choice. Just roll with the DE it will install as dependency for one of your needed apps.

What do you mean? In most OSS that i use (surely all KDE apps) there is a donate button in the menu bar that opens a webpage with a PayPal button… I don’t know how easier could it be.

My point wasn’t that C++ is good. My point was that C++ can and is used everywhere (desktop applications, web applications, OSs,…) and is older than Rust. So I feel that “this is the first general purpose language that can be used for all projects” is false. Probably “this is the first general purpose language that I (and many others) like to use for all projects” is true, but is a different claim.

TLDR: You said Rust was first language capable of system, app and web, it isn’t.

I feel like C++ is as competent as Rust for any project and it’s definitely older.
