What is libre culture?

Libre culture is all about empowering people. While the general philosophy stems greatly from the free software movement, libre culture is much broader and encompasses other aspects of culture such as music, movies, food, technology, etc.

Some beliefs include but aren't limited to:

That copyright should expire after a certain period of time.
That knowledge should be available to people, not locked away.
That no entity should have unjust control or possession of others.
That mass surveillance is about mass control, not justice.
That we can all band together to help liberate each other.

Rules

I've looked into the ways other forums handle rules, and I've distilled their policies down into two simple ideas.

Please show common courtesy: Let's make this community one that people want to be a part of.
Please keep posts generally on topic
No NSFW content
When sharing a Libre project, please include the name of its license in the title. For example: “Project name and summary (GPL-3.0)”

Libre culture is a very very broad topic, and while it's perfectly okay for a conversation to stray, I do ask that we keep things generally on topic.

What are the best open file formats? (lemmy.ml)

As far as I know, open file formats have become the standard for basically all industries and types of files. However, some of them, like the Microsoft Office Formats, are still proprietary. I have seen Open Office documents and Ogg being recommended for Office documents and audio files, respectively, but I'm somewhat confused about other types of formats like video.

Video is a can of worms. Video files have the concept of a container (like .mp4, .mkv) and codecs (h.264, h.265). Making it worse, you also have embedded audio which has its own codec (mp3, ac3, aac, ogg, flac).

For me, mp4 container with h.264 video and aac audio have the widest hardware support- videos encoded that way pretty much play on everything and well.

It’s going to be a couple more years before good hardware support for h.265 is ubiquitous. I see .mkv with h.265 used a lot for 4K stuff, and while well supported on desktop, device support is still spotty.

HEVC is so good at compression though!

It sucks about all the patent bullshit though, same thing blocking HDMI 2.1 adoption too.

I agree. One day we’ll hit a point where no matter how much money you toss at it, it wont get much better and at that point, open source will catch up, and then companies will opt for that because it’s free, until then that license gets you x% better quality/byte ratios, it gives your company and “edge” to go all in on it.

AV1 is already almost like that though.

You’re right, but that universal hardware support is still lacking. It’s spotty on different tv boxes, phones, consoles. It’ll get there!

Video is tougher as it changes every few years. Once a new standard is out there is also a little lag before there is hardware decoding. Additionally the video codec and extension are different things. I’m going to talk about codecs as I think it’s more important than file type.

Hardware decoding is important especially for mobile devices and software decoding will run the processor and eat up your battery.

For video, right now, the technically best format I think is AV1. If I’m not mistaken it’s open source or at least doesn’t have royalties.

Images are kind of the same story, but browser support is the issue.

I think jpegxl is supported to be pretty great, but Google is trying to push their own standard which I believe is technically inferior in some ways. Because of that Google had support for jpegxl in chrome and then they removed it from chrome.
