From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

"Set for a year-end release, AV2 is not only an upgrade to the widely adopted AV1 but also a foundational piece of AOMedia’s future tech stack.

AV2, a generation leap in open video coding and the answer to the world’s growing streaming demands, delivers significantly better compression performance than AV1. AV2 provides enhanced support for AR/VR applications, split-screen delivery of multiple programs, improved handling of screen content, and an ability to operate over a wider visual quality range. AV2 marks a milestone on the path to an open, innovative future of media experiences."

It's not for the end user at this point, it's for YouTube/streaming companies to spend less on bandwidth at existing resolutions. Even a 5% decrease in size for similar quality could save millions in bandwidth costs over a year for YouTube or Netflix.

Thanks for the clarification, it makes me wonder though, is it bandwidth saving at no user cost? i.e is the compression improved without requiring more compute at the end to decompress?

[–] MrMcGasion@lemmy.world 3 points 1 day ago (2 children)

Without hardware decoding, it will take more compute to decompress, but sites usually wait to fully roll out new codecs until hardware decoding is more ubiquitous, because of how many people use low-powered streaming sticks and Smart TVs.

Then it's arguably delegating some of the cost to the final user, large streaming companies spending a bit less on IXP contracts while viewers have to have newer hardware that might need a bit more energy too to run.

On the upside, the end user needs to use up less data for the same content. This is particularly interesting under 4G/5G and restrictive data plans, or when accessing places / servers with weak connection. It helps avoid having to wait for the "buffering" of the video content mid-playback.

But yes, I agree each iteration has diminishing returns, with a higher bump in requirements. I feel that's a pattern we see often.
