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.

While some of us had it turned on for some time, some didn't. Looks like it is fully stable now.

Yey! Test it by starting intel_gpu_top and than playing video in firefox, if row "Video" goes over 0.0% it is working!

Of course, you need second monitor, it goes down to 0 if video is not visible, since Firefox is not rendering it.

VAAPI has been around for a while. Do you know why it took so long for Firefox to integrate?

[–] [email protected] 4 points 1 year ago

Bugs.

There has been a hell of a lot of work done here both in Firefox, as well as other projects like mesa to get this enabled.

[–] [email protected] 1 points 1 year ago (1 children)

It was already integrated for non Intel GPUs

[–] [email protected] 8 points 1 year ago* (last edited 1 year ago)

That's not what has happened here. This is the first time any major browser has enabled vaapi hardware acceleration by default on Linux.

It has been previously available either to users who have switched it on, or maintainers who changed the upstream default.

They are initially enabling for intel only due to some amd bugs that need to be ironed out. AMD will be next.

On my system is very busy on Render/3D, does that mean that the video acceleration is not working?

[–] [email protected] -4 points 1 year ago (1 children)

Congratulations!!! Only a couple of decades behind other operating systems!

[–] [email protected] -1 points 1 year ago (1 children)

OS or browsers?

[–] [email protected] 1 points 1 year ago (1 children)

Same browsers on other operating systems. I don’t think Chrome enables it on Linux.

[–] [email protected] 2 points 1 year ago

You're correct. This is the first time a major browser has enabled vaapi by default on linux upstream.
