Firefox 115 Now Available With Intel GPU Video Decoding On Linux
www.phoronix.com

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.

      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.

        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?

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

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