In, just released, Firefox 115.0 hardware video decoding is enabled by default for Intel GPUs on Linux
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?
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.
It was already integrated for non Intel GPUs
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.
