hi, i switched to manjaro a while back it is an awesome experience overall but one thing is bothering me although hardware acceleration is working but on firefox and chrome video decoding is disabled which results in high cpu usage in youtube for example which is horrible for battery. is there any way i can fix that any leads would be great vaapi doesn’t support my cpu
Welcome to Manjaro!
Please read this:
and post some more information so we can see what’s really going on. Now we know the symptom of the disease, but we need some more probing to know where the origin lies…
P.S. If you enter a bit more details in your profile, we can also see which CPU/GPU you have, …
P.P.S. Also please provide the output of the FireFox about:config section, filtered on gpu-process
What CPU do you have? Please provide inxi -Fxza
We have that link in the current forum as well
I did mention CPU in the title but there you go about:config and inxi sorry for not providing enough info

Oh woops, I didn’t realize the 430m was the intel chip. That’s old!
Unfortunately, the only hardware acceleration for firefox and chrome are via VA-API. Since your CPU doesn’t support it, you’re kinda out of luck here… Looks like Intel didn’t support it until Broadwell (2014).
Yea it is old indeed, haven’t used it since years, couple days ago i slapped in an old ssd and with linux it flies, unfortunately watching videos results in 30 40% cpu usage 1440p ends up in the 60s thought there is a workaround for that, thanks for your help
Hold on, it is supported if you look at the second line it is supported by libva-intel-driver which i checked is installed on my system both 32 and 64 bits now why it is not working?
I totally missed that… that you follow these steps for Firefox?
https://wiki.archlinux.org/index.php/Firefox#Hardware_video_acceleration
Also, VA-API for X isn’t available until Firefox 80, so unless you’re running the beta or dev version (firefox-developer-edition), you can’t do it. Or swap to Wayland.
Sorry! Missed that!

about:configis correct. - I know nothing about Quanta GPUs so cannot help you any further…

Well i tried everything except switching to wayland i have no idea how to do that, is it working for you guys with iGPUs ?? and how to switch to wayland?
So it doesn’t work with firefox-developer-edition at all either?
Nop tried everything with correct variables and forced YouTube to h264 and still same thing
I tested on ubuntu chromium dev and it worked cpu usage dropped to 10%, back to manjaro i got chromium-vaapi to work but funny thing is that it uses 20% video engine on gpu and 50% cpu so by enabling it things got worse on mpv same story high cpu usage even if video decoding is working confirmed by intel_gpu_top something is not right in Arch
