Firefox not able to use hardware video decoding on NVIDIA GPU

Histole · 2026-03-24 03:32:56

Hello all, I have an RTX 3090 in my system.

Running

nvidia-smi dmon -s u

in my terminal shows 0% usage for decode while running a YouTube video. Additionally, going to

about:support

and looking for

HARDWARE_VIDEO_DECODING

shows this:

default	 available		
env	 blocklisted	Blocklisted by gfxInfo	Blocklisted; failure code FEATURE_FAILURE_VIDEO_DECODING_TEST_FAILED
runtime	 unavailable	Force disabled by gfxInfo	Blocklisted; failure code FEATURE_FAILURE_VIDEO_DECODING_TEST_FAILED

Output for

Saw a thread request that command to be ran, not sure if that helps at all. I'm on the regular kernel and have

nvidia-open-dkms 590.48.01-4

installed.

Thank you.

I went ahead and changed some of the configs in about:config, now hardware video decoding shows as forced enabled by user. Though the "env" section still shows as blocked "Blocklisted by gfxInfo Blocklisted; failure code FEATURE_HARDWARE_VIDEO_DECODING_NO_LINUX_NVIDIA". Even though it shows force enabled, I don't see any decoding usage when I play a YouTube video.

What VAAPI shim did you install, what's the output of

vainfo

?

There seems a problem w/ the xwayland implementation of your compositor…
Please post your Xorg log, https://wiki.archlinux.org/title/Xorg#General and test whether FF HW video acceleration works on an actual X11 session (eg. openbox or icewm will do)

But I misread gfxinfo as glxinfo and it's also not relevant since you effectively overrode it, https://bbs.archlinux.org/viewtopic.php … 3#p2078733

I don't see any decoding usage when I play a YouTube video.

Do you see a difference in CPU use when using the override and when not?
I'm not sure in how far this would show up in nvidia-smi due to the CUDA implementaiton.
You can test

mpv --hwdec=vaapi /path/to/video.mp4

to see how VAAPI is reflected in nvidia-smi (and whether mpv allows you to use vaapi)

Using --hwdec with mpv on local video shows a increase in nvidia-smi dec%
A better tool may be nvtop (package nvtop). When using GPU for decoding it shows in utilization meter and in an extra DEC-meter when hw decoding is used.

I've tested mpv with:
mpv --hwdec=vaapi
mpv --hwdec=auto (//edit which uses vulkan then)
mpv --hwdec=nvdec
All settings increase/shows gpu hw decoding both in nvidia-smi and nvtop.

So it seams that it is a firefox setting.

I also don't get any indication with nvidia-smi and nvtop when playing my local video in firefox directly.

I don't see a difference in CPU usage, maybe a small amount but will play videos at around 10 W.
I noticed if I play a MPV video without specifying decoding, it will play fine at 60 W on the GPU (my idle wattage). My CPU is also around normal levels and not elevated. But then if I specify decoding, the dec % on nvidia-smi will go up to 3-5%. Oddly, the power consumption grows to 150 W in this case, making it completely pointless as it doesn't change how I view the video. Could it possibly be that it's disabled on Firefox for this very reason? Unnecessary power draw?

MPV --hwdec=vaapi: 150 W GPU 10 W CPU
MPV: 55 W GPU 10 W CPU

I'm consistent with what you're seeing. Though when I enable decoding for MPV, my power usage on the 3090 goes up to 150 W, versus 60 W (idle) when not having decoding enabled. Even though there's no difference when watching the video, which means that decoding could be useless in this case. My CPU barely goes up enough watts to care. GPU usage goes up in all scenarios when paused versus playing.

seth · 2026-03-24 21:25:56

Tbc, you absolutely don't want to use VAAPI when you can use VDPAU, try --hwdec=vdpau

Do you get better results w/ chromium or vivaldi / https://archlinux.org/packages/extra/x8 … eg-codecs/ ?

GerBra · 2026-03-24 21:55:00

--hwdec=vdpau

vdpau gives me no gpu acceleration on plasma/wayland (nvidia-smi and nvtop), also mpv (I)nformation don't show HW decoding on vdpau.
vdpauinfo shows correct output on my nvidia (nvidia-open-dkms 590.48.01-4)
Isn't vdpau no only useful on XOrg?

On my local video the gpu decoding % shows:
|hwdec| gpu overall utilization | dec% |
| vaapi | 4% | 3% |
| vulkan | 24% | 10%
| nvdec | 5% | 3-4% | nvdec gives me IMHO a lower quality...
So vaapi seems to be the "best" hw accel on my side...(?)

CPU usage on each setting doesn't differ widely.
Decoding with mpv only on CPU (without any HW accel) also shows only a slightly increase of cpu usage...

//Edit: next day i could test a different browser, but as stated: i don't care realy on video and brosers myself...

seth · 2026-03-24 22:04:56

There're no technical reason for vdpau not to work on wayland and nvidia suggested to focus on that ~1yr ago, might indeed still require xwayland, though.
As long as vaapi doesn't just mostly charge the CPU (you might want to look at the overall power draw)

Decoding with mpv only on CPU (without any HW accel) also shows only a slightly increase of cpu usage...

Tried vp9/h265 2k or 4k?

I tried Chromium, I couldn't get decoding working on there either. Exhibits the same behavior as Firefox.

If I select vdpau, I get 0% decoding, and GPU wattage is at 55 W (idle). Usage does go up though. I couldn't notice a quality difference, if there even is meant to be one.

I suppose I'll just let it be the way it is?

Nooo.... My eyes are old, don't need/have these (or any output that benefit from this resolutions)

Myself (old school) record german sat tv (only free) with vdr, so max a FullHD(1080?) resolution...
//Edit: my test video file is: (h264 1280x586 50 fps)

What i normally watch (broswers or video play prog), i never must really care if it's CPU or GPU accelerated <g>

This indicates IMHO that with nvidia on wayland no browser(firefox,chromium) use hw accel "out of the box". Or with some "tricks" from the wiki...

Verified both in nvidia-smi and nvtop.

Not sure because I also have the nvidia open dkms driver.

GerBra · 2026-03-25 01:41:28

Not sure ...

Me too! <g>
Never watched so many videos in web browsers like today ;-)

As mentioned, i have accel both with chromium and vivaldi ootb.
Tested with a local h264 video.

With youtube, both browsers show different things according the video you watch, which resolution.
On an LinkinPark video which is named as 4k i get hw accel first when i user higher resolutions/quality. 1440p and upper. Then chromium and vivaldi use hw accel (nvidia-smi,nvtop->DEC meter).
Lower resolutions use no accel.
So it matters WHAT you test with different browsers, what codec is supplied and what resolution.
I don't know if there is a real test video url which could be used to test (never searched). I would strongly recommend to also test BASIC GPU ACCEL in a browser with a local video you have (h.264/265).

And as mentioned, only in firefox myself get never any gpu accel... (local video or youtibe)

I could test something if you (both) need a "third meaning", but i have no further ideas or ambitions to go deeper in browsers+videos...
