Vivaldi 7.0 cannot list/use USB webcam any more

majorana

Vivaldi is not able to list all of my webcams any more.
It used to until a few versions ago.
I have one built into my laptop lid (which it is usually closed) and one is a USB webcam.
If I use Falkon (chromium-based) or Firefox or Zen Browser (firefox-based) I can list (and use) both.
Is it me or this is a (new) bug?

I am running version "7.0.3495.10 (Stable channel) stable (64-bit)" under ArchLinux:

Is the webcam detected at https://webcamtests.com ?

Is it listed with
lsusb
v4l2-ctl --list-devices

Can you select it at internal page chrome://settings/content/camera

@majorana
Hi, testing https://webcamtests.com/ and I have to disable uBlock Origin Lite and allow the page to connect.
The default in Settings > Privacy > WEBSITE PERMISIONS is Ask.

Cheers, mib

@DoctorG Only v4l2-ctl works.

$ v4l2-ctl --list-devices
WEB CAM: WEB CAM (usb-0000:00:14.0-3.2):
        /dev/video4
        /dev/video5
        /dev/media2

Chicony USB2.0 Camera: Chicony  (usb-0000:00:14.0-7):
        /dev/video0
        /dev/video1
        /dev/video2
        /dev/video3
        /dev/media0
        /dev/media1

1st one is USB, 2nd is the builtin one.
Internal page chrome://settings/content/camera doesn't detect the USB one, as expected.

@majorana Can you select it at internal page chrome://settings/content/camera

majorana

Nope. Only internal.
I suspect something could have been changed in the way Vivaldi (and maybe newer chromium) uses the webcams.
V4L2 seems ok. So next in the stack could be pipewire. But unfortunately I don't know enough about it.
Any other hint, pleeease?

It seems IT IS pipewire.
By disabling it here I could use my USB camera again.
Of course, also in the settings now I can see both cameras.
I would say this is a BUG. WDYT?

DoctorG

@majorana What happens with deb package install of Chromium 130? If that works it is a Vivaldi-only bug.

I currently can not test, lack of cam.

majorana

I installed Chromium "Version 130.0.6723.116 (Official Build) Arch Linux (64-bit)".
Of course not from the deb file but rather from the ArchLinux repos.

If I go to chrome://settings/content/camera I can see both cameras.
I can only see the builtin one as soon as I enable pipewire support, as reported earlier for Vivaldi.

Then I tried to rollback the entire pipewire bundle: pipewire, libpipewire, pipewire-libcamera and pipewire-session-manager from v1.2.6 (latest) back to v1.2.5 (latest-1).
Everything now works. in all browsers also after enabling pipewire support.

So, it's either a regression in latest pipewire upgrade or something has changed within pipewire but it is not reflected into the software using it (vivaldi, chromium, firefox).

WDYT?

Then its is a issue with this updated Linux package.
I do not know if you should report to Arch Maintainer.
@BlackIkeEagle What do you think?

Please report issue to Vivaldi bug tracker, include as much detail as possible.
Once that is done, share the bug number (beginning with VB-) you got by bug report mail.

Thanks for helping us making Vivaldi better.

I think it is a bug somewhere, I have just tested it locally and I have all my cameras showing up just fine in the latest stable of Vivaldi:

7.0.3495.10 (Stable channel) stable (64-bit)

pipewire related info: I don't have the pipewire-libcamera package installed on this system, so maybe that could be related

adding pipewire-libcamera does not break it for me at this moment

Was the update of the pipewire packages done on the fly without a reboot or restart of the related services?

majorana

I have been using pipewire, the full bundle, since some time now with no such type of issues.
So I think it is a regression in pipewire, also because I get everything back to work by rolling it back.
MAybe the problem could be in some API change that has not been reflected into browsers' code yet.
I filed a bug report to pipewire team, though.

I confirm the problem on Fedora 41 with Vivaldi 7.1.3518.4 (Official Build) snapshot (64-bit).

// Works in Chrome Version 130.0.6723.116 (Official Build) (64-bit) with the pipewire camera support enabled.

edwardp

Works for me at webcamtests.com with Snapshot 7.1.3518.4 on openSUSE Tumbleweed, desktop KDE Plasma 6.2.3.

External USB camera: Creative Live! Cam Sync 1080p V2.

Pipewire version: 1.2.6, pipewire-camera not available from openSUSE.

Works for me with the same Vivaldi, pipewire and Fedora versions, but on a different laptop. Hm.

smartptr

I just found that Vivaldi had not been allowed to access the camera in the Gnome Settings → Privacy & Security → Cameras.

Once enabled, the camera works with Pipewire.
