Snapshot doesn't work until camera is unplugged and plugged back in or pipewire or wireplumber is restarted

[Jeremy Bícha]

Impact
------

Snapshot fails to show the camera feed when a USB camera is present in addition to the embedded one since boot.

Test plan
---------

*Power a computer with an integrated webcam off.
*Plug an USB camera in.
*Power the computer.
*Start Snapshot.

Expected: Snapshot starts showing the live feed of one of the cameras.

Regression potential
--------------------

Detection and use of devices relying on the V4L2 on systems using Pipewire.

Original description
--------------------

Ubuntu 24.04 LTS Beta

On multiple computers, it appears like Snapshot doesn't work until I either:
- unplug the external USB webcam and plug it back in
- use the Fn key to disable the internal webcam and re-enable it

I have reported this issue upstream

[Tim Richardson (tim-richardson)]

For me the fix included the new version of pipewire (now released in 24.04) AND adding my user to the video group

[Ubuntu QA Website (ubuntuqa)]

This bug has been reported on the Ubuntu ISO testing tracker.

A list of all reports related to this bug can be found here:

[corrado venturini (corradoventu)]

I still have same problem on Ubuntu 24.04 with gnome-snapshot: Installed: 46.2-1ubuntu2
and also on Ubuntu 24.10 with gnome-snapshot: Installed: 46.2-1ubuntu3
on Ubuntu 24.10 I have pipewire: Installed: 1.2.2-1

[Tim Richardson (tim-richardson)]

For me, the problem in 24.04 is reproducible, but not after I add my user
to the video group.

I have this problem since I installed Ubuntu 24.04 LTS and it persistis on Ubuntu 24.04.1 LTS. I didn't happen on Ubuntu 23.10.

[corrado venturini (corradoventu)]

after 'systemctl --user restart wireplumber.service' snapshot shows 'camera not responding'

[Raul Grangeiro (raulgrangeiro)]

@corraduventu tray this command: systemctl --user restart pipewire

[corrado venturini (corradoventu)]

after 'systemctl --user restart pipewire' snapshot starts but I see a heavily pixeled image

[Hans de Goede (j-w-r-degoede)]

I have submitted a pipewire merge-request upstream which should fix this:

https://gitlab.freedesktop.org/pipewire/pipewire/-/merge_requests/2118

[Sebastien Bacher (seb128)]

I've pushed an Oracular test package with the fix to https://launchpad.net/~ubuntu-desktop/+archive/ubuntu/ppa now, feedback is welcome if anyone having the issue would like to give it a try. (I will also add a Noble version in a bit once I've adapted the patch to apply to the version we have in that serie)

[Raul Grangeiro (raulgrangeiro)]

@seb128 is there a way to update just the pipewire to test the new packege you submitted and avoid updating the other packages contained on the PPA?

[Sebastien Bacher (seb128)]

It's the only package published for Oracular in that ppa

[Raul Grangeiro (raulgrangeiro)]

But I'm on noble right now.

After installing your PPA snapshot works fine on my Oracular

Any noble volunteer to test the rebased patch for 24.04? PPA: https://launchpad.net/~nteodosio/+archive/ubuntu/wirepipe.

[Alexander Browne (elcste)]

I can try it when I am at home tonight (about 10 hours from now).

I haven't been following the details of this bug. Am I right that after installing this package, the idea is that if I open Snapshot the camera should just work?

[Raul Grangeiro (raulgrangeiro)]

I'll do it, @nteodosio. I'll add the PPA and update right now.

Great, thank you confirming!

[Raul Grangeiro (raulgrangeiro)]

Nathan, when a bug is corrected, as you helped us (thanks for that). What happens to the fix for it to reach us?

[Nathan Teodosio (nteodosio)]

Raul, for users in a stable release (as is the case for 24.04, Noble), the
process is described at https://wiki.ubuntu.com/StableReleaseUpdates.

The process is already kicked off so if everything goes to plan you can expect
in about one week to have the fix in the proposed pocket, and then maybe two or
three until it reaches the normal updates pocket which the vast majority of
users track.

[Sebastien Bacher (seb128)]

Thanks Nathan, I've tweaked the change to add the patch to the debian/patches/series and uploaded

[Robert Mader (robert.posteo)]

Hi, I just wanted to add that the upstream fixes now also have been backported to the 1.0 branch in https://gitlab.freedesktop.org/pipewire/pipewire/-/merge_requests/2145 and should be released in 1.0.9 - that should allow to drop the downstream patches again, which I guess would be nice in the long term.

[Timo Aaltonen (tjaalton)]

Hello Jeremy, or anyone else affected,

Accepted pipewire into noble-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/pipewire/1.0.5-1ubuntu2 in a few hours, and then in the -proposed repository.

Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested, what testing has been performed on the package and change the tag from verification-needed-noble to verification-done-noble. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed-noble. In either case, without details of your testing we will not be able to proceed.

Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance for helping!

N.B. The updated package will be released to -updates after the bug(s) fixed by this package have been verified and the package has been in -proposed for a minimum of 7 days.

Hi Corrado, that's pretty annoying, sorry about it.

I think ppa-purge will automatically roll back the binary packages associated with this source package for you, such that you don't need to do this manually for each of them, nor install 24.04 from scratch.

[corrado venturini (corradoventu)]

On my new installed Noble I activated proposed and try: sudo apt install pipewire/noble-proposed
but I have a huge list of changes, so I refused.
Suggestions? Thanks.

attaching text returned from apt

[Nathan Teodosio (nteodosio)]

I reckon you'd then need to install at least a number of the other binaries produced by this source package.

Jeremy pointed me to https://jeremy.bicha.net/2022/03/29/how-to-install-a-bunch-of-debs/.

You could alteratively leave the verification to me, I can only test it on Monday though.

[corrado venturini (corradoventu)]

No problem, in my new Noble installation I refused the change, so I have a working system.

Thank you all, guys, for fixing that. It's being a pleasure using Ubuntu with fast fixes of these kind of bugs. I'll be waiting for the fix to come through updates! God bless you all!

Hmmm I need to wonder how can this be if you tested the PPA successfully.

Is it possible that some binary is still behind? Can you please do 'apt update' and paste the output of 'apt list --upgradable' and 'dpkg -l|grep pipewire'?

[Raul Grangeiro (raulgrangeiro)]

Nathan, I just received the update of pipewire, after installing it I rebooted the notebook and the problem persists, the Snapshot doesn't recognize the Webcam.

Same for me: I received version 1.0.5-1ubuntu2 if pipewire, but Snapshot still displays "No Camera Found"

[Nathan Teodosio (nteodosio)]

Can you please file a new bug since this one got closed?

[Raul Grangeiro (raulgrangeiro)]

Nathan, what if we do that and not much people sign it too and it doesn't become relevant? Wouldn't be better to change the status to not fixed and fix it in this thread?

[Nathan Teodosio (nteodosio)]

That's a fair point, but is the bug as written unambiguously accurate? I.e. the original description said

> Snapshot doesn't work until I either:
> - unplug the external USB webcam and plug it back in
> - use the Fn key to disable the internal webcam and re-enable it

If I run the test plan in 24.04, namely

--->
*Power a computer with an integrated webcam off.
*Plug an USB camera in.
*Power the computer.
*Start Snapshot.

Expected: Snapshot starts showing the live feed of one of the cameras.
<---

it passes here. Can you confirm that exactly that is false (and which step fails) for you? Or if that doesn't fail as written, then it's really better to open a new bug with the steps that lead to the issue otherwise this one will become confusing as it will merge reports from two different Pipewire versions.

(On a side note I still don't understand how #30 confirmed the fix from the PPA but #49 does not, as the PPA fix is equal to the fix that thereafter landed in the archive.)

[corrado venturini (corradoventu)]

Created new bug according your suggestion: https://bugs.launchpad.net/ubuntu/+source/gnome-snapshot/+bug/2087858
Note: your PPA was working but on this system i had a lot of other applications installed.
Following test (unsuccessful) was done in system with few additional applications installed.
the NEW system created for bug 2087858 is a fresh install with just the preinstalled apps.

[Raul Grangeiro (raulgrangeiro)]

Nathan, my notebook doesn't have the Fn key to disable and enable the webcam, but it only works when I type this command on terminal: systemctl --user restart pipewire

And this is the exactly problem described on this thread. I know we're bothering you a bit, but would you try to fix it one more time?

[Nathan Teodosio (nteodosio)]

Hi Raul, this is no bother, rather helpful when a problem's context is reported. I have an idea to reproduce it and will try today or tomorrow and let you know.

[Raul Grangeiro (raulgrangeiro)]

Good morning, Nathan. Have you had success on the idea to solve the issue with pipewire?

[Nathan Teodosio (nteodosio)]

I just built an unaltered Pipewire 1.0.9 (the last one in the 1.0 branch),
'pipewire --version' says 1.0.9. Even ditching our downstream patches, Snapshot
still has what seems to be the same trouble.

I'd suggest filing a report upstream[1] (maybe it is already covered by [2] or
[3]). If you do so, they will probably want you on version 1.0.9, which is their
latest. You could build it and install it yourself or install from the PPA[4].

[corrado venturini (corradoventu)]

Your PPA contains many packages, should I install all amd packages? or just some? thanks.

[Nathan Teodosio (nteodosio)]

Just add the PPA and do 'apt upgrade' so that only the Pipewire packages that
you already have are upgraded.

Installed your PPA but problem remains.
Just updated existing issue: https://gitlab.freedesktop.org/pipewire/pipewire/-/issues/3960

SORRY, after installing Your PPA and REBOOT snapshot works fine
THANKS

[Yao Wei (medicalwei)]

@nteodosio, I have the same issue with pipewire 1.0.5-1ubuntu2, and the issue is the same and still reproducible.

(GNOME Snapshot did not find any camera / pipewire did not list any camera, unless usb unbind then bind or restart pipewire/wireplumber)

However I can confirm that backporting

https://gitlab.freedesktop.org/pipewire/pipewire/-/merge_requests/2145

instead of just

https://gitlab.freedesktop.org/pipewire/pipewire/-/merge_requests/2118

can fix the issue for noble.

The one that's currently uploaded in -updates contains only the latter

[Nathan Teodosio (nteodosio)]

Yao, I split this bug to LP:2087858 because this one was already marked fix released. In hindsight that caused more confusion than it avoided.

Anyway, in that bug I commented that I cherry picked 2145 to the PPA but the problem persisted for me[1]. #66 confirmed that and so until your comment I had no information this could work for anyone. #66 was later amended but Launchpad does not send a notification for amended comments so I never read it.

All in all with two confirmations (yours and Corrado's) I must assume I'm hitting a different problem and we should SRU 2145.

[Sebastien Bacher (seb128)]

I'm reopening this bug since the fix was not enough and uploaded 1.0.5-1ubuntu3 which replaces our incomplete cherry pick by the version of the patch that was officially backported upstream (which Nathan got tested in his ppa and confirmed to be working for people who still had the issue)

[Timo Aaltonen (tjaalton)]

Hello Jeremy, or anyone else affected,

Accepted pipewire into noble-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/pipewire/1.0.5-1ubuntu3 in a few hours, and then in the -proposed repository.

Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested, what testing has been performed on the package and change the tag from verification-needed-noble to verification-done-noble. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed-noble. In either case, without details of your testing we will not be able to proceed.

Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance for helping!

N.B. The updated package will be released to -updates after the bug(s) fixed by this package have been verified and the package has been in -proposed for a minimum of 7 days.

[Ubuntu SRU Bot (ubuntu-sru-bot)]
