Seeing this as well on nixos-unstable.

Snapshot fails to load camera but Cheese works.

This is the Snapshot output I'm getting:

Since this works fine for me™ (i.e. both starting from terminal and from Activities works fine), I am not sure where to start help debug this. I noticed that upstream now has a TROUBLESHOOTING.md though I am not sure if that can actually help, maybe if neither the flathub build (also works for me) nor a pipewire bump helps then asking for help on upstream is okay :upside_down_face:

Posting my outputs on various things (I am on https://github.com/NixOS/nixpkgs/commit/5a09cb4b393d58f9ed0d9ca1555016a8543c2ac8, using built-in camera on Dell Inspiron 7591):

Camera with no detected cameras

Weirdly, there are no significant environment differences I can see:

Since 14fb201c7ca9866ea9fd5bf953cb077191ce48ce swapped cheese for snapshot, there's no working camera app in NixOS 23.11 / GNOME (by default) :cry:

nixos-discourse commented 7 months ago

This issue has been mentioned on NixOS Discourse. There might be relevant details there:

https://discourse.nixos.org/t/nixos-23-11-released/36210/34

hpfr commented 7 months ago

It also works fine for me regardless of launching from Activities/Bash. Let me know if any logs would be useful.

bjornfor commented 7 months ago

Now it works for me: snapshot shows camera output :tada:

I'm on NixOS 23.11 (commit d02d818) and iIt works both from GNOME Shell and gnome-terminal.

accelbread commented 7 months ago

Still not working here on unstable (5f64a12a728902226210bf01d25ec6cbb9d9265b). Is there commits on 23.11 not on unstable?

danilo-alm commented 6 months ago

Probably not a Nix problem, the same is happening with me on Arch. Starting from terminal triggered a pop up asking for camera access, but nothing changed. After the pop up, "Camera" (snapshot) was listed untoggled (no access) under settings -> privacy -> cameras; I checked it but nothing changed again.

edit: I forgot to mention: cheese works as expected. edit: for some reason, it's working fine after reboot. No upgrade was performed.

Aleksanaa commented 5 months ago

Please check if this is still the case. Working on 24.05.20240202.e92b601 with hyprland.

accelbread commented 5 months ago

Still not working for me on Gnome.

jtojnar commented 5 months ago

The symptoms described in https://github.com/NixOS/nixpkgs/issues/261217#issuecomment-1827940310 sound like they might stem from non-monotonic D-Bus serials. So maybe the issue I was having will be fixed by https://gitlab.gnome.org/GNOME/snapshot/-/merge_requests/194.

szw0407 commented 4 months ago

Has this issue been fixed yet in NixOS? If so, what caused this? I have the same error with snapshot on openSUSE Tumbleweed, GNOME 45. Thanks.

NixOS / nixpkgs
