## XDG Desktop Portal
Snapshot uses the camera portal to request camera access. There are desktop environment specific implementations for it, thus ensure to have the matching one installed:

* [Gnome](https://gitlab.gnome.org/GNOME/xdg-desktop-portal-gnome)
* [KDE](https://github.com/KDE/xdg-desktop-portal-kde)
* [wlroots](https://github.com/emersion/xdg-desktop-portal-wlr) (Sway, Phosh, Hyprland etc.)

If Snapshot can't find any devices, you can check camera permissions in various ways, a simple one being [Flatseal](https://flathub.org/apps/com.github.tchx84.Flatseal).

## Gstreamer
Snapshot uses `GstPipeWire` components. In order to list available cameras and additional information about them, look for entries that contain `gst-launch-1.0 pipewiresrc` when running:
