Description of problem:

Cheese as installed through Fedora's official Flatpak repo (https://registry.fedoraproject.org/) is unable to find the attached cameras.

How reproducible:

Every time I launch this installation of cheese. Installations through `dnf` and the 3rd party flathub are both fine.


Steps to Reproduce:
1. flatpak remote-add --if-not-exists fedora oci+https://registry.fedoraproject.org
2. flatpak install fedora org.gnome.cheese
3. flatpak run org.gnome.Cheese

Actual results:

Message saying "No device found". No devices listed in the preferences.


Expected results:

Preview image in the main window. Camera devices listed in the preferences.

Still an issue as of today. The version from Flathub works perfectly fine.

Comment 2 Timothée Ravier 2022-06-20 15:53:55 UTC
This has also been discussed in https://discussion.fedoraproject.org/t/debugging-webcam-microphone-in-cheese-flatpak/34189

If the one from Flathub works and the one from Fedora does not then someone should compare the permissions in the manifests:
- https://github.com/flathub/org.gnome.Cheese/blob/master/org.gnome.Cheese.yml
- https://src.fedoraproject.org/flatpaks/cheese

Comment 3 ccouzens 2022-06-20 22:08:47 UTC
I believe the permissions are the same:

flathub's:

```
flatpak info --show-permissions org.gnome.Cheese
[Context]
shared=ipc;
sockets=x11;wayland;pulseaudio;fallback-x11;
devices=all;
filesystems=xdg-pictures;xdg-videos;
```

Fedora's:
```
flatpak info --show-permissions org.gnome.Cheese
[Context]
shared=ipc;
sockets=x11;wayland;pulseaudio;fallback-x11;
devices=all;
filesystems=xdg-pictures;xdg-videos;
```

Assuming I'm reading the manifest correctly they are also the same there:
https://github.com/flathub/org.gnome.Cheese/blob/master/org.gnome.Cheese.yml#L7-L14
https://src.fedoraproject.org/flatpaks/cheese/blob/stable/f/container.yaml#_9-16

I confirm the flathub version still shows the webcam feed, and the fedora-flatpak version still shows the "No device found" message.

I can get bash inside the cheese flatpak. If you tell me what to look for inside the container I can report back the difference.

Comment 4 Timothée Ravier 2022-06-21 16:23:26 UTC
I don't really know how Cheese works but removing access from a working Flatpak until it breaks will get you started.
Maybe the Runtime permissions are different between the Fedora Platform one and the Flatpak GNOME one?
