Camera image not detected on Linux

[Octopus1348]

Is there an existing issue for this?

• [x] I have searched the existing issues

Affected Build(s)

Nightly 2071 and Canary 2741

Description of Issue

When I set the Camera Image Source to "System Camera (qt)", it doesn't work in the emulation and when I click to preview, it just says "Cannot load the camera". Plus, I can't set "Camera" to anything other than <Default>

My laptop camera works in other programs otherwise.

Expected Behavior

When I set to system camera, it should successfully use the system camera.

Reproduction Steps

1. Go to Emulation > Configure > System > Camera
2. Set "Configure camera" to Front on a system that has a front camera.
3. Under Configuration, set "Camera Image Source" to "System Camera (qt)"
4. Try in an emulated software or select "Click to preview"
