Unable to set/change Camera in settings

[anvit]

I'm unable to set the camera in the settings, and it just shows me an empty dropdown despite having a webcam connected.

Things I've tried:

• I have set the driver Camera driver to None (still image) and then back to Qt Multimedia, restarted mgba, restarted the computer.
• I've tried running this on the current as well as the development builds but both have the same behaviour.
• I've tried running the 0.9.3 version from snap which also had the same behaviour.
• Trying to run roms that use the camera anyway makes it show what seems like a stock webcam photo.
• I'm running this on a Ubuntu 22.04, and I've installed qtcreator qtbase5-dev qt5-qmake libqt5multimedia5 but that did not result in any changes.
• Changing the audio driver to Qt Multimedia and video to Qt makes loading a rom crash.
• Under the default settings the rom loads up and runs fine, which makes me think the issue is specific to Qt.
• I was unable to find any additional details in the README, the website, or the forum about if I need to install a specific Qt package, or if mgba uses qt6 instead of qt5.

Additional details:

• Running this on a System76 Galga Pro laptop.
• I've tried this with the built in webcam (Bisoncam nb pro), Logitech HD C920, as well as a Fujifilm X-T5. All of these are detected by OS and I'm able to access the video feed in other applications.
• I'm primarily testing this with Photo! but I've tried other roms that also use the camera.
