camera service is missing

[morkia]

I'm using Debian Jessie and dmesg | grep video returns:

[   22.280407] Linux video capture interface: v2.00
[   22.790704] uvcvideo: Found UVC 1.00 device Lenovo EasyCamera (13d3:5170)
[   22.796546] usbcore: registered new interface driver uvcvideo

The example compiles fine but upon launch i get a dialog telling me that the camera service is missing. I'm using Qt 5.5.0. Also I've installed Qt using the installer provided at the web site. I've tested my webcam with Cheese application and it works but QCameraInfo::availableCameras() returns nothing.

Am I the only person with this problem?

Hi
Might be a issue with it

Not that Debian is ubuntu but could be somewhat the same.

Hi,

Can you start your application with QT_DEBUG_PLUGINS=1 that might give some clues.

@mrjj It's the other way around ;) Ubuntu is a Debian derivative :)

@SGaist
hehe With the unity interface, it is sort of like the evil step child of debian.

@SGaist Ok I've put the environment variable you suggested in my Build Environment list. The application spat some output in which everything looks OK until this line:

defaultServiceProvider::requestService(): no service found for - "org.qt-project.qt.camera"

which looks like something that's querying the D-Bus for some services. I've checked every check box when I was installing Qt using the installer but It looks like it didn't install this or something else is needed but it's not documented.
