Camera Example - no service found

feniks_fire

So, when I try run "Camera Example" I have this error on my terminal in raspberry:

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

Of course I install many gstreamer libraries but nothing happens and I don't have many left hard space on this memory card so I need help.
Anyone know what exactly library I need to install?

Strange, that looks pretty complete. How are you connecting your camera ?

feniks_fire

Well, I connect camera into my usb from rpi. I use vncviewer to get raspberry display on my ubuntu and then I run this program.

SGaist

What brand of camera is it ?

X-calibur like this: https://www.evertek.com/viewpart.asp?auto=43020&cpc=RECOM

How did you install Qt on your Pi ?
Which version is it ?

feniks_fire

Well, I had a short break...
First of all I forget tell that I using cross-compiling for my raspberry.
I installed only few Qt modules for Pi, which this example uses, because as I said I don't have many free disk space.
So, these are my Qt modules installed by synaptic:
version:

5.3.2+dfsg+4+rpi1

Modules:

libqt5core5a
libqt5dbus5
libqt5gui5
libqt5network5
libqt5opengl5
libqt5widgets5
libqt5multimedia5
libqt5multimediawidgets5

Maybe this is my fault but I don't see any place where I can download the newest Qt for 32-bit systems.
But all other examples which I tested, seem to be fine.

Did you check whether the gstreamer backend was properly built and installed ?
