Unsolved QtMultimedia, Camera Raspberry Pi - no cam detected, CameraBin error missing element 'multiflesink'

[dentist]

Hi,
I am trying a little embedded project for the first time and feel like running into a wall. Right now I'm only trying to get the 'Declarative Camera' example to work.

Setup:
Raspberry Pi 3 with 7" touch screen and camera
System: Yocto (using this really good guide and the qt5-image)

Added libomxil, gstreamer, gst-plugins-good, gst-plugins-bad, gst-plugins-base, gst-plugins-ugly, gst-openmax and gst-rtsp to the build as well as PACKAGECONFIG_append_pn-qtmultimedia = " gstreamer" .

Using the cross-compiler I always get an error.

qDebug() << QCameraInfo::availableCameras() returns an empty list

CameraBin error: "Missing element 'multifilesink' - check your GStreamer installation."

Anyone having the same trouble or an idea?
