I have a usb camera connected to my raspberry pi 2, I can view its output on /dev/video0 from the command line. 

Under HomeGenie settings > camera input I have /dev/video0 | 320x240 | 1 and the camera enabled, there's a camera icon on the top of the page next to a zwave icon (it is dimmer)

I'd like to add my camera display to the dashboard but can't figure out how, what do I do next?

Thanks

edit - it's a raspi 2

I see the same error in my logs, is there something I should add to my path, or symlink somewhere?

[email protected]:/usr/local/bin/homegenie $ locate CameraCaptureV4L.so
/usr/local/bin/homegenie/lib/mig/libCameraCaptureV4L.so
/usr/local/bin/homegenie/lib/mig/v4l/debian64_libCameraCaptureV4L.so
/usr/local/bin/homegenie/lib/mig/v4l/debian64_libCameraCaptureV4L.so.gd3
/usr/local/bin/homegenie/lib/mig/v4l/raspbian_libCameraCaptureV4L.so

Have you activated the Generic IP program in the Programs section. You then configure the IP Program widget and add it to your dashboard to view it's output.

It's a usb camera connected to the pi, not a remote device, do I have to set up a webcam server on the pi and then connect to that?  Or can I connect directly to /dev/video0?

did a complete reinstall from scratsh. no trace of CameraCaptureV4L.so
But found /usr/local/bin/homegenie/lib/mig/v4l/raspbian_libCameraCaptureV4L.so
and /usr/local/bin/homegenie/lib/mig/libCameraCaptureV4L.so, witch are identical.

What is missing ?

I installed motion on the raspi and can view it in a web browser and it works, but when I use that url as the address in homegenie it just says "connecting to camera" forever, I've also tried http://127.0.0.1:8081/image.jpg, but that doesn't work either.

Try http://yourcameraipaddress:portnumber/snapshot.cgi in the in the generic ip camera widget and the username and password below in the relevant boxes if they apply for your camera.

Made it work perfectly with Motion.

The image is from a CGI offered by the motion developper that i had to compile.
   Name : nph-mjgrab

The motion detection is done by calling a script in motion.conf
  # Command to be executed when an event starts. (default: none)
  # An event starts at first motion detected after a period of no motion defined by event_gap
  on_event_start /Home-Automation/OnEventStart.sh

The sh command is
  curl http://localhost:8080/api/Media.IpCamera/1/Camera.MotionDetected
