But I can managed to get a picture of whitenoise or something like that - but not a image in generel to se what's happening with on the CAM.

Its just green image or white noise - so I think it something about the setup and settings for the CAM. Probing after the CAM cannot find it - But I've testet it in my laptop and runs fine there!

Code: Select all

Device Path	/dev/video0
Capture Method	Video For Linux version 2
Enheds Kanal	0
Enheds Format	 PAL
Capture Palette	 JPEG
Capture Width (pixels)	 320
Capture Height (pixels) 280	
Preserve Aspect Ratio	
Orientation	   Normal

Can someone tell me if this is not possible or something else is wropng/missing here ????

TIA
