If its and NTSC/PAL coax output, just plug it into an old analog TV and verify the signal output is good first. Even connecting the camera to working windows software will do for output signal verification. Many cameras are easy to damage, from bumps or drops..... If it's a usb webcam, maybe you have a channel input to something that works generically? The point is to make sure valid video signal is emminating from the camera first. Next I use some very simple program and syntax to make sure it's working on the computer. Use something simple and generic. I currrently use this syntax with mplayer: mplayer -fps 15 tv:// -tv driver=v4l2:device=/dev/v4l/video1 There are a multitude of issues that can break any given camera/package combo, and many are hard to track down. It can be use flag, newer versions of software fail, kernel issue, command line options, ... just to mention a few. Manually parse through /dev/v4l/video* and find where your devices is connected to the kernel. good hunting, hth, James
