Are you certain that the camera is working? If its and NTSC/PAL |
9 |
coax output, just plug it into an old analog TV and verify the |
10 |
signal output is good first. Even connecting the camera to working |
11 |
windows software will do for output signal verification. Many |
12 |
cameras are easy to damage, from bumps or drops..... |

If it's a usb webcam, maybe you have a channel input to something |
16 |
that works generically? The point is to make sure valid video |
17 |
signal is emminating from the camera first. |

Next I use some very simple program and syntax to make sure it's |
20 |
working on the computer. Use something simple and generic. I currrently |
21 |
use this syntax with mplayer: |
22 |
|
23 |
mplayer -fps 15 tv:// -tv driver=v4l2:device=/dev/v4l/video1 |

There are a multitude of issues that can break any given camera/package |
27 |
combo, and many are hard to track down. It can be use flag, newer versions |
28 |
of software fail, kernel issue, command line options, ... |
29 |
just to mention a few. |
30 |
|
31 |
Manually parse through /dev/v4l/video* and find where your devices is |
32 |
connected to the kernel. |
