It's a bit dark in my living room..

Hi,
I have zoneminder 1.25 set up on a CentOS 6.4 box. When I plug in the camera, I get...

Code: Select all

usb 1-1.2: new high speed USB device number 5 using ehci_hcd
usb 1-1.2: New USB device found, idVendor=046d, idProduct=08ce
usb 1-1.2: New USB device strings: Mfr=0, Product=0, SerialNumber=2

Linux video capture interface: v2.00
uvcvideo: Found UVC 1.00 device <unnamed> (046d:08ce)

Code: Select all

ls
/dev/video, I get /dev/video0, so I'm going on the basis that this is my camera.

So I add a monitor, and set it to /dev/video0. As source type, I choose 'local' first. Function is 'monitor'. Enabled, yes. FPS, I choose 14 to be on the safe side. In the sources tab, I select Video for Linux 2, Channel 0, Format PAL (I'm in the UK), and 320 x 240 as size.

Unfortunately, all I get is a black screen, and underneath, 'State: Idle - 0.00 fps'. In /var/log/messages, I get:

Code: Select all

And that's as far as I can get.

Can someone advise me where to go next? Thanks.

Bring the camera up in a browser or, for example, VLC and discover the properties.

The webcam is a v4l1 device. See bf65's response might help: http://www.zoneminder.com/forums/viewto ... 21&t=20510

v4l1compat.so I think is what is needed.
