I have Ubuntu 8.10 OS with zoneminder installed. Zoneminder works but it can't show cameras. i have 0.0 fps in the monitor popup. The webcams work good with camorama and xawtv and they turn on led but when i use zm they don't work and the led is turned off.

Please can someone help me??
Thank you

£10 that it's rights.

1. Post the output from this command into this thread :
cat /var/log/syslog | tail

2. Try :
chmod 777 /dev/video0
/etc/init.d/zoneminder restart

3. Or try this :
adduder www-data video

4. And maybe this :
zmfix

5. Could even be memory, shmget :
echo 134217728 >/proc/sys/kernel/shmmax

btw, 2 and 5 won't survive a reboot.

i try all the command but not resolve the problem.

then i try to see the output of webcam on camorama. after the a little time, camorama close with error message "Unable to capture image" and the response of the log is libv4l2: error dequeuing buf: Errore di I/O.
my kernel release is 2.6.27-11 with ubuntu 8.10

what can i do?

Ouch. That's practically beyond my knowledge. But...

http://www.zoneminder.com/forums/viewto ... ae3103da64

The model of the camera and how it's connected wouldn't go a miss either.

Try shutting down zoneminder /etc/init.d/zoneminder stop and then remove/insert the camera. Then dump the tail end of the syslog. See what it says then.

That other thread may be the answer. :) Alot of the time the various errors, or truncated forms, can be typed straight into Google and will come up with something relevant.
