Ubuntu 8.10, ZM 1.23.3-3 and no image --Now Bad image

Cartsy · Post by **Cartsy** » Thu Dec 04, 2008 12:05 am

I'm using Ubuntu 8.10 and Zoneminder 1.23.3-3 and can't get an image out of it.

When I type:

~$ zmu -d /dev/video1 -q -v 

Aborted

But if I use sudo:

Code: Select all

~$ sudo zmu -d /dev/video1 -q -v

My webcam works fine with other programs but not with Zoneminder..

What should I do?

Check that zmfix has the setuid and if not:
sudo chmod 4755 /usr/bin/zmfix

Thanks, but no help. Source stays red.

Should I try an older version of ZM?

Edit: I think I have rights to /dev/video1 because "cat /dev/video1" works fine.

Edit2: I did nothing and the source seems to be yellow now. Still no picture.

As a user, try 'zmfix' and tell me what it returns. After it runs, try 'ls /dev/vid* -lah' and tell me what that returns.

Cartsy · Post by **Cartsy** » Fri Dec 05, 2008 6:06 pm

zmfix returns nothing.

ls /dev/vid* -lah returns:
crw-rw----+ 1 root video 81, 0 2008-12-05 20:00 /dev/video0
crw-rw-rw-+ 1 root video 81, 0 2008-12-05 20:00 /dev/video1

I did that shared memory thing and now /var/log/syslog.log says:

Edit: And suddenly it starts working. I did nothing. Just few clicks with those zone things in Watch window. Sometimes source is red, sometimes it might be yellow..

This is how it "works": http://e.imagehost.org/view/0288/eiei It takes this crappy image every 10 seconds.

Edit2: Doesn't help if I change the resolution of the cam.

Edit3: My cam is Labtec webcam pro. Any suggestions of cheap cams that should work with ZM?

Hello Cartsy,

Did you get you webcam to work in the end? I have experienced what looks like exactly the same problem except that my webcams used to work. I had Zoneminder running perfectly under openSuse but have just migrated to Ubuntu 8.10 and now I get the same error messages as you.

The cameras work when using other programs e.g. xawtv.

The cameras I have came in the "Creative - Webcam Vista Skype Dual Pack" from PC World (lsusb shows it as 041e:405f Creative Technology, Ltd).

We're three with the same problem.

My log file is showing the same messages that the Cartsy's is.
My camera also works fine with other programs, such as cheese and xawtv.

By the way, I'm using ZoneMinder-1.24.0 and Fedora 10.

Anyone can help us? ^^

I'm joining this club.. in case you didn't see my previous posts

so, we're four. heheh

Because I'm out of ideas i'm just going to ask what modules you are using for your cams? Could a faulty module do all this?

I tried to compile gspca from a source but it didn't work because it can't find semaphore.h for some reason.

liviab · Post by **liviab** » Thu Jan 29, 2009 1:59 pm

The command dmesg is showing:

Linux video capture interface: v2.00
gspca: main v2.2.0 registered
gspca: probing 041e:4051
zc3xx: Sensor Tas5130 (VF0250)
gspca: probe ok
usbcore: registered new interface driver zc3xx
zc3xx: registered

So I think that it is gspca with the module zc3xx.

Looks like a permission issue. I usually have to add the user that ZoneMinder is running as (www-data) to the video group. Have you tried this?

Code: Select all

sudo usermod -a -G video www-data

liviab · Post by **liviab** » Thu Jan 29, 2009 2:17 pm

It doesn't work...

Code: Select all

[root@livia ~]# usermod -a -G video www-data
usermod: user www-data does not exist

Ergh. The original poster is using Ubuntu, on which apache runs as www-data. Which distro are you using? Just substitute www-data for the user that apache (or ZoneMinder) is running as.

Yeah same here and the same errors as you...

Code: Select all

So it could have something to do with the module.. ?
