I'm trying to get zoneminder running using a USB Logitech QuickCam Pro 4000.

Ubuntu 8.10 (up to date with patches)
Installed zoneminder from the repositories (version 1.23.3)
I've installed camorama and am able to get a live stream, so in other words the WebCam has been recognised and is working.

I've increased the shared memory by adding
kernel.shmall = 134217728
kernel.shmmax = 134217728
to /etc/sysctl.conf and rebooting.

Code: Select all

cat /proc/sys/kernel/shmall 134217728
cat /proc/sys/kernel/shmmax 134217728

Here's what I'm getting in the log files

Google searches tell me increasing the shared memory will fix this problem but having done that I'm still stuck!

Any suggestions gratefully received, I've now reached the limit of my knowledge

I have that very same webcam and it works out of the box with the 1.24.1 install DVD. I'm using 8.04 so maybe that has something to do with it. I notice you show just about every other log file and setting, but how do you actually have it setup in Zoneminder? What resolution are you trying to get out of it? I'll reboot into Zoneminder and see if I can get you the settings that work for me.

Posted: **Wed Feb 25, 2009 2:49 pm**

Thanks for the reply.

I don't know where the webcam settings are stored so I'll list what displays in the setup page.

'General' Tab
name - logitech-cam
source - local
function - monitor
enabled - tick
rest are blank.

'Source' Tab
Davice path - /dev/video0
Device Channel - 0
Device format - PAL
Capture Palette - RGB24
Capture Width - 640
Capture Height - 480
rest are blank/default

Posted: **Wed Feb 25, 2009 3:01 pm**

Try and change if from PAL to AUTO or to NTSC. I don't see Pal mentioned in the zmu read out. You can also start out with 320x240 first and then go from there. It looks like you have it set for v4l, so just try and switch between PAL and what I mention and change it to 320x240 for now. The shared memory settings should allow higher, but just try those lower settings for now. I'm using Vista right now otherwise I would tell you my exact settings. I have an entire box full of usb webcam's from all the testing I've been doing

Tried auto here's the output (still not working)

Did you try 320x240? Also remove those memory entries you did and reboot it. I had no problem getting 320x240 so I'm not sure what's up with your setup.

Posted: **Wed Feb 25, 2009 5:33 pm**

Removed the shared memory settings from sysctl.conf changed the camera settings to 320 x 240 then rebooted the PC.

Still not working but the error message is slightly different now.

Today I tried uninstalling (purge) the repository version and build from source. It didn't go well! Ultimately it will only build if I compile ffmpeg from source and include swscale. However I don't want to do that as it may affect the mythtv frontend installed on the same PC.

So for the time being I would like to get the repository version working. Can anyone throw any light on this problem?

Thanks

I've performed a fresh install of Hardy on a different PC then installed ZoneMinder from the repositories. Unfortunately I only have the one webcam so couldn't try a different one. On this fresh install still getting the shared memory problems.

The webcam worked under cheese and camorama.

Any more suggestions out there?

Thanks

Given other people have the QuickCam 9000 working I bought one.

But still getting similar errors, so I'm assuming this is an OS related problem.

Performed a fresh install of Jaunty

But still getting same errors.....

I will get there!

Posted: **Sun Mar 29, 2009 10:01 pm**

What OS are you using, not sure what Jaunty is?
What drivers are being loaded?

I think you might have UVC drivers being loaded which is a Video 4 Linux 2 (V4L2) application and ZoneMinder <= 1.23.x can only handle V4L1. You might have to black list the UVC driver and install a V4L1 compatible driver.

I had the same issue. I upgrade from Ubuntu 8.10 to 9.04 and things finally work as they should and under 8.10 nothing was working. When upgrading make sure you re-edit the changes required in /etc/sysctl.conf .

NOTES:

to upgrade to 9.04 run "update-manager -d" IF update-manager is not installed, run "apt-get install update-manager"

ps: The official release date for 9.04 is April 23th but you can "force" an upgrade now ... at least, its going to make zoneminder work!
