I am running Ubuntu 8.04 and ZM 1.22.3 using USB WebCam. The camera shows video when using local program like camorama. However, no image is visible when using zoneminder. The error showing on zmwatch.log is shared memory not valid
Looked for at similar posting relate to shared memory and shared memory not valid but could not find a solution that is relevant to my case.
Here are the outputs from different commands

Try
sudo adduser www-data video
This seamed to help me but now I get "Shared data not initialised by capture daemon, some query functions may not be available or produce invalid results]"

The way that I was able to fix this issue was by chmod'ing /dev/video0 with 666
ie chmod 666 /dev/video0
may not be the most secure way to do it...but its working
...
[EDIT]
but that is just a quick dirty fix...my real issue was that i didnt have some permissions set right. After following the directions in the Wiki related to installing by .deb it worked fine. Now to address my USB bus issues only allowing one camera at a time
ie chmod 666 /dev/video0
