ZoneMinder Forums

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

UPDATE: there is a still picture when I go to "zones" so it seems to be receiving a picture just not displying it
(also noticed that this is in the v1.22.x forum)


tony

well I found the problem with my installation, it was an incorrectly set up cgi-bin directory!
I use a virtual server eg "http://zm.<domain>.com" and needed to add a cgi alias to the directory with the zm cgi programs in

tony

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]"

Still working on it ... )

I have just switch to IP wireless cameras Trendnet IP312W's and I get the same message:

zmwatch[3769].ERR [Can't get shared memory id '7a6d0002', 2: No such file or directory]

my cgi-bin directory is correct as well

See documentation


edit /etc/sysctl.conf and add the following lines (for 128meg shared mem)

kernel.shmall = 134217728
kernel.shmmax = 134217728

my current sysctl.conf values are:

kernel.shmmax = 68719476736
kernel.shmall = 4294967296


So I dont think the are the problem, they are much higher than documentations recommended values

are they too high aka you have more ram allocated than you have

kernel.shmmax = 68719476736

do you have 6.8gigs of ram

odd these are the default values on centos server 5.3

odd these are the default values on centos server 5.3

I am running Ubuntu 8.04 and ZM 1.22.3

and for the record ubuntu dosen't set it by defualt

now I am just getting the messages:

08/11/09 12:14:04.077973 zmdc[4389].INF ['zmc -m 1' starting at 09/08/11 12:1:04, pid = 4482]

08/11/09 12:14:01.574097 zmdc[4389].ERR ['zmc -m 2' exited abnormally, exit status 255]

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
