You have two problems...the biggest: Failed to open video device /dev/video1: Permission denied

Fix:


chmod 777 /dev/video1 and / or zmfix -a

Second...you need to look at the WIKI for shared memory and how to fix the error.

What means 'exit status 11'?
And, although the message "'zmc -m 2' exited normally", the ZM is not showing any image. It is completly black.

@liviab
Your host path is wrong. Remove the http://IP_Address:Port

Change to:
Port: 8000
Remote Host Path: /axis-cgi/mjpg/video.cgi?camera=&resol

[liviab]

Cordel, thanks for your reply!!

But, it didn't work...
I think it is a problem about shared memory but I don't know what I can do to fix it.
Now the ZM has only the remote monitor. See what the file /var/log/messages says:

Do you know something about this problem?
