[deathguppie]

I have a logitech usb webcam I am trying to test zoneminder with, the camera works, but does not show up in zoneminder.
here is the last few lines of zmdc.log

This is the part I figure is wrong in zmwatch.log

Code: Select all

12/05/11 20:34:32.371533 zmwatch[1479].ERR [Can't open memory map file '/dev/shm/zm.mmap.2': No such file or directory]

I found a reference to the issue on the web.

zoneminder package not ready to use /run

But it looks as if /run/shm already exists, owned by root with some pulse audio usage. ..
How do I fix this issue?

[leeroybrown]

Do you have the mode set to PAL ? My Logitech orbit will only work when set to PAL and does not when set to NTSC.

[deathguppie]

Yes it's set to pal.. the issue is this memory thing there should be a fi
le for am in /run/

[deathguppie]

so I set the buffer size and alert image size to low values to see if that would help .. restarted zoneminder and get this

ok.. wow.. I've tried 3 different cameras, all of them work with xawtv and nothing.

I'm starting to realize that zoneminder for all practical purposes simply does not work. Perl is a deep well as it is, and trying to figure out why it isn't working is turning out to be almost impossible. Memory is not mapping that much I can see.. but why?

No help and running out of things to try..

[deathguppie]

Figured it out. The problem was that the ubuntu package does not install perl mmap. (though it claims to) that must be done by hand. Also since I had configured the cameras prior to having mmap installed, I had to delete the existing monitors and start over before they started working.

It looks like I may have the same problem on Mythbuntu 11.10, I get this error

and also

What is the actual package missing? I've tried looking for perl-mmap but it doesn't exist.
