Hi all,

I am using Debian Lenny and ZM 1.24.0 compiled from sources. 1.24.2 did not play nice with FFMPEG so we had to downgrade to 1.24.0.
The same setup used to work perfectly with ZM 1.23.

Normal video cams work great with 1.24.0 now.

Our IP cams won't work, though. I verified that they work by wgetting images from the cams to our ZM host. Thus, subnetting, firewalls, access restrictions etc pp are not an issue.

When I try to access any IP cam with the settings known to work with 1.23, I only get a black rectangle. No text or any overlays, just a black box.

My /var/log/messages shows this:

Any and all feedback appreciated; we need this machine to work!

Thanks,

FWIW, I re-installed Debian Lenny & used the packages from unstable. That works.

I have a similar problem with one of my IP cameras. I've got a total of 5 IP cams. 4 are Trendnet IP501P and one wireless IP501W.

All 4 wired cameras work flawlessly. Since they are all wired IP cameras I get a constant ping of <1ms.

My one wireless camera however does not have such an ideal constant ping. Results range between 2-15ms, with 80% ranging between 2-6ms.

I have found at times I get the same error that the original poster was having and I'm wondering if it has something to do with the network side. I have just adjusted the FPS of the wireless camera down to a max of 5 fps. So maybe that will help. My other cams are recording at 10fps.

I've also read in some other posts that the "shared memory invalid" error was more of a browser error. Any other ideas?

Just had this yesterday on a debian box using the official packages.

During a bunch of updates, zoneminder got upgraded automatically and I didn't notice the installer CHANGED the events and images files back to the default of /usr/src/zoneminder/events ../images

I was getting those shared memory problems and nothing would initialise until I deleted those dirs and re-symlinked to the new ones.

ln -s /data/events

So, that would suggest a permissions problem or similar, possibly related to the upgrades?
