I can't get zoneminder working on my fresh Ubuntu 64bit install with ACTi IP cameras.
I've followed the build and install guides on the wiki several times with the same results.
Zoneminder and ffmpeg where built from the svn repositories. I even went back to the
ffmpeg 0.5 and zoneminder 1.24.1 bases but no luck there either.

zmc is crashing with signal 8 (floating point exception). At this point I'm not sure if it's a shared memory, zmc, 64 bit O/S or combination.
When I turn on debug I'm seeing that the capture daemon does grab frames but gets errors trying to decode the frame. Am I correct to assume if zmc is getting frames
then shared memory is working?
ffmpeg works capturing video streams from the camera using rtsp and I can playback with mplayer.

I'm running out of ideas. does anyone out there have any clues whats going on here?
Any help and/or suggestions would be greatly appreciated.

Thank you.

Errors in the apache log but I think these are just an artifact of the capture daemon barfing:

What are your settings in ZM far the camera?
Did you use the Acti preset when you set it up?

Yes sir. I did use ACTi presets.

I think for Acti there should be a path defined, your zmu output shows it missing, though I don't have a bunch of experience with these, actually almost nill.

Watch this thread it may help:
http://www.zoneminder.com/forums/viewtopic.php?t=14024

I don't have an acti cam here to check for the path.

Well that's what I thought as well. Version 1.24.1 preset for the ACTi had a remote host sub path set to '/track'. The remote host sub path went away for this preset in the 1.24.2 version. I had concerns about this and posted questions for clarification. From the forum replies it sounds like it's not needed any more.

If someone can tell me how to check the path I'd be happy to do it and post the results. None of this information is included in any of the ACTi documentation. The docs say I have to contact a sales rep and sign an NDA in order to see the API (boo!).

BTW, when I run zmu on the same camera from my 32 bit install 1.24.2 which does work there is no path there either
