Okay a new thread with new errors. A fresh install of Ubuntu 8.10 32bit and zm1.23.3 from source. Configured with:

./configure --prefix=/ZoneMinder --with-cgidir=/usr/lib/cgi-bin --with-webdir=/www/html/zm --with-webuser=www-data --with-webgroup=www-data

When adding a new usb-camera (ID 046d:08da Logitech, Inc. QuickCam Messanger) using gspca_zc3xx and gspca_main modules (ubuntu installed them.) I get these errors to syslog:

Looks like a driver issue,
What is at the tail end of dmesg when you have ZM running?
What happens if you run xawtx and capture jpeg snapshots from it?

Yea I've been thinking about that too.. because it's starting to be the only thing what I can't change in any way.. i think..

dmesg doesn't output anything, syslog says:

Code: Select all

Feb  1 12:03:40 router zmdc[3942]: ERR ['zmc -d /dev/video0' exited abnormally, exit status 255]

And ZM's own logs:

Code: Select all

02/01/09 12:02:17.685740 zmwatch[3975].INF [Restarting capture daemon for New, time since last capture 8 seconds (1233482537-1233482529)]

02/01/09 12:02:27.777958 zmwatch[3975].ERR [Can't get shared memory id '7a6d0006', 6: No such file or directory]

And now the killblow.. xawtv says like this when trying to capture a still image:

Code: Select all

libv4l2: error setting pixformat: Invalid argument

ioctl: VIDIOC_REQBUFS(count=0;type=VIDEO_CAPTURE;memory=MMAP): Device or resource busy
libv4l2: error requesting 4 buffers: Device or resource busy
v4l2: read: Device or resource busy

I didn't change anything from xawtv.. just installed it from the repository.

I have the same problem here.

After a lot of time wasted, I think I found a solution (Ubuntu 8.10 x64):
edit the file /usr/bin/zmdc.pl (#sudo gedit /usr/bin/zmdc.pl)
insert the following line:

Code: Select all

$ENV{LD_PRELOAD} = '/usr/lib/libv4l/v4l1compat.so';

this line should be inserted just before the "my @daemons = (" line

just restart zoneminder and it magically works !

wisekki · Post by **wisekki** » Sun Apr 05, 2009 4:14 pm

I confirm this.. it works after adding that line! Very nice work indeed

So you didn't waste any time.. hopefully this will be added to 1.24..

I ended up with the same problem. Here are my steps in case it helps anyone:

Running Ubuntu 9.04, I installed the zoneminder v1.23.3 package with Synaptic.

In order to have my QuickCam Connect (046d:089d) I had to upgrade to kernel 2.6.29 (solution here: http://forum.ubuntu-fr.org/viewtopic.php?id=262280)

I then had the "zmc -d /dev/video0' exited abnormally, exit status 255" / "Capture failure for frame 2: Invalid argument" problem, which I solved by preloading v4l1compat.so as stated two posts above.

Thanks a lot, you made my day!!

Hi,

I'm also getting the floating point exception. I tried adding the line
$ENV{LD_PRELOAD} = '/usr/lib/libv4l/v4l1compat.so';
to the perl script.

Still getting the same error.

My /var/log/messages:

I'm not able to start nph-zms deamon also.

Any help in this regard will be appreciated.
Thanks.

I'm also getting the floating point crash with or without the suggested fix.

Hello

Try to access your camera from the Linux host with ZoneMinder. 'Can't connect to remote camera: No route to host' indicates that it isn't reachable.

I followed this post, and it solved my problems. I've been through the FAQ numerous times, tweaked shared memory.... I even gave up on my Fedora box and built and Ubuntu machine last, just to have the same problems with my Labtec Webcam Pro. I am temporarily using this cheap camera to check out zoneminder. I switched back to troubleshooting the Fedora box, and then found this post, and just as I was about to completely give up on this app! Thanks!

I'm running Zoneminder 1.24.2, installed by yum.
Device Path /dev/video0
Capture Method v4l2
