ZoneMinder Forums

Hi all!
This is my first post....

First, I readed the FAQ and zoneminder's documentation, but I cant start viewing my webcam.

Everything runs fine, I can use my webcam with Camstream, Xawtv and it is finely identified by v4l2. I use Fedora 10 with Zoneminder 1.23.3, I have mysql installed and running well and all other parts is ok too. My webcam is a C3 Tech (results of lsusb: 0ac8:307b Z-Star Microelectronics Corp. USB 1.1 Webcam) and I use with aMsn and others programs normaly.

The results of v4l-info:

I dont know what I can do with this "ERR ['zmc -d /dev/video0' exited abnormally, exit status 255]", and I cant even know if the error is with zoneminder or if my webcam is incompatible with it...

Can anyone help me, please?? I seek whole forum and I dont found anything to help me...

Thanks a lot!

Can anybody help me?? Please.....

Thanks

Have you given Apache the permision to access /dev/video0

Once you have validated your camera run zmu -d <device_path> -q -v to get a dump of the settings (note, you will have to additionally supply a username and password to zmu if you are running in authenticated mode). You can then enter these values into the video related options of the monitor configuration panel. The 'device_path' referred to here is the path to your video device file, for instance /dev/video0 etc. If 'zmu' gives you an error related to permissions run zmfix -a to make sure you can access all the video devices.

Yes, I already did. But my webcam dont work yet.....


Thanks!!

I had this message come up as well. I solved it by following a post on this forum and adding the following:


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

To /usr/bin/zmdc.pl, just before the my @daemons line.

Then restarted zoneminder.

Thanks for your help!! I have a x86_64 system, and I tried like you writed "/usr/lib/libv4l/v4l1compat.so", and didn't worked. Then, I changed to "/usr/lib64/libv4l/v4l1compat.so", and also didn't worked for me. But, the error changes, now I got:
