Multiple Cameras - Single image

[Mark Shahaf]

System: Suse 10.3 (kernel 2.6.22.5-31)
ZoneMinder: v1.23.3

I have 2 cameras attached to 2 USB ports. One is configured as /dev/video channel 0 and the second as /dev/video channel 1.

When watching the cameras from ZoneMinder I see the video from /dev/video0 on both!

Anybody struggled with such problem?

Thanks

Mark

They should actualy be two different video devices. Check your dmesg and you should see one assigned to video0 and the other video1.

I checked and they are. However the pictures I see are identical and are collected by video0. It seems that somehow video0 and video1 merged.

Can you post the webcam section of your dmesg please?
Not likely they merged as it don't work like that. It's more likely one has failed so your are left with one device.
Do you have these on seperate usb controlers?

Thanks!
