This software is great. I have a video capture card with 4 inputs. If I plug the first camera into port 0, it works great. But, when I add an additional camera to port #1, I get no picture. I tried for 2 and 3 with no luck. Any of how I can add more cameras? Thanks.

cd to /dev and type 'ls vi*' and tell us what you see. If you have /dev/video0 to /dev/video4 you do it one way. If you only have /dev/video0 you do it another way. Depending on the card, you may also need a modprobe line.

input=0, input=1,input=2,input=3

or Device Channel 0(1,2,3) for ZM

root@cctv:/dev# ls -l vid*
crw-rw-rw- 1 root video 81, 0 2007-06-01 10:26 video0


Sorry Boycho, I don't understand what you are saying there. Is it a setting in the GUI?

FOR ZM
Tab Source:
for cam 1 - Device Path /dev/video0
Device Channel 0

for cam 2 - Device Path /dev/video0
Device Channel 1

for cam 3 - Device Path /dev/video0
Device Channel 2

for cam 4 - Device Path /dev/video0
Device Channel 3

FOR Mplayer
-tv device=/dev/video0:input=(0 , or 1 , or 2 , or 3)

Oops, I had /dev/video instead of /dev/video0 for the 2nd camera. Works great now!

Thanks for your help.
