Single cam working, help configuring second on PV-143

stealth71 · Post by **stealth71** » Tue Jan 18, 2011 5:59 pm

I have a single BW camera that I've had working for a while now. I recently purchased a CBN DFL-20S and want to run both of these off the PV-143 until I can get a 4 chip PV-149.

I can get either camera to work in ZM independently, but not together. When I add the second input /dev/videoX device channel 2 the text is yellow not green and I get the same video stream from my other camera on this one when clicking in ZM.

I've tried changing both cameras to the same settings except "Device Channel" and I get the same results. Any help?

this is in my zmdc.log when I add the second camera:

Code: Select all

01/18/11 12:55:24.450010 zmdc[14614].INF ['zmc -d /dev/video1' stopping at 11/01/18 12:55:24]

I used the install script which adjust the shared memory.

zmu -d /dev/video1 -q -v

I found some other related posts and got it working.

I ended up setting CAPTURES_PER_FRAME to 2 and both are working. This is under Options>Config

This seems to be required for any capture card sharing a single chip.
