Hello,
We have 2 USB cameras connected. They show up in the list with the same name. For the second one we use the instanceindex = 1 in setvideoinput function. Each one can be activated and works fine but when we try to work with both we can see the signal from the first one only.
Can you advice please.


Thank you,
Paruyr.

Yes, It was a a device driver problem. We installed the driver and everything is working now.
Thank you.

But each one separately works fine.

AMCAP should work (it uses DirectShow in order to capture frames, like ImageEn), for this reason it could be a device driver problem.

Yes. It hangs when try to get the signal from the second camera.

Thank you,
Paruyr

AMCAP also crashes?

Yes. I have 4 of them. Application works with 4 video sources at the same time. And it does work with all four sources. It happens with some usb cameras. I even tested it when cameras have different names and could recreate the problem. Somehow it depends on camera type or maybe driver ...? AND THE MOST INTERESTING THING IS that I tried the imageen demos - it has the same problem. I even tried with AMCAP.exe running it twice - one for each camera. It also crashes/freezes.

Hello,
do you have setup a TImageEnView for each camera?
