Acquiring Live Feed from Multiple Webcams

[rsalazar]

Hello,

I started this post cause I can't find any solution to my problem.

I have this project of using webcam as a barcode scanner on a simple power on test. The testing has 4 slots, which means it can test up to 4 units at a time.

Using the camera as a scanner is already done. What I'm having trouble are the cameras, they are not opening their feeds. Only two of them opens, and the other 2 don't have their image.

I've attached the VIs that emulates what I need.

and below is a screenshot on what I encounter.

NOTE: I'm using one subvi for 4 cameras. I set that VI its reentrancy as "Shared Clone reentrant"

Can anyone help on this, or maybe correct me if I've done anything wrong on the code.
