Hey there,
I'm currently working on project that can detect specific letters and colors. In order to do that, I'll need 2 USB Cameras getting live video, and taking photos. I've tried to implement a simple script to just open the live video from both of them, but it doesn't work. There you have the script:
When I start the code, I don't get any visual feedback from the câmeras and i get just like this :
I've tried to modify the code above to read the video from just one camera and it worked perfectly, for both of them.
Setup:
Raspberry Pi 4 B - 4GB
Raspberry Pi OS - 64 bits
Thonny Python - IDE
