Dear Hung, Edwin,

This forum is concerned with Inference Engine and Model Optimizer (OpenVino). Usb camera falls into the OpenCV category - please post your question on the following forum instead:

https://answers.opencv.org/questions/

Also there has been some previous IDZ discussion on USB Cameras and OpenVino.

Hope it helps,

Thanks !

I don't see any evidence of problem specifically with camera. The program just crashed, more details are needed. Please try to build the program in debug mode and run it with GDB to get a stacktrace.
