[sl_oc::video::VideoCapture] ERROR: Cannot open ‘/dev/video2’: [16] Device or resource busy
Cannot open camera video capture
See verbosity level for more details.

Does any one know how i can resolve this issue?

Hi @abiodun
welcome to the Stereolabs community.

Does the example work if you launch it with sudo?

What camera model are you using?
What type of host device?
Can you open the camera with cheese or guvcview?
Can you post the output of the command lsusb -d 2b03: and lsusb -d 2b03: -v?

The camera model is zed2i
the host is a laptop running ubuntu
I tried opening the camera with both app, but the apps were picking feeds from the laptop web cam
the output of the commands are:

The camera seems correctly detected.
Did you install the udev rules?
