I am trying to simultaneously use three USB cameras with jetson NX. I am using jetcam package and logitech C270 cameras. It works perfect either with two USB cameras or two CSI cameras only. When trying with three cameras, below error occurs:
File “/usr/local/lib/python3.6/dist-packages/jetcam-0.0.0-py3.6.egg/jetcam/usb_camera.py”, line 28, in init
RuntimeError: Could not initialize camera. Please see error trace.
I used an usb hub to connect these cameras. Tried using hub with its own power supply as well. Same error persists.
Do i have use ROS usb cam packages to do this? I am coding my project in python so using jetcam libraries would be easy. Would be helpful if anyone could help.
