hi

Iam usong opencv to process images
cap = cv2.VideoCapture(’/dev/video{}’.format(int(INPUT_PATH)))
is just working fine for me .
But iam unable to open more that 3 cameras at a time on my jetson nano, which has 4 usb ports. i have tried different combination and only 2 work at a time
Any pointers would help

Hi,
Do you use USB3 cameras? If you use USB2 cameras, it may hit bandwidth limitation. Please refer to this post:
