1 year ago For study Running the Live Camera Recognition Demo, I plugged a USB camera into the jetson Xavier NX board and ran
. /imagenet.py csi://0without the expected results. But as you can see from the output on the command line, the video stream has been created.
@WangQingchen123 csi://0 is for using MIPI CSI camera, for USB camera you would start it with something like /dev/video0
