1) First, you need to prepare a USB camera that supports UVC protocol as shown in the
figure below or similar, and then insert the USB camera into the USB port of the Orange
Pi development board
2) You can see that the USB camera's device node information is /dev/video0 through the
v4l2-ctl command
orangepi@orangepi:~$ v4l2-ctl --list-devices
Q8 HD Webcam: Q8 HD Webcam (usb-fc880000.usb-1):
/dev/video0
/dev/video1
/dev/media0
Note that the l in v4l2 is a lowercase letter l, not the number 1.
In addition, the serial number of the video is not necessarily video0, please refer
to what you actually see.
