>root@orangepipc:~# ls /dev/video0
/dev/video0
然后安装mjpg_streamer
```
pi@raspberrypi:~ sudo apt-get install subversion gcc make
pi@raspberrypi:~ sudo apt-get install libv4l-dev #armbian貌似不可以
pi@raspberrypi:~ sudo apt-get install libjpeg62-dev #armbian貌似不可以
pi@raspberrypi:~ sudo apt-get install libjpeg8-dev
pi@raspberrypi:~ sudo apt-get install imagemagick
pi@raspberrypi:~ $ sudo apt-get install cmake libjpeg8-dev libjpeg62-turbo-dev
pi@raspberrypi:~ $ wget https://github.com/Five-great/mjpg-streamer/archive/master.zip
pi@raspberrypi:~ $ unzip mjpg-streamer-master.zip
pi@raspberrypi:~ $ cd mjp*g-*
pi@raspberrypi:~/mjpg-streamer-master $ cd mjpg-*
pi@raspberrypi:~/mjpg-streamer-master $ make clean all
pi@raspberrypi:~/mjpg-streamer-master/mjpg-streamer-experimental $ make
