1、将USB摄像头插上，查看是否找到设备，输入：
wp@ubuntu:/home/$ ls /dev/video*
/dev/video0
2、安装必要的软件集：
sudo apt-get install subversion libv4l-dev libjpeg62-dev imagemagick
3、下载mipg-streamer软件，编译并安装：
git clone https://github.com/shrkey/mjpg-streamer
cd mjpg-streamer/mjpg-streamer
make clean all
sudo make install
ps：重新编译前，需要执行
make clean（相对make)
make uninstall（相对make install）
4、开启视频服务器
wp@ubuntu:/home/mjpg-streamer/mjpg-streamer$ ./start.sh

( 注意：在ubuntu 里面运行 ，这里面的错误可以不用理会 )
或者在profile文件中，添加如下代码，将其添加到环境变量中。
sudo nano /etc/proflie
export LD_LIBRARY_PATH=/usr/local/lib
