mjpg-streamer 是一个开源的网络视频流服务器，本文使用UVC摄像头在UBUNTU18.04上建立一个测试环境。
1.安装环境依赖库
sudo apt-get install subversion libv4l-dev libjpeg62-dev imagemagick cmake subversion
?2.编译并安装mjpeg-streamer源码，注意要切换到root模式编译，否则安装失败。
git clone https://github.com/vcsy1994/mjpg-streamer.git
cd mjpg-streamer
make clean && make all && make installroot@czl-RedmiBook-14:/home/czl/Workspace/mjpg-streamer# make clean && make all && make install
[ ! -f _build/Makefile ] || make -C _build clean
rm -f mjpg_streamer *.so
[ -d _build ] || mkdir _build
[ -f _build/Makefile ] || (cd _build && cmake -DCMAKE_BUILD_TYPE=Release ..)

3.启动mjpeg_streamer并且启动http服务器。
mjpeg_streamer启动后内部会继续启动一个http server，用来响应客户端连接.
./mjpg_streamer -i "./input_uvc.so -d /dev/video0 -u -f 30" -o "./output_http.so -w ./www"
?4.在浏览器中测试,浏览器中输入以下网址，可以直接打开远程UVC摄像头.查看MJPEG 数据。
http://127.0.0.1:8080/
或者输入如下URL，直接看视频:
