树莓派+USB摄像头进行网络监控—MJPG-Streamer

一、硬件材料

1、树莓派3或3B+

2、电脑

3、USB摄像头

二、检查树莓派是否已加载USB摄像头

输入命令行

also usb

或者输入

ls /dev

三、安装NJPG-Streamer

依次输入命令行

pi@raspberrypi:~ $ sudo apt-get install cmake libjpeg8-dev

pi@raspberrypi:~ $ wget /jacksonliam/mjpg-streamer/archive/master.zip

pi@raspberrypi:~ $ unzip master.zip

pi@raspberrypi:~ $ cd mjpg-

pi@raspberrypi:~/mjpg-streamer-master $ cd mjpg-*

pi@raspberrypi:~/mjpg-streamer-master/mjpg-streamer-experimental $ make

pi@raspberrypi:~/mjpg-streamer-master/mjpg-streamer-experimentalsudo make install

pi@raspberrypi:~/mjpg-streamer-master/mjpg-streamer-experimental cd $home

pi@raspberrypi:~ $

四、启动MJPG-Streamer

输入命令，启动mjpg-Streamer

pi@raspberrypi: ~ $ /usr/local/bin/mjpg_streamer -i “/usr/local/lib/mjpg-streamer/input_uvc.so -n -f 30 -r 1280x720” -o “/usr/local/lib/mjpg-streamer/output_http.so -p 8080 -w /usr/local/share/mjpg-streamer/www”

五、参数说明

-i “/usr/local/lib/mjpg-streamer/input_uvc.so -n -f 30 -r 1280x720”

-i 输入

input_uvc.so：UVC输入组件

-f 30 ：表示30帧-r 1280*720：分辨率-y ：YUV格式输入（有卡顿），不加表示MJPG输入（需要摄像头支持）

-o “/usr/local/lib/mjpg-streamer/output_http.so -p 8080 -w /usr/local/share/mjpg-streamer/www”

-o 输出output_http.so：网页输出组件-w www : 网页输出-p 8080：端口 8080-d 1000： 时间1S
