MJPG-Streamer推流,将摄像头图像推送到http网页，

mjpeg推流,将摄像头推送到http网页

一、工具准备

1. Linux系统
2. usb摄像头

二、安装MJPG-Streamer

依赖的库和工具：

#库
sudo apt-get install libjpeg8-dev  #JPEG支持库（图像相关）

sudo apt-get install libv4l-dev   #4l是小写"L"（底层摄像头驱动的上层应用库）

#工具

#sudo apt-get install cmake  #下载编译工具（一般都有，没有需要下载）

#sudo apt-get install git    #（一般都有，没有需要下载）

安装与运行

# 方式包含但不限于以下两种

# 方式一    git

# pi@raspberrypi:~ $git clone  https://e.coding.net/fivecc/mjpg-streamer/mjpg-streamer.git

# 方式二    wget

pi@raspberrypi:~ $wget https://github.com/Five-great/mjpg-streamer/archive/master.zip

pi@raspberrypi:~ $unzip master.zip

#两种方式实现的效果大致相同

pi@raspberrypi:~ $ cd mjpg-*  # 进入mjpg-streamer-master文件夹

pi@raspberrypi:~/mjpg-streamer-master $ cd mjpg-*   # 进入mjpg-streamer-experimental文件夹

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

pi@raspberrypi:~/mjpg-streamer-master/mjpg-streamer-experimental $ sudo make install #安装

# 至此安装完毕

# 接下来就可以运行

pi@raspberrypi: ~ $  ./mjpg_streamer -i "./input_uvc.so -n  -r 1920x1080 " -o "./output_http.so -w ./www"

运行之后我们就可以在服务器的8080端口看到我们的摄像头啦

运行参数

mjpg_streamer

# mjpg_streamer本身只有两个主要参数

# -i：指定生成动态库

# input_uvc.so：用来处理输入的数据

# -o：指定生成另外一个动态库

# output_http.so：用来处理输出的数据，用来给到浏览器

# 注意：MJPG-Streamer还有一个插件叫做output_rtsp.so;其实它是浪得虚名，它并不能把我们的输入转换成rtsp协议输出
