mv master mjpg-streamer-master.zip

编译mjpg-streamer

安装cmake

sudo apt-get install cmake

切换到mjpg的路径下

cd 目录/mjpg-streamer-master/mjpg-streamer-experimental
sudo make clean all

安装mjpg-streamer

sudo cp mjpg_streamer /usr/local/bin
sudo cp output_http.so input_uvc.so /usr/local/lib/
sudo cp -R www /usr/local/www

启动mjpg_streamer

方法1

LD_LIBRARY_PATH=/usr/local/lib mjpg_streamer -i "input_uvc.so" -o "output_http.so -w /usr/local/www"

方法2

LD_LIBRARY_PATH=/usr/local/lib mjpg_streamer -i "./input_uvc.so -d /dev/video0 -r 320*240 -f 12" -o " ./output_http.so –p 8090 –w /usr/local/www "

其他用法

$ mjpg_streamer --help
mjpg_streamer --help
-----------------------------------------------------------------------
Usage: mjpg_streamer
  -i | --input "<input-plugin.so> [parameters]"
  -o | --output "<output-plugin.so> [parameters]"
 [-h | --help ]........: display this help
 [-v | --version ].....: display version information
 [-b | --background]...: fork to the background, daemon mode
-----------------------------------------------------------------------
Example #1:
 To open an UVC webcam "/dev/video1" and stream it via HTTP:
  mjpg_streamer -i "input_uvc.so -d /dev/video1" -o "output_http.so"
-----------------------------------------------------------------------
Example #2:
 To open an UVC webcam and stream via HTTP port 8090:
  mjpg_streamer -i "input_uvc.so" -o "output_http.so -p 8090"
-----------------------------------------------------------------------
Example #3:
 To get help for a certain input plugin:
  mjpg_streamer -i "input_uvc.so --help"
-----------------------------------------------------------------------
In case the modules (=plugins) can not be found:
 * Set the default search path for the modules with:
   export LD_LIBRARY_PATH=/path/to/plugins,
 * or put the plugins into the "/lib/" or "/usr/lib" folder,
 * or instead of just providing the plugin file name, use a complete
   path and filename:
   mjpg_streamer -i "/path/to/modules/input_uvc.so"
-----------------------------------------------------------------------

直接命令启动

➜  lib pwd
/usr/local/lib

➜  lib mjpg_streamer -i "input_uvc.so" -o "output_http.so -w /www/mjpg"

然后浏览器访问ip:8080即可看到效果。

创建脚本启动

基本内容如下

#!/bin/bash
PORT="8101"  #启动端口
USER="admin" # 需要修改
PASSWD="admin" # 需要修改
SIZE="320x480" # 320x240也可以
DEVICE="/dev/video0" # 摄像头设备编号
mjpg_streamer -i "/usr/local/lib/input_uvc.so -d $DEVICE -n -y -f 25 -r $SIZE" -o "/usr/local/lib/output_http.so -w /www/mjpg -p $PORT -c $USER:$PASSWD"

直接运行该脚本即可。
