MJPEG-Streamer安装

网上资料大都过期了，还是官网靠谱

安装指南
安装命令-可能会失效，以安装指南为准

# Update & Install Tools
sudo apt-get update
sudo apt-get upgrade -y
sudo apt-get install build-essential libjpeg8-dev imagemagick libv4l-dev cmake -y

# Clone Repo in /tmp
cd /tmp
git clone https://github.com/jacksonliam/mjpg-streamer.git
cd mjpg-streamer/mjpg-streamer-experimental

# Make
make
sudo make install

# Run
/usr/local/bin/mjpg_streamer -i "input_uvc.so -r 1280x720 -d /dev/video0 -f 30 -q 80" -o "output_http.so -p 8080 -w /usr/local/share/mjpg-streamer/www"

访问

http://localhost:8080/stream.html

运行失败

运行失败可能是忘了插摄像头o(╯□╰)o

依赖安装失败

Package libjpeg8-dev is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
However the following packages replace it:

可以加入参数

O(∩_∩)O~其实我重启它自己就好了，机智的自己变格式

增加自启队列

# Make Executable
chmod +x /home/pi/mjpg-streamer.sh

# Open Cron Job
crontab -e

# Add line
@reboot /home/pi/mjpg-streamer.sh start

内网穿透

因为有一台阿里云做跳板，反向代理即可

创建本机秘钥

cd ~/.ssh/
ssh-keygen

公网服务器写入公钥

ssh-copy-id user@server

端口转发

sudo nano sshr.sh

在exit 0 前写入

nohup ssh -NR 0.0.0.0:30522:127.0.0.1:22 username@serverIP > /dev/null 2>&1 &
nohup ssh -NR 0.0.0.0:30580:127.0.0.1:8080 username@serverIP > /dev/null 2>&1 &

22端口用于远程ssh登录

8080端口是默认的MJPEG-Streamer页面访问端口

增加执行权限

sudo chmod +x sshr.sh

增加心跳

nano /etc/ssh/ssh_config

加入

TCPKeepAlive yes
ServerAliveInterval 300
