nodejs stream-server.js huang 监听随机端口
Listening for MPEG Stream on http://127.0.0.1:8082/<secret>/<width>/<height>
Awaiting WebSocket connections on ws://127.0.0.1:8084/

a、关掉防火墙，至少将视频流端口开启
b、vlc --ttl 12 -vvv --color -I telnet --telnet-password videolan --rtsp-host 0.0.0.0 --rtsp-port 5554
c、通过telnet启动vlc的vlm管理中，telnet 127.0.0.1 4212，密码是刚才的videolan
d、new Test vod enabled 新建一个vod，名字是Test
e、setup Test input /path/video.file 给Test输入视频
f、vlc rtsp://127.0.0.1:5554/Test 启动vlc观看视频流，这里还差声音

a、安装openresty和rtmp模块
b、配置nginx，rtmp配置块与http配置块平级
rtmp {
server {
listen 1935;
application live1 {
live on;
record off;
}
}
}
c、ffmpeg转发视频流
ffmpeg -re -i xxx.mp4 -c copy -f flv rtmp://localhost:1935/live1/room1
其中的live1是应用，room1是将来要打开的节点
d、在vlc中打开视频流：
rtmp://localhost:1935/live1/room1
e、ffmpeg -f video4linux2 -i /dev/video0 -c:v libx264 -an -f flv rtmp://localhost:1935/live1/room1 试试摄像头

aliyun+nginx+rtmp在线转播
site: http://blog.csdn.net/xdwyyan/article/details/43198985
注意：在nginx中配置rtmp后，reload是不够的，需要kill掉重新启动nginx。
通过sudo netstat -tlnp | grep 1935来观察nginx是否将端口打开

#v4l2读取摄像头，进行x264编码并将视频流发送至阿里云，进而进行hls播放
ffmpeg -f video4linux2 -s 320x240 -i /dev/video0 -vcodec libx264 -f flv rtmp://101.200.124.174:1935/hls/movie

防火墙设置，配置1985端口可以被外网访问
huang@vultr:~$ sudo iptables -A INPUT -m state --state NEW -m tcp -p tcp --dport 1985 -j ACCEPT
