用开源nginx-rtmp-module搭建flash直播环境
1、将nginx和nginx-rtmp-module的源码包解压
PS:nginx-rtmp-module网址
https://github.com/arut/nginx-rtmp-module
2、进入nginx的源代码目录,编译
./configure --add-module=<path-to-nginx-rtmp-module> --without-http_rewrite_module
make
make install
3、写一个测试配置文件
#user nobody;
worker_processes 1;
error_log logs/error.log debug;
#error_log logs/error.log notice;
#error_log logs/error.log info;
#pid logs/nginx.pid;
events {
worker_connections 1024;
}
rtmp {
server {
listen 1935;
chunk_size 4096;
application myapp {
live on;
}
}
}
http {
server {
listen 8080;
location /stat {
rtmp_stat all;
rtmp_stat_stylesheet stat.xsl;
}
location /stat.xsl {
root /home/arut-nginx-rtmp-module-e5d61f2/;
}
location / {
root /home/arut-nginx-rtmp-module-e5d61f2/test/rtmp-publisher;
}
}
}
4、启动nginx
/usr/local/nginx/sbin/nginx -c /home/arut-nginx-rtmp-module-e5d61f2/test/nginx.conf
5、用ffmpeg产生一个模拟直播源,向rtmp服务器推送
ffmpeg -re -i ~/2012.flv -f flv rtmp://192.168.11.75/myapp/test1
注意,源文件必须是H.264+AAC编码的。192.168.11.75是运行nginx的服务器IP
6、访问http://192.168.11.75:8080/stat,可以看到统计情况
7、网页播放测试,用nginx-rtmp-module自带的一个例子修改,在test/rtmp-publisher目录下
player.html
<!DOCTYPE html>
<html>
<head>
<title>RTMP Player</title>
<script type="text/javascript" src="swfobject.js"></script>
<script type="text/javascript">
var flashVars = {
streamer: 'rtmp://192.168.11.75/myapp',
file:'test1'
};
swfobject.embedSWF("RtmpPlayer.swf", "rtmp-publisher", "500", "400", "9.0.0",
null, flashVars);
</script>
</head>
<body>
<div id="rtmp-publisher">
<p>Flash not installed</p>
</div>
</body>
</html>
访问http://192.168.11.75:8080/player.html,可以播放。用三星P7500安卓平台也可以播放,就是
播放大视频会很卡
nginx-rtmp-module还有许多其他特性,例如支持FLV/MP4的点播、HLS直播、多worker工作模式、push and pull工作模式等,以后慢慢挖掘
