nginx的RTMP协议服务器
by ahuner
通过以下的配置，可以使nginx接收RTMP流，并在web上播放实时视频。
1.openssl安装
nginx需要http_ssl_module模块，需要openssl库。
下载opensll:http://www.openssl.org/
最新稳定版本:openssl-1.0.1e
修改三个文件的代码，openssl-1.0.1e\test中的md2test.c、rc5test.c、jpaketest.c
将dummytest.c修改为#include "dummytest.c"。
编译：
chmod +x config
编译静态库
./config --prefix=/usr/local --openssldir=/usr/local/opensll
make && make install
编译动态库
./config shared --prefix=/usr/local --openssldir=/usr/local/opensll
make clean
make && make install
2.nginx的rtmp模块
下载nginx-rtmp-module
https://github.com/arut/nginx-rtmp-module
3.nginx安装
./configure \
--prefix=/usr/local/nginx \
--sbin-path=/usr/local/nginx/nginx \
--conf-path=/usr/local/nginx/nginx.conf \
--pid-path=/usr/local/nginx/nginx.pid \
--error-log-path=/usr/local/nginx/logs/error.log \
--with-pcre=../pcre-8.31 \
--with-zlib=../zlib-1.2.7 \
--with-http_dav_module \
--with-http_flv_module \
--with-http_stub_status_module \
--without-http_scgi_module \
--without-http_uwsgi_module \
--without-http_gzip_module \
--without-http_ssi_module \
--without-http_proxy_module \
--without-http_memcached_module \
--without-http_empty_gif_module \
--without-mail_pop3_module \
--without-mail_imap_module \
--without-mail_smtp_module \
--with-http_ssl_module \
--with-openssl=/project/openssl-1.0.1e \
--add-module=/project/nginx-rtmp-module-master
注意：/project/openssl-1.0.1e为openssl的源代码目录，编译nginx的时候会自动编译连接openssl.
make && make install
4.nginx.conf
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 80;
location /stat {
rtmp_stat all;
rtmp_stat_stylesheet stat.xsl;
}
location /stat.xsl {
root /project/nginx-rtmp-module-master/;
}
location / {
root /project/nginx-rtmp-module-master/test/rtmp-publisher;
}
}
}
5.推流
"rtmp://192.168.1.102/myapp"表示url， "test1"表示stream
推流方式1：ffmpeg -re -i ~/2012.flv -f flv rtmp://192.168.1.102/myapp/test1
推流方式2：Adobe Flash Media Live Encoder设置上述参数
6.直播播放
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://192.168.1.102/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>
