用开源nginx-rtmp-module搭建flash直播环境

2012-10-16 12:05:00| 分类： ffmpeg|字号订阅

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

8、HLS测试（2013-4-20更新）

修改测试的配置文件

rtmp

...

        application myapp {
            live on;
            hls on;
            hls_path /tmp/app;
            hls_fragment 5s;
        }
...

http

...

        location /hls {
            # Serve HLS fragments
            types {
                application/vnd.apple.mpegurl m3u8;
            }
            alias /tmp/app;
            expires -1;
        }

配套的测试html文件

<!DOCTYPE html>
<html>
<head>
<title>HLS Player</title>
</head>
<body>
<video height="270" width="480" controls>
<source src="http://211.154.154.80:8080/hls/test1.m3u8" type="application/vnd.apple.mpegurl" />
<p class="warning">Your browser does not support HTML5 video.</p>
</video>
</body>
</html>

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
