Nginx-rtmp模块实现流媒体play、push、pull功能 推荐

官方wiki:https://github.com/arut/nginx-rtmp-module#readme

Nginx rtmp 功能特点

1. 支持音视频直播2. 支持flv/mp4视频格式，输入可以是文件或者HTTP流3. 支持两种流的分发模式 pushand pull4. 可以将直播流录制成flv文件5. H264/AAC编码6. 支持在线转码 Onlinetranscoding with FFmpeg7. 支持HLS (HTTP LiveStreaming)需要 libavformat (>= 8. 53.31.100) from ffmpeg (ffmpeg.org)8. HTTPcallbacks (publish/play/record/update etc)9. 支持外部程序(exec)10. HTTPcontrol module for recording audio/video and dropping clients11. 先进内存控制技术，可以在使用少量内存的情况下完成流畅的直播功能。12 . 可以和以下协同工作。FMS server（Wirecast, FMS, Wowza,）Player（JWPlayer, FlowPlayer, StrobeMediaPlayback,）外部程序（ffmpeg,avconv,rtmpdump,flvstreamer ）13. Statistics in XML/XSL in machine- & human- readable form14. 支持跨平台 Linux/FreeBSD/MacOS实现环境：

在/etc/init.d/目录下为nginx提供服务器脚本并赋予其执行权限

esac

[root@localhost ~]# chmod +x nginx

添加nginx至服务列表并设置其开机自动启动

[root@localhost ~]# chkconfig --add nginx
[root@localhost ~]# chkconfig nginx on

备份/etc/nginx配置文件，把nginx-rtmp-module-master/test/nginx.conf复制到/etc/nginx目录下

[root@localhost ~]# cd /etc/nginx/
[root@localhost nginx]# mv nginx.conf nginx.conf.bak
[root@localhost ~]# cd nginx-rtmp-module-master/test/
[root@localhost test]# mv nginx.conf /etc/nginx/

修改/etc/nginx/nginx.conf配置文件







172.16.6.39上面的环境与172.16.6.36相同，只不过要在172.16.6.39上实现pull的功能




下载一个.flv结尾的视频文件，使用ffmpeg模拟视频直播源进行测试play、push及pull功能是否实现



使用ffmpeg模拟直播效果，ffmpeg下载链接http://www.ffmpeg.org/download.html
进入ffmpeg-2.2.1-64bit-static目录下，执行如下命令

[root@localhost ffmpeg-2.2.1-64bit-static]# ./ffmpeg -re -i ~/2014.flv -f flv rtmp://172.16.6.36/myapp/test1

然后登录此链接验证能够播放：http://www.wowza.com/resources/3.5.0/examples/LiveVideoStreaming/FlashRTMPPlayer/player.html



验证pull功能是否实现



验证push功能
使用ffmpeg推流的时候，应该推至/mypush中，/mypush有流之后才能push至172.16.6.39的/myapp中，所以执行如下命令

[root@localhost ffmpeg-2.2.1-64bit-static]# ./ffmpeg -re -i ~/2014.flv -f flv rtmp://172.16.6.36/mypush/test1

刚开始学习nginx-rtmp，可能很多地方写的有出入。
