nginx、nginx-rtmp-module模塊實現流媒體play、push、pull功能

原帖地址:http://blog.51cto.com/lyd0721/1429803html

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

Nginx rtmp 功能特色

1.   支持音視頻直播git

2.   支持flv/mp4視頻格式,輸入能夠是文件或者HTTP流github

3.   支持兩種流的分發模式 pushand pullbash

4.   能夠將直播流錄製成flv文件服務器

5.   H264/AAC編碼網絡

6.   支持在線轉碼 Onlinetranscoding with FFmpegapp

7.   支持HLS (HTTP LiveStreaming)須要 libavformat (>= 8. 53.31.100) from ffmpeg (ffmpeg.org)tcp

8.   HTTPcallbacks (publish/play/record/update etc)ide

9.   支持外部程序(exec)

10.  HTTPcontrol module for recording audio/video and dropping clients

11.  先進內存控制技術,能夠在使用少許內存的狀況下完成流暢的直播功能。

12 . 能夠和如下協同工做。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 form

14.  支持跨平臺 Linux/FreeBSD/MacOS

實現環境:

 

rhel6.1 172.16.6.36
rhel6.1 172.16.6.39

編譯環境:安裝gcc、openssl-devel、pcre-devel

網絡yum源配置參考連接:http://lyd0721.blog.51cto.com/4894702/1428467

下載並解壓nginx-rtmp-module模塊

編譯安裝nginx

./configure \
--prefix=/usr/local/nginx \
--with-openssl=/usr/local/openssl \
--with-pcre \
--with-http_ssl_module \
--with-http_v2_module \                                     
--with-http_gunzip_module \
--with-http_gzip_static_module \
--with-http_perl_module \
--with-stream \
--with-http_flv_module \
--with-http_mp4_module \
--add-module=../nginx-rtmp-module \
--add-module=../nginx_tcp_proxy_module

 

在/etc/init.d/目錄下爲nginx提供服務器腳本並賦予其執行權限

esac

 

[root@localhost ~]# chmod +x nginx

 

添加nginx至服務列表並設置其開機自動啓動

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

 

備份/etc/nginx配置文件,把nginx-rtmp-module-master/test/nginx.conf複製到/etc/nginx目錄下

[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上面的環境與172.16.6.36相同,只不過要在172.16.6.39上實現pull的功能

 

下載一個.flv結尾的視頻文件,使用ffmpeg模擬視頻直播源進行測試play、push及pull功能是否實現

wKioL1Onxu3T8Nh2AACcSeSL_cU743.jpg

使用ffmpeg模擬直播效果,ffmpeg下載連接http://www.ffmpeg.org/download.html

進入ffmpeg-2.2.1-64bit-static目錄下,執行以下命令

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

 

而後登陸此連接驗證可以播放:http://www.wowza.com/resources/3.5.0/examples/LiveVideoStreaming/FlashRTMPPlayer/player.html

驗證pull功能是否實現

wKioL1OnyKmDVW1xAAEq0cnx9ro718.jpg

驗證push功能

使用ffmpeg推流的時候,應該推至/mypush中,/mypush有流以後才能push至172.16.6.39的/myapp中,因此執行以下命令

1
[root@localhost ffmpeg-2.2.1-64bit-static] # ./ffmpeg -re -i ~/2014.flv -f flv rtmp://172.16.6.36/mypush/test1

剛開始學習nginx-rtmp,可能不少地方寫的有出入
