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

[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
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
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

[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
