本文概要:
nginx是非常優秀的開源伺服器,用它來做hls或者rtmp流媒體伺服器是非常不錯的選擇。本文介紹了一種簡易方法快速搭建rtmp流媒體伺服器,也叫rtsp轉播,資料源不是讀取檔案,而是采用擷取rtspNal流後使用ffmpeg轉播。csdn固本培元:[email protected]
開發環境:centos6.4 (主流的linux伺服器選擇,30%以上的市場占有率)
需要這幾個包。
版本号:nginx 1.7.3 openssl 1.0.2 rtmp-module(版本未知)
資源:這些都是公網下載下傳的資源,有需要的朋友,可以給我email或者評論留言。email:[email protected]
注意:先編譯openssl 然後編譯nginx
編譯選項:
./configure –add-module=../nginx-rtmp-module-master –without-http_rewrite_module –with-openssl=../openssl-1.0.2-beta2
一路通過
啟動時可能出現錯誤:
Starting nginx: nginx: [emerg] unknown directive “rtmp” in /etc/nginx/nginx.conf:9
沒有識别rtmp子產品。
另外一種可能,原有centos從源安裝了nginx,它不帶rtmp子產品,需要解除安裝。
安裝編譯好的nginx後:
進入:
/usr/local/nginx/sbin
./nginx -c /usr/local/nginx/conf/nginx.conf
(注意:後面的需要是絕對位址)
ffmpeg推流 (如果沒有flv檔案,可以用264,ts這些檔案轉換,ffmpeg的常用指令本部落格另一篇文章也有簡要介紹)
ffmpeg -re -i IpCam.flv -f flv rtmp://localhost/myapp/test1
ffmpeg -re -i IpCam.flv -f flv -b 20000000 rtmp://localhost/myapp/test1
實時rtsp轉rtmp直播流(其實轉了rtmp之後會多幾秒鐘的延遲,不同用戶端還不一定一緻,我們這裡測試的是JWplayer 3秒左右(後面用了個flex的方案,時間延遲提升到2s),穩定時可以在1秒左右,vlc播放器更長了10秒 ~_~! ,用戶端的話還是就用rtsp吧,這樣很快,一般延遲可以忽略不計,rtmp本來就是為web端設計的)
rtsp流的擷取方法可以參考另外一篇文章:http://blog.csdn.net/gubenpeiyuan/article/details/19072223
ffmpeg -re -i RealStream.fifo -f flv -b 20000000 rtmp://localhost/myapp/test1
RealStream.fifo 是建立的fifo。 指令: mkfifo RealStream.fifo
啟動rtsp擷取Nal添加sps和pps位,之後打開fifo實時寫入即可。
使用vlc測試如下:

此後可以将實時流推送到rmp了。
我的方案是live555接收流,串流方式推送至fifo,做rtmp的轉發。可能有些延遲,哪位朋友有更好的方案,歡迎交流評論。
其架構如下:非常簡單,并容易內建入大流媒體架構。
