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 pull
4. 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 FFmpeg
7. 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 clients
11. 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 form
14. 支持跨平台 Linux/FreeBSD/MacOS

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