基于NGINX的HLS直播服务搭建

nginx配合ffmpeg做流媒体服务器的原理是:nginx通过rtmp模块提供rtmp服务, ffmpeg推送一个rtmp流到nginx, 然后客户端通过访问nginx来收看实时视频流. HLS也是差不多的原理,只是rtmp是直接推送到nginx,hls是通过暂存ts切片推送,类似点播的直播,最终客户端是通过HTTP协议来访问的,但是ffmpeg推送流仍然是rtmp的.
为了使能尽可能多的功能，重新编译nginx和ffmpeg，下面是编译成功的nginx编译选项，这一步不是必须的，可以通过apt-get或yum安装

1、nginx-1.8.1.tar.gz源码 http://nginx.org/download/nginx-1.8.1.tar.gz
2、nginx_mod_h264_streaming-2.2.7.tar.gz
http://h264.code-shop.com/download/nginx_mod_h264_streaming-2.2.7.tar.gz
3、nginx-rtmp-module.zip
https://codeload.github.com/arut/nginx-rtmp-module/zip/master
4、openssl-0.9.8e.tar.gz
https://www.openssl.org/source/old/0.9.x/openssl-0.9.8e.tar.gz
解压nginx-1.8.1.tar.gz
5、ffmpeg-3.2.4.tar.bz2
http://ffmpeg.org/releases/ffmpeg-3.2.4.tar.bz2
cd nginx-1.8.1

修改/etc/nginx/nginx.conf使能rtmp和hls支持直播和点播，其中8080为直播端口，1935为推送端口

hls推送测试 ffmpeg -re -i sample.flv -vcodec copy -acodec copy -f flv rtmp://server-ip-address/hls/livehls
监控测试ffmpeg -f dshow -i video=“USB2.0 Camera” -vcodec libx264 -pix_fmt yuv420p -f flv rtmp://server-ip-address/hls/livehls

在/var/www/html创建播放索引文件playhls.html：

用支持hls的浏览器打开http://server-ip-address:8080
就可以观看直播，如果不行，测试http://server-ip-address:8080/hls/livehls.m3u8
