基于Nginx+nginx-rtmp-module+ffmpeg搭建rtmp、hls流媒体服务器

上篇文章是基于Red5与ffmpeg实现rtmp处理NVR或摄像头的监控视频处理方案,有兴趣的朋友可以查看。

Nginx及nginx-rtmp-module安装

新建目录
mkdir /usr/local/mginx
下载
cd /usr/local/nginx
wget http://nginx.org/download/nginx-1.12.2.tar.gz
wget https://codeload.github.com/arut/nginx-rtmp-module/zip/master
解压
tar -zxvf nginx-1.12.2.tar.gz
unzip nginx-rtmp-module-master.zip 
安装

nginx的一些模块依赖一些lib库,在安装nginx之前,须先安装这些lib库,

依赖库主要有g++、gcc、openssl-devel、pcre-devel和zlib-devel 视情况执行如下命令安装

yum install gcc-c++ 
yum install pcre pcre-devel  
yum install zlib zlib-devel 
yum install openssl openssl--devel 
nginx-rtmp-module模块安装
cd /usr/local/nginx/nginx-1.12.2
#完成rtmp模块安装
./configure --add-module=/usr/local/nginx/nginx-rtmp-module-master
make
make install

至此nginx及相关模块安装完毕

配置及启动服务支持rtmp

http服务测试 http://127.0.0.1/


利用ffmpeg进行推流直播

ffmpeg -re -i "E:\ffmpeg-20180227-fa0c9d6-win64-static\bin\1234.mp4" -acodec copy -vcodec copy -f flv -an  rtmp://192.168.174.200:1935/live/a 

利用vlc测试,地址:rtmp://192.168.174.200:1935/live/a


点播

将本地mp4文件复制到/usr/local/nginx/html/hls

利用vlc测试:rtmp://192.168.174.200:1935/vod/1234.mp4

配置支持hls

工作流程
点播:准备好视频文件MP4,使用ffmpeg将其转成TS格式文件,然后继续使用ffmpeg将其切片并生成播放列表M3U8文件,将所得TS分片与M3U8文件放到nginx服务器目录下,开启http服务器后,同一局域网内用手机输入网络地址可查看点播视频。 
直播:使用VLC软件将视频以rtsp流的形式发出,使用ffmpeg接收这个rtsp流并实时切割到http服务器下,开启服务器后,同一局域网内用手机输入网络地址可查看直播视频。
修改配置文件
cd /usr/local/nginx/conf
vim mime.types

#在 application/zip zip; 这一行后面增加2行: 
application/x-mpegURL m3u8; 
application/vnd.apple.mpegurl m3u8;

vim video/x-msvideo
#avi;行后,增加1行:
video/MP2T ts;
点播

使用ffmpeg将mp4格式文件转成TS格式文件

ffmpeg -y -i 1234.mp4 -vcodec copy -acodec copy -vbsf h264_mp4toannexb test.ts

使用ffmpeg将TS文件切成ts分片并产生m3u8文件

ffmpeg -i test.ts -c copy -map 0 -f segment -segment_list playlist.m3u8 -segment_time 2 test%03d.ts

将所得的ts分片和m3u8文件放到nginx\html目录下

vlc输入[ http://192.168.174.200:80/playlist.m3u8 ]即可看到点播视频 

注:192.168.174.200是本机的局域网ip,也即http服务器的ip

直播
将视频以rtsp流的形式从vlc上发出来(具体方法请自查) 

使用ffmpeg接收rtsp流并自动实时切片到http服务器下

ffmpeg -i rtsp://admin:[email protected]/cam/realmonitor?channel=1&subtype=1 -c copy -vcodec h264 -f hls -hls_time 2.0 -hls_list_size 5 -hls_wrap 5 /usr/local/nginx/html/test.m3u8

vlc输入[ http://172.19.12.240/test.m3u8 ]即可看到直播视频

录制

通过ffmpeg向服务器推流,在服务器进行视频录制

ffmpeg -re -i "E:\ffmpeg-20180227-fa0c9d6-win64-static\bin\1234.mp4" -acodec copy -vcodec copy -f flv -an  rtmp://192.168.174.200:1935/live/a
http://192.168.174.200/hls/a/index.m3u8

修改nginx.conf配置

rtmp {
    server {
	listen 1935;
	chunk_size 4096;

	application vod {
		play /usr/local/nginx/html/hls;
     	}

    	application live {
                live on;
	        hls on; #这个参数把直播服务器改造成实时回放服务器。
                wait_key on; #对视频切片进行保护,这样就不会产生马赛克了。
                hls_path /usr/local/nginx/html/hls; #切片视频文件存放位置。
                hls_fragment 10s;     #每个视频切片的时长。
                hls_playlist_length 60s;  #总共可以回看的事件,这里设置的是1分钟。
                hls_continuous on; #连续模式。
                hls_cleanup on;    #对多余的切片进行删除。
                hls_nested on;     #嵌套模式。
        }
    }
}

查看已经产生切片视频文件了。其中还有一个index.m3u8。 

cd /usr/local/nginx/html/hls/a/
ls

vlc输入[ http://192.168.174.200/hls/a/index.m3u8 ]即可看到视频
