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,有兴趣的朋友能够查看。php
mkdir /usr/local/mginx
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
tar -zxvf nginx-1.12.2.tar.gz unzip nginx-rtmp-module-master.zip
nginx的一些模块依赖一些lib库,在安装nginx以前,须先安装这些lib库,
html
依赖库主要有g++、gcc、openssl-devel、pcre-devel和zlib-devel 视状况执行以下命令安装nginx
yum install gcc-c++ yum install pcre pcre-devel yum install zlib zlib-devel yum install openssl openssl--develnginx-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c++
cd /usr/local/nginx/conf vim nginx.conf

cd /usr/local/nginx/sbin nginx #启动服务 nginx -s stop #管理服务

利用ffmpeg进行推流直播github
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/avim
将本地mp4文件复制到/usr/local/nginx/html/hls服务器
利用vlc测试:rtmp://192.168.174.200:1935/vod/1234.mp4网络
cd /usr/local/nginx/conf vim mime.types #在 application/zip zip; 这一行后面增长2行: application/x-mpegURL m3u8; application/vnd.apple.mpegurl m3u8; vim video/x-msvideo #avi;行后,增长1行: video/MP2T ts;
使用ffmpeg将mp4格式文件转成TS格式文件
session
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 ]便可看到点播视频
注:192.168.174.200是本机的局域网ip,也即http服务器的ip
使用ffmpeg接收rtsp流并自动实时切片到http服务器下
ffmpeg -i rtsp://admin:admin@172.19.12.192/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 ]便可看到直播视频
经过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形成实时回放服务器。 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; #每一个视频切片的时长。 hls_playlist_length 60s; #总共能够回看的事件,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 ]便可看到视频
