centos7搭建srs2流媒体服务器,使用flvjs实现摄像头flv流低延时实时直播

此方式只对安卓web播放有效,ios天然不支持,只能使用hls方式,此方式延时可以控制在3秒内

首先访问srs官网
https://github.com/ossrs/srs
下载srs2,

git clone https://github.com/ossrs/srs

推荐中国镜像下载

git clone https://git.oschina.net/winlinvip/srs.oschina.git

更新最新代码

cd ./srs/trunk&&git pull

编译安装

./configure --prefix=/usr/local/srs-flv&&make&&make install

稍等一会~

编辑配置文件

vi ./conf/http.flv.live.conf

写入一下配置,具体可参考官方配置说明

listen              1935;
max_connections     1000;
#daemon              off;
#srs_log_tank        console;
http_server {
    enabled         on;
    listen          8080;
    dir             ./objs/nginx/html;
}
vhost __defaultVhost__ {
#    gop_cache       off;
#    queue_length    10;
#    min_latency     on;
#    mr {
#        enabled     off;
#    }
#    mw_latency      100;
#    tcp_nodelay     on;
    http_remux {
        enabled     on;
        mount       [vhost]/[app]/[stream].flv;
        hstrs       on;
    }
}

之后启动srs for flv

./objs/srs -c ./conf/http.flv.live.conf

后台查看进程是否启动成功

ps -ef|grep srs

执行ffmpeg推流命令

命令options请参考http://www.cuplayer.com/player/PlayerCode/FFmpeg/2018/1114/3329.html

ffmpeg -re  -rtsp_transport tcp -threads 1 -buffer_size 1024000 -max_delay 500000 -i rtsp:admin:@192.168.3.22:554/stream1 -c:v libx264 -b:v 350k -profile:v baseline -level 3.0  -acodec aac  -strict experimental -ar 44100 -ac 2 -b:a 96k  -fflags nobuffer -preset  ultrafast -tune   zerolatency -vcodec h264 -f flv -an rtmp://192.168.153.128:1935/live/192168322

flv地址为访问地址为http://192.168.153.128:1935/live/192168322.flv
