使用开源的SRS 搭建一个直播服务

环境

操作系统：centos 7

推流软件：obs 或 ffmpeg

拉流软件：ffplay 或 vlc

安装

如果是 centos 6 可以直接下载这个进行安装

# wget -c http://ossrs.net/srs.release/releases/files/SRS-CentOS6-x86_64-2.0.239.zip

# unzip SRS-CentOS6-x86_64-2.0.239.zip
# cd SRS-CentOS6-x86_64-2.0.239
# chmod +x INSTALL
# ./INSTALL

安装在/usr/local/srs目录中，可以直接使用

/etc/init.d/srs start

启动

centos 7 需要编译

[root@adsl-172-10-100-120 opt]# wget -c https://github.com/ossrs/srs/archive/v2.0-r1.tar.gz
[root@adsl-172-10-100-120 opt]# tar zxvf v2.0-r1.tar.gz
[root@adsl-172-10-100-120 opt]# cd srs-2.0-r1/

然后进入到 trunk 目录

[root@adsl-172-10-100-120 srs-2.0-r1]# cd trunk/
[root@adsl-172-10-100-120 trunk]# ls
3rdparty  auto  conf  configure  doc  etc  ide  modules  research  scripts  src

使用 help 可以查看编译帮助文档

[root@adsl-172-10-100-120 trunk]# ./configure --help

比如我这里编译全部的模块安装到 /usr/local/srs 目录

[root@adsl-172-10-100-120 trunk]# ./configure --full --prefix=/usr/local/srs

然后

make && make install

进入 /usr/local/srs

[root@adsl-172-10-100-120 srs]# pwd
/usr/local/srs
[root@adsl-172-10-100-120 srs]# ./objs/
nginx/ srs
[root@adsl-172-10-100-120 srs]# ./objs/srs -c ./conf/srs.conf

##推流

➜  Downloads ffmpeg -i gopro.mp4 -vcodec libx264 -acodec aac -f flv rtmp://172.10.100.120/live/lol

拉流

然后 ffplay 播放

默认的配置文件是 srs.conf

[root@adsl-172-10-100-120 conf]# cat srs.conf
# main config for srs.
# @see full.conf for detail config.

listen              1935;
max_connections     1000;
srs_log_tank        file;
srs_log_file        ./objs/srs.log;
http_api {
    enabled         on;
    listen          1985; #默认端口1985
}
http_server {
    enabled         on;
    listen          8080;
    dir             ./objs/nginx/html;
}
stats {
    network         0;
    disk            sda sdb xvda xvdb;
}
vhost __defaultVhost__ { #虚拟主机
}

如果你希望将推流的内容转换成 hls，可以参考

[root@adsl-172-10-100-120 conf]# cat hls.conf
# the config for srs to delivery hls
# @see https://github.com/ossrs/srs/wiki/v1_CN_SampleHLS
# @see full.conf for detail config.

listen              1935;
max_connections     1000;
daemon              off;
srs_log_tank        console;
vhost __defaultVhost__ {
    hls {
        enabled         on;
        hls_fragment    10;
        hls_window      60;
        hls_path        ./objs/nginx/html;
        hls_m3u8_file   [app]/[stream].m3u8;
        hls_ts_file     [app]/[stream]-[seq].ts;
    }
}
