SRS 的部署

本篇文章，我们详细介绍下使用SRS来部署一套流媒体服务器，并用FFmpeg来推流，VLC来拉流。

1.下载srs源码

https://github.com/ossrs/srs/releases

2.解压压缩包

tar xvf srs-server-4.0-b10.tar.gz

3.创建build目录

$cd srs-server-4.0-b10/trunk/

$mkdir build

4.config & make & make install

$./configure --prefix=/opt/srs/srs-server-4.0-b10/trunk/build --full$make$make install

5.make过程中出现错误及解决方法

In file included from ../../../objs/gtest/include/gtest/internal/gtest-port.h:197:0,                 from ../../../objs/gtest/include/gtest/internal/gtest-internal.h:40,                 from ../../../objs/gtest/include/gtest/gtest.h:57,                 from ../../../src/utest/srs_utest.hpp:36,                 
from ../../../src/utest/srs_utest.cpp:24:/usr/include/c++/7/sstream:300:7: error: ‘struct std::__cxx11::basic_stringbuf<_CharT, _Traits, _Alloc>::__xfer_bufptrs’ 
redeclared with different access struct __xfer_bufptrs


$./configure --prefix=/opt/srs/srs-server-4.0-b10/trunk/build --full --without-utest
$make
$make install

6.增加配置文件：/opt/srs/srs-server-4.0-b10/trunk/build/conf/my_hls.conf

listen              1935;
max_connections     1000;
daemon              on;
srs_log_tank        file;
srs_log_level        error;
srs_log_file        ./objs/srs.log;

http_server {
    enabled         on;
    listen          8081;
    dir             ./objs/nginx/html;
}

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;
        hls_cleanup     on;
        hls_dispose     30;
        hls_on_error    continue;
        hls_storage     disk;
        hls_wait_keyframe       on;
        hls_acodec      aac;
        hls_vcodec      h264;
    }
}

7.启动 srs

（1）cd /opt/srs/srs-server-4.0-b10/trunk/build

（2）sudo ./objs/srs -c ./conf/my_hls.conf

（3）./etc/init.d/srs status 查看srs状态

（4）tail -n 30 -f ./objs/srs.log 查看srs日志

8.ffmpeg推流

ffmpeg -stream_loop -1 -v verbose -re -i sample_yuancore_720p.mp4  -f flv rtmp://192.168.41.115:1935/rtmp_live/mystream
 
-stream_loop -1 无限循环推流
-v verbose 详细日志
-re 本来的码率推流
-c:a copy -c:v copy 省略 按照原来编码推流 

9.生成的 m3u8 和 ts 文件路径

/opt/srs/srs-server-4.0-b10/trunk/build/objs/nginx/html/rtmp_live

10.VLC拉流（rtmp、http）

rtmp://192.168.41.115:1935/rtmp_live/mystream
http://192.168.41.115:8081/rtmp_live/index.m3u8
