市面上优秀的流媒体服务器解决方案有很多，比如SRS，Red5，EasyDarwin，nginx-rtmp，live555，mediasoup等等。
这些服务器框架各有优缺点，没有一款完美的流媒体服务器解决方案，在流媒体选型的时候，需要根据自己的业务选择适合的流媒体服务器。
nginx-rtmp的部署
RTMP是Real Time Messaging Protocol（实时消息传输协议）的首字母缩写。该协议基于TCP，是一个协议族，包括RTMP基本协议及RTMPT/RTMPS/RTMPE等多种变种。RTMP是一种设计用来进行实时数据通信的网络协议，主要用来在Flash/AIR平台和支持RTMP协议的流媒体/交互服务器之间进行音视频和数据通信。支持该协议的软件包括Adobe Media Server/Ultrant Media Server/red5等。RTMP与HTTP一样，都属于TCP/IP四层模型的应用层。
1.下载nginx 和 nginx-rtmp-module
https://nginx.org/en/download.htmlhttps://github.com/arut/nginx-rtmp-module.git
2.解压压缩包
$tar xvf nginx-1.20.1.tar.gz$unzip nginx-rtmp-module-master.zip
3.创建build目录
$cd nginx-1.20.1$mkdir build
4.config & make & make install
$./configure --prefix=/home/fly/work/nginx-rtmp/nginx-1.20.1/build --add-module=/home/fly/work/nginx-rtmp/nginx-rtmp-module-master$make$make install
5.config过程中错误及错误处理
error : ./configure: error: the HTTP rewrite module requires the PCRE library.error :./configure: error: SSL modules require the OpenSSL library.error :./configure: error: the HTTP gzip module requires the zlib library.
sudo apt-get updatesudo apt-get install libpcre3 libpcre3-devsudo apt-get install openssl libssl-devsudo apt-get install zlib1g-dev
6.配置文件：/home/fly/work/nginx-rtmp/nginx-1.20.1/build/conf/nginx.conf
rtmp {server {listen 1935;chunk_size 4096;# live onapplication rtmp_live {live on;# hls on; #这个参数把直播服务器改造成实时回放服务器。# wait_key on; #对视频切片进行保护，这样就不会产生马赛克了。# hls_path ./sbin/html; #切片视频文件存放位置。# hls_fragment 10s; #每个视频切片的时长。# hls_playlist_length 60s; #总共可以回看的时间，这里设置的是1分钟。# hls_continuous on; #连续模式。# hls_cleanup on; #对多余的切片进行删除。# hls_nested on; #嵌套模式。}# play videosapplication rtmp_play{play ./videos; #build directory}}}
7.启动 nginx
~/home/fly/work/nginx-rtmp/nginx-1.20.1/build$ sudo ./sbin/nginx8.ffmpeg推流
ffmpeg -i test.flv -vcodec libx264 -acodec aac -f flv rtmp://192.168.2.128:1935/rtmp_live/mystream9.VLC拉流（直播、点播）
直播：rtmp://192.168.2.128:1935/rtmp_live/mystream点播：rtmp://192.168.2.128:1935/rtmp_play/test.flv
SRS的部署
1.下载srs源码
https://github.com/ossrs/srs/releases2.解压压缩包
$tar xvf srs-3.0-r8.tar.gz3.创建build目录
$cd srs-3.0-r8/trunk/$mkdir build
4.config & make & make install
$./configure --prefix=/home/fly/work/srs/srs-3.0-r8/trunk/build --full$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
$./configure --prefix=/home/fly/work/srs/srs-3.0-r8/trunk/build --full --without-utest$make$make install
6.增加配置文件：/home/fly/work/srs/srs-3.0-r8/trunk/build/conf/my_hls.conf
listen 1935;max_connections 1000;daemon on;srs_log_tank file;srs_log_level error;srs_log_file ./objs/srs.log;http_server {enabled on;listen 8081;dir ./objs/nginx/html;}vhost __defaultVhost__ {hls {enabled on;hls_fragment 10;hls_window 60;hls_path ./objs/nginx/html;hls_m3u8_file [app]/[stream].m3u8;hls_ts_file [app]/[stream]-[seq].ts;hls_cleanup on;hls_dispose 30;hls_on_error continue;hls_storage disk;hls_wait_keyframe on;hls_acodec aac;hls_vcodec h264;}}
7.启动 srs
~/home/fly/work/srs/srs-3.0-r8/trunk/build$sudo ./objs/srs -c ./conf/my_hls.conf8.ffmpeg推流
ffmpeg -i test.mp4 -vcodec libx264 -acodec aac -f flv rtmp://192.168.2.128:1935/live/index9.生成的 m3u8 和 ts 文件路径
~/work/srs/srs-3.0-r8/trunk/build/objs/nginx/html/live10.VLC拉流（rtmp、http）
rtmp://192.168.2.128:1935/live/indexhttp://192.168.2.128:8081/live/index.m3u8
live555
1.下载live555源码
http://www.live555.com/liveMedia/public/2.解压
