MSYS 编译 nginx rtmp-module

1. 下载源码
http://hg.nginx.org/nginx
  nginx-c74904a17021.zip

https://github.com/arut/nginx-rtmp-module
  nginx-rtmp-module-master.zip

https://www.openssl.org/source/
  https://www.openssl.org/source/openssl-1.0.2r.tar.gz

https://ftp.pcre.org/pub/pcre/
  https://ftp.pcre.org/pub/pcre/pcre-8.43.zip

http://www.zlib.net/
  http://www.zlib.net/zlib-1.2.11.tar.gz

2. 源码部署
nginx-rtmp-module-master.zip 解压到 nginx-c74904a17021/nginx-rtmp-module
nginx-c74904a17021 目录下创建目录 libs
openssl-1.0.2r.tar.gz pcre-8.43.zip zlib-1.2.11.tar.gz 解压到 nginx-c74904a17021/libs

3. 启动 MSYS 进入 nginx-c74904a17021 目录
  最新版本 nginx 的 configure 在 auto 目录下
./auto/configure \
--prefix=/usr/opt/nginx-1.15.9 \
--with-pcre=/usr/build/libs/nginx-c74904a17021/libs/pcre-8.43 \
--with-openssl=/usr/build/libs/nginx-c74904a17021/libs/openssl-1.0.2r \
--with-zlib=/usr/build/libs/nginx-c74904a17021/libs/zlib-1.2.11 \
--add-module=/usr/build/libs/nginx-c74904a17021/nginx-rtmp-module \
--with-http_ssl_module 

4. 修改源码
nginx-c74904a17021\nginx-rtmp-module\ngx_rtmp.h
#if (NGX_WIN32)
//typedef __int8              int8_t;
typedef unsigned __int8     uint8_t;
#endif
Note: int8_t 已经在 gcc 里定义过

nginx-c74904a17021\objs\ngx_auto_config.h
#ifndef NGX_PREFIX
//#define NGX_PREFIX  "/usr/opt/nginx-1.15.9/"
#define NGX_PREFIX  "./"
#endif
Note: NGX_PREFIX 定义成 /usr/opt/nginx-1.15.9/ 时 windows 系统无法正确地找到目录

nginx-c74904a17021\objs\Makefile
//CC =	cc
CC =	gcc
Note: MSYS 没有 cc

//advapi32.lib ws2_32.lib /usr/build/libs/nginx-c74904a17021/libs/pcre-8.43/.libs/libpcre.a /usr/build/libs/nginx-c74904a17021/libs/openssl-1.0.2r/.openssl/lib/libssl.a /usr/build/libs/nginx-c74904a17021/libs/openssl-1.0.2r/.openssl/lib/libcrypto.a -lgdi32 -lcrypt32 -lws2_32 /usr/build/libs/nginx-c74904a17021/libs/zlib-1.2.11/libz.a
-l advapi32 -l ws2_32 /usr/build/libs/nginx-c74904a17021/libs/pcre-8.43/.libs/libpcre.a /usr/build/libs/nginx-c74904a17021/libs/openssl-1.0.2r/.openssl/lib/libssl.a /usr/build/libs/nginx-c74904a17021/libs/openssl-1.0.2r/.openssl/lib/libcrypto.a -lgdi32 -lcrypt32 -lws2_32 /usr/build/libs/nginx-c74904a17021/libs/zlib-1.2.11/libz.a
Note: MSYS 不支持 advapi32.lib ws2_32.lib

5. 编译安装
make
make install

opt\nginx-1.15.9\sbin\nginx.exe 移到 opt\nginx-1.15.9\nginx.exe
opt\nginx-1.15.9 目录下创建 nginx-1.15.9\temp\hls

修改 nginx.conf 文件
nginx-1.15.9-v2\conf\nginx.conf

worker_processes  1;
error_log  logs/error.log info;
events {
    worker_connections  1024;
}

rtmp {
    server {
        listen 1935;
        application live {
            live on;
        }
        application hls {
            live on;
            hls on;  
            hls_path temp/hls;  
            hls_fragment 8s;  
        }
    }
}

http {
    server {
        listen      8080;
        location / {
            root html;
        }
		
        location /stat {
            rtmp_stat all;
            rtmp_stat_stylesheet stat.xsl;
        }

        location /stat.xsl {
            root html;
        }
		
        location /hls {  
            #server hls fragments  
            types{  
                application/vnd.apple.mpegurl m3u8;  
                video/mp2t ts;  
            }  
            alias temp/hls;  
            expires -1;  
        }  
    }
}

运行 nginx.exe

6. 测试 
安装 Screen Capturer Recorder v0.12.10
https://sourceforge.net/projects/screencapturer/files/

创建 streaming.cmd
@echo off
set bitrate=1200
set maxrate=2400
set x264=-look_ahead 0 -ac 2 -c:v h264_qsv -profile:v high -level 3.1 -preset:v veryfast
set ki=-keyint_min 72 -g 72 -sc_threshold 0
set br=-b:v %bitrate%k -minrate %bitrate%k -maxrate %maxrate%k -bufsize %maxrate%k -b:a 128k
set vf=-vf crop=854:480:1920-854:0,fps=fps=24
set deskdev=-f dshow -i video="screen-capture-recorder" -f dshow -i audio="virtual-audio-capturer"

ffmpeg -threads 4 -hide_banner -rtbufsize 512M -re %deskdev% %ki% %vf%  %x264% %br% -f flv rtmp://localhost:1935/live/ 

pause

创建 pull.cmd
@echo off
ffplay.exe rtmp://localhost:1935/live/

执行 streaming.cmd 后 执行 pull.cmd
如果能正常播放说明成功了
