檢視 CentOS:RTMP流媒体服务器的原始碼

=编译安装nginx=
利用nginx搭建rtmp流媒体服务器。首先安装编译工具链：
<source lang="bash">
yum groupinstall "Development Tools"
</source>
安装完成后，下载源码到同一目录并解压：
<source lang="bash">
wget http://nginx.org/download/nginx-1.10.1.tar.gz
wget http://h264.code-shop.com/download/nginx_mod_h264_streaming-2.2.7.tar.gz
wget http://sourceforge.net/projects/pcre/files/pcre/8.39/pcre-8.39.tar.gz
wget http://zlib.net/zlib-1.2.8.tar.gz
wget https://www.openssl.org/source/openssl-1.1.0.tar.gz
wget https://github.com/arut/nginx-rtmp-module/archive/v1.1.9.tar.gz

tar -zxvf nginx-1.10.1.tar.gz 
tar -zxvf nginx_mod_h264_streaming-2.2.7.tar.gz 
tar -zxvf pcre-8.39.tar.gz 
tar -zxvf zlib-1.2.8.tar.gz 
tar -zxvf openssl-1.1.0.tar.gz 
tar -zxvf v1.1.9.tar.gz 
</source>
解压完成后，cd到nginx源码目录，
<source lang="bash">
./configure \
--prefix=/usr/local/nginx \
--add-module=../nginx_mod_h264_streaming-2.2.7 \
--add-module=../nginx-rtmp-module-1.1.9 \
--with-http_flv_module \
--with-http_mp4_module \
--with-http_stub_status_module \
--with-http_ssl_module \
--with-pcre=../pcre-8.39 \
--with-zlib=../zlib-1.2.8 \
--with-openssl=../openssl-1.0.2h \
--with-debug
</source>
配置完成后，结果如下：
<pre>

</pre>
=编译错误解决=
开始编译：
<source lang="bash">
make && make install
</source>
可能出现这个错误：
<pre>
		../nginx_mod_h264_streaming-2.2.7/src/ngx_http_h264_streaming_module.c
In file included from ../nginx_mod_h264_streaming-2.2.7/src/ngx_http_h264_streaming_module.c:2:
../nginx_mod_h264_streaming-2.2.7/src/ngx_http_streaming_module.c: In function 'ngx_streaming_handler':
../nginx_mod_h264_streaming-2.2.7/src/ngx_http_streaming_module.c:158: error: 'ngx_http_request_t' has no 
member named 'zero_in_uri'
make[1]: *** [objs/addon/src/ngx_http_h264_streaming_module.o] Error 1
make[1]: Leaving directory `/home/rtmp/nginx-1.10.1'
make: *** [build] Error 2
</pre>
解决办法：注释掉如下的函数：
<source lang="bash">
vim ../nginx_mod_h264_streaming-2.2.7/src/ngx_http_streaming_module.c

/* TODO: Win32 */
/*
if (r->zero_in_uri)
{
     return NGX_DECLINED;
}
*/
</source>
编译完后后，输出如下:
<pre>
sed -e "s|%%PREFIX%%|/usr/local/nginx|" \
		-e "s|%%PID_PATH%%|/usr/local/nginx/logs/nginx.pid|" \
		-e "s|%%CONF_PATH%%|/usr/local/nginx/conf/nginx.conf|" \
		-e "s|%%ERROR_LOG_PATH%%|/usr/local/nginx/logs/error.log|" \
		< man/nginx.8 > objs/nginx.8
make[1]: Leaving directory `/home/rtmp/nginx-1.10.1'
</pre>

=配置nginx=
增加如下内容到nginx配置文件usr/local/nginx/conf/nginx.conf：
<source lang="lua">
rtmp{
	server{
		listen 1935;
		chunk_size 4000;
		application live{
			live on;
			meta copy;
		}
	}
}
</source>
*启动  ./nginx
*优雅关闭   ./nginx -s quit
*快速关闭   ./nginx -s stop
