nginx-rtmp配置

环境

系统环境：Centos 7

需求

centos7编译安装nginx nginx-rtmp

准备

安装依赖：

yum install -y git gcc gcc-c++ autoconf automake zlib zlib-devel openssl openssl-devel pcre pcre-devel

下载安装包：

#download nginx
wget -c http://nginx.org/download/nginx-1.8.1.tar.gz

#download pcre
wget -c https://sourceforge.net/projects/pcre/files/pcre/8.35/pcre-8.35.tar.gz

#download zlib
wget -c http://zlib.net/zlib-1.2.8.tar.gz

#download openssl
wget -c http://www.openssl.org/source/openssl-1.0.1i.tar.gz

注意：这里的依赖包不需要编译版的，需要指定未编译的路径
注意：这里的依赖包不需要编译版的，需要指定未编译的路径（好像编译nginx的时候其他依赖都是需要未编译的）

添加用户

groupadd -r nginx

useradd -r -g nginx

下载nginx-rtmp-module

git clone https://github.com/arut/nginx-rtmp-module.git
#编译的时候添加nginx-rtmp-module模块不需要则不添加
--add-module=path_of_/nginx-rtmp-module

编译安装nginx

./configure \
--prefix=/opt/nginx \#nginx安装路径
--user=nginx \#添加用户
--group=nginx \#添加用户组
--with-http_ssl_module \
--with-http_gzip_static_module \
--with-http_stub_status_module \
--with-http_realip_module \
--pid-path=/var/run/nginx.pid \#pid路径
--with-pcre=/opt/software/pcre-8.35 \  #依赖pcre的源码路径
--with-zlib=/opt/software/zlib-1.2.8 \  #依赖zlib的源码路径
--with-openssl=/opt/software/openssl-1.0.1i  #依赖openssl的源码路径

--add-module=/opt/software/nginx-rtmp-module    #添加nginx-rtmp-module模块（要弄rtmp服务器必须加上这条）

make

make install

修改nginx.conf配置

重启ngixn

nginx -t #测试nginx配置是否有错
nginx -s reload #重新加载nginx配置

使用ffmpeg推流到nginx

• 推一个本地的mp4到上面配置的myapp上（rtmp）：

ffmpeg -re -i /tmp/ffmpeg_test.mp4 -vcodec copy -acodec copy -f flv "rtmp://127.0.0.1:1935/myapp/test1"

rtmp://115.29.123.32:1935/myapp/test1 (115.29.123.32是该服务器ip，我是配合vlc拉流测试的)

• 推一个本地的mp4到hls上

ffmpeg -re -i /tmp/ffmpeg_test.mp4 -vcodec copy -acodec copy -f flv "rtmp://127.0.0.1:1935/hls/test2"

流播放地址为： http://10.0.0.6/hls/test2.m3u8（这里没有端口号）

FFmpeg合并视频

ffmpeg -i input1.flv -c copy -bsf:v h264_mp4toannexb -f mpegts input1.ts
ffmpeg -i input2.flv -c copy -bsf:v h264_mp4toannexb -f mpegts input2.ts
ffmpeg -i input3.flv -c copy -bsf:v h264_mp4toannexb -f mpegts input3.ts

ffmpeg -i "concat:input1.ts|input2.ts|input3.ts" -c copy -bsf:a aac_adtstoasc -movflags +faststart output.mp4

如果上面个合并命令不成功
ffmpeg -i "concat:input1.ts|input2.ts|input3.ts" -c copy -bsf:a aac_adtstoasc  output.mp4（去掉 -movflags +faststart）

FFmpeg的安装方法请参考文章：http://blog.csdn.net/loyachen/article/details/50909854
可能有的文件下载有些慢 可以下载好再上传上去
