git地址

https://github.com/winshining/nginx-http-flv-module/blob/master/README.CN.md

下载nginx-flv模块

git clone https://github.com/arut/nginx-http-flv-module

装nginx依赖

yum -y install openssl openssl-devel

安装nginx

wget http://nginx.org/download/nginx-1.10.3.tar.gz 

tar -zxvf nginx-1.10.3.tar.gz 

cd nginx-1.10.3


//添加rtmp和openssl支持
./configure --add-module=/绝对路径/nginx-http-flv-module --with-http_ssl_module

make && make install

配软链接

ln -s /usr/local/nginx/sbin/nginx /usr/local/bin/

启动nginx

nginx           启动
nginx -s reload 重启
nginx -s stop   停止

配置流媒体

vim /usr/local/nginx/conf/nginx.conf

            chunked_transfer_encoding on; #支持'Transfer-Encoding: chunked'方式回复 
            add_header 'Access-Control-Allow-Origin' '*'; #添加额外的 HTTP 头

重启

nginx -s reload

测试

推流

1.ffmpeg -re -i C:\Users\EDY\Desktop\1.mp4 -vcodec libx264 -acodec aac -f flv rtmp://122.112.245.213:54321/myapp/video_test

ffmpeg -re -i   \
	本地视频路径 \
	 -vcodec libx264 -acodec aac -f flv \
	 rtmp://服务器ip:端口/rtmp的路由匹配/自定义


2. ffmpeg -re -i "video" -c:v copy -c:a aac -b:a 192k -strict -2 -f flv "rtmp"


视频加水印，水印位置默认在右上角
3. ffmpeg -re -i "video" -i "image" -filter_complex overlay=W-w-5:5 -c:v libx264 -c:a aac -b:a 192k -strict -2 -f flv "rtmp"

拉流

http://122.112.245.213/live?port=54321&app=myapp&stream=video_test

live为拉流地址路由匹配,
port等于推流的端口号
app等于推流的路由
stream等于推流后自定义的文件名
