Linux-Nginx+rtmp+ffmpeg搭建流媒体服务器

Nginx+rtmp+ffmpeg搭建流媒体服务器

说明:

  nginx搭建流媒体服务需要用到 nginx-rtmp-module 模块

具体操作步骤:

安装nginx

(1)下载第三方扩展模块nginx-rtmp-module

# mkdir module && cd module          //创建一个存放模块的目录
# wget https://github.com/arut/nginx-rtmp-module/archive/master.zip //下载模块
# unzip master.zip         //解压
# ls nginx-rtmp-module-master/ //查看模块目录

(2)编译安装nginx说明:此处由于我这边已有lnmp运行项目的环境,直接动态添加的 nginx-rtmp-module模块; 动态参加可参考这里

# yum -y install pcre-devel openssl openssl-devel        //安装依赖
# wget http://nginx.org/download/nginx-1.12.2.tar.gz //下载nginx包
# tar xf nginx-1.12..tar.gz
# ./configure --prefix=/opt/nginx-1.9. --add-module=/root/module/nginx-rtmp-module-master --with-http_ssl_module //编译安装nginx,并指定上面下载的模块路径
# make
# make install

(3)修改nginx配置文件,添加如下内容并重新载入配置文件

# vim nginx.conf
rtmp {
server {
listen ; #监听的端口号
application myapp { #自定义的名字
live on;
}
application hls {
live on;
hls on;
hls_path /tmp/hls;
hls_fragment 1s;
hls_playlist_length 3s;
}
}
}
# /etc/init.d/nginx reload
user  root;
worker_processes ;
worker_cpu_affinity ;
worker_rlimit_nofile ; #error_log logs/error.log warn;
pid /var/run/nginx.pid; events {
worker_connections ;
use epoll;
} rtmp {
server {
listen ;
application myapp {
live on;
}
application hls {
live on;
hls on;
hls_path /tmp/rtmp/hls;
hls_fragment 1s;
hls_playlist_length 3s;
}
}
} http { limit_req_zone $binary_remote_addr zone=req_one:10m rate=1r/s; autoindex off;
include /opt/nginx-1.9./conf/mime.types;
default_type application/octet-stream; log_format main '$remote_addr [$time_local] "$request" '
'$status $body_bytes_sent "$http_referer" '
'"$http_user_agent" $http_x_forwarded_for $request_length $request_time "$upstream_response_time" "$upstream_addr" $host $server_addr'; #access_log logs/access.log main;
server_tokens off;
sendfile on;
#tcp_nopush on; keepalive_timeout ; gzip on;
gzip_min_length 1K;
gzip_buffers 16K;
gzip_comp_level ;
gzip_http_version 1.0;
gzip_types application/json text/javascript text/plain application/x-javascript text/css application/xml text/xml;
#gzip_types application/json text/javascript text/plain application/x-javascript text/css application/xml text/xml image/jpeg image/gif image/png;
gzip_disable "MSIE [1-6]\.";
client_max_body_size 500M; #server {
# listen default;
# return ;
#} include /opt/nginx-1.9./conf/conf.d/*.conf; }

完整nginx.conf

安装ffmpeg

ffmpeg命令参考这位朋友的文章:https://www.jianshu.com/p/049d03705a81

(1)安装依赖

# yum install yasm -y

(2)下载ffmpeg并安装

# git clone https://git.ffmpeg.org/ffmpeg.git ffmpeg    //下载ffmpeg
# cd ffmpeg
# ./configure --prefix=/usr/local/ffmpeg
# make
# make install

(3)拷贝命令到/usr/bin(方便后面调用)

# ls /usr/local/ffmpeg/        //查看安装目录生成的文件
bin include lib share
# cp /usr/local/ffmpeg/bin/* /usr/bin/

测试

(1)启用ffmpeg进行推流

# ffmpeg -i rtsp://192.168.1.175:554/11 -acodec aac -strict experimental -ar 44100 -ac 2 -b:a 96k -r 25 -b:v 500k -s 640*480 -f flv rtmp://192.168.1.11:1935/myapp/23
-i 要处理视频文件的路径,此处地址是一个监控摄像头
-s 像素
rtmp://192.168.1.11:1935/myapp/23 说明:rtmp://IP:PORT/ myapp指nginx配置文件中自定义的,22指输出文件的名字
-f 强迫采用flv格式
别的参数参考上面那位老兄的

(2)打开VLC 媒体——>流——>网络

(3)进入服务器查看输出的位置可以发现已生成文件

# ll /tmp/hls/
total
-rw-r--r-- root root Mar : -.ts
-rw-r--r-- root root Mar : -.ts
-rw-r--r-- root root Mar : -.ts
-rw-r--r-- root root Mar : -.ts
-rw-r--r-- root root Mar : .m3u8

(4)还可以使用浏览器这样访问 http://192.168.1.11/hls/22.m3u8
