软件_搭建rtmp视频推送环境,腾讯云,ubuntu16

1,安装conda,ffmpeg,nginx,nginx-rtmp-module

(建议先修改主机pip,conda的源)
安装conda,创建环境::conda create -n rstp python=3.7
报错:Solving environment: | failed

top可看出内存不足,换个大内存机器

安装ffmpeg:4.0

sudo add-apt-repository ppa:jonathonf/ffmpeg-4
sudo apt-get update
sudo apt-get install ffmpeg
如果使用了:sudo apt-get install ffmpeg(默认2.8),先卸载掉,避免干扰

下载Nginx源码:wget http://nginx.org/download/nginx-1.17.10.tar.gz
下载nginx-rtmp-module:wget github.com/arut/nginx-rtmp-module/archive/master.zip

在nginx源码路径下执行:sudo ./configure –add-module=/home/john/nginx-rtmp-module-master/(注意后面的路径是解压后的rtmp源码路径)
报错:./configure: error: C compiler cc is not found

sudo apt-get install gcc
sudo apt-get install build-essential

报错:./configure: error: the HTTP rewrite module requires the PCRE library.

1
sudo apt-get install libpcre3 libpcre3-dev

报错:./configure: error: SSL modules require the OpenSSL library.

1
sudo apt-get install openssl libssl-dev

报错:./configure: error: the HTTP gzip module requires the zlib library.

1
sudo apt install zlib1g-dev

sudo make
sudo make install
验证:

成功后重启Nginx:systemctl restart nginx,输入机器外网ip,查看是否nginx默认页面

检查是否成功:

1
2
/usr/local/nginx/sbin/nginx -V
是否包含:类似 --add-module=nginx-rtmp-module

访问nginx的welcome,确保nginx安装无问题

2,nginx配置修改

rtmp
{
server

listen 1935;
chunk_size 4096;
application live
{
live on;
}
}
}

http的内层添加:

}
location /stat.xsl{

}
}

报错:nginx: [emerg] unknown directive “rtmp” in /etc/nginx/nginx.conf:12

换nginx版本,本人采用了1.7,同时确保nginx使用的源码方式安装,如果apt-get安装,卸载干净重新安装

location /stat.xsl{

}
}
server {
listen 80;
server_name localhost;

location / {
root html;
index index.html index.htm;
}

error_page 500 502 503 504 /50x.html;
location = /50x.html {
root html;
}
}
}

3,推流和拉流

记得开放虚拟机端口,否则容易悲剧(telnet测试下远程机端口)

终端(循环推送):ffmpeg -stream_loop -1 -i 1.mp4 -f flv rtmp://localhost:1935/live/test1
vlc:rtmp://118.25.10.138:1935/live/test1

奇怪的是:以下参数组也依然好使,端口1935去掉.

2
终端(循环推送):ffmpeg -stream_loop -1 -i 1.mp4 -f flv rtmp://localhost/live/test1
vlc:rtmp://118.25.10.138/live/test1

查了下rtmp默认端口就是1935,所以不加端口,实际就是从1935取得的,故确保远程主机放开端口1935

如何实现多路?
启动多个ffmpeg即可. 需要留意cpu和网络占用情况

1
rtmp://localhost/live/test2,rtmp://localhost/live/test3等等

如何实现帧率控制?
参数-r控制帧率

1
nohup ffmpeg -stream_loop -1 -r 1 -i 3.mp4  -f flv rtmp://localhost/live/3 &

4,docker

查资料时发现,已经有人制作了dofacker,可以直接使用.
