原创； linux_手把手教ubuntu搭建rtmp视频推送服务
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.
sudo apt-get install libpcre3 libpcre3-dev
报错：./configure: error: SSL modules require the OpenSSL library.
sudo apt-get install openssl libssl-dev
报错：./configure: error: the HTTP gzip module requires the zlib library.
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:
/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
外层:
rtmp
{
server
{
listen 1935;
chunk_size 4096;
application live
{
live on;
}
}
}
http的内层添加:
server {
listen 8080;
location /stat{
rtmp_stat all;
rtmp_stat_stylesheet stat.xsl;
}
location /stat.xsl{
root /home/cjc/安装包/nginx/nginx-rtmp-module-master;
}
}
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
此时nginx的配置如下:
#user nobody;
worker_processes 1;
events {
worker_connections 1024;
}
rtmp
{
server
{
listen 1935;
chunk_size 4096;
application live
{
live on;
}
}
}
http {
include mime.types;
default_type application/octet-stream;
sendfile on;
keepalive_timeout 65;
server {
listen 8080;
location /stat{
rtmp_stat all;
rtmp_stat_stylesheet stat.xsl;
}
location /stat.xsl{
root /home/john/nginx-rtmp-module-master;
}
}
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.
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
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
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.
