1. 服务地址（私有）：https://gitee.com/nnlss/video-node-server
2.node-rtsp-stream 需要安装FFMPEG；
3.给推拉流做了开关，可借助http请求，有更好方式可联系；
 

4.存在问题：

1）.对于网络摄像头，直接推拉流，测试6h+界面不卡顿，延迟1s以内（未精确测试延迟时间）

2）.对于物料上的rstp, 由于工程师一直给rtsp推流，即便node服务结束进程，FFMPEG依然可以获取到rtsp

5.node 服务打包

1. 安装ncc

   npm install -g @zeit/ncc

     2.安装成功

ncc version

     3. ncc 打包node 为单文件

ncc build index.js -o nodeServer

报错：

ncc: Version 0.22.3
ncc: Compiling file index.js
Error: error:0308010C:digital envelope routines::unsupported

原因：node 版本问题node.js - Error message "error:0308010C:digital envelope routines::unsupported" - Stack Overflow

利用nvm 切换版本 

nvm use 16.15.0

重新打包：

ncc build index.js -o nodeServer

生成文件目录nodeServer/index.js：

-nodeServer

       --index.js

cmd进入目录执行：

node index.js

启动服务成功
