const NodeMediaServer = require('node-media-server');

const config = {
  rtmp: {
    port: 1935,
    chunk_size: 60000,
    gop_cache: true,
    ping: 30,
    ping_timeout: 1000
  },
  http: {
    port:8083,
    allow_origin: '*'
  },
  https: {
    port: 8446,
    key:'F:\\ssl\\ivynetcircle_privatekey.key',
    cert:'F:\\ssl\\ivynetcircle.com-cert.pem',
    allow_origin: '*'
  },
  auth: {

var nms = new NodeMediaServer(config)
nms.run();

nodeJS node-media-sevice官网说要
3.expiration time: 2017/8/23 11:25:21 ,The calculated expiration timestamp is

1503458721

4.The combination HashValue is:

HashValue = md5("/live/stream-1503458721-nodemedia2017privatekey”)
HashValue = 80c1d1ad2e0c2ab63eebb50eed64201a

5.Final request address

rtmp://192.168.0.10/live/stream?sign=1503458721-80c1d1ad2e0c2ab63eebb50eed64201a
The 'sign' keyword can not be modified
请问ffmpeg要如何推流

```
ffmpeg.exe -re -i .\test.mp4 -c copy -f flv rtmp://hostname.com:1935/live/stream?sign=1503458721-80c1d1ad2e0c2ab63eebb50eed64201a
是这样吗？谢谢

我用localhost是可以实现的 就是不知道如何用hostname和ip形式实现 谢谢
