# Usage 
```bash
npm install node-media-server
```

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

const config = {
  rtmp: {
    port: 1935,
    chunk_size: 60000,
    gop_cache: true,
    ping: 60,
    ping_timeout: 30
  },
  http: {
    port: 8000,
    allow_origin: '*'
  }
};

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

```

# Todo 
- [ ] support record stream 
- [ ] support transcode
- [ ] support cluster
- [ ] support low latency hls
- [x] server and streams status
- [ ] server monitor frontend
- [x] on_connect/on_publish/on_play/on_done event callback

# Publishing live streams
## From FFmpeg
>If you have a video file with H.264 video and AAC audio:
```bash
ffmpeg -re -i INPUT_FILE_NAME -c copy -f flv rtmp://localhost/live/STREAM_NAME
```

Or if you have a video file that is encoded in other audio/video format:
```bash
ffmpeg -re -i INPUT_FILE_NAME -c:v libx264 -preset superfast -tune zerolatency -c:a aac -ar 44100 -f flv rtmp://localhost/live/STREAM_NAME
```

## From OBS
>Settings -> Stream

Stream Type : Custom Streaming Server

URL : rtmp://localhost/live

Stream key : STREAM_NAME

# Accessing the live stream
## via RTMP 
```bash
ffplay rtmp://localhost/live/STREAM_NAME
```

## via http-flv
```bash
ffplay http://localhost:8000/live/STREAM_NAME.flv
```

## via flv.js over http

```html
<script src="https://cdn.bootcss.com/flv.js/1.4.0/flv.min.js"></script>
<video id="videoElement"></video>
<script>
    if (flvjs.isSupported()) {
        var videoElement = document.getElementById('videoElement');
        var flvPlayer = flvjs.createPlayer({
            type: 'flv',
            url: 'http://localhost:8000/live/STREAM_NAME.flv'
        });
        flvPlayer.attachMediaElement(videoElement);
        flvPlayer.load();
        flvPlayer.play();
    }
</script>
```

## via flv.js over websocket

```html
<script src="https://cdn.bootcss.com/flv.js/1.4.0/flv.min.js"></script>
<video id="videoElement"></video>
<script>
    if (flvjs.isSupported()) {
        var videoElement = document.getElementById('videoElement');
        var flvPlayer = flvjs.createPlayer({
            type: 'flv',
            url: 'ws://localhost:8000/live/STREAM_NAME.flv'
        });
        flvPlayer.attachMediaElement(videoElement);
        flvPlayer.load();
        flvPlayer.play();
    }
</script>
```

# Authentication
## Encryption URL consists of:
> rtmp://hostname:port/appname/stream?sign=expires-HashValue  
> http://hostname:port/appname/stream.flv?sign=expires-HashValue  
> ws://hostname:port/appname/stream.flv?sign=expires-HashValue  

1.Publish or play address:
>rtmp://192.168.0.10/live/stream

2.Config set auth->secret: 'nodemedia2017privatekey'
```js
const config = {
  rtmp: {
    port: 1935,
    chunk_size: 60000,
    gop_cache: true,
    ping: 60,
    ping_timeout: 30
  },
  http: {
    port: 8000,
    allow_origin: '*'
  },
  auth: {
    play: true,
    publish: true,
    secret: 'nodemedia2017privatekey'
  }
}
```
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

# H.265 over RTMP
H.265 does not appear in Adobe's official specification. Id 12 is the standard for most cloud services in China.  
Publish or Transcode: [ffmpeg-hw-win32](#ffmpeg-hw-win32)  
Play:[NodeMediaClient-Android](#android) and [NodeMediaClient-iOS](#ios)  
Pure JavaScrip live stream player: [NodePlayer.js](https://github.com/illuspas/NodePlayer.js)

# Event callback
```js
......
nms.run();
nms.on('preConnect', (id, args) => {
  console.log('[NodeEvent on preConnect]', `id=${id} args=${JSON.stringify(args)}`);
  // let session = nms.getSession(id);
  // session.reject();
});

nms.on('postConnect', (id, args) => {
  console.log('[NodeEvent on postConnect]', `id=${id} args=${JSON.stringify(args)}`);
});

nms.on('doneConnect', (id, args) => {
  console.log('[NodeEvent on doneConnect]', `id=${id} args=${JSON.stringify(args)}`);
});

nms.on('prePublish', (id, StreamPath, args) => {
  console.log('[NodeEvent on prePublish]', `id=${id} StreamPath=${StreamPath} args=${JSON.stringify(args)}`);
  // let session = nms.getSession(id);
  // session.reject();
});

nms.on('postPublish', (id, StreamPath, args) => {
  console.log('[NodeEvent on postPublish]', `id=${id} StreamPath=${StreamPath} args=${JSON.stringify(args)}`);
});

nms.on('donePublish', (id, StreamPath, args) => {
  console.log('[NodeEvent on donePublish]', `id=${id} StreamPath=${StreamPath} args=${JSON.stringify(args)}`);
});

nms.on('prePlay', (id, StreamPath, args) => {
  console.log('[NodeEvent on prePlay]', `id=${id} StreamPath=${StreamPath} args=${JSON.stringify(args)}`);
  // let session = nms.getSession(id);
  // session.reject();
});

nms.on('postPlay', (id, StreamPath, args) => {
  console.log('[NodeEvent on postPlay]', `id=${id} StreamPath=${StreamPath} args=${JSON.stringify(args)}`);
});

nms.on('donePlay', (id, StreamPath, args) => {
  console.log('[NodeEvent on donePlay]', `id=${id} StreamPath=${StreamPath} args=${JSON.stringify(args)}`);
});

# Https/Wss

## Generate certificate
```bash
openssl genrsa -out privatekey.pem 1024
openssl req -new -key privatekey.pem -out certrequest.csr 
openssl x509 -req -in certrequest.csr -signkey privatekey.pem -out certificate.pem
```

## Config https
```js
const NodeMediaServer = require('./node_media_server');

const config = {
  rtmp: {
    port: 1935,
    chunk_size: 60000,
    gop_cache: true,
    ping: 60,
    ping_timeout: 30
  },
  http: {
    port: 8000,
    allow_origin: '*'
  },
  https: {
    port: 8443,
    key:'./privatekey.pem',
    cert:'./certificate.pem',
  }
};


var nms = new NodeMediaServer(config)
nms.run();
```
## Accessing
```
https://localhost:8443/live/STREAM_NAME.flv
wss://localhost:8443/live/STREAM_NAME.flv
```
>In the browser environment, Self-signed certificates need to be added with trust before they can be accessed.
