const config = {
  rtmp: {
    port: 1935,
    chunk_size: 60000,
    gop_cache: true,
    ping: 60,
    ping_timeout: 30

    port: 8000,
    allow_origin: '*'
  }
};

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

Todo

直播发布

使用 FFmpeg 推流

如果你有一个音视频编码为H.264+AAC的视频文件转为直播:

ffmpeg -re -i INPUT_FILE_NAME -c copy -f flv rtmp://localhost/live/STREAM_NAME

或者有个其他编码格式，需要转为h.264+AAC的编码再转直播:

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

使用 OBS 推流

Settings -> Stream

Stream Type : Custom Streaming Server

URL : rtmp://localhost/live

Stream key : STREAM_NAME

播放直播流

RTMP 流格式

ffplay rtmp://localhost/live/STREAM_NAME

http-flv 流格式

ffplay http://localhost:8000/live/STREAM_NAME.flv

使用 flv.js 播放 http-flv 流格式

<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>

使用 flv.js 播放 websocket-flv 流格式

<script src="https://cdn.bootcss.com/flv.js/1.3.3/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>

鉴权验证

加密后的 URL 形式:

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.原始推流或播放地址:

rtmp://192.168.0.10/live/stream

2.配置验证秘钥为: 'nodemedia2017privatekey'，同时打开播放和发布的鉴权开关

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.请求过期时间为: 2017/8/23 11:25:21 ,则请求过期时间戳为:

1503458721

4.md5计算结合“完整流地址-失效时间-密钥”的字符串:

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

5.最终请求地址为

rtmp://192.168.0.10/live/stream?sign=1503458721-80c1d1ad2e0c2ab63eebb50eed64201a
注意：'sign' 关键字不能修改为其他的

RTMP协议传输H.265视频

H.265并没有在Adobe的官方规范里实现，这里使用id 12作为标识，也是国内绝大多数云服务商使用的id号
PC转码推流: ffmpeg-hw-win32
手机播放:NodeMediaClient-Android and NodeMediaClient-iOS
纯JavaScrip 直播播放器: NodePlayer.js

事件回调

......
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 视频加密传输

生成证书

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

配置 https支持

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();

播放加密传输视频

转 HLS/DASH 直播流

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,
    mediaroot: './media',
    allow_origin: '*'
  },
  trans: {
    ffmpeg: '/usr/local/bin/ffmpeg',
    tasks: [
      {
        app: 'live',
        ac: 'aac',
        hls: true,
        hlsFlags: '[hls_time=2:hls_list_size=3:hls_flags=delete_segments]',
        dash: true,
        dashFlags: '[f=dash:window_size=3:extra_window_size=5]'
      }
    ]
  }
};

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

直播录制为MP4文件

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,
    mediaroot: './media',
    allow_origin: '*'
  },
  trans: {
    ffmpeg: '/usr/local/bin/ffmpeg',
    tasks: [
      {
        app: 'vod',
        ac: 'aac',
        mp4: true,
        mp4Flags: '[movflags=faststart]',
      }
    ]
  }
};

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

Rtsp/Rtmp 中继

NodeMediaServer 使用ffmpeg实现RTMP/RTSP的中继服务。

静态拉流

静态拉流模式在服务启动时执行，当发生错误时自动重连。可以是一个直播流，也可以是一个本地文件。理论上并不限制是RTSP或RTMP协议

relay: {
  ffmpeg: '/usr/local/bin/ffmpeg',
  tasks: [
    {
      app: 'cctv',
      mode: 'static',
      edge: 'rtsp://admin:admin888@192.168.0.149:554/ISAPI/streaming/channels/101',
      name: '0_149_101'
    }, {
        app: 'iptv',
        mode: 'static',
        edge: 'rtmp://live.hkstv.hk.lxdns.com/live/hks',
        name: 'hks'
      }, {
        app: 'mv',
        mode: 'static',
        edge: '/Volumes/ExtData/Movies/Dancing.Queen-SD.mp4',
        name: 'dq'
      }
  ]
}

动态拉流

当本地服务器收到一个播放请求，如果这个流不存在，则从配置的边缘服务器拉取这个流。当没有客户端播放这个流时，自动断开。

relay: {
  ffmpeg: '/usr/local/bin/ffmpeg',
  tasks: [
    {
      app: 'live',
      mode: 'pull',
      edge: 'rtmp://192.168.0.20',
    }
  ]
}

动态推流

当本地服务器收到一个发布请求，自动将这个流推送到边缘服务器。

relay: {
  ffmpeg: '/usr/local/bin/ffmpeg',
  tasks: [
    {
      app: 'live',
      mode: 'push',
      edge: 'rtmp://192.168.0.10',
    }
  ]
}
