Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

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

var nms = new NodeMediaServer(config)
nms.run();
node app.js

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 veryfast -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/1.5.0/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/1.5.0/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>

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: 30,
    ping_timeout: 60
  },
  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: 30,
    ping_timeout: 60
  },
  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

https://localhost:8443/live/STREAM_NAME.flv
wss://localhost:8443/live/STREAM_NAME.flv

Web浏览器播放自签名的证书需先添加信任才能访问

转 HLS/DASH 直播流

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

const config = {
  rtmp: {
    port: 1935,
    chunk_size: 60000,
    gop_cache: true,
    ping: 30,
    ping_timeout: 60
  },
  http: {
    port: 8000,
    mediaroot: './media',
    allow_origin: '*'
  },
  trans: {
    ffmpeg: '/usr/local/bin/ffmpeg',
    tasks: [
      {
        app: 'live',
        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: 30,
    ping_timeout: 60
  },
  http: {
    port: 8000,
    mediaroot: './media',
    allow_origin: '*'
  },
  trans: {
    ffmpeg: '/usr/local/bin/ffmpeg',
    tasks: [
      {
        app: 'live',
        mp4: true,
        mp4Flags: '[movflags=frag_keyframe+empty_moov]',
      }
    ]
  }
};

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:[email protected]:554/ISAPI/streaming/channels/101',
      name: '0_149_101'
      rtsp_transport : 'tcp' //['udp', 'tcp', 'udp_multicast', 'http']
    }, {
        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',
    }
  ]
}
