Publishing live streams

From FFmpeg

If you have a video file with H.264 video and AAC audio:

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:

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

ffplay rtmp://localhost/live/STREAM_NAME

via http-flv

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

via flv.js over http

<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: 'http://localhost:8000/live/STREAM_NAME.flv'
        });
        flvPlayer.attachMediaElement(videoElement);
        flvPlayer.load();
        flvPlayer.play();
    }
</script>

via flv.js over websocket

<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>

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.expiration time: 2017/8/23 11:25:21 ,The calculated expiration timestamp is

1503458721

3.Config set auth->secret: 'nodemedia2017privatekey'

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'
  }
}

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.

Event callback

......
nms.run();
nms.on('preConnect', (id, args) => {

  // let session = nms.getSession(id);
  // session.reject();
