I have this piece of code which takes input the the camera and displays it within the web browser window (works only if served from a web server, not directly by opening a file):

<html>
<body>

<video id="video" width="640" height="480" autoplay="true"></video>

<script>
    var video = document.getElementById('video');
    if (navigator.mediaDevices && navigator.mediaDevices.getUserMedia) {
        navigator.mediaDevices.getUserMedia({video: true}).then(function (stream) {
            video.src = window.URL.createObjectURL(stream);
            video.play();
        });
    }
</script>

</body>
</html>

I'd like to live-stream the video it to a URL (example: to "/publish/?password=" as in )

How do I code that?

Thanks!

Reset to default 4

The best practice approach, especially if you expect to have multiple clients viewing the video is to stream to a video streaming server and then have the video streaming server stream it to the individual clients.

Video streaming servers are available opensource or mercial and are quiet specialised with mechanisms to maximise device coverage and to handle different network conditions and device screen size/resolutions. rebuilding this type of functionality yourself would not be trivial.

Below is an example of the approach using Wowza a mercial streaming server (I have no affiliation to them):

An source example of streaming servers which will support similar approaches is GStreamer:

  • https://gstreamer.freedesktop

Update

Some links with info on using the Janus server. This supports connections from WebRTC clients and includes a streaming plugin:
