Configure your node
Open the node's configuration panel to set Input URL and the Stream URL.

ws://<host>:<port>/stream
Using the stream
To render the video stream in the browser, we use a library called JSMpeg.
<html>
<body>
<!-- import JSMpeg -->
<script src="jsmpeg.min.js"></script>
<!-- create a canvas tag to render our video stream -->
<canvas id="video-canvas"></canvas>
<script>
const videoCanvas = document.getElementById('video-canvas')
// The stream URL that we set in the previous step.
const url = `ws://${window.location.hostname}:${window.location.port}/stream`
new JSMpeg.Player(url, { canvas: videoCanvas })
</script>
</body>
