Stream realtime low-latency h264 video directly to the browser. Comes with a browser player, and streaming server. Uses Broadway browser decoder and player. Ideal for for Raspberry pi cam streaming.
Usage
Server:
const AvcServer = require('ws-avc-player/lib/server')
const { WebSocketServer } = require('@clusterws/cws') // works with ws, legacy uws
const wss = new WebSocketServer({ port: 3333 })
const avcServer = new AvcServer(wss, 640, 480) //initial width and height (it adapts to the stream)
avcServer.setVideoStream(h264Stream)More detailed in example/index.js
Client:
<html>
<body>
<!-- define the element to hold the canvas -->
<div id="video-box" />
<!-- provide WSAvcPlayer -->
<script type="text/javascript" src="WSAvcPlayer.js" />
<script type="text/javascript">
//initialize the player, if useWorker: true, than you must have `/Decoder.js` availible at the root of the domain.
var wsavc = new WSAvcPlayer.default({useWorker:false});
//append the canvas to the box element, you can style the box element and canvas.
document.getElementById('video-box').appendChild(wsavc.AvcPlayer.canvas)
//connect to the websocket
wsavc.connect("ws://" + document.location.host+":3333");
</script>
</body>
