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)

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>
</html>
