I am new to node.js and was debugging a code written by another developer. We have a an IP camera which provides rtsp feed which is being displayed on a webpage. I can view the camera feed using the rtsp url in VLC but the web viewer of camera feed usually gives white screen although it somehow works intermittently.

I was told that it used to work properly when the machine was on Ubuntu 20.04 now it has been updated to Ubuntu 24.

Index.js

const Stream = require("node-rtsp-stream-jsmpeg");
const fs = require("fs");
const https = require("https");

const httpsServer = https.createServer({
  key: fs.readFileSync("./cert/ssl.key"),
  cert: fs.readFileSync("./cert/ssl.crt"),
});


const options = {
    name: "streamName",
    url: "rtsp://10.20.xxx.xx/profile1",
    wsPort: 3333,
    httpsServer: httpsServer
};

let stream = new Stream(options);
stream.start();

index.html

  var url = "ws://localhost:3333";
  var canvas = document.getElementById('video-canvas');
  var player = new JSMpeg.Player(url, {canvas: canvas});
  </script>
</body>

I tried reinstalling the node modules but it didn't make any difference. I am sure that there is no hardware issue as rtsp connection always works in VLC.

Following is the console log when it fails Following is the console log when it works
