video player

[Martin-Hrach]

Hi, I have this code in VS code with notebook, and i am curious, can i play the video? Because i get the html player, but I can not start the video. But mp3 sound i can play here

const path = require('path');
const { display } = require('node-kernel');

const videoPath = path.join(__dirname, 'rick.mkv');
console.log(videoPath);

const html = `
  <video controls>
    <source src="${videoPath}" type="video/x-matroska">
    Your browser does not support the video tag.
  </video> `
;

display.html(html);

Edit: so it work at least with mp4, but there is a problem with sound, there is none in the notebook
