First of all excuse me for writing in here but I dont really know where to find help in using webtorrent.

Here's my code:

<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8"/>
<script src="webtorrent.min.js"></script>
</head>
<script>
var client = new WebTorrent()
var magnetUri = 'magnet:?xt=urn:btih:b276fac02e3d2da254019ad9d13e41d6108aecab&dn=&tr=udp%3A%2F%2Ftracker.publicbt.com%3A80&tr=udp%3A%2F%2Ftracker.openbittorrent.com%3A80&tr=udp%3A%2F%2Ftracker.ccc.de%3A80&tr=udp%3A%2F%2Ftracker.istole.it%3A80'

client.add(magnetUri, function (torrent) {
  // Got torrent metadata!
  console.log('Torrent info hash:', torrent.infoHash)

  // Let's say the first file is a webm (vp8) or mp4 (h264) video...
  var file = torrent.files[0]

  // Create a video element
  var video = document.createElement('video')
  video.controls = true
  document.body.appendChild(video)

  // Stream the video into the video tag
  file.createReadStream().pipe(video)
})
</script>

I seeded the file in instant.io and I get the following output in console when executing the above code:

"webtorrent " "new webtorrent (peerId 2d5757303034312d366161363464316639396131, nodeId d488495b38918d054d8959b34ffe895ac4b196b8)" " +0ms" webtorrent.min.js:6:2835

Are you using Firefox? Video streaming is only supported in browsers with MediaSource. Try Chrome.

It's the same on both FF and Chrome, thanks for quick reply, I also want to add that no Node.js and Browserify are used, it's only a simple html file with the code I posted.

Ah, try adding &tr=wss://tracker.webtorrent.io to the end of the magnet link you're using.

Nice, it works and the tag is created but I get a: Not allowed to load local resource: blob:null/29e820f6-80ea-44a7-86f3-039ed71f34e2

making the video unreadable

Looks like your browser is blocking blobs from letting you read local files from your disk. Try loading the site from a real server like localhost instead of from a file:/// url.
