I experienced the same error, when I passed raw data to createObjectURL:

window.URL.createObjectURL(data) 

It has to be a Blob, File or MediaSource object, not data itself. This worked for me:

var binaryData = []; binaryData.push(data); window.URL.createObjectURL(new Blob(binaryData, {type: "application/zip"})) 

Check also the MDN for more info: https://developer.mozilla.org/en-US/docs/Web/API/URL/createObjectURL


UPDATE

Back in the day we could also use createObjectURL() method with MediaStream objects. This use has been dropped by the specs and by browsers.
If you need to set a MediaStream as the source of an HTMLMediaElement just attach the MediaStream object directly to the srcObject property of the HTMLMediaElement e.g. <video> element.

const mediaStream = new MediaStream(); const video = document.getElementById('video-player'); video.srcObject = mediaStream; 

However, if you need to work with MediaSource, Blob or File, you still have to create a blob:// URL with URL.createObjectURL() and assign it to HTMLMediaElement.src.

This error is caused because the function createObjectURL no longer accepts media stream object for Google Chrome

I changed this:

video.src=vendorUrl.createObjectURL(stream); video.play(); 

to this:

video.srcObject=stream; video.play(); 

This worked for me.

My code was broken because I was using a deprecated technique. It used to be this:

video.src = window.URL.createObjectURL(localMediaStream); video.play(); 

Then I replaced that with this:

video.srcObject = localMediaStream; video.play(); 

That worked beautifully.

EDIT: Recently localMediaStream has been deprecated and replaced with MediaStream. The latest code looks like this:

video.srcObject = new MediaStream();

Video with fall back:

try {   video.srcObject = mediaSource; } catch (error) {   video.src = URL.createObjectURL(mediaSource); } video.play();

I had the same error for the MediaStream. The solution is set a stream to the srcObject.

From the docs:

Important: If you still have code that relies on createObjectURL() to attach streams to media elements, you need to update your code to simply set srcObject to the MediaStream directly.
