[javascript] Failed to execute 'createObjectURL' on 'URL':

Display Below error in Safari.

Failed to execute 'createObjectURL' on 'URL': No function was found that matched the signature provided.

My Code is:

function createObjectURL(object) {
    return (window.URL) ? window.URL.createObjectURL(object) : window.webkitURL.createObjectURL(object);
}

This is my Code for image:

function myUploadOnChangeFunction() { 
    if (this.files.length) { 
       for (var i in this.files) { 
           if (this.files.hasOwnProperty(i)) { 
              var src = createObjectURL(this.files[i]); 
              var image = new Image(); 
              image.src = src; 
              imagSRC = src; 
              $('#img').attr('src', src); 
            }
       }           
   } 
} 

Video with fall back:

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

From: https://developer.mozilla.org/en-US/docs/Web/API/HTMLMediaElement/srcObject

The problem is that the keys provided in the loop do not refer to the index of the file.

for (var i in this.files) {
    console.log(i);
}

The output of the above code is:

0
length
item

But what was expected was:

0
1
2
etc...

Then the error occurs when the browser tries to execute, for example:

window.URL.createObjectURL(this.files["length"])

I suggest implementation based on the following code:

var files = this.files;
for (var i = 0; i < files.length; i++) {
    var file = files[i],
        src = (window.URL || window.webkitURL).createObjectURL(file);
    ...
}

I hope this can help someone.

Greetings!

If you are using ajax, it is possible to add the options xhrFields: { responseType: 'blob' }:

$.ajax({
  url: 'yourURL',
  type: 'POST',
  data: yourData,
  xhrFields: { responseType: 'blob' },
  success: function (data, textStatus, jqXHR) {
    let src = window.URL.createObjectURL(data);
  }
});

I fixed it downloading the latest version from GgitHub GitHub url

This error is caused because the function createObjectURL is deprecated 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();

References:

1. Deprecated technique: https://developer.mozilla.org/en-US/docs/Web/API/URL/createObjectURL
2. Modern deprecated technique: https://developer.mozilla.org/en-US/docs/Web/API/HTMLMediaElement/srcObject
3. Modern technique: https://developer.mozilla.org/en-US/docs/Web/API/MediaStream

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.
