Summary
The URL.revokeObjectURL() static method releases an existing object URL which was previously created by calling URL.createObjectURL(). Call this method when you've finished using an object URL to let the browser know not to keep the reference to the file any longer.
You can call revokeObjectURL() any time after sourceopen is handled. This is because createObjectURL() is merely a means of connecting a media element's src attribute with a MediaSource instance. Calling revokeObjectURL() leaves the underlying objects in place and allows the platform to handle garbage collection at an appropriate time.
Note: This feature is available in Web Workers.
Syntax

- objectURL
- is a
DOMStringrepresenting the object URL that was created by callingURL.createObjectURL().
