Summary: Have you come across the HTML5 video ‘File not found’ error while playing videos on YouTube or any other website? The error usually occurs when your browser does not support the HTML5 format codecs or doesn’t have the proper video codec installed. This blog discusses the methods to fix the error and to make the videos playable again.
What is an HTML5 Video File?
The HTML5 video is a new kind of video element, designed to replace a portion of the original object element. This allows the users to watch videos on websites without the need for any plugins. For this, the webmaster has to create HTML5 coding that corresponds to the links where the video can be downloaded. The formats include OGG, WebM, and MP4. Once your webmaster has created the coding, it gets placed into the body tags of the webpage’s HTML coding. This makes the HTML5 video viewable in all the browsers, such as Google Chrome, Internet Explorer, Firefox, and Safari. If you are downloading these browsers for the first time, then make sure to have the latest updates downloaded for them as well. This guarantees that your browser is compatible to read HTML5 coding on all websites.
Reasons behind HTML5 Video ‘File Not Found Error
There are multiple reasons that may lead to HTML5 Video File Not Found Error:
- Backend Website Issue: The HTML5 Video error may occur when you try to watch a video embedded on a webpage. It is mainly an issue in the backend and can be fixed by the webmaster or developer of the site.
- Browser Issue: Issue in the browser can also result in an HTML5 video error. Here we have mentioned some common scenarios:
- The browser in which you’re playing the video may not support HTML5 format codecs. This can be checked by playing the video in another browser.

How to Fix ‘HTML5 Video: File Not Found Error?
Follow the below-given methods to resolve the issue:
Method 1: Start the Browser in Safe Mode
