Know More about HTML5 Video Not Found Issue

Before moving further into fixes for HTML5 video not found, you must have an overview of what HTML5 video is. This section will briefly describe HTMl5, along with the most likely reasons why the problem occurs.

What is HTML5 Video?

HTML5 refers to the improved level of HTML; it integrates video and audio specifications, letting you today watch online videos without any plugins like Adobe Flash. Furthermore, HTML video is covered by browsers and assists in controlling playback using its control functionalities, including stop, pause, adjust volume, autoplay, etc.

The Causes of HTML5 Video Not Found Issue

Finding out why HTML5 videos cannot be found is also important. It will be easier to find targeted techniques to fix the problem if you are aware of the factors that may be accountable.

Poor internet connectivity. Unfortunately, when you have an unstable connection, there’s no way you can play an online video properly, thus leaving you only with the HTML5: Video file not found.

Backend website issues. The problem may be related to the website’s code, for instance, glitches, so you’re getting the HTML5 error.

Browser-related issues. If the HTML5: Video file not found error comes out only in one specific browser, it may be because of compatibility issues. The browser you’ve been using may not support HTML5 video codec.

Cookies & Caches. Over time, cookies and caches are gathered, which can create issues for sites that prevent them from playing videos.

Corrupt video file. It’s possible that the HTML5 video file is faulty, so you’ll be forced to witness an HTML5 error message rather than a flawless playback.

6 Fixes to HTML5 Video Not Found Issue

Although seeing the HTML5: Video file not found notice on the screen is annoying, there are lots of ways to fix this error. Get your online video back on track with the simple yet comprehensive instructions below!

Fix 1. Update Your Web Browser.

Fix 2. Get the Supported Codecs of HTML5

As said, there’s no way the browser can play the video if it doesn't support the codec of the HTML5 video, regardless of whether it uses the latest version.

Otherwise, consider switching to another web browser with WebM player.

Fix 3. Eliminate the Cookies, Caches, and History.
