Part 1. Common Errors for HTML5 Videos Not Playing

HTML5 video is the new file for playing videos on the browser. HTML5 video files became the standard method of putting a video on a web page because the old way, Adobe Flash, was too complex for many users. But users sometimes encounter "HTML5 video not found." What does this indicate?

Here are some of the common errors why the HTML5 videos are not playing:

• HTML5 support of your browser – This issue usually occurs because your browser might not support the HTML5 file format. If you are using the older browser versions, why can you not play HTML5 videos? In addition, your browser might not support the HTML5 codes, which may be why the "HTML5 video not properly encoded" error appears. Therefore, you should update your browser if you encounter this problem.
• Website's backend issue – This issue is relevant to your website code. If a code glitch occurs, the video file cannot be accessed. This problem can only be fixed by the browser's developer or web admin.
• Browser's Compatibility – Another reason the HTML5 video is not playing is your browser's compatibility. This error can appear due to compatibility issues of your video with some web browsers. For instance, a video does not play in Firefox but works completely well in Chrome.
• Cookies and Caches – This cause is not often why webpages stop playing videos. Cookies contain malicious bugs and sometimes cause you to be unable to play HTML5 video files. To resolve this problem, check it by opening a web page in Incognito mode.
• Videos with older contents – This error can happen when a user tries to play an old video file that supports Adobe Flash Player but does not support the HTML5 file format.

These are just some reasons why the HTML5 videos are not playing.
