The culprit behind this inconvenience is usually Adobe Flash Player. As the internet browsers often use Adobe Flash to run HTML5 videos, a check on the Flash Player’s activity is recommended.
Here’s how one user described the issue on Microsoft Answers forum:
When I try to play HTML5 videos in IE9, I get the message that Your browser does not support HTML5 video.
NONE of the videos are supported as the video frames give messages that state:
Your browser cannot play H.264 high profile content with the HTML5 video element.
How can I fix this?
We managed to come up with a series of solutions to help you run HTML5 videos in your Internet browser.
How do I get my browser to support HTML5?
1. Use a different browser
If you’re having this problem with your browser, perhaps you should consider switching to a new one.
Opera is heavily focused on user privacy and security, and it offers the same customization options and extensions as Chrome.
Unlike Chrome, this browser is a lot faster, and you won’t have any issues with HTML5 videos while using it. Opera comes with various built-in packages, enhanced resource consumption, and great design.
Moreover, Opera comes with a built-in adblocker so that you can navigate the internet without distractions.
