Part 1. Reasons and Solutions for HTML5 Video Not Found
Most of the time, a video can be corrupted by gaining errors from various sources. But there can be many reasons for HTML5, as it is opened using a web browser. With this idea in mind, you have to think about the causes before solving the problems. This part will show the possible causes and, at the same time, the effective methods of repairing HTML5 not working.
- A website issue is one to consider. The embedded videos on the page have backend issues that are not fixed by the developers.
- The browser issues include unsupported codecs, incompatible files with the browser, and overloaded cache and cookies.
- Customized settings restrict the browser from doing a playback with HTML5 videos.
With these problems, you can still fix them by following the solutions below:
Update the Browser
It has been said that an updated browser version often solves the issues. Google Chrome, Firefox, Opera, Safari, and Internet Explorer can only play videos with the latest version. If HTML5 is not playing, better check the steps below to update the browser:
Step 1.
From the browser, click the Ellipsis icon from the top right corner. It is also known as Customize and Control Google Chrome. Select the Help option.
Step 2.
Choose the About Google Chrome option from the submenu. The settings will check for the latest updates. If the Update button is available, click on it to install the software. Do the same thing to the other browsers.
Clear the Browser’s Cookies and Cache
Caches and cookies are helpful tools for faster and more efficient online surfing. But over time, without deleting them on your browser, these temporary files will disrupt your online activities, such as HTML5 video not working on your Mac. Follow the instructions on how to delete cookies and cache files:
Step 1.
Access the settings on your browser. From the left pane, find the Advanced section. Click on it.
Step 2.
Choose the Privacy and Security option. When you open the Clear Browsing Data window, choose the files you want to delete. Then, click the Clear Data button to confirm the deletion.
Deactivate the Hardware Acceleration
As not all functions are helpful, the Hardware Acceleration can make HTML5 videos not found on your browser. Initially, this function is best for high-resolution graphics for videos and games, but it creates lags for the browser. But don’t worry; turning it off only means the GPU is allowed to load the HTML5 video. You can toggle off the Hardware Acceleration with these steps.
Step 1.
Open the Settings app on your browser via the Ellipsis icon from the upper right corner.
Step 2.
Navigate to the Advanced section and open the System tab. Switch off the button for Use Hardware Acceleration When Available. Try to open the HTML5 video again.
Use HTML5-Supported Codecs
How to fix the video not found issue of HTML5 without changing your settings? You can use codecs that support the video format. However, you will need to contact the browser’s developers and request to install a supporting codec for OGG, WebM, and MP4. This can be an alternative solution, but it is easy to install codecs on the browser, and you might take longer to get an answer from the developers.
Connect to a Stable Internet Network
Your WiFi network will always be an important factor when you want to play HTML5 videos. It is recommended to check the signal stability with a strong signal in your surroundings. Furthermore, do not use mobile data if you barely see any progress on the video. To check the WiFi network, here’s what you need to do:
Step 1.
Go to the Settings app on your device and search for the Network & Settings menu.
Step 2.
Once the window is opened, click the Status button under the Network Status section. Check if the solid bars are high on numbers. This means the signal has good strength.
