👉Follow these steps to disable hardware acceleration:
- Open Google Chrome and click the three dots at the upper-right corner.

Putting the browser in Safe Mode is a very effective method to fix the HTML: video not found error. The Safe Mode is a diagnostic tool that detects the problem of the browser and attempts to repair it.
When you initiate the Safe Mode in your browser, certain settings changes will be made, such as:
- The hardware acceleration will be automatically turned off.
- All plug-ins and add-ons will be disabled.
If a video with HTML5 plays without any error or interruption in Safe Mode, you should check the browser for the changed settings to note where the problem is coming from.
👉Here’s how to fix HTML5 video not found by restarting the browser in Safe Mode:
- Open Google Chrome and click the three dots at the top-right corner.
- Select More Tools and click Extensions.
