How to Fix Video Not Playing in HTML: Simple Solutions

To fix a video not playing in HTML, ensure you use the correct <video> tag with supported video formats like MP4, and include the controls attribute so users can play it. Also, check that the video file path is correct and the browser supports the video codec.

Why This Happens

Videos may not play in HTML because the browser cannot find the video file, the format is unsupported, or the <video> tag is missing important attributes like controls. Sometimes the file path is wrong or the video codec is not supported by the browser.

html

<video src="video.avi"></video>

Output

No video controls appear and the video does not play.

The Fix

Use the <video> tag with the controls attribute so users can play the video. Use a widely supported format like MP4. Make sure the src attribute points to the correct file path. Optionally, add multiple sources for better browser support.

html

<video controls>
  <source src="video.mp4" type="video/mp4">
  Your browser does not support the video tag.
</video>

Output

A video player with play/pause controls appears and the video plays correctly.

Prevention

Always use supported video formats like MP4, WebM, or Ogg. Include the controls attribute to allow user interaction. Test your video on different browsers to ensure compatibility. Use relative or absolute paths correctly and check spelling carefully. Consider adding multiple <source> tags for fallback options.
