HTML5 is the standard technology used for embedding videos on modern websites. However, when your browser fails to play a video, it may display Error Code 4, meaning:
“The video file cannot be played.”
This typically indicates that the video format is unsupported or the required codec is missing in your browser.
🔹 2. Why Does HTML5 Video Error Code 4 Occur?
There are several reasons for this error:
🔹 Unsupported Video Format – The browser doesn’t support the video file type (e.g., .MKV, .AVI).
🔹 Missing Codecs – The required codec (like H.264, VP9) isn’t installed or supported.
🔹 Corrupted Video File – The video file itself is damaged or incomplete.
🔹 Browser Compatibility Issues – Some browsers support different video formats.
🔹 Outdated Browser – Older browser versions may lack support for modern codecs.

To convert your video:
✔ Use HandBrake, VLC, or Online Video Converters to convert it to MP4 (H.264).
📌 🔹 Solution 2: Try a Different Browser
Test the video on Chrome, Firefox, Edge, and Safari to see if it works elsewhere.
📌 🔹 Solution 3: Update Your Browser
Ensure you’re using the latest version of your browser for maximum compatibility.
