How can you resolve could not play video with HTML5_video:4 error on iPhone?

What is the HTML5_video:4 Error?

The HTML5_video:4 error pops up when Safari can’t load a video. It’s like getting a “This media resource could not be loaded” sign. Usually, this happens because the video is missing from the server or Safari can’t fetch it properly. Sometimes, the issue might be on your end. Maybe there’s a bug in Safari or a compatibility hiccup. Other times, it could be that the video itself is not available or improperly hosted.

How to Fix the HTML5_video:4 Issue on iPhone

Fixing this error isn’t straightforward. If the video is gone, there’s little you can do. You might reach out to the website, but responses can be slow. If it’s a problem with your device, here are some steps to try:

Solution 1: Update iOS

Keeping your iPhone updated is key. Sometimes, updates cause issues like this, but they often also include fixes. To check for updates:

  1. Go to Settings > General > Software Update.
  2. Install any available updates.
  3. After updating, revisit Safari and see if the video plays.

Solution 2: Check the Video File

The problem might be with the video itself:

  • Unsupported Formats: Safari likes MP4 files with H.264 video and AAC audio. If it’s in WebM or MKV format, it won’t play.
  • Broken Links: If the video link is broken or permissions are off, you’ll hit a wall.
  • Corrupted Files: Sometimes videos just don’t work because they’re damaged.
  • Server Issues: The server might not be set up correctly to serve that file.

Solution 3: Try Another Browser

Switching browsers can help you figure out where the problem lies:

  1. Open another browser like Google Chrome or Opera on your iPhone.
  2. If it plays there, Safari is likely the issue. If not, it’s probably a problem with the video itself.

Soltion 4: Check Internet Connection

A shaky internet connection can ruin your video experience:

  • Make sure you’re connected to Wi-Fi or cellular data.
  • Test other apps or websites to see if they load properly.
  • If your connection is weak, troubleshoot your Wi-Fi or cellular settings.

Solution 5: Disable Safari Extensions

Extensions can mess with playback:

  1. Go to Settings > Safari > Extensions.
  2. Turn off all extensions and then try playing the video again.

Solution 6: Clear History and Website Data

Sometimes old data causes issues:

  1. Open Settings, scroll down to Safari, and tap on Clear History and Website Data.
  2. Confirm this action and reload Safari.

Troubleshooting the HTML5_video:4 error can feel like solving a puzzle. Whether it’s a bug in Safari, a faulty video file, or something server-related, these steps should help you narrow down the issue. If it turns out to be on your side, hang tight for that next iOS update!
