How to Fix Stremio Error: “Video is Not Supported”

If you are a fan of seamless movie nights, there is nothing more frustrating than settling in to watch your favorite show only to be met with the dreaded message: “Error: Video is not supported. Open in external player.”

This is not a “game” or a bug in the movie itself; Stremio is a media-streaming aggregator that relies on various add-ons and the built-in video player of your device. When you see this error, it typically means there is a codec mismatch—essentially, the file format of the movie you chose is written in a “language” that your TV or device simply doesn’t speak.

While this happens across many platforms, it is a notorious issue for LG Smart TV users running WebOS, as these televisions often have limited native video codec support compared to a PC or an Android device.

🛠️ Immediate Quick Fixes

Before diving into complex settings, try these “brute force” methods that surprisingly solve the issue for many users:

1. The “Retry” Method

Sometimes the initial handshake between the Stremio app and the source fails.

• Instruction: Simply close the video, go back to the source list, and click it again. Many users report that after 2 or 3 retries, the video suddenly starts playing.

• App Restart: If retrying the file fails, fully close the Stremio app and relaunch it to refresh the cache.

2. The HDMI Reset (For External Devices)

If you are using a PC, Fire Stick, or Chromecast plugged into your TV via HDMI:

• Instruction: Unplug the HDMI cable from the back of the TV while the app is open, wait 5 seconds, and plug it back in.

• Why it works: This forces an HDMI Handshake reset, which can sometimes re-negotiate the video signal and allow supported formats to display properly.

🚀 The Practical Solution: Using an External Player

The internal “Web Player” used by Stremio is convenient but lacks the power of dedicated media software. If your TV or device can’t play the file, you need to “outsource” the work to a specialized app like VLC or MX Player.

Top External Player Recommendations:

• VLC Media Player: The “universal” choice available on almost every platform.

• MX Player: Excellent for Android-based TVs and mobile devices.

• Just Player: A lightweight, highly compatible option for Android users.

How to Enable External Player in Settings:

1. Open Stremio Settings.

2. Navigate to the Player tab.

3. Scroll down to the Advanced or General section.

4. Look for “Play in external player”.

5. Set it to Enabled (or select M3U Playlist if on the web version).

6. Now, when you click a movie, Stremio will ask which app you want to use. Select VLC or your chosen player to bypass the Stremio error entirely.

📺 Specific Advice for LG TV Users (WebOS)

LG TVs are notorious for becoming more restrictive with video formats through firmware updates. If the built-in Stremio app on WebOS continues to fail:

• Switch Devices: The internal Smart TV apps are often the weakest link. Consider getting a dedicated streaming device like a Fire Stick 4K, Chromecast with Google TV, or an Apple TV. These devices have much broader codec support than the TV’s built-in software.

• Reinstall the App: Uninstall Stremio from your LG Content Store and reinstall it. This ensures you are on the latest version which may include updated playback libraries.

🔍 Check Your Add-ons

Sometimes the error isn’t about the player, but the source.

• If a specific add-on is down or outdated, it may send a “dead link” that the player interprets as “Unsupported.”

• Action: Try selecting a different source (link) further down the list. If other links work, the issue was with the specific add-on, not your Stremio app.
