❌ How to Fix “Stream Format Not Supported” Error (2025)
You click on a movie, and instead of the opening scene, you get a black screen with the message: “Stream
Format Not Supported”.
This means your device is trying to speak French, but the video file is speaking Japanese. They don’t understand each
other.
Here is how to teach your device to play any format.
1. Install VLC Player (The Magic Fix)
Most built-in players can only play basic formats. VLC Player includes every “codec” in the world.
- Download VLC for Android (or Fire Stick).
- Go to your IPTV App Settings.
- Select “External Player”.
- Choose VLC.
Now, when you click the movie, VLC will open and play it perfectly.
VLC plays what others can’t.
2. Change from Hardware to Software Decoding
If you don’t want to install VLC, you can change how your current player works.
In Smarters/TiviMate:
- Go to Settings > Player.
- Find “Decoder”.
- Change it from Hardware (HW) to Software (SW).
Software decoding is slower, but it is compatible with more formats.
3. Update Your App
Are you using an old version of Smarters or TiviMate? New video formats (like HEVC/H.265) are released all the time.
If your app is from 2023, it won’t know how to play a 2025 movie.
The Fix: Uninstall your app and download the latest version from the official website.
Updates bring new codecs.
4. Check Your Internet Speed
Sometimes, “Format Not Supported” is a lie. The real problem is that the video is 4K, and your internet is too slow
to start it.
The app times out and gives you a random error message.
The Test: Try to play a SD (Standard Definition) channel. If it works, your
internet is the problem, not the format.
5. It Might Be the File Itself
If you are trying to watch a specific movie and it fails on every device (Phone, TV, PC), the file on the server is
corrupt.
The Solution: Report it to your provider. There is nothing you can do on your end.
🚀 Conclusion
90% of the time, switching to VLC Player fixes this error instantly. It is the Swiss Army Knife of
video players.
