⚡ How to Fix Unsupported Encoding Settings in Media Player

The fastest way to get back to watching is often switching players or adding support for the missing codecs. Here are the most effective solutions, starting with the simplest.

To help you choose the best solution quickly, here's a simple overview:

Fix 1. Best Solution: Switch to VLC Media Player

For the vast majority of users, the simplest and most effective fix is to stop using the default Windows Media Player and switch to VLC Media Player. VLC is free, lightweight, and built to handle almost any video format and encoding without issues.

• Download and install VLC Media Player.

• Launch VLC. Click Media > Open File.

  

• Select the video that won't play in Windows Media Player and upload it into VLC.

• Check whether the file opens normally.

In most cases, your MP4 file that won't play in Windows Media Player will open and play smoothly in VLC right away.

Fix 2. Roll Back to Previous Windows Media Player (11.2603.12.0)

If you prefer to keep using Microsoft's Media Player, rolling back to an older, more stable version can resolve the issue, especially the Media Player 0x80070057 codec error. Many users have successfully fixed the problem by going back from version 11.2604.9.0 to 11.2603.12.0.

• Go to Settings > Apps > Installed apps, uninstall the current Media Player version.

  

• Restart your computer.

• Install the previous stable version (11.2603.12.0).

  

This fix has worked well for many users facing the error after updates.

Fix 3. Repair or Reset Windows Media Player

Sometimes the error is caused by a temporary glitch in the app itself. Repairing or resetting Media Player is a quick step worth trying.

• Open Settings > Apps > Installed apps.

• Find Media Player, click the three dots next to it, and select Advanced options.

• Click Repair first. If the issue continues, try Reset.

  

• Restart your PC and test your video again.

Fix 4. Install Missing Codec on Windows

A missing codec is one of the most common reasons why encoding settings aren't supported messages appear. If Media Player cannot decode the video stream, installing the correct codec often solves the problem immediately.

Option 1: Install Microsoft HEVC Video Extension

Many smartphones, drones, and cameras now record videos using HEVC (H.265). Windows does not always include HEVC support by default. Thus, you can install this HEVC Video Extension manually from Micorsoft Store.

• Open the Microsoft Store, search for "HEVC Video Extensions".

• Install the free version from Microsoft. This often fixes compatibility issues with modern MP4 files.

• Open your browser and go to the official website.

• Choose the version you want: Standard (Recommended for most users) or Full (If you need more codecs and tools). Then click Download.

  

• Right-click the file and select Run as administrator to run the installer.

• Select Advanced install mode and click Next.

  

• Then follow the prompts (you can keep the recommended settings).

• Click Install and restart your computer when finished.

Fix 5. Change the Problem Video's Format

Converting the video to a more standard format is one of the most reliable ways to fix the unsupported encoding settings MP4 error permanently.

This method works especially well for videos from smartphones, action cameras, or editing software.

• Select the Fast 1080p30 preset.

• Choose MP4 as the container and H.264 as the video codec.

• Click Browse to set the destination file, then hit Start Encode.
