Intel UHD 770 Windows Media Player Problem

[OnurCanci]

Hello

When I try to open a video with mp4 extension on Windows media player, it doesn't show the video, but I can hear the audio of the video.  

If I disable the Intel UHD 770 video card, the video plays. If I plug in an external graphics card, it still turns on.

Even if the driver is disable or enable, other media players can show the video and audio. But Windows Media player can't. 

How can we fix this issue?

Operating System: Windows 10 LTSC 2019 (1809)
Driver Version:31.0.101.3616 and 31.0.101.4255

Thanks

Regards.

Hello Friend

The issue you're experiencing with Windows Media Player not showing video but playing audio for an MP4 file, while other media players work fine, suggests a possible issue with the video codecs or the graphics driver settings. Here are some steps you can take to resolve the issue:

1. Update Graphics Driver: Ensure you have the latest driver for your Intel UHD 770 video card.You can check for updates via Windows Update or download the latest driver from the Intel website.
2. Install Codecs: Windows Media Player may require additional codecs to play certain video formats. You can install the necessary codecs by downloading a codec pack like K-Lite.
3. Disable WMV DirectX Video Acceleration: Sometimes, disabling the WMV DirectX Video Acceleration feature in Windows Media Player can resolve playback issues. To do this, open Windows Media Player, go to 'Tools' > 'Options' > 'Performance' and uncheck the 'Turn on DirectX Video Acceleration for WMV files' option.
4. Run the Troubleshooter: Use the built-in Windows troubleshooter for playing audio and video. Go to 'Settings' > 'Update & Security' > 'Troubleshoot' > 'Playing Audio' and run the troubleshooter.
5. Reinstall Windows Media Player: If none of the above solutions work, you might consider reinstalling Windows Media Player. You can do this by going to 'Control Panel' > 'Programs and Features' > 'Turn Windows features on or off' and then uncheck Windows Media Player, restart your computer, and then re-enable it.

Remember to create a system restore point before making any changes to your system, so you can revert back if necessary. If the issue persists after trying these steps, you may want to consider using an alternative media player that supports a wider range of video formats and codecs.
