  • 🗝️Outdated Display Drivers: A display driver is a bridge between a video graphics card and a video display. If you fail to keep it up to date, it cannot perform its duties as required and may bring about this error.
  • 🗂️Corrupted Video Files: If your video files get damaged accidentally, you cannot open them anymore, even when you convert the file format, so you may also receive this error.
  • 🦠Malware or Virus Attack: Malware or virus attack may also be a potential cause of this error code, for it can compromise or erase crucial code needed to run the media player.
  • 🙅‍♂️Conflicts with Third-Party Tools: Conflicts between third-party software and other codec-related apps on your system can result in the 0xc00d5212 problem.
