Part 1. What Causes Missing Codec 0xc00d5212 Error?

As the error message implies, this specific error is very likely caused by the absence of codecs required to play media files.

Reasons for Missing Codec 0xc00d5212 Error on Windows 10/11

1. The codec is missing or incorrect. The 0xc00d5212 error often occurs for AVI, MOV, MKV, and MP4 files as they are container formats containing various video and audio codecs. A codec is software used to decompress and compress videos or audio. If there is a lack of the required codec of your Windows Media Player or Movies & TV app, you can’t play videos on Windows 10/11 but receive a 0xc00d5212 missing codec error prompt.

2. The file format is not supported. Your Windows Media Player or Movies & TV app on Windows 10 or 11 may not recognize your file formats. For example, MOV format is a QuickTime format for native playback on Mac computers, iPhone or iPads, so it is usually hard to play MOV files on Windows 10/11 without third-party help.

3. The file is corrupted. Your video may be damaged or corrupted during downloading, recording, or transferring, so your media player won’t play the corrupted file but pops up 0xc00d5212 Error. Only fixing the corrupted file will solve the issue.

4. The display driver is outdated. If the display driver is outdated, it will cut off the communication between your graphics card and the video display itself, thus resulting the corresponding error.

5. The Windows OS is outdated. Newer Windows OS will have more abilities to handle the updated file formats. So, if the Windows OS is not in the latest version, there will be problems playing newer file formats.
