Fix: Encrypted Format Windows Error 0xc00d5212. Some Windows 10 users have noticed error 0xc00d5212 (0xc00d5212) when trying to play AVI video in both Windows Media Player and Windows 10 Movies and TV apps. When the video is launched, it will show an error code with the message Cannot play. Items are encoded in an unsupported format.
It’s not clear exactly why the error is such, but it’s mostly likely related to the display driver or video codec. We will fix this issue in 3 ways including updating graphics driver, reinstalling sound driver, updating Windows and using VLC, an alternative media player.
