Microsoft Media Foundation Codecs contains four possible missing codecs that cause the "This item was encoded in a format that's not supported" that appears primarily in the Movies & TV App when playing videos. Video tutorial available.

While playing your videos in Windows Media Player or the Movies & TV app, you might receive error code 0xc00d5212 with the message "This item was encoded in a format that's not supported." You will then be redirected to purchase the HEVC codecs from Microsoft.

We've collected the missing codecs and made them available for you in one download. You can try to run every one or run the one with the corresponding name of the video file giving you trouble. See our video below for more information about that.

Included in this download are:

MPEG-2 Video Extension

VP9 Video Extensions (may already be installed)

HEVC Video Extensions

AV1 Video Extension

Web Media Extension

HEIF Image Extension

Webp Image Extension

RAW Image Extension

VCLibs


Video tutorial:



Some of these files are no longer included or updated with Windows 10, and Microsoft now charges for some of these once-free apps.

We noticed some websites and video tutorials recommend you download VLC Media Player, but that is an option, not a solution to the problem.
