This is consistent with Microsoft documentation, which says,īy default, the Windows operating system and the Player include a number of the most popular codecs, such as Windows Media Audio, Windows Media Video, and MP3. (By the way, the list of codecs is virtually identical to my Windows 7 PC, which plays all of these files just fine, using the same version of WMP.)

Mpeg4 Decoder DMO, formats MPG4, mpg4, mp42, MP42, binary mpg4decd.dll version 2.1.

Mpeg43 Decoder DMO, formats mp43, MP43, binary mp43decd.dll version 2.1.

WMVideo Decoder DMO, formats WMV1, WMV2, WMV3, WMVA, WVC1, WMVP, WVP2, VC1S, binary wmvdecod.dll version 2.1.

WMV Screen decoder DMO, formats MSS1, MSS2, binary wmvsdecd.dll version 2.1.

Mpeg4s Decoder DMO, formats mp4s, MP4S, m4s2, M4S2, MP4V, mp4v, XVID, xvid, DIVX, DX50, binary mp4sdecd.dll version 2.1.

MP3 Decoder DMO, format 0055, binary mp3dmod.dll version 2.1.

WMAPro over S/PDIF DMO, format 0162, binary WMADMOD.DLL version 2.145.Windows Media Player (Help > About > Technical Support Info) shows that it has the necessary codecs (or, at least, decoders) available for most of these media types. With WMV, Photos plays the first couple frames and then vanishes without a trace. With MTS, Photos plays the first couple frames and then refuses to play the rest, though the application remains responsive. If I load an MP4 into Photos, it plays a couple frames then a spinner appears and starts running, apparently forever. Photos is weird in that it fails in different ways for different media types. In the video cases, the first couple frames of the video appears before the failure message in WMP or M&TV.

The Player might not support the file type or might not support the codec that was used to compress the file. Windows Media Player cannot play the file. The Windows Media Player failure message is: This item is in a format we don't support. Groove M&TV Photos WMPĬhoose something else to play. Most of the media does not play on the new machine. I built a new PC, installed 64-bit Windows 10 Pro, applied updates, and copied a bunch of my media from my old 64-bit Windows 7 PC.
