    Play MP4 in Media PLayer

    Since Win 10 update I can longer play MP4 videos I used to be able to play in Win 7, using Windows Media Player.

    Why has this function stopped? I thought win 10 was an "improvement".

    This is the error message - Windows Media Player cannot play the file. The Player might not support the file type or might not support the codec that was used to compress the file.

    I do not wish to use VLC player.

    This maybe issue with some mp4, not all as i can see trying one, could be how it was made that particular mp4 ,codec used. Have you tried others ? Also Movies & TV app should also play mp4.

    They all used to work in Media player when I had Win 7. Nothing has changed apart from Win 10 being installed.

    Movies/tv does not play them either.

    I am using mp4 files myself. Rather heavily. The files I have use the native h264 codecs for video and also something pretty standard for audio and they work. MP4 is a container format and I vaguely remember I once had a file, that did not play.

    I am not a real expert here, but you can try this:

    Download the static Windows version of ffmpeg and check your mp4 file with ffprobe.exe. It will output a bunch of information about that file, including the codecs used inside it. Knowing these codecs is a first step on the way to a solution.

    Try and turn Media Player off and then back on again in 'Turn Windows features on and off'

    If you insist on using WMP, make sure, you have all the codecs installed.

    Download K-Lite Codec Pack Standard

    Not really the solution with the scalpel, but more the sledge hammer, but if you're satisfied with it, who am I to complain?
