"I am not able to play MP4 video files in WMP (Windows Media Player) 11. It says these files are not supported by WMP. How to play MP4 files in MMP?"
You may have got lots of videos and movies in MP4 format since MP4 is almost the most popular video format that can be played on various multimedia devices like iPhone, iPad, Android, PSP, and more. However, if you want to play MP4 in Windows Media Player 12, 11, 10, or earlier, you may fail. To play MP4 videos in Window Media Player 12/11/10 or earlier, here is the solution.
According to Microsoft support, the older Windows Media Player, such as WMP 11, WMP10, doesn't support MP4 formats. And even though the latest Windows Media Player 12 supports MP4 video and audio files, it doesn't mean that WMP 12 can play all MP4 files. MP4 is a container format which may include multiple video and audio streams. If the video or audio streams are encoded by codecs that are not supported by WMP, the player won't play the MP4 file either.
To solve "MP4 won't be played on Windows Media Player", there are two ways:
Install necessary codecs on Windows Media Player, such as Microsoft MP4 codec.
Convert videos to Windows Media Player supported formats.
However, sometimes even we have the appropriate codec installed, Windows Media Player still cannot play some MP4 files. So the best way to play any MP4 video, audio files on WMP is to convert MP4 to WMV or AVI, formats that are compatible with Windows Media Player
