Some of the common causes of MP4 file corruption are:

How to Fix Corrupt MP4 Files
You can repair damaged or corrupted videos with the help of MP4 repair software.
But note if a video is not playing or showing an error, it may not necessarily be corrupt. The problem can be with the device or media player you use to play MP4 videos. So, before getting on to a video repair software, try these troubleshooting methods to fix damaged MP4 videos:
Fix Damaged or Unplayable MP4 Videos Without Software
1. Play the video in another Media Player
Media players are not compatible with every video format. Although media players mostly support MP4, technical issues can still occur. So change the media player. Then, play your MP4 files in VLC Media Player, Winamp, KMPlayer, or others.
2. Convert the video file format
If MP4 videos are not playing, convert the file format, such as MP4 to MOV, MP4 to AVI, and so on. You can choose any online MP4 converter program or desktop conversion software like Stellar Converter for Audio Video.
VLC Media Player can also convert MP4 videos to a different file format.
3. Download MP4 Codecs
A codec is used to compress or decompress a video file. Every video file format has an audio and video codec. For example, MP4 file types use MPEG-4 codec to compress video and AAC compression for audio. If your media player doesn’t have these codecs, it cannot play an MP4 file and may show errors, such as ‘A codec is required to play this file.’
The solution is to download the right codecs. You can also get a codec pack online, such as Media Player Codec pack, X codec pack, or K-Lite or Perian for your PC or Mac computer. A pack would contain codecs for most video file types, including MP4.
