Causes of Corrupted MP4 on Android
Before we tackle the subject of how to fix corrupted MP4 files on Android, let’s examine what causes corrupted MP4 on Android
Knowing the causes of a broken MP4 on your Android smartphone or device will help you prevent a similar occurrence in future.
Your Mobile Device Switches Off While Shooting
This could happen for two reasons. First, it’s because of low battery power.
The second reason could be due to your Android Smartphone overheating. As a safety precaution, to prevent damage to your phone, it automatically turns off.
When your phone is suddenly turned off, the system is unable to save the header information of the video you were recording. As a result, your Android device is unable to play the video.
Causes of MP4 Header Corruption
As is usually the case, when you manually stop recording a video, the header information is generated and saved in the system.
Header Information Can’t Be Generated
It is this header information that makes possible the playback of the video.
So, when the phone is switched off before a video recording is manually stopped, the header couldn’t be created and registered in the video file.
.When you try playing the video, you get an error message. This is a sign of MP4 header corruption.
To prevent this from happening, keep your phone battery power at a reasonable level when shooting an important video.
To prevent overheating, turn off other apps when shooting and also exit your video camera app when you’re not shooting to keep your phone temperature at a reasonable level.
Camera App Crash
Camera Apps are subject to instability. For no reason they could act up and stop working altogether.
When this happens in the midst of a video recording, you’ll end up with a corrupted MP4 file because the header doesn’t contain the complete video information required to play it back.
To avoid this, close all other apps when recording video with your Android smartphone or tablet.
Also undertake the necessary camera app updates to ensure it works stably.
Low on Storage Space
Recording video when your storage space is low puts you at the risk of ending up with a corrupted MP4 file.
The system stops recording abruptly when storage space hits a critical level. When this happens, the header information can’t be generated and the video becomes unplayable.
Most of us keep recording videos freely without worrying about the amount of storage space they take up. Smartphones these days could record in Full HD mode which eats up gigabytes of space within a short period of time. So, always keep an eye on your available storage space every now and then.
Before shooting an important event, free up a few gigabytes of space by backing up the files to an external storage device or to your computer hard disk.
Other Reasons for Corrupted MP4 Files on Android
The following are more reasons for the corruption of the Android MP4 file especially when the file is downloaded from an external source like a cloud service.
- The MP4 file was not fully downloaded.
- The Android SD card on which your MP4 file is stored is corrupted.
- Connection terminated when your MP4 file is transferred or downloaded.
- Your Android device is infected with a virus.
- A malicious or ‘rogue’ app is interfering with your MP4 playback.
Can VLC Player Fix Corrupted MP4 Files on Android?
The free VLC Media Player requires no introduction to anyone who uses or produces audio or video.
It’s said that VLC Media Player can play any video or audio file format thrown at it.
This is true to a certain extent. It’s known for its capability to play partially downloaded video files and other types of problematic video files not playable elsewhere.
Before you try other ways to fix corrupted MP4 files on Android, give the VLC video repair option a try.
Unfortunately, VLC player can’t play a corrupted MP4 file from an Android device.
Reason? As has been explained, the header information required to play an MP4 file is absent in a corrupted MP4 file.
