Here is a short video on how to fix ‘Can’t play this file’ error on Android,which usually appear because of a corrupt video file
The app used is MP4Fix available in the Google Play store and it’s free.
Also ,you need an extra reference video clip that is also recorded by the same app you used to record the corrupt video.
*****If you couldn’t find the extra video clip needed, then you need to separately record a couple second video with the same settings as that of the corrupt video.
