Android plays audio but not video? Solution

Question

I don't know what happened just of a sudden, my android 5.1 has stopped showing videos. I can play them, have control buttons but only audio plays, and it shows a blank black screen. This is happening everywhere on YouTube, whatsapp, google, fb and even sd card videos.

Any solution please?
