For video playback problem in video player or WhatsApp videos you can try to uninstall Google Plus updates.
Go to Settings>Apps/Application manager>Google Plus app>Uninstall Updates. There is a weird relation between video playing and G+ app, most probably the G+ updates modify some system files causing the problem. Check for video file format and make sure it is with •(dot) extension.

Clearing cache can also resolve the problem. Go to Setting>App manager>YouTube>Clear Cache. You can also uninstall the Twitter app, reboot device and check for YouTube. For other streaming services like from Facebook make sure you have not enabled video playing only when connected to wifi.
