What codec do I need to play MP4-Videos on my pc? (offline)

Question

I am new to elementary OS, what codec do I need to play MP4 videos from my storage off-line?

I get this error message: Oops! Audience kann diese Datei nicht wiedergeben! No URI set. (in English: Oops! Audience can't play this file !)
