how to install H.264 (High Profile) decoder for parole media player

on my pc running KDE I tried to use Parole Media Player 4.16.0, A modern simple media player for the Xfce Desktop Environment. but it says me this:
Parole needs H.264 (High Profile) decoder to play this file.
It can be instaalled automatically.
but if I click on install it doesn’t install nothing.
how can I install H.264 (High Profile) decoder?
