Playing H-265 Videos on Ubuntu 14.04.

While installing Ubuntu 14.04 if you check for installation of proprietary codecs  most videos could be played on Videos application but those having H-265 won't play. For playing them you need to install gstreamer1.0-libde265 as follows.
Open a terminal:

sudo add-apt-repository ppa:strukturag/libde265
sudo apt-get update
sudo apt-get install gstreamer1.0-libde265

Enjoy!
