Hello Linux Geeksters. As you may know, Ubuntu systems do not come with playback support for proprietary file formats, like: HEVC or H.265. The same applies for the derivative systems.
In this article I will show you how to enable the HEVC and H.265 playback on Ubuntu 14.10, Ubuntu 14.04, Ubuntu 12.04 and derivative systems, like: Linux Mint 17.1 Rebecca, Linux Mint 17 Qiana, Pinguy OS 14.04, Elementary OS 0.3 Freya, Elementary OS 0.2 Luna, Deepin 2014, Peppermint Five, LXLE 14.04 and Linux Lite 2.0.
To enable playback support for HEVC and H.265, we have to install the gstreamer1.0-libde265 gstreamer0.10-libde265 packages which are available via some third party PPA:
$ sudo apt-add-repository ppa:strukturag/libde265
$ sudo apt-get update
$ sudo apt-get install gstreamer1.0-libde265 gstreamer0.10-libde265
Or, you can install the vlc-plugin-libde265 plugin, so you will be able to have playback support for the two file formats only inside VLC:
$ sudo apt-get install vlc-plugin-libde265
