Simple Answer:
You can directly play with VLC or any player if you have modern laptop or computer containing minimum Intel 6th generation “Skylake” or newer CPUs. AMD 6th generation “Carizzo” or newer APUs but if you have slow or old computer then
On PC click the link for the "Ninite K-Lite Codecs Unattended Silent Installer and Updater", which I have included. It will go to the Ninite website with an installer for my prefered player MPC-HC x64 and the KLite Codec pack.
Ninite, installs the correct software for your system, with none of the bundled ware, and all the annoying settings turned off.This is the exact file I put on all three of my machines to play back videos.

Longer Answer:
This next-generation video format/codec H.265/HEVC is one of the best and more advanced codecs than the current popular format H.264. It's named HEVC which stands for High Efficiency Video Codec and offers much better compression when comparing with H.264 (Lower file size, far better quality).

If you want to play this smoothly, you need to use a device/PC with at least dual-core processor. You have to update your player to latest version. Also if you use your PC to watch it, installing LAV Filter will help you a lot if you want to use KMPlayer or PotPlayer. Many updated players have native support for the codec.

If your Device doesn't support H.265 you can try updating your firmware or you can hook your Laptop or x265 compatible device to the TV with HDMI or Wireless connection and stream the video.

Smart TV's: popular brands like LG ,Samsung,Sony and Panasonic TVs can play these files directly. These have all played correclty on a HEVC playback is supposed to be a requirement for all 4K TVs as well.

A tip for users, Windows stupidly defaults all audio to 2ch. For the best experience you need to adjust your sound settings in several locations.
Playback Devices-> Configure - Set to match your phyical speaker set up.
Playback Devices-> Properties-> Advanced - Increase sound output fidelity to your liking.
LAC Audio Decoder-> Mixing - Set speaker configuation to physical.

To play on Android, use MX Player
