Error when playback videos on Ubuntu 15.10

 

I have ubuntu 15.10 on my laptop (fresh install) and when i try to open videos/movie i get an error message like this:

Required plugin could not be found
Videos requires to install plugins to play files of the following types:

MPEG-4 AAC decoder
H.264 (Main Profile) decoder

How to fix this issue??

This happened because there is no video decoder available on the system, so we need to install the video decoder.

Go ahead open terminal/ console/ command line (press CTRL + ALT + T), and then type this command:

sudo apt-get install ubuntu-restricted-extras

If you get an error when running the command above, try updating the repo list first, with this command:

sudo apt-get update

or this:

sudo apt-get update --fix-missing

Then run the apt-get install ubuntu-restricted-extras again
