Properties of the file

I have this video file with the extension .mkv but it is not playing in totem video player and this works in the new versions of VLC(Windows) and I havent tried it on VLC for Ubuntu yet. Is there any way to make this file run on the default totem player?

  • Why don't you just install vlc for Ubuntu? That should work - especially if you already know if works on VLC under windows. sudo apt-get install vlc

I had the exact same problem. This answer here solved the problem.

I followed the last one , i.e,

Install vlc with sudo apt-get install vlc and then install the required plugins to play *.mkv files by sudo apt-get install vlc-plugin-libde265

Note that, if the plugin installation gave you an error of not found, you will need to add it to the repo first

sudo apt-add-repository ppa:strukturag/libde265
sudo apt-get update

Now try opening the file in vlc.

  • Was driving myself crazy with various attempts until I found this solution. "sudo apt-get install vlc-plugin-libde265" works great, after first adding the repository! THANK YOU for posting this solution! May 24, 2016 at 19:54

    Ubuntu 14.04 > Ubuntu software center > Search for VLC > Install directly worked for me. Without additional codecs. Holy ubuntu and holy stackoverflow =)

    @voghDev - Can you make that an Answer? I tried the sudo apt-get install vlc, only to be met with "no apt package 'vlc', but there is a snap with that name." But thanks to your comment, I got it :D

    @voghDev yeah, sorry if my comment wasn't clear. I found it via the GUI following the steps you gave. :)

I found it using the Ubuntu Software Center GUI instead of calling apt via console.

Ubuntu 14.04 > Ubuntu software center > Search for "VLC" > Install

This is whaty worked for me. No additional codecs needed.

Hope it works for you too!


I tried implementing solution given by @severus, but still I got the error. I solved the probelm by installing an additional package using this command.

sudo apt-get install gstreamer0.10-libde265


Please go online (you must have internet connection running) when you try to run that file it will ask to search required codec then say yes it will install required codec, that's it.

Otherwise try this one:

sudo apt-get install ubuntu-restricted-extras
  • I had an active internet connection when I tried to run the file and it said Required plugin could not be found, and I've installed 'ubuntu-restricted-extras' and other video codecs play without any problem Feb 18, 2015 at 6:56

It seems you are missing the ffmpeg plugin for GStreamer. Install it with the following command.

sudo apt install gstreamer1.0-libav
