+===== Install all multimedia codecs =====
+Ubuntu provides a meta-package named **ubuntu-restricted-extras** that consists of most of the common audio and video codecs along with some other packages like the Microsoft fonts.
+  * Install this package and this should resolve most media codecs issues.
+<code bash>
+sudo apt install ubuntu-restricted-extras
+</code>
+<WRAP info>
+**NOTE:**  Since this meta-package contains software from Microsoft, you will have to accept the End User License Agreement (EULA).
+  * With the multimedia codecs installed, most media files should be able to be played (almost).
+    * This includes, mp4 and mkv video files; as well as mp3 music files.
+</WRAP>

+===== Install the Bad gstreamer plugin =====
+<code bash>
+sudo apt install gstreamer1.0-plugins-bad
+</code>
+<WRAP info>
+**NOTE:**  Once this package is installed, open the video file again and see if it works now.
+There is the option to click on the **Find in Ubuntu Software** button, but suggested not to.
+  * Clicking on that option opens the Software Center and it may (or may not) show some packages that will install the h264 decoder on your system.
+  * But it is not easy knowing which package to select in this case.

+====== Install more decoders ======
+There may be other video files that also require some other decoder.
+<code bash>
+sudo apt install libavcodec-extra gstreamer1.0-plugins-ugly gstreamer1.0-libav
+</code>
+----
+====== Optionally, install a better video player (recommended) ======
+Install vlc or mpv.
+<code bash>
+sudo apt install vlc
+or
+sudo apt install mpv
+</code>
