I am running Ubuntu 12.04, and have installed all restricted packages and 354 MB of available updates. However, I still am not able to play video's.

Is it because of low Memory (RAM)?

My Computer Specifications are:

  • 512MB Memory (RAM)
  • 1.15GHZ Prcessor

With what video player are you trying to play with? What errors do you get? – hakermania Aug 25 '12 at 13:31

To install all the restricted packages you are required to install ubuntu-restricted-extras.

sudo apt-get install ubuntu-restricted-extras

It will install the following packages:

  • flashplugin-installer
  • gstreamer0.10-ffmpeg
  • gstreamer0.10-fluendo-mp3
  • gstreamer0.10-pitfdll
  • gstreamer0.10-plugins-bad
  • gstreamer0.10-plugins-ugly
  • gstreamer0.10-plugins-bad-multiverse
  • gstreamer0.10-plugins-ugly-multiverse
  • icedtea6-plugin
  • libavcodec-extra-52
  • libmp4v2-0
  • ttf-mscorefonts-installer
  • unrar

You should be able to play mp4 videos after this. If not, install vlc and try opening the videos in it.

sudo apt-get install vlc

You may be seeing this bug in 12.04 -

To test you can move a specific plugin to a .bak, then try totem on the file. If it then plays you're affected. The moving of the plugin is NOT a solution though many have used it as a temp workaround.

To TEST on 64 bit install

sudo mv /usr/lib/x86_64-linux-gnu/gstreamer-0.10/ /usr/lib/x86_64-linux-gnu/gstreamer-0.10/

To revert the above move

sudo mv /usr/lib/x86_64-linux-gnu/gstreamer-0.10/ /usr/lib/x86_64-linux-gnu/gstreamer-0.10/

To TEST on 32 bit install

sudo mv /usr/lib/i386-linux-gnu/gstreamer-0.10/ /usr/lib/i386-linux-gnu/gstreamer-0.10/

To revert

sudo mv /usr/lib/i386-linux-gnu/gstreamer-0.10/ /usr/lib/i386-linux-gnu/gstreamer-0.10/


And if you're facing that problem , you'll have to use a different player. Like VLC.

Most of the time, when you open up the video file in a player in Ubuntu, there must come a pop up message telling you - you are unable to watch the video, and then instruct you to install the right extension (Third party) .Mp4 plug-in so you will be able to watch that video

If you are not getting that, you can also look for a specific extension / plug-in that can do the job. Otherwise try installing VLC Media player, most time VLC can play almost everything....

I guess I have similar experience with the following error message:

"Package dependencies cannot be resolved

This error could be caused by required additional software packages which are missing or not installable. Furthermore there could be a conflict between software packages which are not allowed to be installed at the same time."
