Proprietary Extras

Proprietary software helps you maximize your Internet experience, but is not open source. The software available includes Multimedia Codecs, Java Runtime Environment, and plug-ins for Firefox.

Restricted Extras

The Ubuntu Restricted Extras will install Adobe Flash Player, Java Runtime Environment (JRE) (sun-java-jre) with Firefox plug-ins (icedtea), a set of Microsoft Fonts (msttcorefonts), multimedia codecs (w32codecs or w64codecs), mp3-compatible encoding (lame), FFMpeg, extra Gstreamer codecs, the package for DVD decoding (libdvdread4, but see here for info on libdvdcss2), the unrar archiver, odbc, and cabextract. It also installs multiple "stripped" codecs and avutils (libavcodec-unstripped-52 and libavutil-unstripped-49). This is a single command approach.

sudo apt-get install ubuntu-restricted-extras

Note: Installation only works completely and properly when done from the command-line Terminal. The entire package will not usually install completely from within a Package Manager.

Java environment

  • See this section for information on installing Java or the Java Runtime Environment.

Playing DVDs

  • See this section for information on packages needed to play DVDs.

Pepper Flash

  • The Pepper Flash (PPAPI) plugin is required to play HTML5 videos on you tube and other sources through the Chromium and Chrome browsers (it is bundled in the Chrome browser already). Installing this plugin through the skunk repository will also install the Chromium v. 37 (or later) browser.
sudo add-apt-repository ppa:skunk/pepper-flash
sudo apt-get update
sudo apt-get install pepflashplugin-installer
  • The alternative is to add the repository directly to your software manager's software sources. See the instructions at the skunk Launchpad repository.
