Ubuntu Oneiric Restricted 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.
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.
