Disclaimer: Patent and copyright laws operate differently depending on which country you are in. Please obtain legal advice if you are unsure whether a particular patent or restriction applies to a media format you wish to use in your country. For legal reasons Ubuntu (as first installed) lacks many of the codecs which are needed to play some of the many possible audio or video formats available. This is because of global, geographical, variations in legislation regarding intellectual property, security and other issues. Before following any of the procedures offered in here, please note that immediately after installation it is recommended to first download any security updates which are available to date. If you do not see a pop up offer for this then use System>Administration>UpdateManager and accept the updates (this is not the same as an upgrade to a later version of Ubuntu, which you should avoid doing unless you deliberately want that). 1) Multimedia – Linux native codecs To get pretty well all of the multimedia codecs the easy way, ensure the machine is connected to the internet and use the facility Add/Remove applications If the list is out of date, accept a refresh, and more recent information will be downloaded. Then use Applications>Add/Remove Ensure that 'All' is selected, and Click the choices to select 'All Available Applications' from the list. Then into the 'Search' space type gstreamer After a short time, the search results will display a number of gstreamer entries and in addition the item 'Ubuntu restricted extras'. For each of these in turn, including the 'Ubuntu restricted extras', click the check box so that a tick is shown. As you do this you will also be asked to confirm what you want and that you do not live in a country where such codecs are not allowed (such as USA). Note that in some versions of Ubuntu, for example, 9.04, the [gstreamer fluendo MPEG2 demuxing plugin] is not required and will conflict with other installed software. If so, you will see an error warning message, so in this case, there is no need for this item. When your choices are all checked and accepted, click the 'Apply' button and they will be downloaded and installed. You will now have installed most of the multimedia codecs. 2) Further actions: Playing Encrypted DVDs The several actions above will be capable of installing most multimedia codecs. However, to play encrypted DVDs (some commercial DVDs), the libdvdcss2 package is also an essential requirement. libdvdcss2 is a simple library designed for accessing DVDs like a block device without having to use decryption. This can be installed easily after the medibuntu repository has been enabled for your machine, please see below. 3) Playing some non-native formats Some media formats do not have native Linux facilities. In such cases it is possible to make use of binary Windows and other codecs through a 'wrapper', bundled as the 'w32codecs', for playback of these media formats. This can be installed easily after the medibuntu repository has been enabled for your machine, please see below. There are various ways of installing these additional packages, although the exact details depend upon which type of computer you have and which version of Ubuntu you use (Note 1). 4) The medibuntu repository If your computer is configured to make use of the special software repository for Multimedia, Entertainment & Distractions In Ubuntu (medibuntu), then subsequent actions, including security updates, can be handled conveniently. Unfortunately for the beginner, the configuration to include a new software repository can seem a bit demanding at first. The following actions are closely based on information at https://help.ubuntu.com/community/Medibuntu An overview of actions is: - Get the sources list and keyring - Then get specific information for your Ubuntu version - Then, add the GPG Key (to help ensure you only use the repository you are expecting). The detailed actions for these three stages are best followed by using the medibuntu link https://help.ubuntu.com/community/Medibuntu (please note the leading upper case in the word Medibuntu here) On that page please see: 'Adding the Repositories' This technique makes use of a Terminal, and copy and paste. If it seems complicated at first, have a look again at the overview of actions listed above, to help see what is being done. How to get a 'Terminal'? Applications>Accessories>Terminal It is a powerful way of doing things fast. It is certainly much more powerful than it first appears, so do not rush with any typing or commands. Take your time. For example, the first action is to get the sources list and keyring, appropriate for 'Any Ubuntu Release and keyring'. Carefully highlight the appropriate block of text in the medibuntu page, edit>copy, then into the Terminal, use edit>paste into the terminal. When you hit the Return key your password will be needed, and actions begin. Wait until all downloads are completed and you see a normal prompt again. Complete the subsequent two actions listed in the overview above, specific information for your Ubuntu version, and then the GPG key, in a similar way. Please refer to the medibuntu page for more detailed information. When these actions are completed, medibuntu repository is available in your Ubuntu. Well Done! You can verify your success by looking at System>Administration>Software Sources and the tab Third Party Software and you should see medibuntu packages free and non free as being entered and ticked (enabled). Installing the packages: libdvdcss2 and w32codecs As will be seen in the Medibuntu page referenced above, to play encrypted DVDs it is necessary to use libdvdcss2. Because in the preceding actions in this information sheet, the entire Medibuntu repository has already been made available, then it is now only necessary to call for the particular package to be installed, so, we follow the Medibuntu page's information to install libdvdcss2. Use a terminal and carefully enter sudo apt-get install libdvdcss2 For non native formats for i386 (32 bit) machines, the w32codecs is needed. To install this, use a terminal and carefully enter sudo apt-get install w32codecs For amd64 (64 bit) and PPC machines please use the appropriate package names as detailed in the Medibuntu pages.
