<<Include(Tag/Deletion)>> This page is for discussion about the RestrictedFormats wiki.
2008-08-03 It seems like http://ubuntuforums.org/showthread.php?t=766683 is the most authoritative link on this subject these days, but I like the tone of this document better. Hopefully someone could consider combining the best elements of that guide here? In the mean time I've added a link to it... furicle
2007-07-17 I can understand why removing the alternate players will clean up the page and reduce confusion, but the original reason I documented totem-xine, mplayer and xine as alternate players was totem-gstreamer's inadequacy as a movie player. Unless the gstreamer backend has substantially improved, I'd vote for keeping at least totem-xine documented. Additionally, the simple link to MultiMedia won't be sufficient, since it points back to RestrictedFormats for installation instructions. As a short term solution, reverting the change would make sense until discussion about how to split out the non-official players is done. RichRudnick
2007-06-20 If you feel something is missing or needs to be corrected, feel free to edit the wiki. 'gstreamer0.10-plugins-bad' is not included in ubuntu-restricted-extras, so it should get included.
2007-06-20 I've recently installed Feisty to a Dell Inspiron 6400/E1505 laptop, and could not get DVDs to play. I followed the instructions on 'RestrictedFormats' and still no DVD playback. I then attempted to play a .mov file (I think, not sure), which prompted installation of 'gstreamer0.10-plugins-bad'. DVD playback then worked. The instructions for 7.04 in this article do not mention this package, whereas 6.10 and 6.04 instructions explicitly do. Should the 7.04 instructions in this article be updated to include installation of this missing package? David_1cog
2007-04-24 Hi Andres, thanks for your comments. While the packages in restricted extras do take up space if users don't need them all, this is still the preferred method for most users:
- Restricted extras is one package, as opposed to multiple packages one must consider whether to install
- More users wish to use multiple common retricted formats, than those who may wish to use some and not others
- Ubuntu documentation should provide instructions that support the use of these formats on standard media players before alternate media players, simply because they defaults an sould this work with the minimum of hassle.
The detailed xine information is useful, but it takes second priority to making sure all common file formats work with Ubuntu's default apps. MikeMacCana
2007-04-24 To MikeMacCana, I'm placing the xine section back at the top. ubuntu-restricted-extras doesn't solve everyone's restricted format problem. Actually, there are some people that don't even care for all the packages in this metapackage. Why tell people to automatically install ubuntu-restricted-extras? Things can get done a lot faster by just installing what you need for a particular format/formats. Not to mention that they won't have any of the extra bloat, such as xine users who will have no use for gstreamer, or gstreamer users who have no use for xine. --AndresMejia
2007-04-20 I'm starting changes to this page so that people will avoid having to install ubuntu-restricted-extras and thus installing stuff that they probably don't need or ever use. The last section of this page will include the information for the ubuntu-restricted-extras. --AndresMejia

The discussion of the "Restricted Formats" here is more balanced than many others. I have read much needless hysteria about the "Restricted Formats." However, the following should be noted in any discussion of potential copyright/patent infringement on the part of users, so that users may make balanced, informed decisions:
The "restrictions" being discussed apply to distributors of the software, not the users. The vast majority of computers manufactured in the world came with an OEM license to Microsoft Windows. The license is transferred if and when the CPU is transferred (i.e., the license follows the CPU). Consequently, computers that originally had Windows 98 2nd Ed. and greater already come with a license. That license permits the owners' use of Microsoft technologies available to the licensed version of Windows. The codecs, DVD decoders, and other "restricted" technologies are available on Microsoft Media Player 9 and above, which Microsoft distributes for free to holders of licenses to Windows 98 2d Ed and later. Therefore, you may legally load Windows codecs and decoders (including for DVDs) on your computer if it has a license to Windows 98 Second Edition, Windows 2000, Windows Millennium Edition, Windows XP, or MS Vista. (The short version: The odds are virtually nil of Microsoft winning a lawsuit against someone who has a computer which has ever had a legal copy of Windows in the last 9 years.)
With respect to DVD and the CSS: If you purchased a DVD produced by the studio or its licensee, the studio has given you a license to sell, rent, or use the DVD, usually for private home use. As long as you are using the DVD under the terms described on or in the DVD and are not making a copy or reproduction of the DVD, you have no reason to fear. Having a descrambler on your computer is not itself illegal if you are using it for the intended purposes (i.e., to watch the DVD). After all, the signal has to get descrambled for you to watch the movie.
If you are selling a computer with a DVD drive, you also need not fear. The drive has on it the DVD logo from the DVD because the maker of the DVD drive has a license from the DVD Format/Logo Licensing Corporation. That license means that the player/drive is in full compliance with the DVD Format Book. Assuming the manufacturer didn't bootleg the logo, you can install and resell the device in confidence. That's why the logo licensing procedure was developed.
Now, if you decided to reengineer CD drives (or any drive without the DVD logo) so it could descramble and copy DVDs, and you were selling them or using them for non-private use, you'd probably have a problem. But if you're going to go to that trouble, it'd be cheaper and easier just to get the license.

Thank you. This is good to know.

2007-03-29 I think we should give instructions on how to install external codecs using UbuntuHelp:Medibuntu. Therefore I'm going to make some modifications to the RestrictedFormats page to do just that. The windows codecs|RestrictedFormats/WindowsCodecs|windows codecs page is kind of outdated and a bit misleading as well (w32codecs don't contain just Windows codecs). --AndresMejia
2007-02-08 Why have the Kubuntu-specific packages been left out of the installation instructions? Installing gstreamer plugins is mostly useless there, and more than libxine-extracodecs are needed for various applications. This has created a some confusion to new users. --ClayWeber
2007-02-08 Screenshots serve the purpose of letting people know that Ubuntu can actually do the things the page says - i.e., that this work has results, and that Ubuntu can play common, real videos, not just videos of Nelson Mandela. Most human-readable computer documentation includes screenshots of results of end-user work, including official Ubuntu documentation. They also keep the page from being a large mass of text. Re-added. --MikeMacCana
2007-01-15: The "The (K)Ubuntu Media Players" and "Alternative Media Players" sections seem to just repeat the information found at MultimediaApplications. Why not just link there instead of duplicating the information? --JasonRibeiro Agreed. --MikeMacCana
2007-01-07: totem-xine *does* play DVDs just fine. There is no need for ogle and gxine to be listed under codec installation. They should be listed under Alternative Players where they belong. Does anyone object to this? - The default totem backend is totem-gstreamer, and the MakeStuffWorkInAHurry line does not include totem-xine. Just so you know. And recommending that users install totem-xine is maybe not a good idea because of the all-my-videos-are-too-white bug that many people are seeing (screenshot), which seems to affect xine and not gstreamer.
2006-12-21: MikeMaccana, I am going to temporarily revert all your recent changes because the current state of the page will result in an error for anyone who follows the instructions. w32codecs and libdvdcss2 are not in the ubuntu archive, they are 3rd-party packages, so the single line solution you recommend simply doesn't work. I am not objecting to your changes in general, just reverting for now to get the page back in a usable state. Before you edit again, please make sure that what you write will actually work on a Ubuntu system. --JonasJørgensen
