Update (2009-05-20): 1080p and standard definition videos of the talk in Theora/Vorbis are now available. See below for details.
I presented a talk entitled “DVDs, MP3s, YouTube, and other hindrances to free software” (abstract) today at FOSSLC’s Summercamp 2009 (#fosslcSC09) in Ottawa. Here are the slides:
Here are the videos (all videos are Copyright © 2009 FOSSLC, licensed under Creative Commons Attribution-Share Alike 2.5 Canada):
Please feel free to re-encode or transform the above videos in whichever ways you wish. Besides syncing the videos with slides in a standards-based way, you may want to trim the videos to the start and end of the talk or re-encode them to a different resolution.
If you would like the source files for the HD version, which are in MPEG-2, please let me know. They are quite large (about 8 GiB in total) so I haven’t posted them here.
- The “Why do we care?” slide should have mentioned the Gdium Liberty, a netbook that uses a MIPS processor, as an example of a product made by a small company, which does not have the resources to license Flash or codecs. Reducing people’s reliance on Flash and royalty-requiring codecs will allow many more products like this to enter the market. As it is, there are very few small companies making innovative new computers.
- The “What can we do about patented codecs?” and “What can we do about TPMs?” slides should have mentioned alternative music stores like Jamendo, which hosts music freely-licensed by the authors and offers it for download without DRM and in Ogg Vorbis format.
- The “What can we do about proprietary formats?” slide should have mentioned Free Youtube! and Free Slideshare!, which allow you to view YouTube and SlideShare without using a Flash player.
I have created Ogg Theora/Vorbis and XviD/MP3 versions of the excellent documentary RiP: A Remix Manifesto. You can find them at the following locations (Update – 2009-05-10: You can pay what you want for zipped versions of these, which are about 1% smaller, at http://www.ripremix.com/getdownloads/):
I encourage you to support the creator by paying what you can at one of these pages:
I recommend the Theora/Vorbis version because it is higher-quality (853×480 pixels) and because Theora and Vorbis are royalty-free codecs (see The codec dilemma for why this is important). I also provided an XviD/MP3 version since many DVD players support this format.
If you want to remix the documentary, check out Open Source Cinema, where you can upload your own modifications to it. The videos there and the downloads listed above are licensed under the Creative Commons Attribution-Noncommercial 3.0 Unported license.
This is a response to John Dowdell’s Put down the Flavorade and slowly back away…. post, which is itself a reply to Tristan Nitot’s Making video a first class citizen of the Web. Here it is, starting with a quote from John Dowdell’s post:

You may have heard that Moonlight, the free software Silverlight plugin for GNU/Linux distributions, allows users to view certain audio and video encoded with Microsoft codecs. What may be confusing, though, is how you can do this if Moonlight is free software since the Microsoft codecs are patented (see “The codec dilemma” for details). I dug into this a bit and here’s what I found:

I was recently asked about how free the Vorbis and Theora codecs are, particularly with respect to gratis versus libre. The answer to this question is more complicated than it looks and requires a deeper look into the difference between a specification and an implementation.

Every day millions of videos are watched on video hosting sites like YouTube. Most viewers don’t think of how the videos are stored or how they get displayed on one’s computer. But these are critical questions in determining who is able to watch online videos and how much money they need to pay to do it, even on free hosting sites. Let me start by explaining what a “codec” is.

In my previous post (“Why I haven’t installed a Flash player“), I tried to convince people why supporting Adobe Flash by installing a player was a bad idea. My hope was that efforts like mine would reduce the number of sites using Flash and eventually eliminate non-standard technologies like Flash from the web. Recent events made me realize why such efforts to get rid of Flash will pale in comparison to the natural phenomena that are already working together to seal Flash’s fate.

You may have heard about Google’s new voice and video chat plugin for Gmail, which lets you use voice and video through the Gmail web interface. You may have also heard that the plugin is standalone (does not require other plugins) or an alternative to using Flash for voice and video chat solutions. Like many, I thought that because Gmail voice and video chat was a plugin, it did not require Flash at all. However, further research showed that this was not the case.

Along with their commitment to free and open source software in government, the Green Party of Canada takes an excellent stance on copyright reform. According to a response from Green Party candidate Glenn Hubbers and the Green Party response to the Canadian Conference of the Arts questionnaire, the Green Party will:
- Remove the Levy on Blank Audio Recording Media and replace it with private copying exemptions;
- Introduce a formal notice-and-notice mechanism for dealing with copyright infringement online, thereby affirming common carrier status for Internet Service Providers (ISPs);
- Renounce the Crown Copyright applied to all government produced documents, thereby immediately releasing them into the public domain;
It seems almost coincidental that the Green Party’s stated goals so closely match my own. Let me elaborate on why these reforms are necessary.

A recent article on Slashdot, Canonical Offers Sale of Proprietary Codecs for Ubuntu, opens with the following line:
Playing DVDs on Linux that required proprietary codecs has been a source of much pain.
This statement is misleading. The primary reason that DVDs cannot be played by default under most distributions is CSS. To play a DVD with CSS, you need a licensed player that has a key to unlock the CSS or you need to circumvent the CSS. In both cases, the openness of free software is at odds with the desires of the motion picture industry.
