Via the FSF: "The first round of videos from LibrePlanet 2013 is now available for streaming and downloading. LibrePlanet is an annual conference sponsored and organized by the Free Software Foundation, with LibrePlanet 2013 being the best one yet. ... This year we set out to make sure LibrePlanet featured fully functioning live video streaming using only free software, and it was a great success. The videos are now available for viewing in VP8/Vorbis, both free media formats, and are hosted on an instance of GNU MediaGoblin, the social media sharing platform which many of you helped support."
The rest of the videos should trickle onto their Mediagoblin instance over the next weeks. All of the videos are freely licensed (looks like a mixture of CC BY and BY-SA 3.0).
