Removal of Ogg Vorbis and Theora from HTML5

In a previous post, we were enthusiastic about the new developments of html5 that would include the video tag and its implementation in the royalty-free format ogg/vorbis. But:

“As some of you may be aware, the WHATWG has dropped the recommendation for Theora and Vorbis in the video/audio section of the HTML 5 specification. Many believe it’s due to pressure from Nokia and Apple and, while that may be correct, it’s only the tip of the iceberg.”

Read the article on spreadopensourcemedia that sums up quite well the whole issue.

After hearing enthusiastic reports of colleagues who saw a demonstration of Toonloop during the Libre Graphics Meeting, I was curious to find out more. I installed it, worked a bit with it, and I have to say: not often am I thrilled by new software for video on GNU-Linux, but this time: Ooh yes!
Toonloop could easily become my favorite tool for capturing images.

Zittrain: Here Comes Everybody


An ogg/vorbis bootleg recording of Jonathan Zittrain’s talk Here Comes Everybody. In this entertaining yet serious speech Zittrain addresses social political aspects of video on the web, the need to consider local mesh network strategies, the power of ISP’s. Where is ‘here’ in the cloud of the web? What is the positive and negative potential of mass scale availability of workforce on the web?

Jonathan Zittrain is co-director and co-founder of Harvard’s Berkman Center for Internet and Society and a professor at Harvard Law School. Among his areas of expertise are cyberlaw, security, and copyright law. His book The Future of the Internet—And How To Stop It is about generative technology like the internet and how it promotes innovation and disruption. As controlled devices like iPods and Tivos grow in popularity, we face worrisome consequences for the net’s future potential for user participation.
