Hap is a codec for fast video playback I wrote for Vidvox. Everything is open-source, including the codec and example code to get it running in third-party applications.

There’s an article and installer over on their site.

Sampler in use in Australian Dance Theatre's Proximity

Sampler plugin for Quartz Composer. Loop live video, MIDI data, or any other values. Thanks to Thomas Pachoud and Australian Dance Theatre for supporting work on this, and to Joris/goto10 for the original idea.

In 2009 vade and I developed the VVFFGL framework which provides FreeFrame GL support for VDMX. Vidvox have open-sourced our work: as well as the framework there’s a Quartz Composer plugin for running FreeFrame GL (and older FreeFrame 1.0) plugins in Quartz Composer.

vade and I have just released Syphon for realtime video sharing between apps. Read about it at createdigitalmotion. Udart at Obscura did a nice post about Syphon too.

I won’t make it to GLI.TC/H in person, but I’m there in spirit in Bob Weisz & Paul Korz’s installation at the gallery, and I’ll be making a long-armed remote-control appearance at vade’s Realtime Glitching workshop on the Saturday.

Addendum: Nice writeup by Tom McCormack at http://rhizome.org/editorial/3819
