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.

A plugin for Quartz Composer to misrepresent pixel-buffer data on the GPU.
