Syphon is a new open source framework for Mac OS X 10.6 that allows users to share frames of video across applications. Sharing happens on the graphics card, and thus is hardware accelerated and very fast. Sharing of HD frames, at full 60 frames per second is more than possible.

Syphon is "opt-in", meaning applications can natively support Syphon frame sharing by linking to our framework and writing some additional code, or by supporting an existing plugin architecture that Syphon has implementations for, such as Quartz Composer, Free Frame GL, or Max5 externals, etc.

Sharing requires no additional applications, and an application can publish multiple distinct frame sources, and receive multiple distinct frames.
