Hey good work – thanks for this. I’ve been playing with the Canon SDK a bit myself, but not got anything to the release-worthy stage, so well done.
A few points
– It does work with a 7D, yay!
– Could you use the Syphon icon and not Syphon Recorder’s icon in the app icon? The icon is available at http://syphon-framework.googlecode.com/svn/trunk/Syphon%20Icon.icns
– The app crashes when I quit it with a camera attached
– There’s nothing about Syphon that means you can’t hide or minimise an app and keep a server running. This is probably a limitation of OpenFrameworks – it should be something you can work around.
