Who is Oscar?

Oscar is an OSC-to-Flash bridge, much like flosc.

Its purpose is to make Flash based applicationsĀ  communicate with other OSC (and TUIO) enabled devices and applications in the same network.

Oscar is made up with Cocoa and Python (you can easily access the code inside the application package).

Some features:

- You can filter messages, reducing network overload (this is particularly useful when using a minimal TUIO setup, thus not needing the source tag, for instance).

- The interface keeps track of the network activity on both sides, and shows the number of Flash clients connected (either on main window or as a badge on the application icon on the Dock).

- The app updates itself automatically like many other famous apps (thanks to the Sparkle framework).

- You can choose whether to filter or not general OSC tags (by specifying them in the “OSC filtering” preference panel) and/or specific TUIO messages (by specifying them in the “TUIO filtering” preference panel).

- You can choose to start the bridge automatically at application launch (useful for automated installations where oscar could even be added to startup items), or start and stop the server manually.

Technically speaking, Oscar receives data from an UDP socket (which is the OSC/TUIO transmission protocol), translates it to XML-based messages that Flash can understand and forwards them via a TCP socket to all the Flash app clients connected (both on the local machine and/or on the network).

Software/hardware requirements

- Mac Os X 10.5 or later, on Intel or PowerPC processors (the application is Universal Binary).

To-do list

- Two-way communication (Flash-to-OSC).
