SIP enabled RAT/VIC

Google Summer of Code 2008 ideas

Mentors: Piers O'Hanlon (UCL) (p.ohanlon at gmail.com),
Colin Perkins (Glasgow University, IETF AVT WG Chair) (csperkins at gmail.com)

Background

The cross-platform (Linux, OSX, Windows) tools Robust Audio Tool (RAT), Video Tool (VIC), and UCL Common multimedia library are widely deployed in various Operating systems (e.g. Ubuntu Linux and FreeBSD). They also underpin the globally deployed AccessGrid advanced collaborative environment.

Currently the OMII-UK AVATS project provides for enhanced stability and baseline support (though new features as suggested below would not be covered): http://www.cs.ucl.ac.uk/research/avats/.

The media tool's development Trac and Subversion site: http://mediatools.cs.ucl.ac.uk/.

Project Goals

Integrate support for Session Initiation Protocol (SIP) into Robust Audio Tool (RAT) and/or Video Tool (VIC) - this would provide for an advanced open source SIP enabled media tool with some of the most advanced features (e.g. redundant layered audio), and the widest codec selection available. This could be achieved using any of the open source SIP libraries (e.g. OPAL, PJSIP, SIPFoundry, oSIP, etc).

Project Requirements

In order to be able to successfully be able to complete this project the student should be able to program in C/C++/Tcl/Tk.
