The occam-π language provides many novel features for concurrent software development. This paper describes a video processing framework that explores the use of these features for multimedia applications. Processes are used to encapsulate operations on video and audio streams; mobile data types are used to transfer data between them efficiently, and mobile channels allow the process network to be dynamically reconfigured at runtime. We present demonstration applications including an interactive video player. Preliminary benchmarks show that the framework has comparable overhead to multimedia systems programmed using traditional methods.
