Abstract:

This is a tutorial for writing a GStreamer element in Python. It includes a sample problem, skeleton code, a complete code walkthrough, and a set of 'bonus' projects designed to teach analysts more about stream-based programming and the mechanics of GStreamer.

This was presented at the "Gravitational Waves with GStreamer" workshop on November 8, 2010, at the Canadian Institute for Theoretical Astrophysics.
