“In the Linux community there are a lot of projects getting
started everyday. Some die quickly, others hang on for a little
while before dwindling away. Then there are a few which seem to

that they have been the target of some hard and talented work for a
long time by a single hacker or just a small group of hackers,

One of the projects which recently seemed to burst onto the Linux

interview with project founder Erik Walthinsen we will discover
that there was nothing overnight about GStreamer’s recent rise to
fame at all, rather the hard work off a dedicated team. This hard
work has really paid of with Erik getting hired by embedded Linux
distribution company RidgeRun, Inc. to work fulltime on
