GStreamer is a library that allows the construction of graphs of 
media-handling components, ranging from simple Ogg/Vorbis playback 
to complex audio (mixing) and video (non-linear editing) processing.
Applications can take advantage of advances in codec and filter 
technology transparently. Developers can add new codecs and 
filters by writing a simple plugin with a clean, generic interface.

GStreamer is released under the LGPL.
