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. This package is part of the 'base' plugins for GStreamer. It provides the alsa plugin, which allows playback and recording of sound through the Advanced Linux Sound Architecture (ALSA) audio libraries.
