GStreamer

GStreamer is a streaming media framework that allows the construction of graphs of elements which operate on media data. Applications using this library can do anything from real-time sound processing over playing video to capturing audio, video, and even other types of media data. Its architecture allows for adding new data types or processing capabilities simply by installing new plug-ins. GStreamer is the core module, containing libraries, headers, the basic object hierarchy, and a set of media-agnostic core elements.
