## GStreamer Core Library

GStreamer - Media library supporting arbitrary formats and filter graphs.
GstBin - Base class for elements that contain other elements

GstElementFactory - Create GstElements from a factory
GstError - Categorized error messages
GstEvent - Structure describing events that are passed up and down a pipeline
GstFilter - Take data in and spit data out
GstFormat - Dynamically register new formats
GstGhostPad - Pseudo link pads
GstImplementsInterface - Core interface implemented by GstElements that allows runtime querying of interface availabillity
GstIndex - Generate indexes on objects
GstIndexFactory - Create GstIndexes from a factory
GstInfo - Debugging and logging

GstPad - Object contained by elements that allows links to other elements
GstPadTemplate - Describe the media type of a pad.
GstParse - get a pipeline from a text pipeline description
GstPipeline - Top-level bin with scheduling and pipeline management functionality.
GstPlugin - Container for features loaded from a shared object module
GstPluginFeature - Base class for contents of a GstPlugin
GstProbe - Receive callbacks of data passing
GstQuery - Dynamically register new query types
GstQueue - Simple asynchronous data queue.
GstRealPad - Real link pads
GstRegistry - Abstract base class for management of GstPlugin objects.
GstRegistryPool - Management of a group of GstRegistry objects
GstScheduler - Abstract class for objects that manage the scheduling of groups of elements
GstSchedulerFactory - Create schedulers from a factory
GstStructure - Generic structure containing fields of names and values
GstSystemClock - Default clock that uses the current system time
GstTagList -
GstTagSetter - Element interface that allows setting and retrieval of media metadata
GstThread - A GstBin that executes automatically using a separate thread
GstTypeFindElement - typefinding subsystem
GstTypeFindFactory - information about registered typefind functions
GstTypes - various global enums and constants
GstUriHandler - Plugin feature that handles URI types
GstURIType - describes URI types
GstUtils - various utility functions
GstValue - GValue implementations specific to GStreamer
GstVersion - GStreamer version macros.
GstXML - XML save/restore operations of pipelines

libgstreamer-0.8.so provides all the core GStreamer services, including initialization, plugin management and types, as well as the object hierarchy that defines elements and bins, along with some more specialized elements.
