GStreamer Core Elements

GstFakeSrc - Push empty (no data) buffers around
GstFakeSink - black hole for data
GstFileSrc - read from arbitrary point in a file
GstFileSink - write stream to a file

libgstelements.so provide some basic elements like a file source and sink. The use of these elements is strictly though the g_object_get() and g_object_set() functions and the GStreamer Core Library functions.
