-GStreamer concepts are as follows:<ul>
-<li><p><b>Element</b> </p><p>An element is an object that performs some action
-on a multimedia stream. Examples of such actions are reading a file, decoding
-or encoding data and capturing data from a hardware device.</p></li>
-<li><p><b>Bin</b></p><p>A bin is a subclass of element. A bin acts as a container
-for other elements, so multiple elements combine into one logical unit.</p></li>
-<li><p><b>Pipeline</b></p><p>A pipeline is a set of data processing elements
-connected in series, so the output from one element is the input for the next
-element.</p><p>In GStreamer the pipeline is a specialized bin subclass that
-provides execution of all contained elements. Normally, applications create
-one pipeline that will manage all the elements contained within it.</p></li>
-</ul></p><p><b>Note:</b> Elements can be added to and removed from pipelines
-based on the use-case being handled. For example a use-case such as playing
-an <i>MP3</i> file using GStreamer.</p><p>An element can provide a number
-of pads, which can be either source or sink pads. A pad is a plug or port
-on an element to link with other elements. The pads are responsible for data
-flow between the elements. Source pads supply data, and sink pads consume
-data. Basically, pads are used to negotiate compatibility and allow data flow
-between elements.</p><p>An element can be in one of four different states
-during the application request: <ul>
-<li><p>Null</p></li>
-<li><p> Ready</p></li>
-<li><p>Pause</p></li>
-<li><p>Play</p></li>
-</ul> In the <i>Null</i> and<i> Ready</i> states, the element is not processing
-any data. The processing of data happens only in the <i>Play</i> state. The <i>Pause</i> state
-is used to fill all connected elements in the data pipeline so the <i>Play</i> state
-change happens quickly.</p><p>GStreamer also provides higher level utilities
-and components to detect automatically the media type of an application, and
-to create the best possible pipeline for a use-case. This process is called
-auto plugging.</p></section>
