You can link the different pads of elements together so that the elements
|
|
form a chain.

By linking these three elements, we have created a very simple
|
|
chain. The effect of this will be that the output of the source element
|
|
(element1) will be used as input for the filter element (element2). The
|
|
filter element will do something with the data and send the result to
|
|
the final sink element (element3).

Imagine the above graph as a simple MPEG audio decoder. The source
|
|
element is a disk source, the filter element is the MPEG decoder and
|
|
the sink element is your audiocard. We will use this simple graph to
|
|
construct an MPEG player later in this manual.
