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

By connecting these three elements, we have created a very simple pipeline. 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.
