> In these chapters, we will discuss the basic concepts of <SPAN

>GStreamer</SPAN
>
and the most-used objects, such as elements, pads and buffers. We
will use a visual representation of these objects so that we can
visualize the more complex pipelines you will learn to build later
on. You will get a first glance at the <SPAN
CLASS="application"
>GStreamer</SPAN
> API, which should
be enough for building elementary applications. Later on in this
part, you will also learn to build a basic command-line application.
</P
><P
> Note that this part will give a look into the low-level API and
concepts of <SPAN
CLASS="application"
>GStreamer</SPAN
>. Once you're going to build applications,
you might want to use higher-level APIs. Those will be discussed
later on in this manual.
