> By now, you should be able to create basic filter elements that can
receive and send data. This is the simple model that <SPAN
CLASS="application"
>GStreamer</SPAN
> stands
for. But <SPAN
CLASS="application"
>GStreamer</SPAN
> can do much more than only this! In this chapter,
various advanced topics will be discussed, such as scheduling, special
pad types, clocking, events, interfaces, tagging and more. These topics
are the sugar that makes <SPAN
CLASS="application"
>GStreamer</SPAN
> so easy to use for applications.
