|
* To aid debugging applications one can use this method to write out the whole

* network of gstreamer elements that form the pipeline into an dot file.
|
|
* This file can be processed with graphviz to get an image, like this:
|
|
* <informalexample><programlisting>
|
|
* dot -Tpng -oimage.png graph_lowlevel.dot
|
|
* </programlisting></informalexample>
|
|
* There is also a utility called xdot which allows you to view the dot file
|
|
* directly without converting it first.
|
|
*
|
|
* The macro is only active if gstreamer is configured with
|
|
* "--gst-enable-gst-debug" and the environment variable
|
