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

|
|
* This file can be processed with graphviz to get an image, like this:
|
|
*
|
|
* ``` shell
|
|
* dot -Tpng -oimage.png graph_lowlevel.dot
|
|
* ```
|
|
*
|
|
* 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 the environment variable `GST_DEBUG_DUMP_DOT_DIR`
|
|
* is set to a basepath (e.g. `/tmp`), and the GStreamer debugging subsystem is
|
|
* enabled (i.e., no use of `./configure --disable-gst-debug`)
