66 * @file_name: output base filename (e.g. "myplayer")
68 * To aid debugging applications one can use this method to write out the whole
69 * network of gstreamer elements that form the pipeline into an dot file.
70 * This file can be processed with graphviz to get an image.
71 * <informalexample><programlisting>
72 * dot -Tpng -oimage.png graph_lowlevel.dot

75 * The macro is only active if gstreamer is configured with
76 * "--gst-enable-gst-debug" and the environment variable
77 * GST_DEBUG_DUMP_DOT_DIR is set to a basepath (e.g. /tmp).
