**5. [DS5.0GA\_App] Generate GStreamer Pipeline Graph**  
Use one of below method according to your application type to generate the GST pipeline graph.

```
4.1 deepstream-app
 run "export GST_DEBUG_DUMP_DOT_DIR=/tmp/" before deepstream-app command, e.g.
 $ sudo apt-get install graphviz
 $ export GST_DEBUG_DUMP_DOT_DIR=/tmp/
 $ deepstream-app -c deepstream_app_config_yoloV2.txt
 $ cd /tmp/
 $ dot -Tpng 0.03.47.898178403-ds-app-playing.dot >~/0.03.47.898178403-ds-app-playing.png // png file includes the graph

4.2 gstreamer command line
for exmaple,
  $ run "export GST_DEBUG_DUMP_DOT_DIR=/tmp/" before deepstream-app command, e.g.
  $ sudo apt-get install graphviz
  $ export GST_DEBUG_DUMP_DOT_DIR=/tmp/
  $ gst-launch-1.0 ....
  $ cd /tmp/
  $ dot -Tpng 0.03.47.898178403-ds-app-playing.dot >~/0.03.47.898178403-ds-app-playing.png // png file includes the graph

 4.3 DeepStream application
  for exmaple
  4.3.1 add "g_setenv("GST_DEBUG_DUMP_DOT_DIR", "/tmp", TRUE);" before gst_init()
  4.3.2 add "GST_DEBUG_BIN_TO_DOT_FILE_WITH_TS(GST_BIN(gst_objs.pipeline), GST_DEBUG_GRAPH_SHOW_ALL, "demo-app-pipeline");" at the point where want to export the dot file, e.g. when switching to PLAYING
   BTW, need to include header file - #include <gio/gio.h>

 4.4 Python DeepStream
