+# ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+# TODO list:
+# ----------
+# - Implement a method to switch to webcam feed if Elphel cam feed is lost
+# --> Use ping by opening Telnet connexion every 2 seconds (if it fails, then switch to webcam)
+# --> Has to be threaded
+# - Add a checkbox to enable/disable options (storing/streaming - storing only - stream only - etc...)
+# - Add a function to get the ip address of the camera automatically (see github.com/paulmilliken)
+# - Create a module for the network configuration (fan/cpu, ifconfig, stream server,etc)
+# --> Taken care in FAI building
+# - Generate a log file during runtime. (e.g. this will let you know if the network configuration
+# and the pipeline construction went well (or not))
+# - Add an input source choice for the user (camera on IP or webcam)
+# - Add a time counter
+# --> Has to be threaded
+# - Add a 'CPU load' widget
+# - Add the FSF logo (need to do some pixel art) as an application icon
+# - Add the FSF logo inside the streamer use the 'textoverlay' method in ElementFactory.make()
+# ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
