 # the last message dialog: that's our GStreamer graph processing the
 # audio and video from IP Webcam.
 #
+# ALSO IMPORTANT: if you have issues with this script, make sure that
+# v4l2loopback works properly by running these commands. You'll first
+# need to install mplayer and ensure that your user can write to
+# /dev/video*), and then run these commands on one tab:
+#
+#  sudo modprobe -r v4l2loopback
+#  ls /dev/video*
+#  (Note down the devices available.)
+#  sudo modprobe v4l2loopback
+#  ls /dev/video*
+#  (Note down the new devices: let X be the number of the first new device.)
+#  gst-launch videotestsrc ! v4l2sink device=/dev/videoX
+#
+# Now go to another tab and use mplayer to play it back:
+#
+#  mplayer -tv device=/dev/videoX tv://
+#
+# You should be able to see the GStreamer test video source, which is
+# like a TV test card. Otherwise, there's an issue in your v4l2loopback
+# installation that you should address before using this script.
+#
 # Last tested with:
 # - souphttpsrc version 0.10.31

-# - v4l2loopback version 0.5.0
+# - v4l2loopback version 0.7.0
