hi, i just tested video streaming from the drone, using [1], [2]

 1. cd sw/ext
 2. git clone https://github.com/tudelft/ardrone2_vision.git
 3. cd ardrone2_vision
 4. sudo apt-get install scratchbox2
 4a. make
 4b. make pulls ardrone2_gstreamer submodule, then fails, ignore
 5. vim ardrone2_gstreamer/Makefile
 6. adjust path to arm-linux-gnueabi- cross compiler
 7. make install
 8. fails with configure error for libtool, ignore
 9. make drone
 10. uploads stuff
 11. telnet drone
 12. execute the /opt/arm/gst/... commandline from [2]3)
 13. execute the first command from [2]4), gst-launch playbin ...

writing this, i now realize that the ardrone2_vision module
 - contains actual gst plugin demos doing useful stuff with the vision
   input
 - ardrone2_gstreamer just contains the drone-side gstreamer stuff for
   capturing and downstreaming

experienced something similar. when executing the flight plan with
joystick and input2ivy connected and running, the throttle will be taken
from the joystick while all the lateral commands come from the
flightplan. i guess its because we're in AUTO1, switching to AUTO2
should change this?

bst, opt
