i was trying to get live video from ar drone 2 using the new method
mentioned in ar drone 2 getting started page on wiki but the fps is too low
and i have a delay of two seconds at best!
i switched to the old way mentioned there on wiki page. the gstreamer is
uploaded and the fps is now okay but the resolution is too low. when i
change the gst-launch command height and width for better resolution the
stream doesn't show up on my laptop. 
here is the command i telnet on the device:
/opt/arm/gst/bin/gst-launch v4l2src device=/dev/video1 ! videorate !
'video/x-raw-yuv,framerate=30/1' ! videoscale ! video/x-raw-yuv, width=640,
height=480 ! dspmp4venc ! rtpmp4vpay config-interval=2 ! udpsink
host= port=5000 > /dev/null 2>&1 &

here is the command i run on my laptop:

gst-launch-0.10 udpsrc uri=udp://  caps = 'application/x-rtp,
media=(string)video, clock-rate=(int)90000, encoding-name=(string)MP4V-ES,
payload=(int)96' ! rtpmp4vdepay ! ffdec_mpeg4 ! ffmpegcolorspace !

as mentioned on wiki page.

any thoughts on how can i get a better live video frome ar drone 2 while
running paparazzi autopilot on it??
i want to use the video feed for image processing on ground station.
