communiquer avec une camera ip a partire de l'internet

Question

Bonjour tout le monde,
je veux communiquer avec une camera ip a partire de l'internet , et faire visualiser le flux video .
url de camera : [216.62.222.100 216.62.222.100]
pouvez vous m'aider avec un code java(netbeans)? 
et merci d'avance

un petit coup de firebug
pour voir qu'il y a un playeur flash qui lit un LJpeg.

http://216.62.222.100/mjpg/video.mjpg

le début du flux est ÿØÿþ qui correspond bien au format.

Te reste donc à lire du MJpeg sur flux streamer
