Lire Flux video d'une camera IP HikVision sous Java

Bonjour,
je veux lire le flux video d'une camera IP et l'affiche dans une JFrame, j'utilisé un code de lecture d'une camera Axis mais c'a n'a pas fonctionner pour moi.je me bloque dans l'erreur suivante :
Not a JPEG file: starts with 0x3c 0x68
voici le code :

package ConnectCam;

l'erreur et sur : image = decoder.decodeAsBufferedImage();

si qu'il q'un a une idée SVP
