Salut,

Je débute en Java et IOIO

Je souhaite transmettre les images vidéo d'un Android Serveur (Galaxy S 4.4.4) vers un Android Client (Elephone P6000 4.4.4) sur le port 8002 qui est en écoute.

Mais je n'ai pas d'erreur, mais pas de vidéo non plus.
le port d'écoute est ouvert 8002, lorsque je fais un échange de messages (dataOutputStream, dataInputStream) ça fonctionne.
L'Android Client fonctionne avec une vidéo issue de Youtube.
Les images de la camera de l'Android Serveur apparaissent uniquement sur L'Android Serveur (videoView) si je mets un port fermé exemple 50.

Si quelqu'un a une idée... là je suis perdu.

Merci 



Le MainActivity du serveur
