Gentili utenti,
vi scrivo per chiedervi aiuto iguardo il problema in oggetto.
Possego una IP CAM Vivotek IP3133 collegata ad un modem router TP-LINK TD-W8920G
Ho installato la JMF 2.1.1e
javac -version: 1.6.0_03
java -version: 1.6.0_07
Ho creato un programma ma mi da due warning, esattamente uguali, quando lo compilo:
warning: com.sun.image.codec.jpeg.JPEGImageDecoder is Sun proprietary API and may be removed in a future release
In basso vi posto il codice che attualmente utilizzo però credo ci siano dei problemi con gli indirizzi IP (ma non credo siano solo questi):
String jpgURL = "http://192.168.1.100/cgi-bin/video.jpg"; e questo penso sia giusto in quanto mi da uno snapshot.
Sono invece insicuro sul seguente: public String mjpgURL= "http://192.168.1.100/video.cgi";
L'indirizzo http://192.168.1.100 è l'indizzo privato della cam collegata in rete
Spero qualcuno possa aiutarmi
