dsj - DirectShow <> Java wrapper

[algorismi]

Hoffe, dass sich jemand hier mit dem DSJ auskennt,

meine erste Frage ist, hat jemand zu DSJ ein Tutorial?

und meine zweite Frage ist, ich versuche einen RTSP-Stream mithilfe von DSJ abzuspielen,
bekomme aber folgende Fehlermeldung:

woran liegt diese Fehlermeldung, warum wird der Server nicht gefunden, wenn ich versuche den Stream per VLC zu abspielen, dann funktioniert es.

danke schon mal im voraus

Kennt sich denn niemand mit DSJ aus oder hat bis jetzt niemand was darüber gehört??

OK mal ne andere Frage, wie kann ich denn in Java einen H.264 RTSP Stream darstellen?

hat sich erledigt, habe herausgefunden wo genau der fehler liegt.
