Hallo DJ,
Hier findest du die Sourcen.
(Translation: Here are the sources).
But NSV is dead in my oppinion, eventhough Red5.
I've spend hours of NSV / Flash research, i used Red5, Xuggler, Smelters sources, but after 3 years i couldn't produce anything really stable with transcoding nsv to flash on the fly. I also wrote a distributer, which spreads one rtmp stream (transcoded from nsv) to several red5 servers, but none of this was stable enough for business products.
After all i switches to wowza, which is the best choise, because nobody seems to use or develop red5/xuggler anymore.
