Prima release di un player realizzato con le nuove API per caricare i video di youTube direttamente in flash, non ho trovato molti esempi così ho deciso di farne uno, ma c’è ancora da lavorare…
Tanto per cambiare.

Il sorgente sarà disponibile a giorni, nel frattempo ecco il codice utilizzato

ho notato che cliccando sul logo di youTube, per andare al link relativo al video, il player si blocca, così in attesa di capire perchè succede, c'ho messo sopra un bottone trasparente.
