 /**
- * Es koennen mehrere Varianten beim Abspielen verwendet werden.
- * 
- * Abspielen eines Titels
- * abspielenMitParameternUndRueckmeldung(urlStr, null, null, 1)
- * 
- * Abspielen eines Titels mit Rueckmeldung (z.B. fuer Playlisten)
- * abspielenMitParameternUndRueckmeldung(urlStr, null, meldeUrlStr, 1)
- * 
- * Abspielen mit Parametern
- * abspielenMitParameternUndRueckmeldung(urlStr, parameter, null, 1)
- * 
- * Abspielen mit Parametern und Rueckmeldung
- * abspielenMitParameternUndRueckmeldung(urlStr, parameter, meldeUrlStr, 1)
- * 
- * Token wird zur Zeit nicht genutzt, hier kann einfach eine beliebige
- * Zahl uebergeben werden.
- * 
- * Die drei Parameter t, p, r werden als Query im URL erwartet. Beispiele:
- * t = titel
- * p = parameter
- * r = url fuer rueckmeldung
- * 
- * 
- * /avd/play?t=/Pfad/zum/Titel.mp3
