| | | * 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 |
| | | * |
