Hallo zusammen,
ich habe einen Videoplayer der mehrere Videos hintereinander abspielen kann, diese Videos werden über eine Xml Datei geladen. Jetzt muss ich den Videopalyer aber so anpassen das er ohne xml auskommt, also die Videos im AS selber geladen werden. Ich bin jetzt nicht ganz so fit in AS3, deshalb wollte ich hier mal Fragen ob mir da jemand einen Tip geben kann wie ich das umsetzen kann.
Ich habe auch die Datei angehängt
