In der dritten Woche hatten wir die Aufgabe einen Video Player zu coden. Meine Version erlaupt das Starten/Pausieren mit einem Umschaltknopf und einen Restart-Button. Der Code ist noch nicht Perfekt ausgereift. Um ein Nutzbares Resultat zu erhalten, müsste ich noch weitere Zeit investieren. Coding Space Video
