| 30 | * Der PlayActor loest das Abspielen eines Titels aus. | |
| 31 | * | |
| 32 | * Das koennte auch als Shell-Skript geschehen, aber abhaengig | |
| 33 | * vom verwendeten Abspielprogramm benoetigt man das Prozessobjekt | |
| 34 | * des laufenden Abspielprozesses im Verlauf des Abspielens noch, um | |
| 35 | * weitere Kommandos zu senden. | |
| 36 | * | |
| 37 | * Beim Abspieler mpv werden Kommandos allerdings ueber Unix Domain | |
| 38 | * Sockets gesendet, hierfuer waere also das Objekt des laufenden | |
| 39 | * Abspielprozesses nicht noetig. Man benoetigt es aber auch um | |
| 40 | * festzustellen, ob der Abspielprozess beendet ist. | |
