| 27 | * Der mpv Abspieler erhaelt Kommandos waehrend des Abspielens | |
| 28 | * ueber Unix Domain Sockets. Da diese erst mit Java 16 untersuetzt | |
| 29 | * werden und Java 16 fuer den Raspberry Pi noch nicht erhaeltlich | |
| 30 | * ist, werden diese Kommandos als Shell-Skript unter Verwendung | |
| 31 | * des Linux-Programms socat gesendet. | |
| 32 | * | |
| 33 | * Der Shell Actor fuehrt Skripte aus. Wenn ein Kommando Parameter | |
| 34 | * erfordert, werden diese aus dem Query-Teil des HTTP-Aufrufes | |
| 35 | * entnommen. | |
