/**
|
* Die Klasse Server implementiert die HTTP-Schnittstelle zum
|
* Mediaplayer. Es wird ein Player-Prozesss fuer das Abspielen
|
* eines Titels gestartet. Mit Stopp oder Ende des Titels endet
|
* auch der Abspielprozess.<br>
|
* <br>
|
* zum Abspielen:<br>
|
* /calypso/play?title=http://ein.titel.mp3&r=http://rueckmelde.url<br>
|
* <br>
|
* waehrend des Abspielens:<br>
|
* /calypso/pause<br>
|
* /calypso/seek?pos=[sekunden]<br>
|
* /calypso/stop<br>
|
* <br>
|
* sonstige Funktionen:<br>
|
* /calypso/ping<br>
|
* /calypso/server/stop<br>
|
* <br>
|
* verworfene Funktionen<br>
|
* /calypso/vol-inc<br>
|
* /calypso/vol-dec<br>
|
* Die Lautstaerke wird in aller Regel am Geraet geregelt, an das der
|
* Zuspieler (der Raspi) angeschlossen ist. Eine Regelung ueber den
|
* Zuspieler ist daher eher selten erforderlich.
