durch Zufall bin ich auf EG gesto├ƒen und von der einfachen Bedienung ├╝berzeugt. Nun m├Âchte ich ein Plugin f├╝r das Programm =http://www.albumplayer.com schreiben. Dieses Programm verf├╝gt ├╝ber ein Remote Control Interface via API Funktion. Da ich hier im Forum keine ausreichenden Infos ├╝ber das Entwickeln von Plugins finden konnte habe ich mir alle in EG enthaltenen Plugins angesehen und das Winamp Plugin als tauglich zum ├ñndern und testen befunden. Da ich mich mit Python gerade erst vertraut mache brauche ich etwas Hilfe.
Hier erst mal die Daten:
Windows XP Sp2
EG Version 0.3.5c 908
FM MCE Toshiba
AlbumPlayer Interface :
Window Messsage (Fenster Nachricht an Albumplayer)
WM_REMOTE_CONTROL = WM_USER + 10;
Parameter:
wparam = 1 -> Play/Pause (Toggle)
wparam = 2 -> Stop
wparam = 3 -> Next Track
wparam = 4 -> Prev Track
wparam = 5 -> Play
wparam = 6 -> Pause
wparam = 7 -> Increase Play Speed Factor
wparam = 8 -> Decrease Play Speed Factor
wparam = 9 -> Seek
lparam -> Position in ms
wparam = 10 -> Set Volume
lparam -> Volume on a scale of 0 to 100
wparam = 11 -> Increase/Decrease Volume
lparam -> Steps on a volume scale of 0 to 100 (step max -100 to 100)
wparam = 12 -> Mute (Toggle)
wparam = 100 -> BringToFront
wparam = 101 -> Exit
WM_SUBSCRIBE_FOR_NOTIFICATIONS = WM_USER + 11;
The AP can send the following notifications using different parameters:
Now playing info:
wparam = 6 -> track progress changed
lparam -> progress in milliseconds
Playlist:
wparam = 10 -> playlist is changed
Player status:
wparam = 1 -> play state changed
lparam = 0 -> stopped
lparam = 1 -> playing
lparam = 2 -> paused
wparam = 12 -> albumplayer volume changed
lparam -> volume percentage (0-100)
General:
wparam = 2 -> albumplayer will be closed
Das ganze habe ich nun fogendermaßen als Plugin umgesetzt.
Code: Select all

Andere Funktionen der Fernbedienung arbeiten in EG einwandfrei.
Ich gehe also davon aus das sich ein krasser Fehler in dem Plugin befindet !
F├╝r jeden Hinweis bin ich dankbar.
