XBMC event based commands

[menakite]

Copy xbian-xbmc-player.conf to, for example, xbmc-json-lights.conf (sudo cp xbian-xbmc-player.conf xbmcplayer-json-lights.conf).

Then delete everything between "pre-start script" and "end script", the same applies for "post-stop script"/"end script" (you'd need sudo to modify it: sudo nano xbmcplayer-json-lights.conf).

"pre-start script" is executed when the playback starts (or unpaused) and "post-stop script" when the playback ends.

The shell commands to control your lights (I can't really help on this, check your documentation) should be added between "pre-start/post-stop script" and "end script".

If you want to execute the same commands when the playback is paused you'd need to change the line:
stop on player ACTION=STOP
to:
stop on player ACTION=STOP or player ACTION=PAUSE
