Controlling BTplay

BTPlay is an external music player that is used by the chumby Control Panel to play audio files and streams asynchronously. It is implemented as a persistent daemon that is controlled by a UNIX pipe, typically from the Flash Lite Player, or through some stub applications.

Several ASnative() calls have been added to the Flash Lite implementation to control this daemon.

PlayAudio

_PlayAudio = ASnative(5,151);
_PlayAudio('/mnt/usb/somemusicfile.mp3');

StopAudio

_StopAudio = ASnative(5,134);
_StopAudio();

PauseAudio

_PauseAudio = ASnative(5,132);
_PauseAudio();

ResumeAudio

_ResumeAudio = ASnative(5,133);
_ResumeAudio();

PlayerState

_PlayerState = ASnative(5,131);
playerState = _PlayerState();

returns -1 if player daemon not running, 0 if paused, 2 if playing a track

SongAttributes

_SongAttributes = ASnative(5,135);
attrs = _SongAttributes();

returns XML of the information about the currently playing track, typically MP3 tags and other metadata
