Méthode	Description
ChannelIsActive ( int handle ) : BASSActive
ChannelPlay ( int handle, bool restart ) : bool
ChannelRemoveLink ( int handle, int chan ) : bool
ChannelSetLink ( int handle, int chan ) : bool
CommandThread ( ) : void
CreateCommandThread ( ) : void
GetCurrentStream ( ) : MediaPortal.MusicPlayer.BASS.MusicStream	Returns the Current Stream
GetSoundDevice ( ) : int	Get the Sound devive as set in the Configuartion
GetWasApiFormats ( ) : void	Detect the supported output formats for WASAPI
GetWasApiSpeakers ( ) : int	WASAPI doesnj't provide a way to ask the driver on the maximum of supported speakers. So we try to enumerate the channels and detect the attached speakers.
HandleBassError ( string methodName ) : void	Displays Information about a BASS Exception
HandleCueFile ( string &filePath, bool endOnly ) : bool	Parse the Cue file. Return a Fake Cue track and adjest the playback position within the file.
HandleSongEnded ( ) : void	Handle Stop of a song

InitDirectSoundDevice ( ) : bool	Initialise the DirectSound Device
InitWasapi ( ) : bool	Initialises the Wasapi Device
Initialize ( ) : void	Initialise the Visualisation Window and Load Decoder/DSP Plugins The BASS engine itself is not initialised at this stage, since it may cause S/PDIF for Movies not working on some systems.
OnAppFormDisposed ( object sender, EventArgs e ) : void	The Main Form is disposed, so dispose the player
OnMusicStreamMessage ( object sender, MediaPortal.MusicPlayer.BASS.MusicStream action ) : void	This Message is sent from a MusicStream
OnNewAction ( MediaPortal.GUI.Library.Action action ) : void
PlayInternal ( string filePath ) : bool	Called to start playback of next files internally, without makinbg use of g_player. This gives us the capability to achieve gapless playback.
