xbass.dll - Music plugin

[BLACKFIRE69]

Can someone share me an example as how to use .ogg files in IXBass which was supported after xBass.dll v3.0?

it's nothing but you need to have decoders next to the 'XBass.dll'. In this case, they are 'ogg.dll' and 'vorbis*.dll'.



* What's new with this release:

1. Compiled in Delphi XE to reduce the file size.
- FileSize: 4.51 MB --> 497 KB (Saved: 90%)

2. Play through memory.
- Since this build, you can play files through memory, instead of having them on the hard drive.
- However, you need to use 'InnoSetup Enhanced Edition' or 'FXStream' to utilize this feature.

function xbassCreateFromMem(AHandle: HWND; const Buffer: PAnsiChar; const Count, BassType: Cardinal; ASpeed: Single; RepeatOn: Boolean; ACallback: TXBassCallback1): Boolean;

function xbassChangeMem(const Buffer: PAnsiChar; const Count: Cardinal): Boolean;

--------------------------------

type
  IXBass = Interface(IUnknown)
    '{3A515F05-FBAE-4D1E-80A0-808E6FAF3187}'
    ...
    function FCreateFromMem(AHandle: HWND; const Buffer: PAnsiChar; const Count, BassType: Cardinal; ASpeed: Single; RepeatOn: Boolean; ACallback: TXBassCallback1): Boolean;
    function ChangeMem(const Buffer: PAnsiChar; const Count: Cardinal): Boolean;
	...
 end;

* InnoSetup Enhanced Edition:

procedure InitializeWizard();
var
  Buffer: AnsiString;
  Count: Cardinal;
begin
  //
  Count := ExtractTemporaryFileSize('{#MusicFileOnly}');
  SetLength(Buffer, Count);
  ExtractTemporaryFileToBuffer('{#MusicFileOnly}', CastAnsiStringToInteger(Buffer));
  //

  ExtractTemporaryFile('ogg.dll');
  ExtractTemporaryFile('vorbis.dll');
  ExtractTemporaryFile('vorbisenc.dll');
  ExtractTemporaryFile('vorbisfile.dll');

  CreateOrChange;
  PlayNextBtn.Enabled := False;
  PlayPrevBtn.Enabled := False;

  if not xbassCreateFromMem(WizardForm.Handle,
                            Buffer,
                            Count,
                            C_XBASS_OGG,
                            1, True, @MusicCallback) then
    MsgBox('XBass - error(s) occured while creating.', mbError, MB_OK);
end;

* FXStream:

procedure InitializeWizard();
var
  Buffer: AnsiString;
  Count: Cardinal;
begin
  //
  Count := FXUnPckrExtractFileSize('{#MusicFileOnly}');
  SetLength(Buffer, Count);
  FXUnPckrExtractToBuffer2A('{#MusicFileOnly}', Buffer, Count);
  //

  ExtractTemporaryFile('ogg.dll');
  ExtractTemporaryFile('vorbis.dll');
  ExtractTemporaryFile('vorbisenc.dll');
  ExtractTemporaryFile('vorbisfile.dll');

  CreateOrChange;
  PlayNextBtn.Enabled := False;
  PlayPrevBtn.Enabled := False;

  if not xbassCreateFromMem(WizardForm.Handle,
                            Buffer,
                            Count,
                            C_XBASS_OGG,
                            1, True, @MusicCallback) then
    MsgBox('XBass - error(s) occured while creating.', mbError, MB_OK);

  { CleanUp }
  FXUnPckrFree;
end;
