在Inno Setup安装过程中播放声音

问题描述

我希望使用Inno Setup为我的应用创建安装脚本，但是我希望它在安装过程中播放声音文件，这可能吗?如果可以的话，您能指出我正确的方向！

I wish to use Inno Setup to create an install script for my app but I would like it to play a sound file during install, is this possible? if so can you point me in the right direction!

推荐答案

1. Inno Media Player

您可以使用 Inno Media Player 库(对不起进行自我推广).这是一个示例，用于播放设置文件中存储为临时文件的音频文件.

1. Inno Media Player

You can use the Inno Media Player library (sorry for self promotion). Here is an example of its use for playing audio file stored as a temporary file inside of a setup.

请注意，Inno Media Player是Unicode库，因此您只能将其与Inno Setup的Unicode版本一起使用，而不能与ANSI版本一起使用！不支持ANSI版本的Inno Setup ...！

Please note, that Inno Media Player is a Unicode library, and so you can use it only with Unicode versions of Inno Setup, not with ANSI ones! There is no support for ANSI versions of Inno Setup...!

[Setup]
AppName=Media Player Project
AppVersion=1.0
DefaultDirName={pf}\Media Player Project

[Files]
Source: "AudioFile.mp3"; Flags: dontcopy
Source: "MediaPlayer.dll"; Flags: dontcopy

[Code]
const
  EC_COMPLETE = $01;
type
  TDirectShowEventProc = procedure(EventCode, Param1, Param2: Integer);

function DSGetLastError(var ErrorText: WideString): HRESULT;
  external 'DSGetLastError@files:mediaplayer.dll stdcall';
function DSPlayMediaFile: Boolean;
  external 'DSPlayMediaFile@files:mediaplayer.dll stdcall';
function DSStopMediaPlay: Boolean;
  external 'DSStopMediaPlay@files:mediaplayer.dll stdcall';
function DSSetVolume(Value: LongInt): Boolean;
  external 'DSSetVolume@files:mediaplayer.dll stdcall';
function DSInitializeAudioFile(FileName: WideString;
  CallbackProc: TDirectShowEventProc): Boolean;
  external 'DSInitializeAudioFile@files:mediaplayer.dll stdcall';

procedure OnMediaPlayerEvent(EventCode, Param1, Param2: Integer);
begin
  if EventCode = EC_COMPLETE then
  begin
    { playback is done, so you can e.g. play the stream again, play another }
    { one using the same code as in InitializeWizard (in that case would be }
    { better to wrap that in some helper function) or do just nothing }
  end;
end;

procedure InitializeWizard;
var
  ErrorCode: HRESULT;
  ErrorText: WideString;
begin
  ExtractTemporaryFile('AudioFile.mp3');
  if DSInitializeAudioFile(ExpandConstant('{tmp}\AudioFile.mp3'),
    @OnMediaPlayerEvent) then
  begin
    DSSetVolume(-2500);
    DSPlayMediaFile;
  end
  else
  begin
    ErrorCode := DSGetLastError(ErrorText);
    MsgBox('TDirectShowPlayer error: ' + IntToStr(ErrorCode) + '; ' +
      ErrorText, mbError, MB_OK);
  end;
end;

procedure DeinitializeSetup;
begin
  DSStopMediaPlay;
end;

2.低音音频库

或者您可以使用例如 Bass Audio Library 库，该库对于非商业用途.例如，要对该库进行无限循环播放，可以使用如下脚本.

2. Bass Audio Library

Or you can use for instance the Bass Audio Library library, which is free for non-commercial use. To play for instance an infinite loop with that library, you might use script like follows.

此脚本和库与Inno Setup，ANSI和Unicode两个版本兼容.

This script and the library are compatible with both versions of Inno Setup, ANSI and Unicode.

[Setup]
AppName=Bass Audio Project
AppVersion=1.0
DefaultDirName={pf}\Bass Audio Project

[Files]
Source: "Bass.dll"; Flags: dontcopy
Source: "AudioFile.mp3"; Flags: dontcopy

[Code]
const
  BASS_SAMPLE_LOOP = 4;
  BASS_UNICODE = $80000000;
  BASS_CONFIG_GVOL_STREAM = 5;
const
  #ifndef UNICODE
    EncodingFlag = 0;
  #else
    EncodingFlag = BASS_UNICODE;
  #endif
type
  HSTREAM = DWORD;

function BASS_Init(device: LongInt; freq, flags: DWORD;
  win: HWND; clsid: Cardinal): BOOL;
  external 'BASS_Init@files:bass.dll stdcall';
function BASS_StreamCreateFile(mem: BOOL; f: string; offset1: DWORD;
  offset2: DWORD; length1: DWORD; length2: DWORD; flags: DWORD): HSTREAM;
  external 'BASS_StreamCreateFile@files:bass.dll stdcall';
function BASS_ChannelPlay(handle: DWORD; restart: BOOL): BOOL;
  external 'BASS_ChannelPlay@files:bass.dll stdcall';
function BASS_SetConfig(option: DWORD; value: DWORD ): BOOL;
  external 'BASS_SetConfig@files:bass.dll stdcall';
function BASS_Free: BOOL;
  external 'BASS_Free@files:bass.dll stdcall';

procedure InitializeWizard;
var
  StreamHandle: HSTREAM;
begin
  ExtractTemporaryFile('AudioFile.mp3');
  if BASS_Init(-1, 44100, 0, 0, 0) then
  begin
    StreamHandle := BASS_StreamCreateFile(False,
      ExpandConstant('{tmp}\AudioFile.mp3'), 0, 0, 0, 0,
      EncodingFlag or BASS_SAMPLE_LOOP);
    BASS_SetConfig(BASS_CONFIG_GVOL_STREAM, 2500);
    BASS_ChannelPlay(StreamHandle, False);
  end;
end;

procedure DeinitializeSetup;
begin
  BASS_Free;
end;
