捕获电脑的声音放到手机播放

在pc上使用adb命令：adb forward tcp:4626 tcp:4883，在PC上建立4626端口通信数据将被重定向到手机端server的4883端口；然后初始化socket，连接到手机4626端口，进行socket通信。PC端代码如下：

[html]
DWORD WINAPI usbThreadFunc(LPVOID threadNum)
{
    int length;
    CString temp;
    if(!initAdb())//adb init
    {
        MessageBox(0, L"初始化手机出错！", L"提示", MB_OK);
        return 0;
    }
    if(!InItClientSock())//socket init
    {
        MessageBox(0, L"初始化IP地址出错！", L"提示", MB_OK);
        return 0;
    }
    if(!USBConnectSock((HWND)threadNum))//connect socket
    {
        MessageBox(0, L"连接IP地址出错！", L"提示", MB_OK);
        return 0;
    }
    //等待连接的时候，连接可能被取消。
    if(clientThreadRun)
    {
    }
    else
    {
        MessageBox(0, L"用户取消！", L"提示", MB_OK);
        return 0;
    }
    SetDlgItemText( (HWND)threadNum, IDC_SOUNDFILE, TEXT("&USB Disconnect") );
    EnableWindow( GetDlgItem( (HWND)threadNum, IDC_RECORD ), TRUE );
    EnableWindow( GetDlgItem( (HWND)threadNum, IDC_BUTTON_WIFI ), FALSE );
    while(clientThreadRun)
    {
        if( (length = recv(clientSock,(char*)recv_message_client,sizeof(recv_message_client),0))>0)
        {
            memset(recv_message_client, 0, sizeof(recv_message_client));
            LogPrintf(recv_message_client);
        }
    }
    return 0;
}

DWORD WINAPI usbThreadFunc(LPVOID threadNum)
{
int length;
CString temp;
if(!initAdb())//adb init
{
  MessageBox(0, L"初始化手机出错！", L"提示", MB_OK);
  return 0;
}
if(!InItClientSock())//socket init
{
  MessageBox(0, L"初始化IP地址出错！", L"提示", MB_OK);
  return 0;
}
if(!USBConnectSock((HWND)threadNum))//connect socket
{
  MessageBox(0, L"连接IP地址出错！", L"提示", MB_OK);
  return 0;
}
//等待连接的时候，连接可能被取消。
if(clientThreadRun)
{
}
else
{
  MessageBox(0, L"用户取消！", L"提示", MB_OK);
  return 0;
}
SetDlgItemText( (HWND)threadNum, IDC_SOUNDFILE, TEXT("&USB Disconnect") );
EnableWindow( GetDlgItem( (HWND)threadNum, IDC_RECORD ), TRUE );
EnableWindow( GetDlgItem( (HWND)threadNum, IDC_BUTTON_WIFI ), FALSE );
while(clientThreadRun)
{
  if( (length = recv(clientSock,(char*)recv_message_client,sizeof(recv_message_client),0))>0)
  {
   memset(recv_message_client, 0, sizeof(recv_message_client));
   LogPrintf(recv_message_client);
  }
}
return 0;
}

这里说道最重要的是捕获声音，下面的代码启动了一个线程来处理捕获到的声音：

[html]
DWORD WINAPI captureThreadFunc(LPVOID hDlg)
{
    DWORD dwResult;
    while(g_bRecording)
    {
        dwResult = MsgWaitForMultipleObjects( 1, &g_hNotificationEvent, FALSE, INFINITE, QS_ALLEVENTS );
        switch( dwResult )
        {
        case STATUS_WAIT_0://case WAIT_OBJECT_0 + 0:

            RecordCapturedData();
            break;
        }
    }
    return 0;
}

DWORD WINAPI captureThreadFunc(LPVOID hDlg)
{
DWORD dwResult;
while(g_bRecording)
{
  dwResult = MsgWaitForMultipleObjects( 1, &g_hNotificationEvent, FALSE, INFINITE, QS_ALLEVENTS );
  switch( dwResult )
  {
  case STATUS_WAIT_0://case WAIT_OBJECT_0 + 0:

   RecordCapturedData();
   break;
  }
}
return 0;
}

在创建捕获声音的设备的时候，会创建一个事件，这个事件就是捕获到一定长度的声音之后（比如2K大小的声音），会发出一个通知，告诉你去处理。上面的线程，就是一直待等待这个事件，然后再去处理捕获到的声音，把声音发送给socket，交给手机处理，代码：

[html]
HRESULT RecordCapturedData()
{
    HRESULT hr;
    VOID*   pbCaptureData    = NULL;
    DWORD   dwCaptureLength;
    VOID*   pbCaptureData2   = NULL;
    DWORD   dwCaptureLength2;
    DWORD   dwReadPos;
    DWORD   dwCapturePos;
    LONG lLockSize;

    if( NULL == g_pDSBCapture )
        return S_FALSE;

    if( FAILED( hr = g_pDSBCapture->GetCurrentPosition( &dwCapturePos, &dwReadPos ) ) )
        return DXTRACE_ERR_MSGBOX( TEXT("GetCurrentPosition"), hr );

    lLockSize = dwReadPos - g_dwNextCaptureOffset;
    if( lLockSize < 0 )
        lLockSize += g_dwCaptureBufferSize;

    // Block align lock size so that we are always write on a boundary
    lLockSize -= (lLockSize % g_dwNotifySize);

    if( lLockSize == 0 )
        return S_FALSE;

    // Lock the capture buffer down
&n
