FMOD Decides it doesn't want to...

ahluka · 02-15-2006, 04:20 AM

I've decided to use FMOD after deciding I don't like OpenAL (don't ask) and twas all going fine, but sometimes it just decides not to load the sound files.

This snippet works, but only sometimes:

Code:

result = fmod_system->createStream ("\\Condensed.mp3", FMOD_DEFAULT, 0, &sound);
if (result != FMOD_OK) {
    cout << "\tFAILED\n";
    exit (1);
}

It works fine (Condensed.mp3 is in the same directory) but sometimes it just fails. If I change the file I want to load - even when it's in the same place - it sometimes doesn't work. The funny thing is it always works if I place the file in the root directory (C:\\ for example).

Anyone have a similar problem?

does removing the '\\' make a difference?

ahluka · 02-15-2006, 04:27 AM

Nope I get the same problem.
EDIT: When it doesn't load it from the same dir, if I move it to C:\\Condensed.mp3 then it loads it, and I re-compile it using "\\Condensed.mp3", it suddenly can see it.

Then you could get the path to your exe and then strcat \\Condensed.mp3. I had to do that once for something can't quite remember what though.

ahluka · 02-15-2006, 04:47 AM

Ok I'll try that.
EDIT: I assume there's a winAPI call to get that - to save me hard coding it?

This will play MP3's through DirectShow. Most of the source originates from Special Effects Game Programing with DirectX 8. All it needs is a window handle.

Code:

#ifndef CDXSHOWWND
#define CDXSHOWWND

#include <dshow.h>

class CDXShowWnd
{
  protected:
    IGraphBuilder *m_pGraph;
    IVideoWindow  *m_pVidWnd;
    IMediaControl *m_pMedia;
    IMediaEvent   *m_pEvent;


    HWND          m_Hwnd;
  public:
    CDXShowWnd(void):m_pGraph(NULL),m_pVidWnd(NULL),m_Hwnd(0) {}
    virtual ~CDXShowWnd(void)
    {
      ShutDown();
    }

    void Create(HWND hwnd)
    {
      //Create filter graph
      CoCreateInstance(CLSID_FilterGraph,NULL,CLSCTX_INPROC,IID_IGraphBuilder,
                       (void **)&m_pGraph);
      
      m_pGraph->QueryInterface(IID_IVideoWindow,(void **)&m_pVidWnd);
      m_pGraph->QueryInterface(IID_IMediaControl,(void **)&m_pMedia);
      m_pGraph->QueryInterface(IID_IMediaEvent,(void **)&m_pEvent);

      //Set window
      m_pVidWnd->put_Owner((OAHWND)hwnd);
      m_pVidWnd->put_WindowStyle(WS_CHILD | WS_CLIPSIBLINGS);
      RECT grc;
      ::GetClientRect(hwnd,&grc);
      m_pVidWnd->SetWindowPosition(0,0,grc.right,grc.bottom);
    }

    void Play(const unsigned short *File)
    {
      m_pGraph->RenderFile(File,NULL);
      m_pMedia->Run();

      long lDone=0;
      m_pEvent->WaitForCompletion(0,&lDone);

    
    }

    void ShutDown(void)
    {
      m_pMedia->Release();
      m_pEvent->Release();
      m_pVidWnd->Release();
      m_pGraph->Release();
      CoUninitialize();
    }

};

#endif

You will need to link with quartz.lib and strmiids.lib and of course have access to dshow.h.

To respond to messages consult the DirectShow SDK on how to use IMediaEvent and callbacks.

Cheers Bubba; I was going to ask about using DirectX for sound if all else failed.

**Bubba** · 02-15-2006, 02:05 PM

DirectSound won't natively load MP3's nor will DirectMusic. To get the spec for MP3's you must pay for them. But DirectShow does support them and you can use DirectShow as your sound system for simple apps.

~Kyo~ · 02-15-2006, 03:16 PM

Or in theory... you are typing \\Condensed.mp3 you could use just Condensed.mp3 to get from the same directory or for say another dir you could sound\\Condensed.mp3. \\Condensed.mp3 may have some strange effects. I don't know why I didn't think of it sooner... but it hit me when I was working on some code...

Code:

player->SetImage("art/man.bmp",APAL);

I know this works although I use / instead of \\
Maybe this will help you some.

Try to use:
".\\Condensed.mp3" or "./Condensed.mp3"
The dot at start tells that Condensed is in the same folder where the executable is running (or debugging). Almost the same way the double dot, tells the file is at the "one folder above" folder. It reminds a little bit of "DOS", Unix, e.t.c.

I hope this to work..

Ps. For other folder (examples) you can use: ".\\x\\y\\z.mp3" (or "./x/y/z.mp3"). Or "..\\..\\x\\y\\z.mp3" ("../../x/y/z.mp3") e.t.c. At least I never had such problems using the dots. (I have never try it without the dots).
