I have a friend who made one for his car. I'll point him in this threads general direction.

What the hell does that post mean?

Since you have all the C code, I'll give you something better. Here's some C++ code (Win32). Mp3s are eaaassyyy...

mp3.h

/* NECROSOFT MP3 PLAYING BITS  */
/* ROB AT YOUR OWN DISCRETION  */
/* [url="HTTP://WWW.NECROSOFT.IE"]HTTP://WWW.NECROSOFT.IE[/url]     */
#ifndef _MP3H_
#define _MP3H_

#define WIN32_LEAN_AND_MEAN
#include <windows.h>
#include <mmsystem.h>

class cMp3
{
private:
 IBaseFilter   *  pif;
 IGraphBuilder *  pigb;
 IMediaControl *  pimc;

 bool    ready;

public:
	cMp3();
	~cMp3();

	void Play();
	void Pause();

	int Load(LPSTR filename);

};

#include "Mp3.h"

cMp3::cMp3()
{
	pif = NULL;
	pigb = NULL;
	pimc = NULL;
	pimex = NULL;
	
	ready = false;
	
	CoInitialize(NULL);
}

cMp3::~cMp3()

	Cleanup();
}

void cMp3::Cleanup()
{
	CoUninitialize();
	
	if (pimc)

		pigb = NULL;
	}
	
	if(pimc)
	{
		pimc->Release();
		pimc = NULL;
	}
	
	if(pimex)
	{
		pimex->Release();
		pimex = NULL;
	}
}

int cMp3::Load(LPSTR szFile)
{
	WCHAR wFile[MAX_PATH];
	MultiByteToWideChar(CP_ACP, 0, szFile, -1, wFile, MAX_PATH);
	
	if (SUCCEEDED(CoCreateInstance( CLSID_FilterGraph,

		IID_IGraphBuilder,
		(void **)&this->pigb)))
	{
		pigb->QueryInterface(IID_IMediaControl, (void **)&pimc);
		pigb->QueryInterface(IID_IMediaEventEx, (void **)&pimex);
		
		if (SUCCEEDED(pigb->RenderFile(wFile, NULL)))
		{
			ready = true;
		}  
	}
	return (ready);
}

void cMp3::Play()
{
	if (ready)
	{
		pimc->Run();
	}
}

void cMp3::Pause()
{
	if (ready)
	{
		pimc->Pause();
	}
}

void cMp3::Stop()
{
	if (ready)
	{
		pimc->Stop();
	}
}

Usage:

cMp3 mp3madness;
mp3madness.Load("Strauss - Also Sprach Zarathustra.mp3");
mp3madess.Play();

Script Kiddies of the world can now put mad tunes to their Win32 hax04 programs.

yea but can they write a mp3 virus,
like in napster when something is searched for.. lets say "x.mp3".

the virus goes and pretends to be "x.mp3"
and if the user downloads it.. it executes on play. then to infect the users computer and do the same to the next john doe that searches for a song. And on a certain date it would fe<k with computers around the world that downloades it.

/me thinks this is something of a nasty nature.. ;p

Eh...no, users tend to play(/decode) mp3s rather than
executing them. Yes, you could send them an executable that
played music but also did something nasty, but that's just a trojan and not exactly a new idea...

Kastro

hmmm but have you ever seen it or heard of it being done?

Kastro

well has it?
