A very simple MP3 Player

Download source files - 12 Kb

Introduction

I made a little sample program that enables you to play MP3 files without needing the AUDIOX library. I used the Windows Library VFW32.Lib

Just put the VFW32.lib in the Linker's space (Alt +F7) and add

#include "vfw.h"

to your principal file.

Once you've done this, you just need to use the MCI commands:

Steps :

Create a private variable HWND m_Video and BOOL Pause;
in the OnInitDialog set m_Video = NULL;
Put almost the Play button and add this source code on

Here are the functions I use in my dialog class to play/pause/resume and stop video playback.

m_Play is the 'Play' button control, m_Pause is the pause/resume button, Pause is a boolean value, and m_Video is a HWND.

void CAVIPlayerDlg::OnPlay() 
{
	m_Video = NULL;
	
	if(m_Video == NULL)
	{
		m_Video = MCIWndCreate(this->GetSafeHwnd(),
			AfxGetInstanceHandle(),
			WS_CHILD | WS_VISIBLE|MCIWNDF_NOMENU,m_Path);
		
	}
	else
	{
		MCIWndHome(m_Video);
	}
	
	MCIWndPlay(m_Video);
	Pause = FALSE;
	m_Play.EnableWindow(FALSE);
	
}

void CAVIPlayerDlg::OnPause() 
{
	if(Pause)
	{
		m_Pause.SetWindowText("Pause");
		MCIWndResume(m_Video);
		Pause = FALSE;
	}
	else
	{
		m_Pause.SetWindowText("Resume");
		MCIWndPause(m_Video);
		Pause = TRUE;
	}
}

void CAVIPlayerDlg::OnCancel() 
{
	if(m_Video !=NULL)
	{
		MCIWndDestroy(m_Video);
		OnOK();
	}
	CDialog::OnCancel();
}

void CAVIPlayerDlg::OnStop() 
{
	// TODO: Add your control notification handler code here

	MCIWndStop(m_Video);
	if(m_Video !=NULL)
	{
		MCIWndDestroy(m_Video);
	}
	m_Play.EnableWindow(TRUE);
}

I Suggest you to refer to the MCI Reference on the net at http://msdn.microsoft.com/library/psdk/multimed/mciwnd_3stv.htm

I also include an AVI player in this program. :-)

That's all for this !

Dear Blaze
I 've used your code. It 's simple but greate enough to run properly. But there 's still one problem I cannot overcome. I'm writting a "Multi AVI Player" Application using MultiThreading technique. When I tried to run many AVI files on many dialogs at the same time, the problem appears. ONLY THE PLAYER ON THE FIRST THREAD SOUNDS AND THE OTHER ARE SILENT. I did try to fix it, but nothing changed. Please give me some advices for this. Thank you very much (^__^)

Problems
nepobunceno

14:42 18 Apr '06

I have tried this program, and it seems simple enough. But there is one little problem, and I am not sure what the error could be. When I open the file, nothing appears to be happening. I have tried the program with other computers that don't have the codecs, and a white with red screen appears letting me know that I don't have the necessary codecs. So I'm not sure what the problem could be.

Thanks for your help

how to play the mp3 song in the required output device, is there any function to specify the output device id for mp3
Farooq kotwal

2:05 22 Jun '05

Plz can any one tell how to play the mp3 song in the required device when there are more than one sound card present in the system. For wav songs when we play the song we can specify the device id in to which the wave song must be played. Is there any such mechanism for playing the mciwnd songs.... Farooq Kotwal

Hi there,

thanks for the good article. I receive building errors though:

Elsa error LNK2019: unresolved external symbol _MCIWndRegisterClass referenced in function "public: bool __thiscall CElsaDlg::startBildspel(void)" (?startBildspel@CElsaDlg@@QAE_NXZ)

Elsa fatal error LNK1120: 2 unresolved externals

Does anyone have a clue what I am doing wrong here?

Thanks,

Did you link with VFW32.Lib? What Visual Studio version are you using?

Adding a volume button
SaraMalkaW

16:05 9 Jan '05

Hi! I downloaded the player and I am trying to add volume buttons in MFC. I added the buttons and functions with the class wizard in Visual C++, but my functions are not working. Here is my code:
void CAVIPlayerDlg::OnVolumeDown()
{
long vol;
vol = MCIWndGetVolume(m_Video);

vol-=250;
MCIWndSetVolume(m_Video,vol);

}

void CAVIPlayerDlg::OnVolumeUp()
{
long vol;
vol = MCIWndGetVolume(m_Video);

vol+=250;
MCIWndSetVolume(m_Video,vol);

}
It runs, but the call MCIWndGetVolume(m_Video) returns 0 each time, and the volume isn't affected. Any ideas?

Forget the GetVolume function, put a variable with the desired volume into your application and use that instead.

I'm having trouble with the m_Path, says it is an undeclared identifier. I can't find anywhere in your program where you identify m_Path. It also says something about binary '=' problem with the m_Path. xero

MMSYSTEM 296 ERROR while play mp3 file
chuit

11:28 5 Jan '04

Hi,
First of all, I would like to say that this simple MP3 Player is good, but I have a problem to use it on some PC. I can compiled and
play the mp3 file well in my original Windows OS - 98.
However, when I try to move the exe file to another PC
with Windows 98 as well, the application cannot play any
mp3 file. It always pops up the MMSYSTEM error, as shown
below:
"MMSYSTEM296 The file cannot be played on the specified
MCI device. The file may be corrupt, or not in the
correct format."

I tried many ways, such as copy a good mp3 file to the PC,
change the mp3 registter key, run the mmsys296.exe, etc,but none of them work.

Any idea how to fix this problem?
