Generic Music Player

I saw @Shadow` 's hack and saw that it had the ability to be able to play music. The only downside was that it only worked with WAV files and had to be in a specific folder so I decided to tackle this problem myself and write a small class for it. With this class, you will be able to play MP3 files and other formats supported by the computer as long as you have the codecs available for it. I've also tested it with FLAC and WAV, they work fine. This class is mainly powered by the MCI API from Microsoft. You can enter in relative/partial paths, like "Music" and it will find all files in the "Music" folder next to the injected DLL. You can also put in absolute paths like "C:\Music Stuff" and it will search that directory.

Also if you noticed that I used, TCHAR, LPTSTR and _T alot, well that's because I wanted to add support for both ANSI and Unicode depeding on the Character Set that's been used on the current project. Also note that the class is static, meaning you can only have 1 instance of it in every application or DLL.

I should also mention that SetVolume uses a value between 0 and 1000, eg. 0 = 0% and 1000 = 100%. The same thing applies to the Volume variable which tells the current volume level. GetCurrentPosition and SetCurrentPosition use millisecond values for their positions.

Here's a little "Demo DLL" source that you can try out to test some of the class' features.

Code:

#include <Windows.h>
#include "player.h"

DWORD WINAPI Main(LPVOID)
{
	unsigned int currentEntryIndex = 0;

	// Find all .mp3 files inside the Music folder next to the DLL.
	MusicPlayer::PopulateMusic(_T("Music"), _T(".mp3"));

	// Check if there were any .mp3 files found.
	if(!MusicPlayer::Entries.size()) return 0;

	while(true)
	{
		// If no song is playing, play one.
		if(!MusicPlayer::IsPlaying())
		{
			// Check that we've played all songs.
			if(currentEntryIndex < MusicPlayer::Entries.size())
			{
				// Play the next song available.
				MusicPlayerEntry* entry = MusicPlayer::Entries[currentEntryIndex++];
				MusicPlayer::PlayMusic(entry);

				// Display song information.
				TCHAR buffer[255];
				TCHAR formattedTime[20];
				// Convert the milliseconds to minutes and seconds.
				MusicPlayer::FormatMilliseconds(MusicPlayer::LengthMilliseconds, formattedTime, 20);
				_stprintf_s(buffer, _T("Current song is: %s\nLength: %s"), entry->SongName, formattedTime);
				MessageBox(NULL, buffer, _T("Information"), MB_OK);
			}
			else
			{
				// Exit.
				MessageBox(NULL, _T("All songs have been played!"), _T("Done"), MB_OK);
				break;
			}
		}
		Sleep(1000);
	}

	return 0;
}

BOOL APIENTRY DllMain(HMODULE hDll, DWORD dwReason, LPVOID lpReserved)
{
	switch(dwReason)
	{
	case DLL_PROCESS_ATTACH:
		DisableThreadLibraryCalls(hDll);
		CreateThread(NULL, NULL, Main, NULL, NULL, NULL);
		break;
	case DLL_PROCESS_DETACH:
                // Cleanup stuff here, only do it when the player is no longer needed.
		MusicPlayer::Cleanup();
	}

	return TRUE;
}

I've attached the built Demo DLL which you can inject into any process and mess around with.

Download & Thanks

Thanks man...

Great job bro.

This is great work. I was personally trying to get WinAMP integration working since I couldn't find any info on iTunes.

This is a good thing to settle to if everything fails. Either way, its good work

Well Done , thanks

Meennn!!!

Cool post.

Well, Hybrid GUI released by EvilNess back in June 2010 has more control features.

Code:

//control functions
    void        Play( void ){ Send_Command( WINAMP_BUTTON2 ); }
    void        Pause( void ){ Send_Command( WINAMP_BUTTON3 ); }
    void        Stop( void ){ Send_Command( WINAMP_BUTTON4 ); }
    void        Next_Track( void ){ Send_Command( WINAMP_BUTTON5 ); }
    void        Previous_Track( void ){ Send_Command( WINAMP_BUTTON1 ); }
    void        Repeat_Toggle( void ){ Send_Command( WINAMP_BUTTON_REPEAT ); }
    void        Shuffle_Toggle( void ){ Send_Command( WINAMP_BUTTON_SHUFFLE ); }
    void        Seek_Track_Position( int m_iPosition ){ Request_Command( m_iPosition, IPC_JUMPTOTIME ); }
    void        SetVolume( int m_iVolume ){ Request_Command( m_iVolume, IPC_SETVOLUME ); }
    void        IncreaseVolume( void ){ Send_Command( WINAMP_VOLUMEUP ); }
    void        DecreaseVolume( void ){ Send_Command( WINAMP_VOLUMEDOWN ); }
    void        Goto_Track_Begin( void ){ Send_Command( WINAMP_BUTTON1_CTRL ); }
    void        Goto_Track_End( void ){ Send_Command( WINAMP_BUTTON5_CTRL ); }
    void        Goto_TrackByIndex( int index ){ Request_Command( index - 1,IPC_SETPLAYLISTPOS ); }
    void        FastForward( void ){ Send_Command( WINAMP_FFWD5S ); }
    void        FastRewind( void ){ Send_Command( WINAMP_REW5S ); }
    void        LoadPlaylist( char *m_szDirectory, char *m_szFile );

Lol I beg to differ, there have been extremely sexy menus in the past 2 years.

Hybrid GUI is only for Winamp though, master131's class lets you listen to music from any folder on your computer.

Woah fck yeah !!! Thanks for sharing this code brah! of course if it works you get da credits :P

you guys need to check out the BASS library, why better sound and support multiple codec straight out the box without using windows media player control.

I've also heard FMOD is pretty nice.

Windows Media Player Control? What? MCI != WMP

It's not even a control. I'm well aware of the BASS library, I've used it in a .NET application to play XM files. Anyway, adding alot of extra DLLs just to play music is going to be a hassle for people if it's used in a hack.

FMOD is for playing .mod files not mp3/mp4/ogg/ect..

THanks Master!
