I have read the Win32 documentation in Graphics and Multimedia section, Core Audio Programming Guide.
There is no simple example to load mp3 file and play it using Win32 API in the documentation, as always.
In short, I am looking for a simplest approach for loading an mp3 file and play the sound using Win32 API.
If possible, I need to do pause, track the progress, stop, skip or back at specified position.
Note: Simple here doesn't mean easy, it can be a complex thing, on the most basic level.
One of the simplest ways is with MCI, like mciSendString
Is mciSendString can do all audio control? This includes:
Edit: I still don't have an idea to use it, can you please provide an example?
There is an example for mciSendString in the link that I provided (see my answer).
mciSendString cannot pause, move,.. the mp3 file. Have a look at mciSendCommand function.

Yes, with MCI commands
But if you want to make a sort of Media Player, you can copy/adapt one of the MS players from the SDK, like
DShowPlayer
or
MFPlayer2
or you can embed directly the WMP control (with ATL for example ("AtlAxWin"))
mciSendString cannot pause, move,.. the mp3 file.
All commands work.
For example, this opens, plays and pauses a MP3 file :
open "test.mp3" type MPEGVideo alias MediaFile
play MediaFile
pause MediaFile
Thank you so much for the example. @Castorix31
Is mciSendString process-dependent?
For example, if I open an audio file in different process and play it, then stop it on different process, will it work?
Here is my first try, but it nothings play:
#ifndef UNICODE
#define UNICODE
#endif
#include <Windows.h>
#pragma comment(lib, "Winmm.lib")
int WINAPI wWinMain(HINSTANCE, HINSTANCE, PWSTR, int) {
mciSendStringW(
L"open \"F:\\bluetropics\\reflect.mp3\" type MPEGVideo alias reflectMusic",
NULL,
0,
NULL
);
mciSendStringW(
L"play reflectMusic",
NULL,
0,
NULL
);
return 0;
}
Anything I do wrong here?
Edit: PlaySound() seems to be work, however, It is limited to waveform audio files only, 41MB file for a 4 minute song is ridiculous. It is also lacks of control (move, stop, pause, etc)
No, the same code with one of my .MP3 works for me (tested on a button click)
You can try mciGetErrorString with the return code of mciSendString if != 0
All mciSendString returns 0, there is no errors.
Test in a Button click
In your test, the program ends immediately...
It works perfectly! Thank you so much @Castorix31
Hello,
have a look at this: simplest-way-to-play-mp3-from-visual-c
Regards, Guido
Use MCI to control the audio device. For pause, move,... have a look at mciSendCommand

Thank you so much for the response, @Guido Franzke
I'll note that
