Hello, I am trying to acomplish this thematic of playing a MP3 sound file that is a resource in memory. I'm really not interested about
playing it from a file because that I already did. I was looking some codes over the net but some of them refer to using some libraries like BASS or FMOD or similar.. I was trying to do this using the normal Windows API, but it seems not posible or I don't know it
If anyone here knows, can kindly tell me how to do this ?
I show you what I was trying the latests...
see this link

I modified that function, after reading some information on it. This information:

it seems that developers of this "seemed" to have left a hidden way of playing the mp3 from a buffer in memory, or maybe is not like this,
but there is a flag called MCI_WAVE_OPEN_BUFFER for using when calling mciSendCommand with MCI_OPEN , and it really isn't working for me
these structures are for reference
I was using this function like this
help?

Code:

mciOpenParms.dwCallback=0L;
mciOpenParms.wDeviceID=0;

mciOpenParms.lpstrDeviceType = (unsigned short*)MCI_DEVTYPE_WAVEFORM_AUDIO;
mciOpenParms.lpstrElementName = L"";
mciOpenParms.dwBufferSeconds = BufLen;

dwReturn = mciSendCommand(0, MCI_OPEN,

,
(DWORD)(LPVOID) &mciOpenParms);
if (dwReturn)
{
MessageBoxA(0,"RETURN BAD 1",0,0);
// Failed to open device. Don't close it; just return error.
return (dwReturn);
}
// The device opened successfully; get the device ID.
wDeviceID = mciOpenParms.wDeviceID;
// Begin playback. The window procedure function for the parent
// window will be notified with an MM_MCINOTIFY message when
// playback is complete. At this time, the window procedure closes
// the device.
mciPlayParms.dwCallback = (DWORD) hWndNotify;
dwReturn = mciSendCommand(wDeviceID, MCI_PLAY, MCI_NOTIFY,
(DWORD)(LPVOID) &mciPlayParms);
if (dwReturn)
{
MessageBoxA(0,"RETURN BAD 2",0,0);
mciSendCommand(wDeviceID, MCI_CLOSE, 0, NULL);
return (dwReturn);
}
return (0L);
}I was using this function like this
Code:
unsigned int BLen = ResourceMP3ToBuffer(IDR_MP31);// mp3 as resource id
if(BLen)
{
if(bMP31)// buffer containing resource
{
DWORD dwret = playWAVEFile(hDlg, (unsigned short*)bMP31, BLen);
}
else
{
MessageBoxA(0,"buf not loaded",0,0);
}
}
else
{
MessageBoxA(0,"no size",0,0);
}
