play audio file

Question

Hello,

I've read some posts regarding issues of playing audio on the Win. mobile devices but i couldn't activate the any sound file on my PPC (WM5\6)

I've tried using the PlaySound API but it donesn't work:

if (!PlaySound (L"\\Windows\\Rings\\Ring-Innovation.wma", NULL, SND_FILENAME | SND_ASYNC))
{
...
}

And i always get into the "if" block, can someone help please?
Thanks.

Hi,

I need API thta can run on both WM5 and WM6 and according to some posts this function (sndPlaySound) can run only on WM6.
Also, if possible, i want to use C++ only.
I already managed to play a WAV file using PlaySound but i want to play WMA\MP3 as well and i didn't manage to do so yet.
Thanks.

I really hate to repeat myself so I'll just link You: http://social.msdn.microsoft.com/Forums/en-US/windowsmobiledev/thread/0cb2fedc-9d75-4e6f-b7fb-d914c58e2c9f

In that discussion I gave a simple example of how to play any WMP supported sound.

Works on WM3+ (but <WM5 requires older WMP version).

Answer 4

Hello,

I've read that i need to include a header file (wmp.h) and in order to do so i need to download WMP SDK, is there any preffered WMP SDK version
that i should use?

Answer 5

WMP 10 is preferred up to WM 6.5.

For WM3SE and older use WMP 9.

Answer 6

Hi,

I've downloaded WMP 10 as you suggested and i encounter 2 problems:
1) The function put_URL returns S_FALSE
2) If i try to release the controls, settings and player i get an unexpected exception which i can't find its source but i've noticed
that if i don't release these objects it doesn't occur.

Can you please advise?
Thanks.

Answer 7

put_URL will return false in two conditions:

1) Invalid path specified -> using '\' instead of '\\' or You're referning to a relative path (path must be absolute 4ex. L"\\Program Files\\My app\\test.mp3")

2) You have not initialized it's class/interface. Check if You're retriving a valid pointer.

Answer 8

Hi,

I've checked again the code and i didn't find any problem:
1) I used the full path including '\\' and not '\'
2) The IWMPPLAYER pointer is valid.

I've tried to play both wav and wma files and none of them worked.

 

Answer 9

You're developing for PPC WM5+ or other?

Please show me Your code (include also header names).

Answer 10

Hi,

Here is the code i'm using for PPC WM5 and WM6:

#include
 
 <wmp.h>

IWMPPlayer *player = NULL;
IWMPControls *controls = NULL;
IWMPSettings *settings = NULL;
CoInitializeEx(NULL, COINIT_MULTITHREADED);
if (CoCreateInstance(__uuidof(WindowsMediaPlayer), 0, CLSCTX_INPROC_SERVER, __uuidof(IWMPPlayer), (void **)&player) == S_OK)
{
	HRESULT res = player->get_controls(&controls);
	res = player->get_settings(&settings);
	//res = settings->put_autoStart(TRUE); 
	res = player->put_URL(L"\\TestApp\\snd.wav");
	res = controls->play();
	res = S_FALSE
}

player->close();
controls->Release();
settings->Release();
player->Release();
player = NULL;
CoUninitialize();

By the way, should ia make any difference if i'll run it on SP WM5 \ WM6?
Thanks for the help.

Answer 11

He,he,he. You're trying to play wav files :D :D. Try to play mp3 or wma and it will be working.

For wav files You need to use coredll method called - sndPlaySoundW (same as PlaySound but is found on every known WM OS (Win CE also))

Answer 12

Hi,

I also tried to play wma file (which is one of the OS rinings file) and it didn't work either

Answer 13

Strange, because I know it works. Try on emu or other device.
