I've been using mciSendString Lib "winmm.dll" forever and all of sudden it
stopped playing MP3s. I keep on getting the same error and no playback: A
problem occurred in initializing MCI.

Any help is greatly appreciated.

Hi, Gordon

Did the problem occur on the same machine, or when your ran the application
on a different machine?

I spoke to the tech lead of our multimedia team, and he suggested that you
check to see if the file mciqtz.dll is on your system. If not, you should
download the latest media player from Windows Update, which should correct
the problem. If not, please reply here with more information and I will
expedite.

Hi,

Same machine.
I performed a search for "mciqtz.dll" and it couldn't be found. I did a
Windows Update and re-installed wmp 9, and still, file "mciqtz.dll" could
not be found.

Thanks

Hi, Gordon

My mistake. I should have typed mciqtz32.dll, not mciqtz.dll.

I apologize for my error. I assume that updating MP9 did not resolve the
problem.

I was not able to reach my MM contact. I will keep trying and let you know
what he says.

Hi, Gordon

I have created an escalation and assigned it to the tech lead of the MM
team. He should respond to your issue here. If you do not receive a
response by close of business, Pacific time, on Wednesday, please post here
and I will expedite.

Hi Gordon,

1. What OS do you see the problem on?
2. What is the version and date of mciqtz32.dll on your system?
3. You mentioned that this used to work on your system. Do you recall any
changes you made that might have caused the MP3 playback to fail?

I am including a MCI sample that plays MP3 files. Can you run this on you
system and let me know if it works or not. The MP3 file name is hardcode in
the call mciPlayMP3.

Thanks,

I don't know VC, I tried pasting the code you provided in a VC project but
couldn't get it to compile.
Do you have a VB Sample?

Thanks

Hi Gordon,

Can you provided more details as to which call failed. Was the sound device
being used by any other process when this call was made.

I still haven't received a reponse from you to my original questions. I am
including them below once again. Kindly let me know the answers to the
questions below

1. What OS do you see the problem on?
2. What is the version and date of mciqtz32.dll on your system?
3. You mentioned that this used to work on your system. Do you recall any
changes you made that might have caused the MP3 playback to fail?

Thanks,

The following C code works when I want to play an mp3 from
disk:

mciSendString("open my.mp3 type mpegvideo alias test" ...);
mciSendString("play test" ...);

But it fails if I try this:

mmioInstallIOProc(mmioFOURCC('M', 'E', 'Y', ' '),
(LPMMIOPROC)IOProc, MMIO_INSTALLPROC | MMIO_GLOBALPROC);
mciSendString("open test.MEY+ type mpegvideo alias
test" ...);
mciSendString("play test" ...)

IOProc is the exact same as defined in article 155360 from
the KB, and I made sure to assign the file data and size
in the globals used in the example. I put a breakpoint at
the very beginning of IOProc, and it was never hit in the
debugger. It will stop at the breakpoint; however, if I
change "mpegvideo" to "avivideo".

Any ideas?

My player gets the same error if there is an embedded jpg.

Who on Earth had that idea?

I'll make some changes to identify those files and convert them so there is no JPG.
