  Which components are needed for WAV/MP3 over MCI?         


Author: Benjamin Grund
Date: Feb 11, 2008 09:06

Hello,

I am trying to write an application that plays WAV and MP3 files through
MCI. On my developer machine everything works fine, but on the target machine
running XP embedded the application creates an MCI 263 error if I try to open
a WAV or MP3 file.

The following Components are already included in my XPe image:

- Acm Core Codecs
- Primitive: Winmm
- Kernel Audio Support
- Legacy and Plug and Play Audio Support
- Microsoft Audio Compression Manager (MME Core)
- MCI Support
- DirectShow MCI

Which components do I have to add to my configuration to get my application
to work?

Thanks in advance,
Benjamin

  I/O access suddenly stopped working

Hello,

I have an application which require I/O access, to start and refresh
the watchdog chip. I have been using the inpout32.dll (www.lvr.com)
driver to get to access the I/O. Everything were fine under EWF, and
also a non-administrator account. But that is not the case under FBWF;
I simply cannot get the watchdog to trigger a computer restart under a
non-administrator account. The interesting thing is when I load the
same application under administrator account, everything worked as
expected.

I am unsure why the application misbehave under the non-administrator
account on FBWF. Can anyone tell me whether there is any security
policy being changed under FBWF and/or Feature Pack 2007?

Any help will be appreciative. Thank you.
