[Mingw-cross-env-list] Does QtMultimedia work for anyone?

[Nikos Chantziaras]

Since I'm not able to figure out how to get gstreamer to work with MXE, 
I'm now trying Qt5 and its multimedia module.  So I've build that and 
then compile the two example programs that play video.  Neither one 
works.  The error message says:

  The QMediaPlayer object does not have a valid service.
  Please check the media service plugins are installed.

What is missing?  From the build log of "make qtmultimedia" one would 
guess that it's build with DirectShow support:

  Checking for openal... no
  Checking for directshow... yes
  Checking for wmsdk... no
  Checking for wmp... no
  Checking for wmf... no
