For those who struggle to compile this example project as .zip does not have any instructions.
My system: WinXP, Qt4.6.2 for VisualStudio, MS Visual Studio C++ 2008 Express Edition
1) I edited Player.pro file, added the following lines to keep release folder clean after compilation.
OBJECTS_DIR = obj
MOC_DIR = moc
2) Create platform dependent makefiles
Create the following bat script, save to project folder, run it
set path=%path%;C:\Qt\4.6.2\bin
qmake -makefile
3) Compile a project
Create the following bat script, save to project folder, run it
call "C:\Program Files\Microsoft Visual Studio 9.0\VC\bin\vcvars32.bat"
nmake release
pause
4) Copy images folder, run an app
Copy images folder to release/images, run release/Player.exe application
WARNING: bool Phonon::FactoryPrivate::createBackend() phonon backend plugin could not be loaded
I used mingw32+QT4.5.0,can you help me how to fix this problem.
First you cannot use phonon with mingw32. You have to build Qt from the source with visual studio 2008 express edition (free from microsoft).
You can look on google on how to build Qt with VS or you can read this : (its a french website translated to english)
Good luck

I think that phonon module is not installed with Qt, you need to recompile it. type ./configure -v or configure.exe -v to see if the phonon module is available. If not you need to install the backend and it depends on your OS. take a look at this overview:
http://doc.trolltech.com/4.4/phonon-overview.html
and http://www.qtcentre.org has a lot of help too.
Good luck !
I installed Phonon but still give these errors
