Qt5 Multimedia Problem

[goocreations]

Solved the problem by not using Windows, but Ubuntu. Which version are you using Qt5? Alpha? Beta? Maybe it will be fixed in the final release.

Qt 4.8.1

Same problem here: http://qt-project.org/forums/viewthread/22018/

I tried to run the new Media Player exmaple with Qt5 on windows xp and got exactly the same error:

defaultServiceProvider::requestService(): no service found for – “org.qt-project.qt.mediaplayer”

Just guess. Could you check your Qt installation directory in plugins/mediaservice folder for wmfengine(d).dll? As I understand QMultimedia module relies on Windows Media Foundation library internally to play video on Windows.
In my installation I also have qtmedia_audioengine.dll.

I have these files under:

C:\QTSDK_5\5.0.0-beta2\msvc2010\plugins\mediaservice

There is:

qtmedia_audioengine.dll
qtmedia_audioengined.dll
qtmedia_audioengined.pdb
wmfengine.dll
wmfengined.dll
wmfengined.pdb

Have you setted up QTDIR and PATH env variables?

[Vaido]

No, I am using the binary package where you don't have to set any variables..or am I wrong here?!

[INeedMySpace]

Even in binary installation if you run examples from console you should those variables setted up for you plugins to be found.
