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.

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?

[A Former User]

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

[A Former User]

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