[Qt-interest] Phonon within browser plug-in

[gordon at gordonswelt.de]

Well, i am starting to get nuts on this.
I already posted to five different forums and did not get any useful
information.

My problem:

I'm currently working on an application i'll use within my thesis work.

Therefore, i plan to have a 'media player' like application which is to
be run as a browser plugin.

So far, so good.

Implementation of simple phonon support worked well within a simple
window-based application, but if
i try to use those phonon modules within a browser plugin stub, nothing
happens.

For the browser plugin i used the qtbrowserplugin sources.

This is a snippet of the phonon code i use:

video = new Phonon::MediaObject(this);
QString filename = "./test.avi";
video->setCurrentSource(filename);
videoWidget = new Phonon::VideoWidget(this);
Phonon::createPath(video, videoWidget);
Phonon::AudioOutput *audioOutput = new
Phonon::AudioOutput(Phonon::VideoCategory, this);
Phonon::createPath(video, audioOutput);

connect(video, SIGNAL(stateChanged(Phonon::State, Phonon::State)), this,
SLOT(stateChanged(Phonon::State, Phonon::State)));


When i run the plugin, everything seems fine, but the phonon module
never overcomes the 'loading' state.

I tried for debugging purposes setting the name of the media to be
played back to a file that doesn't exist, so phonon whould switch to a
Phonon::ErrorState, but it does not. It just keeps sitting in the
Phonon::LoadingState, forever.

O/S is Windows XP, Qt4.5.0-rc1 (and formerly 4.4.3)  is used

The same piece of code works like a charm within a simple window
application.

Can anyone help me out on this ?
