Video Avi and QT

Hi,
I tried to play a vedeo Avi in Windows XP using QT4.

My code is very simple:

QString fileName = QFileDialog::getOpenFileName(this, tr("Open Movie"), QDir::homePath(), NULL);
Phonon::VideoPlayer *player = new Phonon::VideoPlayer(Phonon::VideoCategory, ui->graphicsView);
player->play(fileName);

I have no errors, but starting the program nothing happens, the graphicsView remains empty and the video does not start.

On Windows XP I loaded the video codec, in fact the video start normally using any video player.

This won't answer your question but since phonon is not supported anymore, have you consider the idea of using the module Multimedia of qt mobility ?
There are some exemples here :

why should the graphics view show anything? :confused:

If you have a problem, CUT and PASTE your code. Do not retype or simplify it. Give a COMPLETE and COMPILABLE example of your problem. Otherwise we are all guessing the problem from a fabrication where relevant details are often missing.

I have already read the documentation on qt-project.org.

In my code, I opened a video stream and redirected it on the GraphicsView. So I should see the video in the GraphicsView. There are more examples like my code, I don't see where is the problem.
