[Qt-qml] Audio and Video

[Sreedhar]

Hi,

I am totaly new to Qt and Qt Creator.
With my past exp with Adobe products i developed few QML 
Objects using Qt Creator 1.3.81.

Now i plan to Create Audio and video Player with QML Elements of 
Qt Creator 1.3.83.

When i try the below example 
http://doc.qt.nokia.com/4.7-snapshot/qml-audio.html

I get the error saying

defaultServiceProvider::requestService(): no service found for 
-"com.nokia.qt.mediaplayer"

My Qt version is 4.7 Beta1

And it is a binary version only.

My OS is window XP

And i compile the files in Qt Creator 1.3.83.

And once again i will like to tell you that i am new to Qt creator

If you can explain me it would be great.
