Very confused About Qt5 and Phonon/QtMultimedia

[aguayro]

Hi, i've been reading and googling about Phonon and Qt5, and i'm very confused.
Do i need to install any module? Where can i download it? have i to compile it?
Can't find clear information about it. Some places says it's no more included in Qt5, but i seem to have the headers if i type <QtMultimedia> in Qt Creator,... but, i get error when compiling:

error: C2079: 'videoPreview' uses undefined class 'QVideoWidget'

error: C2079: 'videoPreview' uses undefined class 'QVideoWidget'

QVideoWidget is part of QtMultimedia module in Qt5. Remember to enable the module in the project file.

Oh thanks!! Always saving my ass, i'm going to build a monument in your name

EDIT: Mmm, QT += multimedia doesn't work, any sugerence?

EDIT2: ok, this doesn't work:

QT += core gui widgets network multimedia multimediawidgets

QT += core gui widgets network multimedia multimediawidgets

This works:

QT += core gui widgets network
QT += multimedia multimediawidgets

QT += core gui widgets network
QT += multimedia multimediawidgets
