Deploying Qt app with QtMultimedia on Linux

问题

I tried to deploy an application Qt (5.3) on Linux (Ubuntu 14.04) which use QtMultimedia I have first deployed a simple application (Hello World) to understand. I have had no problem ro run the application on Pc without install Qt. In the same way, I have tried to desploy my whole app but I have a problem when I want execute my application :

QQmlApplicationEngine failed to load component
qrc:/main.qml:3 module "QtMultimedia" is not installed

I have understand the problem comes to QtMultimedia but I don't find which library I have forgotten. I have the tree for my project deployment :

- myApp/.
    - libs
        - libQt5Multimedia.so.5.3.1
        - libQt5MultimediaQuick_p.so.5.3.1
        - libQt5MultimediaWidgets.so.5.3.1
        - ...
    - myApp
    - Makefile
    - ...

Of course, my app run correctly on machine (ubuntu 13.10). My app.pro :

TEMPLATE = app

QT += qml quick multimedia


SOURCES += main.cpp \
    datacube.cpp

RESOURCES += qml.qrc \
    img_interface.qrc \
    img_contenu.qrc \
    media.qrc

# Additional import path used to resolve QML modules in Qt Creator's code model
QML_IMPORT_PATH =

# Default rules for deployment.
include(deployment.pri)

HEADERS += \
    datacube.h

Thank you for your help
