I've got some problems with the object VideoOutput... when I use it, for example like that :

import QtQuick 2.0
import QtMultimedia 5.0

Rectangle {
width: 800
height: 600
color: "black"

MediaPlayer {
    id: player
    source: "file://video.webm"
    autoPlay: true
}

VideoOutput {
    id: videoOutput
    source: player
    anchors.fill: parent
}

}

I've got this error :

/home/myname/Qt/5.3/gcc/bin/qmlscene: symbol lookup error: /home/myname/Qt/5.3/gcc/qml/QtMultimedia/../../lib/libQt5MultimediaQuick_p.so.5: undefined symbol: _ZN11QCameraInfoC1ERK10QByteArray
/home/myname/Qt/5.3/gcc/bin/qmlscene exited with code 127

Thanks in advance,
