So, I would like to know if anyone knows about QML Media Player CPU performance or someone can give a tip in order to use properly these QML component or to reduce CPU rate, or let me know if that is a QML limitation.

Environment:
SO: Windows
QT: 5.4
Kit: Desktop Qt 5.4 MSVC2013 32bit

QTWidget Code:
@ player = new QMediaPlayer;
player->setMedia(QUrl::fromLocalFile("file.mp4"));

playerWidget = new QVideoWidget;
player->setVideoOutput(playerWidget);
playerWidget->show();

player->play();@

QML Code:
@MediaPlayer {
id: playMusic
source: "file.mp4"

}

VideoOutput {
    anchors.fill: parent
    source: playMusic
}

Component.onCompleted: { playMusic.play() }@

Many thanks.
