QMediaPlayer QML Binding Issue

[mkocabas]

I'd like to implement a QMediaPlayer video stream that will be shown on QML. I tried to extend the QMediaPlayer class and created below MyMediaPlayer class. I instantiate this class in my main.cpp file to show it on GUI. Even though there are no errors, the video isn't visible on the QML window. Where is my fault?

mymediaplayer.cpp

#include "MyMediaPlayer.h"

MyMediaPlayer::MyMediaPlayer(QObject* parent, Flags flags): QMediaPlayer(parent, flags)
{
}

void MyMediaPlayer::setVideoSurface(QAbstractVideoSurface* surface)
{
    qDebug() << "Changing surface";
    m_surface = surface;
    setVideoOutput(m_surface);
}

QAbstractVideoSurface* MyMediaPlayer::getVideoSurface()
{
    qDebug() << "Surface Got";
    return m_surface;
}

mymediaplayer.h

#ifndef MYMEDIAPLAYER_H
#define MYMEDIAPLAYER_H
#include <QMediaPlayer>

class MyMediaPlayer: public QMediaPlayer
{
    Q_OBJECT
    Q_PROPERTY(QAbstractVideoSurface* videoSurface READ getVideoSurface WRITE setVideoSurface )

public:
    MyMediaPlayer(QObject * parent = 0, Flags flags = 0);

public slots:
    //virtual void play(const QString& strFile);
    void setVideoSurface(QAbstractVideoSurface* surface);
    QAbstractVideoSurface* getVideoSurface();

private:
    QAbstractVideoSurface* m_surface;
};

#endif // MYMEDIAPLAYER_H

main.cpp

 MyMediaPlayer* player = new MyMediaPlayer();


engine.rootContext()->setContextProperty("mediaplayer", player);

QQuickView view;
view.engine()->rootContext()->setContextProperty("mediaplayer", player);

player->setMedia(QUrl(QStringLiteral("qrc:/1.mp4")));
qDebug() << "media set";
player->play();
engine.load(QUrl(QStringLiteral("qrc:/main.qml")));

main.qml

VideoOutput {
        z: 1000
        id: videooutput
        width: 320
        height: 240
        source: mediaplayer
    }
