set raw data buffer to QMediaPlayer

I want to get a screen shot of the widget application and then set its raw data buffer to QMeidaPlayer with setMedia(). If anyone tried this before, I would thank if you tell me how to do that:

Code:

---

QPixmap originalPixmap = QPixmap::grabWidget(this);
 
    QImage *image = new QImage(originalPixmap.toImage());
 
    QByteArray ba;
 
    QBuffer buffer(&ba);
 
    buffer.setBuffer(&ba);
 
    buffer.open(QIODevice::WriteOnly);
 
    image->save(&buffer); // writes image into ba in PNG format
 
    image->save("/home/saman/Desktop/myImage", "PNG");
 
    mediaPlayer.setMedia(QUrl::fromLocalFile("/home/saman/Desktop/png/images08.jpeg")); //I want this to read from raw data
 
    mediaPlayer.play();

---

I note again, what i have done is to receive the image, SAVE it, and then read from it. However, I would like to ask you how to read raw data directly without saving it into media player.

Code:

---

// saving
    counter = 1;
    image.save("/home/saman/image", "JPG");
    counter = 0;

---

somewhere else, reading

Code:

---

if(counter == 0)
    {
        mediaPlayer.setMedia(QUrl::fromLocalFile("/home/saman/image"));
        mediaPlayer.play();
    }

What I did is to use:

Code:

---

QMediaResource rsrc(QUrl::fromUserInput(image.text()));
    QMediaContent ctnt(rsrc);
    mediaPlayer.setMedia(ctnt);
    mediaPlayer.play();

but this, does not show anything. I need help over here, give me advice please.
