QMediaPlayer - "Internal data flow error."

[redevil5k]

Hello.

I am trying to read a video input in Linux (Ubuntu 16.04 LTS) using QMediaPlayer. The video is read and show fine. However after some random time i constantly get this error:
Error: "Internal data flow error." and my video stops showing. By opening the video again it resumes as usual.

The code I used to confirm the error:

MainWindow::MainWindow(QWidget *parent)
    : QMainWindow(parent)
    , ui(new Ui::MainWindow)
    , player(0, QMediaPlayer::VideoSurface) //QMediaPlayer
    , videoItem(0) // QGraphicsVideoItem
{
    ui->setupUi(this);

    videoItem = new QGraphicsVideoItem;
    QGraphicsScene *scene = new QGraphicsScene(this);
    ui->graphicsView->setScene(scene);
    scene->addItem(videoItem);
    player.setVideoOutput(videoItem);
    player.setMedia(QUrl("v4l2:///dev/video0"));
    player.play();
}

What could be causing this error and how can I resolve it without automatically calling the video on QMediaPlayer::StoppedState?
