Window 下 Qt5 使用QMediaplayer 进行视频播放 流播放问题

int main(int argc, char *argv[])
{
QApplication a(argc, argv);

   QWidget *widget = new QWidget;
    widget->resize(400, 300);   //

    QVBoxLayout *layout = new QVBoxLayout;
    QMediaPlayer* player = new QMediaPlayer;
    QVideoWidget* vw = new QVideoWidget;

    layout->addWidget(vw);
    widget->setLayout(layout);

    player->setVideoOutput(vw);

    QFile file("123.mp4");
    if(!file.open(QIODevice::ReadOnly))
        qDebug() << "Could not open file";

    player->setMedia(QUrl::fromLocalFile("123.mp4"));
    player->play();
    vw->show();

return a.exec();

}
