Question

我想在Qt 4.7.0中创建视频播放器。我找到了Phonone lib。我在documetation中找到了例子，但是如果我接受了我的崩溃

代码：

MainWindow::MainWindow(QWidget *parent) :
        QMainWindow(parent),
        ui(new Ui::MainWindow)
{
    ui->setupUi(this);

    VideoPlayer *player = new VideoPlayer(VideoCategory);
    player->setFixedSize(QSize(400,300));
    player->move(1280-400,0);
    player->show();
    connect(player, SIGNAL(finished()), player, SLOT(deleteLater()));
    player->play(MediaSource(QString("C:\\vid.flv")));

}

错误：

debug/mainwindow.o: In function `MainWindow':

也许有人知道它是什么？
