Hi everyone, recently qt 4.7.0 tp has released and it intrtroduces a lot of new stuff. One thing i'm really exited about is that Qt now supports video playback natively by QMultimedia Module.

However, when i embed a QVideoWidget which connects to a QMediaPlayer into QGraphicsScene, the video just do not show up in the QGraphicsView while i do can hear the sound in the video?

Does anyone have a solution? Thanks a lot

the following is a part of my code:

Qt Code: 
  1. class MovieInfoViewer : public QMainWindow
  2. {
  3.     Q_OBJECT
  4.  
  5. public:
  6.     MovieInfoViewer(QWidget *parent = 0, Qt::WFlags flags = 0);
  7.     ~MovieInfoViewer();
  8.  
  9. private:
  10.     Ui::MovieInfoViewerClass ui;
  11.  
  12.     QGraphicsScene* pMainScene;
  13.     QVideoWidget* pBackGroundVideoWidget;
  14.     QMediaPlayer* pBackGroundVideoPlayer;
  15. };

  2.     : QMainWindow(parent, flags)
  3. {
  4.     ui.setupUi(this);
  5.  
  6.     pMainScene=new QGraphicsScene();
  7.     pBackGroundVideoWidget=new QVideoWidget();
  8.     pBackGroundVideoPlayer=new QMediaPlayer();
  9.  
  10.     pBackGroundVideoWidget->setMediaObject(pBackGroundVideoPlayer);
  11.  
  12.     pBackGroundVideoPlayer->setMedia(QUrl::fromLocalFile("bTest.wmv"));
  13.     pBackGroundVideoPlayer->setVolume(100);
  14.     pBackGroundVideoPlayer->play();
  15.  
  16.     pMainScene->addWidget(pBackGroundVideoWidget);
  17.  
  18.     ui.mainView->setScene(pMainScene);
  19.     ui.mainView->show();
  20. }
