QGpahicsVideoItem plays video not QVideoWidget

Hi,

I've tested the two ways to play a video with qtmultimedia : the first with QGraphicsVideoItem and the second with QVideoWidget. As said in the summary, QGraphicsVideoItem plays my video (audio and video) but i can't play the same video in the same environment with QVideoWidget. Instead, i got the "internal data flow error" message (for QVideoWidget).

I've installed all the Gstreamer plugins (yum install gstreamer*, to be sure that i'm not missing anything). But i'm not suspecting to be a plugin or codec cause because QGraphicsVideoItem plays fine unless QVideoWidget needs more plugins than QGraphicsVideoItem.

Here are the 2 examples :

QGraphicsVideoItem example : (works)

QGraphicsView * graphicsView = new QGraphicsView;
QMediaPlayer * player = new QMediaPlayer;

QGraphicsScene * scene = new QGraphicsScene;
graphicsView->setScene(scene);

QGraphicsVideoItem *item = new QGraphicsVideoItem;
player->setVideoOutput(item);
graphicsView->scene()->addItem(item);
graphicsView->show();

player->setMedia(QUrl::fromLocalFile("/home/user/video.mpg"));
player->play();

QVideoWidget example : (doesn’t work, got “Internal data stream error”)

QMediaPlayer * player = new QMediaPlayer;
player->setMedia(QUrl::fromLocalFile("/home/user/video.mpg"));

QVideoWidget * videoWidget = new QVideoWidget;
videoWidget->show();
player->setVideoOutput(videoWidget);

player->play();

Regards.
