QGraphicsVideoItem ¶

概要 ¶

详细描述 ¶

Attaching a QGraphicsVideoItem 到 QMediaObject allows it to display the video or image output of that media object. A QGraphicsVideoItem is attached to a media object by passing a pointer to the QMediaObject 到 setMediaObject() 函数。

player = new QMediaPlayer(this);
QGraphicsVideoItem *item = new QGraphicsVideoItem;
player->setVideoOutput(item);
graphicsView->scene()->addItem(item);
graphicsView->show();
player->setMedia(QUrl("http://example.com/myclip4.ogv"));
player->play();
											

注意 ：每次只可以把单个显示输出附加到媒体对象。
