Detailed Description▲
Attaching a QGraphicsVideoItem to a QMediaPlayer or QCamera allows it to display the video or image output of that media object.
player = new QMediaPlayer(this);
QGraphicsVideoItem *item = new QGraphicsVideoItem;
player->setVideoOutput(item);
graphicsView->scene()->addItem(item);
graphicsView->show();
player->setSource(QUrl("http://example.com/myclip4.ogv"));
player->play();Note: Only a single display output can be attached to a media object at one time.

offset() const
-
void setOffset(const &offset)
size : QSizeF▲
This property holds the video item's size.
QGraphicsVideoItem will draw video scaled to fit size according to its fillMode.
Access functions:

size() const
-
void setSize(const &size)
[read-only] videoSink : QVideoSink* const▲
Returns the underlying video sink that can render video frames to the current item. This property is never nullptr. Example of how to render video frames to QGraphicsVideoItem:
QGraphicsVideoItem *item = new QGraphicsVideoItem;
graphicsView->scene()->addItem(item);
graphicsView->show();
QImage img = QImage("images/qt-logo.png").convertToFormat(QImage::Format_ARGB32);
item->videoSink()->setVideoFrame(QVideoFrame(img));Access functions:
