How to overlay an editable rectangle box when playing a video, similar to the entity QGraphicItem

Sorry for the belated reply.

I made a branch for this, you can clone this with

git clone https://github.com/yjg30737/pyqt-graphics-video-item-video-player --branch feature/boundingbox

Plus, you have to install the pyqt-bounding-box since this uses it as a bounding box over the screen.

After did that you can just run it.

This is the result. You can move and resize it while playing the video.

So how to overlay and editable rectangle box? Read below.

self.__item = QGraphicsVideoItem()
self.__item.setAcceptDrops(True)

self.__box = BoundingBox()
self.__box.setColor(QColor(255, 255, 255))

# add both QGraphicsVideoItem and BoundingBox to scene
scene.addItem(self.__item)
scene.addItem(self.__box)

w_f = float(self.contentsRect().size().width())
h_f = float(self.contentsRect().size().height())
self.__item.setSize(QSizeF(w_f, h_f))
self.__box.setSize(w_f, h_f)

# item should be stacked before the box, so you should use "stackBefore"
# this makes you can move and resize the box
self.__item.stackBefore(self.__box)
self.setScene(scene)

This is the part of the source of videoGraphicsView.py

Hope this help 🙂
