pyqt-graphics-video-item-video-player

Video(mp4 file only) player using QGraphicsVideoItem. Control widget at the bottom is shown/hidden followed by cursor's movement.

Note: You need K-Lite Codec to play the video with this.

Requirements

PyQt5 >= 5.8

Setup

python -m pip install git+https://github.com/yjg30737/pyqt-graphics-video-item-video-player --upgrade

Included Packages

Usage

This video player is mp4 only.

You can set the video file by dropping it to the window. That is the only way.

Example

Code Sample

from PyQt5.QtWidgets import QApplication
from pyqt_graphics_video_item_video_player.videoPlayer import VideoPlayer

if __name__ == "__main__":
    import sys

    app = QApplication(sys.argv)
    videoPlayer = VideoPlayer()
    videoPlayer.show()
    app.exec_()

Result

1. Preview of interaction between cursor movement and control widget visibility

example.mp4

Control widget is going to show when

The cursor enters into the window
The cursor stays on the control widget
The cursor moves again

Control widget is going to hide when

The cursor leaves from the window
The cursor stays outside of the control widget

2. Preview of watching video with the pyqt-graphics-video-item-video-player and using control widget to navigate the video (Example video is result video of pyqt-find-replace-text-widget.) (Note: Style of slider and buttons are set to old version in the example.)

example.mp4

Note

QGraphicsVideoItem's video quality is worse than QVideoWidgets.

You maybe wonder why did i make this in the first place.

Because for some reasons, I can't show the control widget (which has transparent background) over the QVideoWidget.

I'm still trying to figure out the way to solve this problem.

One more thing, There are some flaws in timer feature and button toggling. I will fix it.

How to implement a shape selection panel for rendering in PyQt5?

I'm designing graphic editor. As a scene for drawing, I need to use exactly QGraphicsScene. I implemented adding rectangles and ellipses to the scene with two buttons.

I need to implement dragging the faigures from the panel to the canvas, approximately as in the picture:

What widgets or buttons can I use for this custom panel? Maybe there is an information an example with the implementation of a similar panel?

The program code with the implementation of adding shapes and the interface image:
`from PyQt5.QtWidgets import *
from PyQt5.QtGui import *
from PyQt5.QtCore import *
import sys

window class

class Window(QMainWindow):
def init(self):
super().init()

    wid = QWidget()
    self.setCentralWidget(wid)

    # setting title
    self.setWindowTitle("Paint with PyQt5")

    # setting geometry to main window
    self.setGeometry(100, 100, 800, 600)


    # Defining a scene rect of 400x200, with it's origin at 0,0.
    # If we don't set this on creation, we can set it later with .setSceneRect
    self.scene = QGraphicsScene(0, 0, 400, 200)

    # Set all items as moveable and selectable.
    for item in self.scene.items():
        item.setFlag(QGraphicsItem.ItemIsMovable)
        item.setFlag(QGraphicsItem.ItemIsSelectable)

    # Define our layout.
    vbox = QVBoxLayout()

    up = QPushButton("Rect")
    up.clicked.connect(self.add_rect)
    vbox.addWidget(up)

    down = QPushButton("Elips")
    down.clicked.connect(self.add_elips)
    vbox.addWidget(down)

    view = QGraphicsView(self.scene)
    view.setRenderHint(QPainter.Antialiasing)

    hbox = QHBoxLayout(self)
    hbox.addLayout(vbox)
    hbox.addWidget(view)

    wid.setLayout(hbox)

def add_rect(self):
    rect = QGraphicsRectItem(0, 0, 200, 50)
    rect.setPos(50, 20)
    rect.setFlag(QGraphicsItem.ItemIsMovable)
    rect.setFlag(QGraphicsItem.ItemIsSelectable)
    self.scene.addItem(rect)

def add_elips(self):
    ellipse = QGraphicsEllipseItem(0, 0, 100, 100)
    ellipse.setPos(75, 30)
    ellipse.setFlag(QGraphicsItem.ItemIsMovable)
    ellipse.setFlag(QGraphicsItem.ItemIsSelectable)
    self.scene.addItem(ellipse)

create pyqt5 app

App = QApplication(sys.argv)

create the instance of our Window

window = Window()

showing the window

window.show()

start the app

sys.exit(App.exec())`
