Qpixmap resize pyqt5

Below is the full implementation of a proper Video Player in PyQt5. There is only really one big change, which is the addition of a slider bar. Changing the position of this Slider will change the current scene playing on the Screen, just like a regular video player. Another change is the addition of an error handling system.Since the Pixmap will be used in an off-screen buffering operation and the aspect ratio will most likely be changed by the parent window being resized, the Pixmap should be redrawn, so scaling the old contents is inefficient. It look like pixmap = QPixmap ( this ->rect ()); is my best bet.The basic idea of doing this is first of all loading the image using QPixmap and adding the loaded image to the Label then resizing the label according to the dimensions of the image, although the resizing part is optional. In order to use Qpixmap and other stuff we have to import following libraries:Below is the full implementation of a proper Video Player in PyQt5.
