QtMediaplayer wont work on frameless and translucent background PyQt5

Question

I am making a videoplayer with QMediaplayer but it wont work on frameless and translucent background window.I want to make a round corner windows so i need frameless and translucent window. Here is my code:

from PyQt5.QtCore import Qt, QUrl
from PyQt5.QtMultimedia import QMediaContent, QMediaPlayer
from PyQt5.QtMultimediaWidgets import QVideoWidget
from PyQt5.QtWidgets import QApplication,QMainWindow,QFrame
import sys     
class Player(QMainWindow):
    def __init__(self, parent=None):
        super().__init__(parent)
        self.setWindowTitle("PyQt Video Player Widget Example") 
        self.resize(600,400)
        self.frame=QFrame(self)
        self.frame.setStyleSheet('background:grey;border-radius:20px;')
        self.setCentralWidget(self.frame)
        #self.setWindowFlag(Qt.FramelessWindowHint)
        #self.setAttribute(Qt.WA_TranslucentBackground)
        self.mediaPlayer = QMediaPlayer(None, QMediaPlayer.VideoSurface)
        videoWidget = QVideoWidget(self.frame)
        videoWidget.setGeometry(10,10,580,380)
        self.resize(600,400)
        self.mediaPlayer.error.connect(self.handleError)
        self.mediaPlayer.setVideoOutput(videoWidget)
        self.mediaPlayer.setMedia(
                         QMediaContent(QUrl.fromLocalFile("C:/Users/mishra/Desktop/HiddenfilesWindow/10000000_1874628825927192_6229658593205944320_n(1).mp4")))
        self.mediaPlayer.play()
    def handleError(self):
        print("Error: " + self.mediaPlayer.errorString())
          
if __name__ == "__main__":
    import sys
    app = QApplication(sys.argv)
    window = Player()
    
    window.show()
    sys.exit(app.exec_())

After setting translucent background it only plays audio not video.Anybody knows how to fix it?

Try it:

import sys
from PyQt5.QtCore import Qt, QUrl, QRectF
from PyQt5.QtGui import QPainterPath, QRegion
from PyQt5.QtMultimedia import QMediaContent, QMediaPlayer
from PyQt5.QtMultimediaWidgets import QVideoWidget
from PyQt5.QtWidgets import QApplication, QMainWindow, QFrame, QWidget, QHBoxLayout
     

class Player(QMainWindow):
    def __init__(self, parent=None):
        super().__init__(parent)
        self.setWindowTitle("PyQt Video Player Widget Example") 
        self.resize(600,400)
        self.frame= QFrame(self)  
        
#        self.frame.setStyleSheet('background:grey; border-radius: 20px;')
        self.setStyleSheet("Player {background: #000;}")                   # +++
        
        self.setCentralWidget(self.frame)
#        self.setWindowFlag(Qt.FramelessWindowHint)
#        self.setAttribute(Qt.WA_TranslucentBackground)

        layout = QHBoxLayout(self.frame)                                   # +++
        videoWidget = QVideoWidget()                                       # +++
        layout.addWidget(videoWidget)                                      # +++

        
        self.mediaPlayer = QMediaPlayer(None, QMediaPlayer.VideoSurface)
#        videoWidget = QVideoWidget(self.frame)             
#        videoWidget.setGeometry(10,10,580,380)
#        self.resize(600,400)
        self.mediaPlayer.error.connect(self.handleError)
        self.mediaPlayer.setVideoOutput(videoWidget)
        self.mediaPlayer.setMedia(
            QMediaContent(QUrl.fromLocalFile("Samonastrojka.avi")))
        self.mediaPlayer.play()

# +++ vvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvv        
    def resizeEvent(self, event):
        path = QPainterPath()
        path.addRoundedRect(QRectF(self.rect()), 20, 20)
        reg = QRegion(path.toFillPolygon().toPolygon())
        self.setMask(reg)
# +++ ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
        
    def handleError(self):
        print("Error: " + self.mediaPlayer.errorString())
   
   
if __name__ == "__main__":
    app = QApplication(sys.argv)
    window = Player()
    window.show()
    sys.exit(app.exec_())
