我正在使用 QMediaplayer 制作视频播放器，但它无法在无框和半透明背景窗口上工作。我想制作圆角窗口，所以我需要无框和半透明窗口。这是我的代码：

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_())

设置半透明背景后，它只播放音频而不播放视频。有人知道如何修复它吗？
