    Try it:

    from PyQt5.QtGui import QIcon, QFont
    from PyQt5.QtCore import QDir, Qt, QUrl, QSize
    from PyQt5.QtMultimedia import QMediaContent, QMediaPlayer
    from PyQt5.QtMultimediaWidgets import QVideoWidget
    from PyQt5.QtWidgets import (QApplication, QFileDialog, QHBoxLayout, QLabel, 
            QPushButton, QSizePolicy, QSlider, QStyle, QVBoxLayout, QWidget, QStatusBar)
    
    class VideoPlayer(QWidget):
    
        def __init__(self, parent=None):
            super(VideoPlayer, self).__init__(parent)
    
            self.mediaPlayer = QMediaPlayer(None, QMediaPlayer.VideoSurface)
    
            btnSize = QSize(16, 16)
            videoWidget = QVideoWidget()
    
            openButton = QPushButton("Open Video")   
            openButton.setToolTip("Open Video File")
            openButton.setStatusTip("Open Video File")
            openButton.setFixedHeight(24)
            openButton.setIconSize(btnSize)
            openButton.setFont(QFont("Noto Sans", 8))
            openButton.setIcon(QIcon.fromTheme("document-open", QIcon("D:/_Qt/img/open.png")))
            openButton.clicked.connect(self.abrir)
    
            self.playButton = QPushButton()
            self.playButton.setEnabled(False)
            self.playButton.setFixedHeight(24)
            self.playButton.setIconSize(btnSize)
