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")))

        controlLayout = QHBoxLayout()
        controlLayout.setContentsMargins(0, 0, 0, 0)
        controlLayout.addWidget(openButton)
        controlLayout.addWidget(self.playButton)

    def positionChanged(self, position):

    def setPosition(self, position):
        self.mediaPlayer.setPosition(position)

    def handleError(self):

    player = VideoPlayer()
    player.setWindowTitle("Player")
    player.resize(600, 400)
    player.show()
    sys.exit(app.exec_())

Thank you, Can you explain me why is fileName, _ = QFileDialog.getOpenFileName(self, "Selecciona los mediose", ".", "Video Files (*.mp4 *.flv *.ts *.mts *.avi)") and not just fileName= — AnimeZero, Sep 08 '19 at 13:32
@AnimeZero in `PyQt5` static `QtWidgets.QFileDialog.getOpenFileName(...)` Return type: `(fileName, selectedFilter)` — S. Nick, Sep 08 '19 at 14:02

I simply convert the @S.Nick answer to PyQt6
