from PyQt5 import QtCore, QtGui, QtWidgets

class Ui_MainWindow(object):
    def setupUi(self, MainWindow):
        MainWindow.setObjectName("MainWindow")
        MainWindow.resize(800, 600)
        self.centralwidget = QtWidgets.QWidget(MainWindow)
        self.centralwidget.setObjectName("centralwidget")
        self.widget_video = QtWidgets.QWidget(self.centralwidget)
        self.widget_video.setGeometry(QtCore.QRect(140, 100, 511, 311))
        self.widget_video.setObjectName("widget_video")
        MainWindow.setCentralWidget(self.centralwidget)
        self.menubar = QtWidgets.QMenuBar(MainWindow)
        self.menubar.setGeometry(QtCore.QRect(0, 0, 800, 26))
        self.menubar.setObjectName("menubar")
        MainWindow.setMenuBar(self.menubar)
        self.statusbar = QtWidgets.QStatusBar(MainWindow)
        self.statusbar.setObjectName("statusbar")
        MainWindow.setStatusBar(self.statusbar)

        self.retranslateUi(MainWindow)
        QtCore.QMetaObject.connectSlotsByName(MainWindow)

    def retranslateUi(self, MainWindow):
        _translate = QtCore.QCoreApplication.translate
        MainWindow.setWindowTitle(_translate("MainWindow", "MainWindow"))

以上是Ui界面

from PyQt5.QtWidgets import *
from PyQt5.QtMultimedia import *
from PyQt5.QtMultimediaWidgets import QVideoWidget
from PyQt5.QtCore import QUrl
from tt import Ui_MainWindow
import sys

class myMainWindow(Ui_MainWindow,QMainWindow):
    def __init__(self):
        super(Ui_MainWindow, self).__init__()
        self.setupUi(self)
        self.player = QMediaPlayer(self)
        self.widget_video = QVideoWidget(self)
        self.player.setVideoOutput(self.widget_video)
        self.player.setMedia(QMediaContent(QUrl.fromLocalFile("cat.avi")))  # local source
        self.player.play()  # 播放视频


if __name__ == '__main__':
    app = QApplication(sys.argv)
    video_gui = myMainWindow()
    video_gui.show()
    sys.exit(app.exec_())

以上是主程序界面
