文章介绍了如何使用PySide6库在GUI应用中创建一个视频播放器，包括控件如QTableWidget、QSlider和QPushButton的集成，以及播放、暂停、切换视频的功能实现。

一、界面如下

包含控件 qcombox、qtablewidget、qpushbotton、qverticalslider

二、运行代码

media_player.py

import sys
 
from PySide6 import QtWidgets
from PySide6.QtWidgets import *
from PySide6.QtMultimedia import *
from PySide6.QtMultimediaWidgets import QVideoWidget
from PySide6.QtCore import QTimer
#from PySide6.QtMultimedia import QMediaContent
from test_ui import Ui_MainWindow
import cv2 

class MainWindow(QMainWindow):
    def __init__(self, parent = None) :
        super().__init__(parent)
        self.ui = Ui_MainWindow()
        
        #self.ui.tableWidget = QTableWidget()
        
        self.ui.setupUi(self)
        
        self.ui.tableWidget.setRowCount(6)
        self.ui.tableWidget.setColumnCount(1)
        
        self.i = 0
        self.list_i = 0
        self.maxValue = 1000
        self.timer = QTimer()
        
        self.video_name_t = []
        
        # 播放器
        self.player = QMediaPlayer()
        self.player.setVideoOutput(self.ui.wdt_camera)
        
        #self.ui.tableWidget = QTableWidget(1,6)
        # 按钮打开文件
        self.ui.btn_open.clicked.connect(self.openVideoFile)
        # 播放
        self.ui.btn_play.clicked.connect(self.playVideo)  # play
        # 暂停

        self.player.setSource(video_name)
        self.media_duration = get_duration_from_cv2(video_name)
        print(self.media_duration)

            self.video_name_t.append(video_name)
            item = QTableWidgetItem(video_name)
            item.setText(video_name)
            self.ui.tableWidget.setItem(0,self.i, item)
            self.i += 1
        self.ui.bar_slider.setMaximum(round(self.media_duration*10))
        self.time_count = 0
        self.player.play()
        self.timer.setInterval(100)
        self.timer.start()

        #print(self.player.availableMetaData())
 
    def playVideo(self):
        self.player.play()
        self.ui.bar_slider.setMaximum(round(self.media_duration*10))
        #self.time_count = 0
        self.timer.setInterval(100)
        self.timer.start()
        self.timer.timeout.connect(self.onTimerOut)
