Pyqt5+QMediaPlayer实现简易播放器

最近做导师安排项目使用Pyqt5做了一个界面，分享给大家。具体的实现步骤后续会详细和大家交代，目前先提交一下

一个三个文件,直接复制到自己工程文件中就可以使用了，界面实现如图。目前只实现了视频文件选择，开始暂停停止以及双击放大后续补充会再更新。

1.自定义的widget。myvideowidget.py

from PyQt5.QtMultimediaWidgets import QVideoWidget
from PyQt5.QtCore import *
class myVideoWidget(QVideoWidget):doubleClickedItem = pyqtSignal(str)  # 创建双击信号def __init__(self,parent=None):super(QVideoWidget,self).__init__(parent)def mouseDoubleClickEvent(self,QMouseEvent):     #双击事件self.doubleClickedItem.emit("double clicked")

2.界面文件。single_car_system.py

# -*- coding: utf-8 -*-# Form implementation generated from reading ui file 'single_car_system.ui'
