from PyQt5.QtWidgets import QApplication, QMainWindow, QVBoxLayout, QWidget, QVideoWidget
from PyQt5.QtMultimedia import QMediaPlayer, QMediaContent
from PyQt5.QtMultimediaWidgets import QVideoWidget
import sys

app = QApplication(sys.argv)

# 创建视频播放器
player = QMediaPlayer()

# 设置视频源
video_path = "本地视频文件路径"
media = QMediaContent(QUrl.fromLocalFile(video_path))
player.setMedia(media)

# 创建视频显示窗口
video_widget = QVideoWidget()

# 设置视频输出
player.setVideoOutput(video_widget)

# 创建主窗口
main_window = QMainWindow()

# 设置主窗口布局
layout = QVBoxLayout()
layout.addWidget(video_widget)

# 设置主窗口属性
main_window.setWindowTitle("闪亮app")
main_window.setGeometry(100, 100, 800, 600)

# 将布局应用到主窗口
central_widget = QWidget(main_window)
central_widget.setLayout(layout)
main_window.setCentralWidget(central_widget)

# 显示主窗口
main_window.show()

# 播放视频
player.play()

sys.exit(app.exec_())
