pyqt5看视频软件源码
您可以使用QtMultimedia模块中的QMediaPlayer类来设置视频。以下是一个基本的示例代码:
```python
from PyQt5.QtCore import QUrl
from PyQt5.QtMultimedia import QMediaPlayer, QMediaContent
from PyQt5.QtWidgets import QApplication, QMainWindow, QWidget, QVBoxLayout, QPushButton, QFileDialog
class VideoPlayer(QMainWindow):
def __init__(self):
super().__init__()
self.setWindowTitle("Video Player")
self.setGeometry(100, 100, 640, 480)
# Create media player object
self.mediaPlayer = QMediaPlayer(None, QMediaPlayer.VideoSurface)
# Create a widget for video output
videoWidget = QWidget(self)
self.setCentralWidget(videoWidget)
layout = QVBoxLayout()
videoWidget.setLayout(layout)
# Create open button
openButton = QPushButton('Open Video')
openButton.clicked.connect(self.openFile)
layout.addWidget(openButton)
# Set media player to the output widget
self.mediaPlayer.setVideoOutput(videoWidget)
def openFile(self):
filename, _ = QFileDialog.getOpenFileName(self, "Open Video")
if filename:
self.mediaPlayer.setMedia(QMediaContent(QUrl.fromLocalFile(filename)))
self.mediaPlayer.play()
if __name__ == '__main__':
app = QApplication([])
player = VideoPlayer()
player.show()
app.exec_()
```
在这个示例中,我们创建了一个`VideoPlayer`类,它继承自`QMainWindow`,并具有一个基本的用户界面。我们使用`QMediaPlayer`类和`QWidget`类来设置视频输出。`openFile`函数用于打开视频文件并将其设置为媒体播放器的媒体内容,然后播放视频。
您可以根据需要修改此基本示例以满足您的需求。
