可以使用PyQt6中的QMovie类来加载mp4文件,并将其转换为QPixmap进行显示。同时,可以使用线程来实现实时显示。具体实现可以参考以下代码:
```python
from PyQt6.QtCore import Qt, QThread, pyqtSignal
from PyQt6.QtGui import QPixmap, QMovie
from PyQt6.QtWidgets import QApplication, QMainWindow, QLabel, QVBoxLayout, QWidget
class VideoThread(QThread):
change_pixmap_signal = pyqtSignal(QPixmap)
def __init__(self, video_path):
super().__init__()
self.video_path = video_path
def run(self):
movie = QMovie(self.video_path, parent=None, autoDelete=True)
movie.start()
while True:
pixmap = movie.currentPixmap()
self.change_pixmap_signal.emit(pixmap)
class MainWindow(QMainWindow):
def __init__(self):
super().__init__()
self.label = QLabel(self)
self.setCentralWidget(QWidget(self))
self.centralWidget().setLayout(QVBoxLayout())
self.centralWidget().layout().addWidget(self.label)
self.thread = VideoThread('video.mp4')
self.thread.change_pixmap_signal.connect(self.set_image)
self.thread.start()
def set_image(self, image):
self.label.setPixmap(image)
if __name__ == '__main__':
app = QApplication([])
window = MainWindow()
window.show()
app.exec()
```
当然,这个代码只是一个简单的示例,你可以根据具体需求进行修改和完善。
