pycharm录制视频代码

这里提供一段使用pyqt5和opencv库实现录制屏幕的代码，可以在pycharm中运行。具体实现过程可以参考引用、、中提到的相关知识点。

import sys
import cv2
from PyQt5.QtWidgets import QApplication, QWidget, QPushButton, QLabel, QVBoxLayout
from PyQt5.QtGui import QIcon, QPixmap, QImage
from PyQt5.QtCore import Qt, QThread, pyqtSignal, pyqtSlot


class ScreenRecorder(QThread):
    change_pixmap_signal = pyqtSignal(QImage)

    def __init__(self):
        super().__init__()
        self._run_flag = True

    def run(self):
        screen = QApplication.primaryScreen()
        while self._run_flag:
            if screen is not None:
                screenshot = screen.grabWindow(0)
                img = screenshot.toImage()
                self
