• python 实现屏幕录制


    用python实现屏幕录制

    PIL 即pollow 的安装命令如下:
    pip install pillow
    其中cv2的安装是下面这条命令
    pip install opencv-python

    代码实现:

    # coding: utf-8
    from PIL import ImageGrab
    import  numpy as np
    import  cv2
     
    fps = 20
    start = 3  # 延时录制
    end = 15  # 自动结束时间
     
    curScreen = ImageGrab.grab()  # 获取屏幕对象
    height, width = curScreen.size
     
    video = cv2.VideoWriter('video02.avi', cv2.VideoWriter_fourcc(*'XVID'), fps, (height, width))
     
    imageNum = 0
    while True:
        imageNum += 1
        captureImage = ImageGrab.grab()  # 抓取屏幕
        frame = cv2.cvtColor(np.array(captureImage), cv2.COLOR_RGB2BGR)
     
        # 显示无图像的窗口
        cv2.imshow('capturing', np.zeros((1, 255), np.uint8))
       
        # 控制窗口显示位置,方便通过按键方式退出
        cv2.moveWindow('capturing', height - 100, width - 100)  
        if imageNum > fps * start:
            video.write(frame)
        # 退出条件    
        if cv2.waitKey(50) == ord('q') or imageNum > fps * end:
            break
    video.release()
    cv2.destroyAllWindows()
