python调用DXGI实时快速截屏，是python截屏的最快版了

import os import time os.getcwd() os.add_dll_directory('H:\pythonDXGI截屏\DXGI.pyd') from ctypes import windll import cv2 import numpy as np windll.winmm.timeBeginPeriod(1) stop = windll.kernel32.Sleep import cv2 # 把DXGI.pyd 复制到当前路径 import DXGI import torch g = DXGI.capture(0, 0, 320, 320) # 屏幕左上角 到 右下角 （x1, y1 ,x2 ,y2) while True: current_time = time.time() img = g.cap() img = np.array(img) # # 将图片转 BGR img = cv2.cvtColor(img, cv2.COLOR_BGRA2BGR) last_time=time.time() time_used = last_time - current_time print(time_used) current_time, last_time=0, 0 cv2.imshow('c',img) cv2.waitKey(1)
