【问题描述】:
这是我的代码,我遇到了问题。请问有什么办法解决? 我做了一个屏幕录像机:
import numpy as np
import cv2
import pyautogui
codec = cv2.VideoWriter_fourcc(*"XVID")
out = cv2.VideoWriter("Recorded.avi", codec, 60, (1366,768))
cv2.namedWindow("Recording", cv2.WINDOW_NORMAL)
cv2.resizeWindow("Recording", 480, 270)
while True:
img = pyautogui.screenshot #capturing screenshot
frame = np.array(img) # converting the image into numpy array representation
frame = cv2.cvtColor(frame, cv2.COLOR_BGR2RGB) # converting the BGR image into RGB image
out.write(frame) # writing the RBG image to file
cv2.imshow('Recording', frame) # display screen/frame being recorded
if cv2.waitKey(1) == ord('q'): # Wait for the user to press 'q' key to stop the recording
break
out.release() # closing the video file
cv2.destroyAllWindows() # destroying the recording window
这里的问题:
Traceback(最近一次调用最后一次): 文件“C:\Users\mhmdj\PycharmProjects\learn\main.py”,第 13 行,在 frame = cv2.cvtColor(frame, cv2.COLOR_BGR2RGB) # 将BGR图像转换为RGB图像 cv2.error: OpenCV(4.5.2) ????错误:(-5:Bad argument) in function 'cvtColor'
重载解析失败:
不支持 src 数据类型 = 17 参数“src”的预期 Ptrcv::UMat
【问题讨论】:
-
你可以试试
frame = np.array(img, dtype="uint8")吗? -
数据类型 17 可能是 CV_8SC3,这是一个奇怪的类型
-
您确定不必在此处拨打电话吗?:
img = pyautogui.screenshot
