Python OpenCV捕获不工作MFVideoFormat_RGB24（未找到编解码器）遇到此问题，如何解决？

我正在制作python应用程序我需要openCV库这是我的代码：

# importing the required modules
import cv2
import numpy as np

# capturing from the first camera attached
cap = cv2.VideoCapture(0)

# will continue to capture until 'q' key is pressed
while True:
    ret, frame = cap.read()
    cv2.imshow('frame', frame)

    # Program will terminate when 'q' key is pressed
    if cv2.waitKey(1) & 0xFF == ord('q'): 
        break

# Releasing all the resources
cap.release()
cv2.destroyAllWindows()

运行代码时，出现以下错误：

[ WARN:0] global C:\Users\appveyor\AppData\Local\Temp\1\pip-req-build-wwma2wne\opencv\modules\videoio\src\cap_msmf.cpp (677) CvCapture_MSMF::initStream Failed to set mediaType (stream 0, (640x480 @ 30) MFVideoFormat_RGB24(codec not found)

我想它可能需要一个编解码器驱动程序，但我不知道如何修复错误 请帮助我的朋友们

试试看

cap=cv2.VideoCapture0，cv2.cap_DSHOW以下代码为我解决了这个问题：cap=cv2.VideoCapture0，cv2.cap_DSHOW
