我想在我的 Ubuntu 系统中阅读 HTTPS URL 视频而不下载它们。我可以在 Windows 操作系统中执行此操作，但是当我尝试使用相同的 opencv VideoCapture 方法在 Ubuntu 中运行相同的代码时，它无法获取任何帧。
为什么会这样？
我在 Ubuntu 和 Windows 中都使用了相同的 opencv 版本，任何人都可以指导我找到一个解决方法，一个教程，我可以使用它来编译 opencv 和流 url 视频或任何其他在 Ubuntu 中支持此功能的库？
我几乎尝试了所有方法，但没有取得任何成果，这导致我最终提出这个问题。

最佳答案
我的代码正在运行
import cv2
cap = cv2.VideoCapture('https://192.168.00.00:8080/video')
cv2.namedWindow('live cam', cv2.WINDOW_NORMAL)
while(True):
ret, frame = cap.read()
img_resize = cv2.resize(frame, (960, 540))
cv2.imshow('live cam', img_resize)
if cv2.waitKey(1) & 0xFF == ord('q'):
break
cap.release()
cv2.destroyAllWindows()
