在python-Tkin中嵌入网络视频流

Question

我有一个用Tkinter制作的GUI，我正在尝试将http://192.168.0.4:8081/（流在任何浏览器上都能完美工作）的网络流包含到我的python GUI中

camera = cv2.VideoCapture(0)
cameraLabel = tk.Label(root)
cameraLabel.place(x=640,y=380)
videoLoop()

如果我使用上面的代码，我会从我的笔记本电脑摄像头中获取视频

camera = cv2.VideoCapture("http://192.168.0.6:8081/")
cameraLabel = tk.Label(root)
cameraLabel.place(x=640,y=380)
videoLoop()

如果我使用上面的代码，它就不会运行，并给出一个错误，即cv2.VideoCapture attribute error

videoLoop功能如下：

def videoLoop():
    ret, frame = camera.read()
    if ret:
        scale_percent = 70 # percent of original size
        width = int(frame.shape[1] * scale_percent / 100)
        height = int(frame.shape[0] * scale_percent / 100)
        dim = (width, height)
        resized = cv2.resize(frame, dim, interpolation = cv2.INTER_AREA)
        cv2image = cv2.cvtColor(resized, cv2.COLOR_BGR2RGBA)
        img = Image.fromarray(cv2image)
        imgtk = ImageTk.PhotoImage(image=img)
        cameraLabel.imgtk = imgtk
        cameraLabel.configure(image=imgtk)
        cameraLabel.after(1, videoLoop)
