帮我生成一个显示两个网络摄像头视频的wxpython代码

好的，以下是一个显示两个网络摄像头视频的wxpython代码：

import wx
import cv2

class CameraPanel(wx.Panel):
    def __init__(self, parent, cap):
        wx.Panel.__init__(self, parent)
        self.cap = cap
        self.SetSize((640, 480))
        self.Bind(wx.EVT_PAINT, self.OnPaint)

    def OnPaint(self, evt):
        ret, frame = self.cap.read()
        if ret:
            frame = cv2.cvtColor(frame, cv2.COLOR_BGR2RGB)
            h, w = frame.shape[:2]
            bmp = wx.Bitmap.FromBuffer(w, h, frame)
            dc = wx.BufferedPaintDC(self)
            dc.DrawBitmap(bmp, , )

class MainFrame(wx.Frame):
    def __init__(self):
        wx.Frame.__init__(self, None, title='双摄像头', size=(128, 480))
        self.cap1 = cv2.VideoCapture()
        self.cap2 = cv2.VideoCapture(1)
        self.panel1 = CameraPanel(self, self.cap1)
        self.panel2 = CameraPanel(self, self.cap2)
        hbox = wx.BoxSizer(wx.HORIZONTAL)
        hbox.Add(self.panel1, 1, wx.EXPAND)
        hbox.Add(self.panel2, 1, wx.EXPAND)
        self.SetSizer(hbox)
        self.Centre()
        self.Show()

if __name__ == '__main__':
    app = wx.App()
    frame = MainFrame()
    app.MainLoop()

希望能对您有所帮助！
