I am trying to put two videos in a single frame. But I am getting Type Error. Please check below code.

import cv2 import numpy as np cap1=cv2.VideoCapture('first.avi') cap2=cv2.VideoCapture('fourth.avi') fps = cap1.get(cv2.CAP_PROP_FPS) global Video_h global Video_w Video_h = cap1.get(cv2.CAP_PROP_FRAME_HEIGHT) Video_w = cap1.get(cv2.CAP_PROP_FRAME_WIDTH) while (True): frame=np.zeros([int(2Video_h),int(3Video_w),3], dtype=np.uint8) ret,frame1=cap1.read() ret,frame2=cap2.read() frame[0:int(Video_h),0:int(Video_w)] = frame1 frame[0:int(Video_h),int(Video_w)-200:int(Video_w*2)-200] = frame2 cv2.namedWindow("window", cv2.WND_PROP_FULLSCREEN) #cv2.setWindowProperty("window",cv2.WND_PROP_FULLSCREEN,cv2.WINDOW_FULLSCREEN) cv2.imshow("window", frame) if cv2.waitKey(1) & 0xff == ord('q'): break

below error is coming: Traceback (most recent call last): File "c:/Users/shiva/Documents/Python/test.py", line 15, in frame[0:int(Video_h),int(Video_w)-200:int(Video_w*2)-200] = frame2 TypeError: int() argument must be a string, a bytes-like object or a number, not 'NoneType'
