How to read video file from sftp location using opencv in python [closed]

edit

I am facing issue in reading file from sftp location using opencv lib. Can you tell me how to read file from sftp location or sftp file object. If can you tell me read large file directly to opencv lib then it's good things.

import paramiko
import cv2
import numpy as np

client = paramiko.SSHClient()
client.set_missing_host_key_policy(paramiko.AutoAddPolicy())
client.connect("IPADDRESS", port=22, username='USERNAME', password='PASSWORD')
t = client.get_transport()
sftp = paramiko.SFTPClient.from_transport(t)
sftp.chdir("/home/bizviz/devanshu_copy")

obj = sftp.open("SampleVideo_1280x720_1mb.mp4")

cap = cv2.VideoCapture.open(obj)

while True:
    _,frame = cap.read()
    print(frame)
    cv2.imshow('res', frame)
    key = cv2.waitKey(1)
    if key == 27:
        break

cap.release()
cv2.destroyAllWindows()
