cv2.error: OpenCV(3.4.3)

[yasersakkaf]

I am getting this error when I try to run this code. I know the error is related to Open CV but can't understand what the error actually is:

Here the code and the error:

import cv2
video = cv2.VideoCapture('video.mp4')
success, image = video.read()
ret, jpeg = cv2.imencode('.jpg', image)
Traceback (most recent call last):
File "", line 1, in

The same here. Did you solved?

I used OpenCV version '4.1.0' and it works for me.
What version of OpenCV are you using?

[rjunior8]

opencv-python==4.1.0.25

I solved. I executed it in debian and it worked. But it's playing slow. And when I make two connections (2 browsers), I got this:

error while decoding MB 73 15, bytestream 5111
left block unavailable for requested intra mode
error while decoding MB 0 16, bytestream 5097

and then the app stops.
