I have a .tar file containing a .mp4 video. I need to open them via OpenCV (v2.4.8) in PyQt4 without extracting the archive to the file system.

Here there solution for reading images from tar

Instance:

import cv2
import numpy as np
import tarfile

tar0 = tarfile.open('files.tar')
fileg = tar0.extractfile('1.mp4')#  (may be convert fileg to VideoCapture?)

What is the wrong with the solution in that link? – Pedro Jul 29 '16 at 12:58
[answer](http://stackoverflow.com/a/25198846/5781248) seems applicable. – J.J. Hakala Jul 30 '16 at 11:40
The solution in the link is correct, but cv2.imdecode method is not usable for a video file. – Даниил Ярушин Aug 01 '16 at 03:36
