Description

Platform: Windows Vista 32-bit, Python 2.7.5, OpenCV 2.4.7.2

Here is a code snippet that illustrates the bug:

import cv2
path = 'D:/Videos/'             # path to the following *.avi file
video = 'toy_plane_liftoff.avi' # http://cinelerra.org/footage/
vid = cv2.VideoCapture(path+video)
result = vid.isOpened()
print result

[result returns False for this avi]

No errors are generated but this avi does not open. However, it does open and display in Windows media player, VLC, mplayer, etc. Note, this is a short, test avi that can be downloaded from the link given in the comment.
