unable to read .mp4 from opencv

The following is the code used to read the .mp4 video from python. The code cap.isOpened() is returning false.

FYI: I installed the relavant codes and copied opencv_ffmpeg_64.dll into python folder (/usr/local/lib/python2.7)

-Opencv version: 3.0

-Python:2.7 

import numpy as np
import cv2
import gtk
import pygtk
import gobject

count=0
loop=0
cascPath = 'haarcascade_frontalface_default.xml'
faceCascade = cv2.CascadeClassifier(cascPath)
cap = cv2.VideoCapture('sample.mp4')

print (cap.isOpened())

Please suggest what best can be done?

You're probably missing FFMPEG. OpenCV needs the codec information to decode the videos, which ffmpeg provides.

Download FFMPEG from http://ffmpeg.zeranoe.com/builds/ by hitting the 'Download FFmpeg' button. Ensure you have selected the correct version, architecture and 'Statis' build. Unzip the downloaded file, rename it as 'ffmpeg' and move to C:\ (for eg). Now add the path C:\ffmpeg\bin to your PATH system variable.

The steps are detailed here with pictures: http://www.wikihow.com/Install-FFmpeg-on-Windows
