how to acquire each frame from video

Hi I am trying to acquire one frame at a time from a video. So I tried this

obj = imaq.VideoDevice('winvideo',1);
load train_data
i = 1;
while i == 1                       
    I = step(obj);

However I don't have the image acquistion toolbox and hence this wont work Is there a way I could rewrite this ?

Use the built-in webcam support: http://www.mathworks.com/support/2014a/matlab/8.3/demos/webcam-support.html. I have not tried it since I have the Image Acquisition Toolbox.

Is it possible for me to rewrite the code so that i can acquire frame by frame from a video. (Not a live one but one saved in the path)
