What version of MATLAB are you using? Do you the Video and Image Processing Blockset, or the newer Computer Vision System Toolbox?

If you just want to view the video one frame at a time, then just use the "Next Step" button on the toolbar. Just below the printer icon there is the "Continue" button and next to that is the "Next Step" button. That steps through the video frame by frame.

You should not start a new thread for the identical topic:

http://www.mathworks.com/matlabcentral/answers/48850-how-to-read-frames-of-a-video

The From Multimedia File Block outputs the video one frame at a time so if you connect that block to another block, you will be processing the video one frame at a time.

I started a new thread because I was thinking that may be I have asked the wrong question thats why no one is answering it. Would it be possible to view that single frame at a time in simulink because when I use video viewer it displays the whole video.
