How to connect live video camera with gui?

I have built a code which opens a folder for searching an existing video, separating frames of that video and then operating the code. How can I connect real-time camera with the code so that it makes it work on live video?

Here is part of my code:

vidFrames = read(readerobj);
% Get the number of frames.
numFrames = get(readerobj, 'NumberOfFrames');
%Create a MATLAB movie struct from the video frames

I would like to make the program universal, for any mobile device camera not just mine. Does anyone know how to make this possible? :)

Run imaqtool and see what code it makes when you operate the camera. Copy and paste that code into your own program.

It helped but still when i run the program the camera turns on but does not emmit the video.
