I'm guessing you're familiar with callbacks in app designer? If not, here's the tutorial.
>> appdesigner.internal.application.openTutorial('BasicCoding')
In the callback function for the button that will read the video image, do something like this:
filename = 'myvideo.mp4';
v = VideoReader(filename);
while hasFrame(v)
imshow(getFrame(v), 'Parent', app.UIAxes);
end

You might need to add a drawnow or pause(0.01) after the imshow to be able to see the video. Not sure how to set the frame rate, as that requires a different function called implay, which doesn't seem to be able to control a UIAxes.
