Hellow everyone,
I want to ask about control button's question.
This is my code
clear all;
obj = mmreader('watch.avi');
obj1 = mmreader('can.avi');
obj2 = mmreader('phone.avi');
obj3 = mmreader('book.avi');
vid = read(obj);
vid1 = read(obj1);
vid2 = read(obj2);
vid3 = read(obj3);
%for frame = 1 : size(vid,4)
% bw = im2bw(vid(:,:,:,frame));
frame = 1;
frame1 = 50;
frame2 = 30;
frame3 = 1;
f4 = 1;
while (1)
subplot(2,2,2); imshow(vid(:,:,1,frame));
if frame < size(vid,4)
frame = frame+1;
else frame = 1;
end
subplot(2,2,1); imshow(vid1(:,:,:,frame1));
if frame1 < size(vid1,4)
frame1 = frame1+1;
else frame1 = 1;
end
subplot(2,2,3); imshow(vid2(:,:,2,frame2));
if frame2 < size(vid,4)
frame2 = frame2+1;
else frame2 = 1;
end
subplot(2,2,4); imshow(vid3(:,:,:,frame3));
if frame3 < size(vid1,4)
frame3 = frame3+1;
else frame3 = 1;
end
drawnow;
if f4 > 500
break;
else f4 = f4+1;
end
end
then,I want to use button that control video.
Everyone video has two buttons(play,stop), so I have four videos,I must have eight buttons that control video,and set up one button controling "close" figure.
So,total of nine buttons,I must how to do.

You do not need separate play and stop buttons: you can use a single "radio button" that changes labels between "play" and "stop".
