I am trying to save frames from live stream after each 5 seconds duration and save the frames as an image into the folder. Kindly tell me how to define the n number of frames of live stream cam here?
Please help me to solve this problem.
Folder = 'OUTPUT\';
vid = videoinput('winvideo', 1);
% wait for 5 seconds
for iframe = 1
frames = getsnapshot(vid);
pause(5);
imwrite(frames, fullfile(Folder, sprintf('%06d.jpg', iframe)));
end

You can use a while loop here.
Folder = 'OUTPUT\';
vid = videoinput('winvideo', 1);
% wait for 5 seconds
while true
frames = getsnapshot(vid);
pause(5);
imwrite(frames, fullfile(Folder, sprintf('%06d.jpg', iframe)));
iframe = iframe + 1;
end
Hope this does it.
