By using computervision toolbox I'm trying to play a video in MATLAB using this code, but only one frame is displayed on the window

a = vision.VideoFileReader('spur gear.avi' , 'VideoOutputDataType', 'double');

while ~isDone(a)

vidFrame = step(a);

c = imresize(vidFrame, 0.5);

imshow(c);

end

release(a);

You could do the following:

a = vision.VideoFileReader('spur gear.avi' , 'VideoOutputDataType', 'double');
VideoPlayer = vision.VideoPlayer
while ~isDone(a)
  vidFrame = step(a);
  c = imresize(vidFrame, 0.5);
  step(VideoPlayer,c)
end

release(VideoPlayer);
release(a);
