How can i read a video and convert the first frame into an image?

img=VideoReader(filename);

P=img.Path;

nFrames=img.NumberOfFrames;

for k=1

 eikona=read(img,k);

 %figure(1),imshow(img,[]);
end

image1=getframe(image(eikona));

[X,Map]=frame2im(image1)

i use this code and i have this error: A valid figure or axes handle must be specified

See my attached demo where I save out all frames. You can adapt it to quit just after 1 frame if you want.
