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.
