Error using frame2im Invalid movie: expected a structure

Hi all I have an avi movie. I use those code. What is wrong?

mov = VideoReader(videoname); frame = readFrame(mov); [img, ~] = frame2im(frame);

Error using frame2im Invalid movie: expected a structure

Thanks

As its documentation clearly states, the readframe function returns a numeric array already (i.e. an image), so you do not need frame2im at all. Remove frame2im from your code. frame2im is only required if you are using getframe (because it returns a structure).
