What error message are you encountering and at what line?

Answer 1

It doesn't look like you're starting with an RGB image - it looks like you have this: YUY2_320x240. So why are you trying to convert it as if it were an RGB image with this line:

in=rgb2ycbcr(im);

You may be right, but I've not used cameras running in other than RGB mode.
