I would urge you to use y4mtoppm :

lav2yuv movie.avi | y4mtoppm -L | pnmsplit - image-%d.ppm 

(if you have progressive frames you dont need -L )

Well, this gives you ppm frames, but you can easily convert those
ppms to jpegs if need be. Although I have previously extracted valid jpeg
frames using lavtrans, it never worked the way I expect it to..
