[MPlayer-dev-eng] [patch] auto-scaling to square pixels in mencoder

Hi,

ok, i've moved few aspect-related options to cfg-common.h, as they work wiht
mencodre too since libmpcodecs.

now you can do -vop scale -zoom  (option -zoom enables scaling, just like in
mplayer, and -vop scale inserts software scaling plugin)
to get the same effect as your patch does with -vop scale=correctaspect

now you can also use -flip/-noflip in mencoder too

and i've changed -xy to keep aspect ratio, so -xy 512 will set width to 512
and set height to something to keep correct aspect ratio (288 for my 16:9 dvd)
