[MPlayer-users] vop scale differences on mencoder / mplayer

[Chris Phillips]

Hi,

fiddling with mencoder and mplayer and the vop system. something like:

mplayer -dvd 1 -aid 128 -vop scale=-1:-2,crop=720:430:0:74

shows a title at 1024x302, while a mencoding with a similar line:

mencoder -ovc lavc -lavcopts vcodec=mpeg4:vhq:vqmin=2:vbitrate=768 -dvd
1 -aid 128 -o rip.avi -vop scale=-1:-2,crop=720:430:0:74

produces an avi at 720x302. Now i'm half expecting someone to lay into me 
about using -1 and -2 :P , but surely this effect shouldn't occur? I 
can't see any conceptual difference here. Can anyone else?
