[MPlayer-users] newbie: how can I rotate an .avi and preserve the file type/codecs

Yes, read better the documentation, -vop options are in reverse order, so you
should do mencoder -vop scale=720:576,rotate=2
in order to do first the rotation, and after that the scaling over the rotated
image. I have just tried it on a video and it works.
