[MPlayer-users] [Patch] moving the picture around the screen

[Mark Zealey]

I wrote a patch that lets you move the image around the screen so rather than
being in the top-left the whole time you can put it anywhere on the screen. At
the moment i have only changed the tdfx driver, but it is a very trivial change
to any other driver. You change the position by using a -xper and -yper and
giving it a percentage, eg -xper 100 -yper 0 would be top right. Patch is
attached, if people could review it, I'll then commit it to cvs or so.
