mplayer 160x128.mpg -sub test.srt -xy 3


mplayer 160x128.mpg -sub test.srt -vf scale=512:384

well if you have a small video, the subtitles will be scaled automatically
to the video window (e.g. 160x128 video, with subtitles, then hit fullscreen).
the subs will be scaled again, but it will be scaled from the first scale,
instead of rescaled to new res, resulting in very jagged and crappy looking subs.

maybe subs need to be rescaled when video res changes? e.g. dynamic sub scale?

this method above would work always, at any video res, without scaling.
new attached patch will just scale the video first, instead of subtitles.

i dunno which is better or if either need to be in the FAQ..
