Scales the image with the software scaler (slow) and performs a YUV<->RGB colorspace conversion (also see -sws).
scaled width/height (default: original width/height)
NOTE: If -zoom is used, and underlying filters (including libvo) are incapable of scaling, it defaults to d_width/d_height!
0: scaled d_width/d_height
-1: original width/height
-2: Calculate w/h using the other dimension and the prescaled aspect ratio.
-3: Calculate w/h using the other dimension and the original aspect ratio.
