According to my tests, it inserts a scaler for XVideo pictures and distorts 
the pixels by inverting the resolution:

swscale filter debug: 600x800 (600x800) chroma: YUY2 -> 600x800 (800x600) 
chroma: YUY2 with scaling using Bicubic (good quality)

This is clearly wrong; a transform filter is needed but no scaler.
