Ive added some -vf uspp (PP by (mis)using the snow codec) based images to pp vs. spp filters, the reason for uspp=6 instead of higher values is that higher ones wake the OOM-killer :-) the reason for the lack of pp=ac/ha/va based samples is that they look identical to the pp=de/hb/vb

Comparing the pp and spp filters from MPlayer/ffmpeg with the standard lena 256×256 image, the unfiltered one is a simple 10% quality jpeg saved by gimp
