Hi, I've tried -vop scale -ssf ls=X with X=0,0.1,0.001,1,2,3,4,5... and with 0..4 i see no difference, with 5 and above it kills luma (only chroma visible). maybe a bug? :) or i misunderstood sth? A'rpi / Astral & ESP-team -- Developer of MPlayer, the Movie Player for Linux - http://www.MPlayerHQ.hu
