Hello, the source code of the rescaler states that it does
"High quality image resampling with polyphase filters"
I have done two tests by
gst-launch videotestsrc ! video/x-raw-yuv,width=320,height=200 ! ffvideoscale !
video/x-raw-yuv,width=160,height=100 ! ffmpegcolorspace ! ximagesink
and
gst-launch videotestsrc ! video/x-raw-yuv,width=320,height=200 ! ffvideoscale !
video/x-raw-yuv,width=640,height=400 ! ffmpegcolorspace ! ximagesink
In both cases, the picture is interpolated.

Why do you think that your setup does just nearest-neighbour rescaling?
