Is the ffmpeg implementation of swscaler essentially mplayer scaling?
does it allow for filtering?
If so, being able to create seperate scaling profiles would be great
to allow for filtering poor quality SD stations to a greater extenet
than high quality(ie digital) SD stations, and then even another level
I've played with this in mplayer before in doing transcoding of tv
shows (both SDTV of varying quality and HDTV to "hr.hdtv").
