With X11 and ffmpeg (so, probably Linux):

    ffplay -f x11grab -video_size 96x32 -framerate 10 -i :0.0+0,1048 -vf

will embiggen the bottom left pixels of a 1080p display.  Add some
swscaler flags to not make it blurry, perhaps, though youtube will
probably blur it for you again. Read `man ffmpeg-filters` for that.
