Comment (by Andrew-R):

 Replying to [comment:41 Balling]:
 > Well, again. Color_range 2 does not work as input option and that is not
 how you handle ranges, you use -vf scale=in_range=pc:out_range=pc

 well, but why color_range has no effect on input (in this case reading
 from lavfilter test source)? Is it stated in documentation? I think in my
 case autoscale tries to insert right flags, of course it may fail. At
 least colorspace seems to propagate from input ...
