hmm, looks ok, but you should use strtol() for int parsing, instead of
reinventing the wheel, and use memcpy_pic() instead of reimplementint it
also filter could support YUV formats too, the packed ones (yuy2 etc) seems
quite trivial (handle same way as rgb16), but the planar yv12 is easy too
also the filter could support DR (by implementing get_image()), but we
discussed this on IRC with Rich, and out-of-order decoding may emss up the
whole thing, so it must be implemented in a very tricky/clever way.
i'll try to do that.

yes this is a known problem of the vf layer, not the only one :(
the next_config() wrapper tries to insert scale filter, but it doesnt always

yes, either 'make dep' (ro make depend) after ./configure (ala kernel),
or touch .developer in the source root dir
