Can't you expand pixeutils instead? Adding a new set of functions that
work on lines rather than blocks.
That is kind of intentional, because it is only used by libavfilter, so I
did not want to bloat libavutil with it. Also if I put it into libavutil
then the interfaces have to be public. I tried to avoid that because for a
generic scene SAD function bitdepth is not enough, you need endianness,
float/int color support, etc. Public API should be finalized when
something actually uses it IMHO.
I plan to push this soon.
Regards,
Marton
