I'd like to suggest another possible path, you could port the filters
to FFmpeg/libavfilter (which has no colorspace limitations), then I
could add a Frei0r plugin to apply libavfilter filters (I wrote a
frei0r wrapper in FFmpeg, I think it should be possible to do the
other way around). On the other hand I understand that native Frei0r
filters may be preferrable.

Regards.
