Oh, sorry for the misunderstanding. I do have mpeg2enc installed and libmpeg2encpp.dylib in /usr/local/lib, only not latest CVS as quantisation is broken. In fact I mainly need mpeg2enc, and all distributions after 1.9.0rc1 do not work correctly. So I tried compiling yuvafps against 1.9.0rc1 and also against mjpegtools as of 2007-02-20 (last working mpeg2enc) but I still get the error I mentioned.
