its possible, but we need to define exactly what the api should
return. do you just want quantizers? or are dc/ac coefficents also
useful? i dont know much about post processing.

i really think someone should develop a  libpostproc, which takes
an image + quantizer/coeffs-array, and performs post processing.
that way, all decoders xvid,ffmpeg,libmpeg2,etc. could benefit.
