I see the problem, i dont know which solution is best but

qmax in mpeg2 depends on the use of non linear quantizer IIRC (unless i
have the place of where the max is applied wrong ...)
then most options depend on the profile & level, some might depend on
the pixelformat 420 vs. 422 vs. 444

So simple per codec ranges are not enough at all ...
