-mbd, -cmp, -subcmp ? As far as I am aware (and I quickly skimmed the source
that I updated...) those three switches will do nothing, except for -cmp
which may affect chroma depending on its argument. The me_method switch
affects the ME search method/pattern (dia, hex, umh, esa are available) but
the 'cmp' functions are fixed internally. With regard to -mbd 2, which
enables RD MB decision, there's the -subq 6 and 7 which use RDO for ME and MB
decisions and -flags2 +brdo to enable RDO for b-frames.
Also, this message might be of use (though all flag switches require arguments
and I didn't know this at the time):
