--qstep <integer>，--qblur <float>，--cplxblur <float> didn't work

--qstep 5 would make the encoding crash.

And other settings didn't have any effect.I tested --qblur 0，--cplxblur 0,--qblur 0.5，--cplxblur 10,--qblur 0，--cplxblur 10 etc,and those outfile have the same md5 as the default settings.

Other settings during the testing. --preset veryslow --crf 15.5 --tu-intra-depth 3 --tu-inter-depth 3 --me 3 --subme 5 --merange 25 --b-intra --no-rect --no-amp --ref 5 --weightb --keyint 900 --min-keyint 1 --bframes 9 --b-adapt 2 --aq-mode 1 --aq-strength 1.1 --rd 5 --no-sao --no-open-gop --rc-lookahead 72 --scenecut 40 --max-merge 4 --qcomp 0.8 --no-strong-intra-smoothing --pmode --pme --psy-rdoq 4.0 --psy-rd 0.9 --deblock -2:-2 --rdoq-level 1

--qstep should be --qpstep, I've fixed the docs. the others are only used by certain rate control modes.

pme is usually a waste of time, and you probably want SAO enabled if you are encoding veryslow, it's an important quality feature.

OK thanks for your answer.
