[BUG] x265 psyrd default value

[andrewschen]

Apply a preset whose default psyrdoq value is 1

Can you tell me one?
Because looking at: http://x265.readthedocs.io/en/default/pr...ml#presets
There isn't a preset which sets '--psy-rdoq'.
So applying any preset will set  '--psy-rdoq' will set 'psy-rdoq' to the default value which is 0.0:

  --[no-]psy-rdoq <0..50.0>     Strength of psycho-visual optimization in RDO quantization, 0 to disable. Default 0.0

-> Still can't reproduce the issue.
But, I stumbled over some code which might cause your issue,..

Cu Selur

Tested the dev version file, x264 rc-lookahead and x265 psy-rdoq was all fixed.

I did read the Preset Option page before I submit this issue, and I thought maybe they just didn't list all the detail parameters in that page? since http://x265.readthedocs.io/en/default/cl...n-psy-rdoq here mentioned psy-rdoq should be 1.0 for presets slow, slower, veryslow. (And maybe placebo also)  

And I tested further in the dev release you sent, by just enabling/disabling 'x265->Misc->Random Stuff->Minimize command line' after applying each preset, some other parameters could still be switched on/off.

(Following order is Enable / Disable 'minimize command line')

ultrafast:
high-tier=1/high-tier=0 (I think this should always be 0 by default, since the default setting in Hybrid GUI is main tier)
deblock=0:0/no-deblock (don't know which is correct, is that deblock should be disabled in preset ultrafast?)
no-opt-qp-pps/opt-qp-pps (I think this should always be disabled by default?)
no-opt-ref-list-length-pps/opt-ref-list-length-pps (I think this should always be disabled by default?)

superfast, veryfast, faster, fast, medium, slow, slower:
high-tier=1/high-tier=0
no-opt-qp-pps/opt-qp-pps
no-opt-ref-list-length-pps/opt-ref-list-length-pps

veryslow:
high-tier=1/high-tier=0
rskip/no-rskip (should be no-rskip for preset veryslow)
no-opt-qp-pps/opt-qp-pps
no-opt-ref-list-length-pps/opt-ref-list-length-pps

placebo:
high-tier=1/high-tier=0
tskip/no-tskip (I guess this should always be no-tskip by default?)
limit-refs=0/limit-refs=3 (should be 0 for placebo)
no-opt-qp-pps/opt-qp-pps
no-opt-ref-list-length-pps/opt-ref-list-length-pps

For you reference. Maybe you can fix them at the same time?
