aq-strength not available in --zones

[fransky]

I did use --zones to tune aq-strength for some scenes once, and x264 didn't give any warning or errors. So I thought it works.

But lately a friend did some testing and found that the dump-yuv file with/without --zones aq-strength have the same MD5 hash. So it means aq-strength isn't tuneable in --zones but no error is given when used, nor any effect.

I wonder why aq-strength isn't allowed in --zones?

btw, imho, if it doesn't work, x264 should give some warning.

another little issue, whenever --zones is used. the warning about --ssim appears twice in the log, like this:

avs [info]: 1280x532p 0:0 @ 24000/1001 fps (cfr)

zones can't tweak AQ
You may use vfr_maniac's x264 MixAQ builds which could be more available for tweak AQ (but it's highly experimental...)

and in fact warings of PSNR/SSIM implementated until recently (maybe because it have no influence on output or who want to use --psnr/ssim should know it already), you may feedback it at http://forum.doom9.org/showthread.php?t=108571
