, so as I promised, I am releasing VAQ 2.0 for initial alpha testing. Thanks to Alex W for the basic concept behind VAQ 2.0! How to use (change from normal VAQ): --aq-metric presents four options for the AQ metric to use. Each is progressively slower than the last; option 0 is equivalent to VAQ1. Since the VAQ committed to official x264 has 1.0 strength as default (equivalent to 0.5 with unofficial AQ, since all values were doubled for simplicity's sake), 1.0 is default here also. Try playing with the different AQ metrics and strengths and testing the results. .
--aq-mode? Should it be by default fot this time of testing? Is r777 with VAQ 2.0 multhitreaded? It uses only one core of my e2160 while r798.modified (VAQ 0.48) use 2 cores. Code:
two side questions: 1. What in the value range allowed for --aq-strength? 2. Does --aq-strength 0.0 also disable adaptive quantization? Cu Selur Ps.: there's a 'new-line' missing before '--nr' (after metric options) when calling --long-help ;)
For those who are interested is diff which can be applied on the current git version (r808). Also I fix bug in x264_autosense_aq (incorrect use of h->mb.i_mb_x and h->mb.i_mb_y instead of mb_x and mb_y)

Here is a collection of tests I did on a couple of 4 second football clips. They are slightly worthless for comparison purposes because they are mostly different framesizes and different bitrates and CQ / 2pass / 3pass whatever. The only thing they have in common is they all use VAQ2 (using patched build based on r777)! Unless specified. So if you want a collection of slightly useless (for comparative purposes) encodes of football on a rainy imperfect pitch you can get them . Better comparisons in
Excellent job, MasterNobody. Thou art truly the master o'er bugs, o BugMaster. :) I will certainly give this a test soon. How is the speed on BugMaster's mod? Does it do the same thing as the original on 777?
