bugfixes: last 3 lines not brightness/contrast corrected
brightness statistics messed up with initial black pic changed initial values of the brightness statistics C++ -> C conversation QP range question solved (very likely 1<=QP<=32 according to arpi) new experimental vertical deblocking filter RK filter has 3dNow support now (untested) Originally committed as revision 2169 to svn://svn.mplayerhq.hu/mplayer/trunk/postproc

figure range of QP out (assuming <256 for now)

unroll stuff if instructions depend too much on the prior one

we use 8x8 blocks for the horizontal filters, opendivx seems to use 8x4?

move YScale thing to the end instead of fixing QP

write a faster and higher quality deblocking filter :)

do something about the speed of the horizontal filters

make the mainloop more flexible (variable number of blocks at once
