x264

[Jarecki]

Hi,

encoder/analyse.c line 193
-p_cost_mv[a->i_qp][i]  = a->i_lambda * (log2f(i+1)*2 + 0.718f + !!i)  
+ .5f;
+p_cost_mv[a->i_qp][i]  = a->i_lambda * ((logf(i+1)/logf(2))*2 +  
0.718f + !!i) + .5f;

but something is strange in version numbers

this newly compiled version (x264-0.0.20090119)
# x264 --version
x264 0.50.x
built on Jan 26 2009, gcc: 4.2.1 20070719  [FreeBSD]

orginal FreeBSD port was (0.0.20080409 higher version???)
x264 0.59.x


linux
# x264 --version
x264 0.65.1058+5 d106962
