<DIV></DIV>
<DIV>I found the x264's bug.</DIV>
<DIV> </DIV>
<DIV>encoder/anaysyse.c...</DIV>
<DIV> </DIV>
<DIV>static void x264_mb_analyse_inter_p16x16( x264_t *h, x264_mb_analysis_t *a ) </DIV>
<DIV>{</DIV>
<P><FONT style="BACKGROUND-COLOR: #ffffff"> double f64Data=0;</FONT></P>
<P><FONT style="BACKGROUND-COLOR: #ffffff"> f64Data = f64Data + 2;</FONT></P>
<DIV>}</DIV>
<DIV> </DIV>
<DIV>In X264, I declared double type variable.</DIV>
<DIV> </DIV>
<DIV>Whe the function is called in first, f64Data's value is 2.</DIV>
<DIV>But the fucnion is called in second, f64Data value is crashed !</DIV>
<DIV> </DIV>
<DIV>And I decalred int type variable.</DIV>
<DIV>
<DIV>static void x264_mb_analyse_inter_p16x16( x264_t *h, x264_mb_analysis_t *a ) </DIV>
<DIV>{</DIV>
<P><FONT style="BACKGROUND-COLOR: #ffffff"> int n32Data=0;</FONT></P>
<P><FONT style="BACKGROUND-COLOR: #ffffff">n32Data = n32Data + 2;</FONT></P>
<DIV>}</DIV>
<DIV> </DIV>
<DIV>Above the source code is good. First, second, third... good</DIV>
<DIV> </DIV>
<DIV>I don't know the above problem.</DIV>
<DIV> </DIV>
<DIV> </DIV>
<DIV>Best regards.</DIV>
