Axel,
I compiled  todays tarball of x264 and it works. I only did a few minutes of
encode but at least it no longer segfaults and it is using cpu capabilities:
MMX MMXEXT SSE SSE2 SSE3 SSSE3 Cache64

I compiled the specfile  from ffmpeg-0.4.9-26_r12135.src.rpm with :
--without libnut --without libgsm

Let me know how else I could be of help

Thanks
Chris
