 This is the same bug as
 https://bugs.launchpad.net/ubuntu/+source/ffmpeg/+bug/386397
 
 As easy workaround, you can move /usr/lib/i686/cmov/libswscale.so.0 out
 of the way.
 
 Not sure how to fix this properly.

 By doing what the first comment in that bug report says?
 Compile FFmpeg with --enable-runtime-cpudetection

oh, I must have overlooked that. Yes, at the first glance, this seems
indeed the way to go. Thanks for pointing this out.

upon closer inspection, this is not possible in ffmpeg 0.5 yet. Unless
someone wants to work on backporting this change from current trunk, I
fear this will remain unfixed until ffmpeg 0.6.
