RPM would refuse to do that if any installed package requires the
library from the freshrpms' x264 package. If any of the installed
packages requires libx264.so.55 from the freshrpms pkg, you cannot
downgrade the x264 package to livna's version because it only contains
the newer libx264.so.56 library. :)
