alternative to step24:
for VFW there's also an installer folder located in wfv/installer.
to compile the installer script (x264-conf.nsi) you need to download and install NSIS version 2.xx from
http://nsis.sourceforge.net/ .
Once you installed NSIS just righ-click the x264.conf.nsi script and select "Compile NSIS script".
Then, when finished, double click the .exe file and you get x264 VFW installed with start menu entries for configuration and uninstall.
