Install from source over rpm
 

I have xvid and ffmpeg installed via urpmi on a Mandriva 10.2 Linux, but ffmpeg won't recognize xvid as a codec. I suppose that is because xvid is not enabled. I don't know if I can get an xvid enabled rpm or not.

Can I just install from source over the original rpm install or should I unistall the rpm and then do the source install?

Uninstall the RPM first if you want to install from source. First though make sure you've got win32-codecs installed and then try it again with the rpm installed ffmpeg
