Note: none of this should be done as root unless otherwise specified. Create an RPM building environment for yourself: http://www.city-fan.org/tips/CreateRPMBuildEnvironment Download the SRPM Install the SRPM: $ rpm -Uvh /path/to/ffmpeg.src.rpm Edit the spec file to add the configure options you want: $ vi ~/rpmbuild/SPECS/ffmpeg.spec It's good practice to also change the "Release" number and add a changelog entry in the spec file when you wake changes. Rebuild the package: $ rpmbuild -ba ~/rpmbuild/SPECS/ffmpeg.spec At this point you may find that you need to install some additional -devel packages. These should be yum-able (as root). Paul.
