I have few problems with this spec file.This kind of miss my attention. This package violate our founding principle https://rpmfusion.org/FoundingPrinciples. Quoting: "Both repositories (free/nonfree) contain only add-on packages and not replacements in relation to the base package set. Whereby the base package set is defined as: RHEL/CentOS + EPEL or Fedora (Fedora 7+) " I'm about to remove theses from our repo without delay (on the next push). I'm suggesting to rework the packaging in a way that avoid replacing base "package". Please not that our principles doesn't forbid to replace any library. Here is my suggestion: - have chromium and chromium-freeworld - have fedora chromium install a symlink libffmpeg.so.fedora to libffmpeg.so (same for libmedia.so). using %version.0 as priority with update-alternatives - have rpmfusion chromium-freeworld install a libmedia.so.freeworld with %{version}.9 as a priority with update-alternatives.
