You have x264 installed from rpmfusion. They are (I think) based somewhere 
where software patents aren't valid, so they are free to include patented 
codecs that fedora can't. You have linphone installed from fedora. When fedora 
compiled linphone they didn't enable the x264 support because they don't want 
to be sued for patent infringement. Rpmfusion don't seem to have a linphone 
package, so you need to compile your own, or find a precompiled one somewhere 

If you use yum and rpmbuild it should sort most of the dependencies out for 
you. It's a while since I've done it - mainly a gentoo user now - but the 
instructions on the web weren't too hard to follow. You would need to change 
the config options in the spec file to enable the video codecs. A quick search 
turned up these two, but a quick search should find more.
