Fedora doesn't use any proprietary codecs so the ffmpeg stuff isn't
built and in fact we strip some of the codecs out of opal because of
their non-free status so ffmpeg is not a problem I ever have to deal
with. We explicitly remove the directories "plugins/video/H.263-1998/
plugins/video/H.264/ plugins/video/MPEG4-ffmpeg/" before we upload the
tar file into Fedora's build infra. I once asked upstream whether we
could split them out into a non-free tar file release or even ship
them separately but disappointingly got hailed down.

Anything we do to the vanilla upstream is in the git repos here.

Sounds like linker related bits. What distro are you using?

I suggest getting it building with out ffmpeg first in your
environment so you know the basics work and then add ffmpeg to a
configuration that you know is working.
