Comment 4 for bug 537617

security is a concern for universe as well, and is my main concern.

I've talked to Reinhard (ffmpeg upstream) now, and he told me that security is well maintained for Google's branch.
Also I've been told that the -mt branch will get merged to ffmpeg main at some point, but most probably not for 0.6.

That said, I'm ok to grant the FFe, given that you can convince an archive admin to new the package.

(side note: Reinhard suggested to rename the -nonfree package, since it doesn't contain non-free software. Maybe you could follow suite with the ffmpeg package and name it -extra?).
