[Blink] ffmpeg dependency

[Mike Nagie]

Hello,

I'd like to ask you about the dependencies of the Sipsimple.
I try to maintain the Arch PKGBUILD
( https://aur.archlinux.org/packages/python2-sipsimple/ )
and ffmpeg was reported to cause problems.

Comments are visible on the page but here's the bottom line:

This happens when only ffmpeg (3.1.2) is installed.

ImportError: libvpx.so.3: cannot open shared object file: No such file 
or directory



And only with ffmpeg2.8:

aconfigure: error: *** Error: libavformat not detected ***



So which version of ffmpeg is suggested, or both ffmpeg and ffmpeg2.8 
are really needed at the same time?

Thank you
Mike
