Been a while since I last broke all your packages, but fear not for the new ffmpeg has arrived :)

libavcodec.so=59-64 | libavcodec.so=60-64
libavdevice.so=59-64 | libavdevice.so=60-64
libavfilter.so=8-64 | libavfilter.so=9-64
libavformat.so=59-64 | libavformat.so=60-64
libavutil.so=57-64 | libavutil.so=58-64
libpostproc.so=56-64 | libpostproc.so=57-64

Packages to staging as usual, hopefully this time we won't need another compat package.
