What is this ffmpeg dependency error telling me and how do I fix it?

At some point, I had an error with dependencies and had to remove some forcefully with pacman -Rdd libvpx libx264. I have since reinstalled them, however I get this error upon each yaourt -Syua: error: missing 'libvpx.so=4-64' dependency for 'ffmpeg0.10' error: missing 'libx264.so=148-64' dependency for 'ffmpeg0.10' Here is what I did to track down the problem ~ $ pacman -Qs libvpx local/libvpx 1.7.0-1 VP8 and VP9 codec ~ $ pacman -Qs libx264 local/libx264 2:152.20171224-1 Library for encoding H264/AVC video streams (8bit depth) I do not get the error when I run pacman -Syu.
