This directory contains files used in goanna builds from FFmpeg
(http://ffmpeg.org). The current files are from FFmpeg as of
Release 3.4.8
Release 3.4.9
All source files match their path from the library's source archive.
Currently, we only use the vp8 and vp9 portion of the library, and only on x86
