 source on an random git type site and I have no idea how to use such file
 or if it works but I found that the FFmpeg has the "widevine.c" file in an
 libav folder or somesort.

 The second link (first one required a subscription) contained a hacked
 version of FFmpeg SVN rev19089 containing a wrapper to some proprietary
 library, and as is is an ugly hack which cannot be upstreamed.

 Note that widevine.c is implemented as a protocol, so it should be
 considered a protocol which allows to encrypt content (probably through
 DRM or similiar). AFAIK no effort was done by anyone of the FFmpeg team to
 reverse engineer the protocol format. Today I heard about partially
 encrypted files which can be played for the first few seconds (having such
 sample may help).
