as you can see Changelog of libvpx:
  - Upgrading:
      This release is ABI incompatible with 1.4.0. It drops deprecated VP8
      controls and adds a variety of VP9 controls for testing.
      The vpxenc utility now prefers VP9 by default.
so we have turn it off till ffmpeg* should reflect this reariry,

or someone(TM) who ring a bell provide a these patch for it ?
