First, I have to ask:
In your first mail, you indicated that despite your configure line,
your compiled ffmpeg does not support libvpx_vp9. In a subsequent mail,
you showed us a build failure. Those two don't match.
What is the result from this config.log you gave us? Does it fail when
linking, or does it successfully build an ffmpeg binary, but that
binary does not have libvpx_vp9 support?
That said: This config.log does its checks for libvpx_vp support
starting in line 11790, and it seems to succeed for both features.
If you get no error while building, I don't see why the resulting
ffmpeg shouldn't have libvpx_vp9 support. If you do get the mentioned
error while linking, your libvpx seems to be missing some symbols. This
can be either due to a miscompilation of said library, or due to some
recent changes to its API/ABI which ffmpeg can't cope with.
