VP9 GStreamer is merged, and building with the monorepo is really
really easy now.
The VP9 driver changes have been sent for merge,
see https://www.spinics.net/lists/linux-media/msg202448.html
which includes the git repository and tag you can merge/rebase to test
it.
Please rebase on that and make sure we don't have VP9 regressions
and update the commit description. This might sound annoying, but it is
what it is until we have CI in place.
Thanks!
