VP9 is on its way to be merged. There is a pull request from Hans
already: see https://www.spinics.net/lists/linux-media/msg202448.html
which includes the git repository and tag you can merge/rebase to test
it.
It would be great if you can test G2 on top of that, but it's also fine
if you want to just submit G1 for now. Up to you.
Regarding HEVC, currently Benjamin is who knows best how to test it.
Thinking about it, perhaps we should document this somewhere?
