It might be worth letting that conversation finish before pushing
anything here. The API for VP9 hasn't changed, but there was a bug as
you pointed out in that thread.

> It is expected that VP9 ROI support will not be released in a short time, so I just add for vp8 roi.
> There is something common between VP8/VP9 ROI, and I plan to extract an common function when doing the work for VP9 roi.
