Got HW Transcoding to work with libva/vaapi on Ryzen APU (Ryzen 7 4700U)

ALL:

Pulling together the results from those who’ve participated so far,
as well as the Better-Than-Expected results,

We have identified a few issues and most of those are fixed.
There are a couple more still pending.

We’re going to wait for Engineering to complete the current in-process corrections.
Once done, we’ll increase the scope to include more.

Heartfelt thanks to everyone who’s given their time to work with us on this to this point.
