Media-driver may have some known issues as below for feature implementation due to hardware/API limitation or historical reasons.
Root Cause: Detail in PR/1162.
In media driver, we treat pFwdRef as future frame and uses pBwdRef as previous frame for ADI.
However, in VAAPI, we defines forward_references as past frames and defines backward_references as future frames.
Impact: Our ADI quality may be reduced because of this mistake.
Most of usages is in our internal tests. It does not impact a lot on our customers.
