Well, the way short_ref[] and long_ref[] are filled in indeed looks? 
like what is done for the DPB. However, (short_ref[] U long_ref[]) is? 
a superset of (RefPicList0 U RefPicList1). That's why I am now filling? 
ReferenceFrames[] wrt. ref_list[] only. This works for both VA API and? 

And, IIRC, it's probably what people do for DXVA too. Though, they? 
mention the other way around, i.e. RefPicList0 and RefPicList1 are a? 
subset of RefFrameList (ReferenceFrames in the Linux APIs).
