Nice catch. I checked last week and there was still nothing. At least
putting the structures in MSDN makes it a lot easier. The GUIDs were
already found in the D3D12 doc .
There seem to be bugs in their doc on
DXVA_PicParams_AV1.segmentation.feature_mask as the union names are
Some other changes:
- the Reserved16Bits fields are now a UINT16.
- fields in DXVA_Status_AV1 have lost their 'b' and 'w' prefix.
The original patch submitted got this build job
But it seems gone from the database (too old?).
I'll submit a revised version. It still builds when used in libavcodec .
