I apologize for the previous letter, I forgot to translate)
Dear developers. I simply wrote a patch, tested its operation on Intel with Hevc Rext support by decoding on all possible HEVC formats - 420 12bit, 422 8/10/12bit, 444 8/10/12bit.
There is no particular desire to describe why exactly this or that way.
But it is now in full working order, and the correct AV_PIX_FMT_ +  DXGI_FORMAT_ is registered in it, 
and copying from the GPU works correctly.
You can compile and test it yourself and make sure that everything works correctly.
 
Right here:
    (sps->intra_smoothing_disabled_flag << 5) | (sps->high_precision_offsets_enabled_flag << 5)
apparently yes, a typo, must be
    sps->high_precision_offsets_enabled_flag << 6
