Ok, well, for now, I should assume that hardware decoder silently fails,
without any indications. I tried DXVA2 Status reporting facility, it
reports that everything is OK.
I cannot surely say about any bugs in FFmpeg, I don't know if the HW
decoder fails because of FFmpeg sends it incorrect data or because data is
invalid per se.
So, thank you for very useful discussion, sorry for disturbance, I think,
this ticket should be closed now.
