Dear Intel GPU community
i have Intel UHD 620 Graphics processor and according to the specification this type of GPU does support HEVC decoding.
However, a list of supported decoders supplied by DXVA2 utility GetDecoderDeviceGuids does not contain HEVC decoder GUID (5b11d51b😞
GUID ee27417f - mpeg2 decoder
GUID bf22ad00 - mpeg2 decoder
GUID e07ec519 VC-1 variable-length decoder 2 (not mentioned in dxva2api.h file )
GUID bcc5db6d VC-1 variable-length decoder (not mentioned in dxva2api.h file )
GUID 1b81bea4 - vc1 decoder
GUID 1b81be68 - h264 decoder
GUID d79be8da - H264_VLD_Stereo_Progressive_NoFGT
GUID f9aaccbb - h264 stereo
GUID 705b9d82 - h264 multiview
GUID 91cd2d6e unknown
GUID 90b899ea unknown
GUID 442b942a unknown
GUID 8c56eb1e unknown
GUID 75fc75f7 unknown
GUID 463707f8 vp9
GUID a4c749ef unknown
GUID 76988a52 unknown
GUID 80a3a7bd unknown
GUID a74ccae2 unknown
GUID 1b81be94 - WMV-9 decoder
GUID 1b81bea2 - vc1 decoder (mode C)
GUID 49761bec - unknown
Therefore i am suspicious whether Intel UHD 620 GPU support HEVC decoding?
In addition, in the above list there are unknown decoders (i.e. not mentioned in https://gix.github.io/media-types/ ).

Thanks David
Frankly speaking, upon restarting my laptop DirectX succeeds recognizing hevc hw:
found hw support: guid[5b11d51b-2f4c-4452-bcc3-09f2a1160cc0]
hw acceleration enabled - decoder[H265] format[NV12]
Have you a test program to decode hevc-stream?
