HEVC QVBR mode doesn't follow set --qvbr-quality value

[DimkaTsv]

Can i ask question? Or report bug, if it is such.
HQ-VBR, HQ-CBR and QVBR modes are actually also available for HEVC, not just AVC/AV1 as stated in documentation (as well as VBR-LAT, which isn't supported by VCEEncC, it seems?), and, while HQVBR and HQ-CBR get control via bitrate, as they basically use same flags, for HEVC QVBR specifically --qvbr-quality flag doesn't do anything, and encoder defaults to 23 (which is actual default for this parameter by AMF documentation), It does work for AVC QVBR though... And, probably, for AV1, but i cannot test it

Link to AMF documentation, proving that these 3 encoders are implemented for HEVC. VCEEncC also doesn't error out, so, there is that also.

Used command
,\VCEEncC64.exe -i "C:\Users----\Videos\Radeon ReLive\Black Desert Online\Test_video.mp4" -o "Test_video_processed.mp4" --codec hevc --profile main --level 5.2 --preset slow --ref 4 --ltr 3 --pa --qvbr 10000 --qvbr-quality 51 --audio-copy

Number 51 is just for show, it doesn't work for ANY value. And 51 should be possible to set anyways, right?

VCEEnc 8.18 should have fixed this problem, now --qvbr-quality value will be reflected also for HEVC encoding.

Can confirm fix in VCEEncC 8.18
