Hi, i'm think this will be helpful and no need to use NVHSP:
ffmpeg -hwaccel cuvid -y -i /storage/input_HDR.mp4 -c:v
nvenc_hevc -pix_fmt p010le -color_primaries 'bt2020' -colorspace 'bt2020nc'
-color_trc 'smpte2084' -preset slow -level 5.1
-b:v 20000000 -rc vbr_hq -crf 22 -c:a copy /storage/Out/testHDR_NVENC.mp4
And how i know, nvenc doesn't have eqivalent "crf". No need to use -crf.
For nvenc rate control options:
-rc <int> E..V.... Override the preset rate-control
(from -1 to INT_MAX) (default -1)
constqp E..V.... Constant QP mode
vbr E..V.... Variable bitrate mode
cbr E..V.... Constant bitrate mode
vbr_minqp E..V.... Variable bitrate mode with MinQP
(deprecated)
ll_2pass_quality E..V.... Multi-pass optimized for image quality
(deprecated)
ll_2pass_size E..V.... Multi-pass optimized for constant frame
size (deprecated)
vbr_2pass E..V.... Multi-pass variable bitrate mode
(deprecated)
cbr_ld_hq E..V.... Constant bitrate low delay high
quality mode
cbr_hq E..V.... Constant bitrate high quality mode
vbr_hq E..V.... Variable bitrate high quality mode
