Hello everybody,
I am trying to use FFMPEG ( 3.4 version) to transfert HDR video
specifications (x265.mp4 videos). I have seen on other forums command lines
that I tried to test for me but I never have succesfull results. I want to
use Nvidia options (NVENC/SCALE_NPP/or other) because I have a P4 graphic
card.
Here is my file (Media Info)

And here is the command that I tried:
time /FFmpeg/3.4/bin/ffmpeg -hwaccel cuvid -c:v hevc_cuvid -i
/storage/input_HDR.mp4 -c:v nvenc_hevc -filter_complex
[0:0]scale_npp=colormatrix=bt2020:h_chr_pos=0:v_chr_pos=0,format=yuv420p10le
-pix_fmt yuv420p10le -x265-params
"colorprim=bt2020:transfer=smpte-st-2084:colormatrix=bt2020nc" -crf 22 -c:a
copy /storage/OUT/testHDR.mp4
When I ran the command I have this error message

Why I cannot use the colomatrix option?
/PS:I have tried with "scale_cuda" and it didn't work too./
