Description
Hi,
I'm using a great program FFMPEG with support for HEVC_NVENC 10bit and HWACCEL CUVID, but I ran into this problem: I can't set the parameters Light level Maxcll and Max fall, this is necessary to correctly transmit the brightness of the HDR content (I can't find anywhere on the Internet How to write these parameters correctly).
Here's my line.:
ffmpeg -loglevel debug -threads:v 4 -threads:a 8 \
-hwaccel cuvid \
-i "/run/media/helg/WDC/HLG.mov" \
-b:v 40M -maxrate:v 50M -rc vbr_hq -2pass 1 -c:v hevc_nvenc -preset slow -sei hdr -profile:v main10 -level:v 5.1 \
-color_primaries bt2020 -color_trc arib-std-b67 -colorspace bt2020nc -color_range tv -maxcll 1000 -maxfall 100 \
-flags -global_header -max_muxing_queue_size 1024 \
-c:a aac -b:a 384k \
-f matroska -y "/run/media/helg/WDC/HLG.mkv"
The terminal returns an error: Unrecognized option 'maxcll'.
Please tell me what I'm doing wrong?
(my system: Manjaro Linux, GeForce GTX 1050ti, ffmpeg version n4.2.3 )

a simple google search yielded

-maxcll "1000,300"
which does not look like yours ?

I forgot to write at the beginning that this is what I need to develop the program in the Linux environment. The fact is that the described method using "nvhsp" only works for Windows. And it turns out that at the moment it is impossible to develop a full-fledged application for Linux, I see this as a problem.

Maybe patch below can meet your command.
https://patchwork.ffmpeg.org/project/ffmpeg/patch/20201229035649.5612-1-kloblic@gmail.com
ffmpeg command:
ffmpeg -i HDR_X265_master2.mp4 -vcodec hevc_nvenc -bsf:v hevc_metadata=transfer_characteristics=16:colour_primaries=9:video_full_range_flag=0:matrix_coefficients=9:max_cll="1000|1000":master_display="G(13250|34500)B(7500|3000)R(34000|16000)WP(15635|16450)L(10000000|100)" with_sei_video_265.mp4 -y

Meanwhile dolby vision decoding is done (no dynamic metadata, no EL decoding yet) and this one is nice: https://patchwork.ffmpeg.org/project/ffmpeg/list/?series=6307
This will allow to color manage D93 to D65, e.g., when dealing with BT.1886 anime from Japan that uses different ambient light.
