HDR10+ (with NVEnc)

[Selur]

I did test is a while back and then it worked, just tested now with:

ffmpeg -y -loglevel fatal -noautorotate -nostdin -threads 8 -i "F:\TestClips&Co\files\HDR\HDR-10+\muxing\without HDR10+ data.mp4" -map 0:0 -an -sn -vf zscale=rangein=tv:range=tv -pix_fmt yuv420p10le -strict -1 -vsync 0  -f yuv4mpegpipe - | NVEncC --y4m -i - --fps 24.000 --codec h265 --profile main10 --level auto --tier high --sar 1:1 --lookahead 16 --output-depth 10 --vbrhq 0 --vbr-quality 0.00 --max-bitrate 240000 --gop-len 0 --ref 3 --bframes 0 --no-b-adapt --mv-precision Q-pel --preset default --colormatrix bt2020nc --cuda-schedule sync --dhdr10-info "F:\TestClips&Co\files\HDR\HDR-10+\muxing\HDR-10+.json" --output "E:\Temp\without HDR10+ data_19_21_35_1310_01.265"

and NVEncC just closed and echoed:

(also created a 0 byte large file)
-> seems like there's a problem with NVEncC or current NVIDIA drivers.

Ps.: You should probably report the issue with a command line and files for him to reproduce to the NVEncC author over at https://github.com/rigaya/NVEnc/issues
