Hello,
When setting level of HEVC in NVENC, FFmpeg gives error:

Stream mapping:
Stream #0:0 -> #0:0 (h264 (native) -> hevc (nvenc_h265))
Error while opening encoder for output stream #0:0 - maybe incorrect
parameters such as bit_rate, rate, width or height
FYI: If I run;
root@encoder:~# /opt/ffmpeghw/bin/ffmpeg -i /root/bunny.mp4 -aspect 16:9
-s 3840x2160 -vcodec nvenc_h265 -preset hp -fflags +genpts -vb 25000k -
minrate 25000k -maxrate 25000k -bufsize 75000k -muxrate 25000k -r 50 -an
-flush_packets 0 -packetsize 188 -level 6.1 -y -f mpegts /dev/null
It works fine.
These values give error: 1, 2, 2.1, 3, 3.1, 4, 4.1, 5, 5.1, 5.2, 6,
