Other ffmpeg parameter not working?

[Duramoin]

Hello

Other ffmpeg parameters not working? Or I am doing wrong?

here is the modified command line

-c:v hevc_nvenc -vf scale=$RESOLUTION -map_metadata -1 -pix_fmt p010le -preset:v slow -cq $set_cq -b:v 0 -temporal_aq 1 -profile:v $set_profile -c:a aac -b:a 160k

.The -preset:v slow is working fine but if I changed it to -preset:v slowest or p7 or 18 (based on ffmpeg -h encoder hevc_nvenc) are not working. I mean when you press the play button to start the encoding, it just stops.

also the -b_ref_mode is not also working according to nvidia the Tesla T4 supports b frames.

Thank you and thanks for your work.
