It could be interesting to "grab" this function from Av1an by @master-of-zen:

Segmenting

--split-method          Method used for generating splits.(Default: av-scenedetect)
                        Options: `av-scenedetect`, `none`
                        `none` -  skips scenedetection.

-m  --chunk-method      Determine the method in which chunks are made for encoding.
                        By default the best method is selected automatically.
                        [possible values: segment, select, ffms2, lsmash, hybrid]

-s  --scenes            File to save/read scenes.

-x  --extra-split       Size of chunk after which it will be split [default: 240]

--min-scene-len         Specifies the minimum number of frames in each split.

Hope that inspires.

The code not working, unable to encode with GPU

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.
