I'm trying to configure and replace libx264 encoder with h264_nvenc NVIDIA encoder.
I want to replace the parameter -x264-params ref=4 with it's parallel nvenc parameter.
I used ffmpeg -hide_banner -h encoder=h264_nvenc to see all available options but couldn't find any proper replacement.
Any advice?
It looks like in the latest ffmpeg source they added dpb_size parameter and it somewhat directly infulences refs parameter internally. Give it a shot.
