Hi
I use this command which fails with this error message

$ ./ffmpeg -init_hw_device cuda=0 -filter_hw_device 0 -i vid1080.mp4 -vf
 format=nv12,hwupload,scale_npp=1280:720 -c:v h264_nvenc 720p2.mp4

I get nv-code-headers from

$ git clone https://git.videolan.org/git/ffmpeg/nv-codec-headers.git
Modified PREFIX = /home/mahmood/nv_codec_headers
$ make
$ make install


Also, nvidia-smi shows
