[FFmpeg-user] Problem configuring ffmpeg

[Mahmood Naderan]

Hi
When I configure ffmpeg with the following command

$ ./configure --enable-cuda --enable-cuvid --enable-nvenc --enable-nonfree
--enable-libnpp
--extra-cflags=-I/usr/local/cuda/include,../nv-codec-headers/include
--extra-ldflags=-L/usr/local/cuda/lib64

I get this error

ERROR: libnpp not found


As I search apt I see

$ sudo apt install libnpp
libnppc9.1     libnppicc9.1   libnppidei9.1  libnppig9.1    libnppist9.1
libnppitc9.1
libnppial9.1   libnppicom9.1  libnppif9.1    libnppim9.1    libnppisu9.1
libnpps9.1

By installing even all packages, I still get the same error.
Any idea to fix that?

Regards,
Mahmood
