[FFmpeg-user] configuration for installing with cuda

[hassan panahi]

Hello,
I recently bought a embedded board (banana pi-m64 )  .
And install ubuntu 16.04 from this link.
I want to install ffmpeg with cuda configuration for using hardware
acceleration (encode and decode h.264).
But return this error:
ERROR: cuda requested but not found

The command is:
./configure  --enable-cuda --extra-cflags=-I/usr/local/cuda/include/
--extra-ldflags=-L/usr/local/cuda/lib64/

Also i installed this version of cuda:

cuda_6.5.14_linux_aarch64_native.run

What's the problem?
My main goal in use hardware acceleration of this board with ffmpeg...
How can i do that?
tnx
