Error nvenc 0x3e7 (999) Encoding ffmpeg (Ubtuntu 14.04)

Hi…

  I've tried encoding with ffmpeg but always have the same error when it started with video encoding part..

“>> dl_fn->cu_init(0) - failed with error code 0x3e7”

I followed all the instructions to compile ffmpeg (according to FFMPEG WITH NVIDIA ACCELERATION ON UBUNTU LINUX) using the cuda sdk 7.5 and my nvidia driver version it’s 352.63 so everything looks fine

lsmod | grep nvidia
nvidia 8642880 44

I don’t know what’s could be wrong or if there are something miss… and also I’m looking for the cuda error codes and didn’t found any information about that…
