After installing ubuntu 15.10 with nvidia-364 from graphics-drivers ppa:

NVENC 6.0 SDK Sample on compilation, running with this command:  
./NvEncoder -i …/common/video/plush1\_720p\_10s.m2v -o hello.avi -size 1280 720

Gives:  
NvEncoder: …/common/src/NvHWEncoder.cpp:506: NVENCSTATUS CNvHWEncoder::NvEncOpenEncodeSessionEx(void\*, NV\_ENC\_DEVICE\_TYPE): Assertion `0’ failed.

NVENC 4.0 Linux SDK on the command :  
bash 1080p\_heavyhand\_3sec.sh  
Gives :

Can someone help?

Some info (from ffmpeg):

```auto

You might need to update your nvidia driver to at least 384.xx if using the latest ffmpeg/nvenc
