NVENC not working on Nvidia 930M

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

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 :

NVENC error at src/CNVEncoder.cpp:1874 code=2(NVENC that devices pass by the client is not supported) “nvStatus”

Can someone help?

Bump, cuda/nvenc not working on gt 930m for me too. NVENC fails with 0x2 error.

Some info (from ffmpeg):

Nothing useful anymore ;(

I have the same problem… Is there any solution?

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