I have just installed the latest nvidia driver.

I'm on laptop. Both the game xonotic, and obs studio 64 are run on the nvidia card.

[NVENC encoder: 'recording_h264'] Failed to open NVENC codec: Generic error in an external library

Why not? Am I missing something? Some forum/reddit says that it doesn't even has NVENC. They say just GTX card has those. It is truth for HEVC, but according to these my card (and some others) has NVENC:

https://en.wikipedia.org/wiki/Nvidia_NVENC#Second_Generation_.28Maxwell_GM107.2FGM108.29

https://developer.nvidia.com/nvidia-video-codec-sdk#SupportedGPUs
((GM10X) Maxwell H.264 encoding Yes)

https://www.bandicam.com/support/tips/nvidia-nvenc/
(H264 (Nvidia® NVENC) - Laptop GPU: GTX 660M, 670MX, 675MX, 680M, 700M or higher graphics cards.)

http://www.notebookcheck.net/NVIDIA-GeForce-840M.105681.0.html
(video encoding via NVENC API)

So OBS can't handle it, or something else?

I tried with ffmpeg, but wasnt able to use it.

Just tried, it is not showing up in bandicam.

Pardon, but that is not really convincing me. It seems for me it is absolutely supported by my system. Or actually, my card.

If you are still not convinced,
please install Geforce Experience and Nvidia will tell you that shdowplay is NOT supported by your card.
The 840M is from "GeForce" line. But you need a "GeForce GTX" as i mentioned in my 1st post already.

VanDuits, you rigth. Need GTX for shadowplay. Though I still do not need it. I would like to use NVENC, not shadowplay.

Harold. Than say it if it feels right for you. Though it is very simple logic. Once i wasn't able to get my sound working. So it wasn't supported then? Not in any.. music player.

It is okay if You can not help, that happens...

I was just talking with the nvidia guys, they say that it should work and that I should talk with the application developers to see if there is something that we are missing.

Any better place to ask the OBS developers about the issue than this forum?
