Greetings,

Within my OBS Studio Settings, I'm trying to enable NVENC encoding for my recordings. However, when I attempt to record, I receive the following error:

obs_fail.png


My system information
(for a more information, here is my MSConfig Excerpt)
Relevant OBS Studio information
(please refer to this OBS Studio Log which is more complete)
  • A number of "Required module function 'obs_module_load' in module.." errors
  • A few "Failed to open NVENC codec" errors
My main comments and questions

My research stalled as I found a number of conflicting data-bits. What I do know is that, according to NVIDIA, my card does support NVENC encoding. But it's not clear to me if there's some additional driver I require (although I'm 99% sure I have all up-to-date drivers on my system).

Also, I can't find the link now, but it has been suggested (at least as a minority opinion) that I should watch my ram use, since NVENC requires a large amount of it. It is not clear to me what constitutes 'a lot' and I'm hesitant to buy another stick of 16 until I've better nailed down this issue. What I do know is that I've disabled every large application before recording.

Any information at all would be quite appreciated. Thanks for your attention.

Which Nvidia driver are you on? You might consider doing a clean re-install of the latest, as hinted by the error message.

Also change your NVEnc Preset to High Quality or High Performance. Don't use Default.

You have 16GB of RAM so that is absolutely fine. I encoded with NVEnc on my old stream box with 4GB.

Your log shows this:
  1. 14:59:20.635: error: Cannot load NvEncodeAPIGetMaxSupportedVersion
  2. 14:59:20.635: [NVENC encoder: 'streaming_h264'] Failed to open NVENC codec: Unknown error occurred
That error message means you don't have the right driver installed. You need to update it to version 368.69 and higher. Go to Nvidia and download the GeForce Experience application to automatically update:

I'm pretty late to this one, but still: Thanks. I will investigate further. I actually installed GeForce Experience but wasn't able to do anything before. (Mind is hazy though). I will give it another go!
