Legion 5 Pro NVENC error NV_ENC_ERR_UNSUPPORTED_PARAM

2021-04-08, 15:16 PM

Hi,

 

recording the screen with any application on my Legion 5 Pro doesn't work. For example in OBS I get the error I mentioned in the subject. It seems to be a problem with the NVENC. Does anyone else have this problem and has been able to fix it?

 

Cheers

Hello @Haenir,

 

Welcome to the Community Forums.

 

I checked the error message online and it seems this is fixable by changing the settings in the program you're using.

Kindly try running a search for the error code and it should show you a video on how to fix it.

Hope this helps.
Regards,
Jack_Lenovo1

Hello, I've tried but it is evident that the error is with the laptop. Also because I can't record my screen with any software, such as Geforce Experience, Overwolf or Xbox Game Bar.

I am having the same issue right now. I can't use any application that uses NVENC to record videos (e.g. OBS, Nvidia Geforce Experience). According to this nvidia forum thread this is a Lenovo related issue https://www.nvidia.com/en-us/geforce/forums/discover/442631/shadowplay-crashes-consistently-will-not-begin-rec/

Changing the codec to x264 fixed the issue for me. Still, there is a problem with the gpu hardware encoder.

I found a workaround. Some applications that use NVENC work if HDR is turned on (Geforce experience capture works, steam remote play with NVENC works, OBS with NVENC is still broken)

 

1. Go to windows settings.

2. System -> Display -> use HDR 

3. Alt+Z to use Geforce Experience overlay -> Record 

 

Obviously this workaround only works on Legion 5 Pro and won't work on Legion 5 without HDR.

 

I hope this helps Lenovo to sort out and fix this issue as soon as possible.

I'm also experiencing this problem with OBS and also applies to FFMPEG while using the NVEC-Encoding of the integrated NVIDIA GPU.

I've also tried several methods to fix it without any luck.  

 

The x264-Setting just switches the video encoding from the GPU to the CPU and is definitely not suitable for streaming while gaming. (In some cases you will experience frame drops by more than 50% in the video-stream.)

 

Do you have any news on this "Bug"?

 

I would also like to point out that within the OBS-Forums you can find a thread recomending a BIOS downgrade since it looks like the Error started occuing after the latest Bios-Upgrade. (I would not recomend this because I've managed to totaly brick a brand new Notebook with a hard-bios flash years ago - not lenovo btw :-) ... and it also bricked my waranty... )
