Re:Legion 5 Pro NVENC error NV_ENC_ERR_UNSUPPORTED_PARAM

2021-05-12, 22:28 PM

I have the same problem, Legion 5 Pro 16ACH6H here. Nvenc doesn't work in most circumstances (see below for exceptions): Powerdirector, Handbrake (via ffmpeg), Davinci Resolve all fail to use nvenc. I tried downgrading the bios to release 34 (couldn't find older firmware versions), however to no avail. Also, downgrading the nvidia driver to 27.21.14.6156 (the "official" driver from the lenovo support website) didn't work. The only case I got nvenc to work is by using h265 (nvenc) in handbrake, which both shows gpu load while encoding and produces a functional video.

 

Also, I'm fairly certain this is a bios problem, because nvenc with h264 worked at least one time before the bios upgrade to release 36 offered via Lenovo Vantage, and the problem using nvenc is the same in linux (also using handbrake).

 

I sure hope lenovo fixes this soon, as video encoding is one of the reasons I got the (otherwise very nice) laptop.

I'm facing exactly the same issue - reinstalling from scratch, updating drivers and trying the same for older BIOS versions didn't help solving the problem. nvenc simply doesn't work on the/my legion 5 pro which is a huge bummer cause it's been one of the main reason I got this Laptop.

 

I'm fairly certain this is BIOS related and  needs involvement from Lenovo

I can confirm this problem too. I have the Legion 5 Pro for 3 Months now and this problem has been there ever since I had it. It is very much a BIOS problem that needs a fix from Lenovo I have the 34 variant of BIOS and I can atleast swap to Hybrid install the AMD Software for the integrated GPU and then stream with NVENC. It is not a satisfying solution since I 99% use my Laptop on charge so I don't need the Hybrid mode. All we can do is spam Lenovo with this issue because it is on their end to fix it. I have talked to many people since and it really does not seem like an issue we "normal" users can fix.

I have a Lenovo Legion Y540-17 and can confirm I am having the same problem. Spent 2 entire days trying to fix it, reinstalling apps, drivers etc etc, only to find this thread and see that lenovo is to blame. Would very much like to see a fix.

Hello,

 

this is definitely a BIOS/Firmware bug!
I managed to get the older firmware file, rolled back to an older version and *tadaa* it's working again.

 

Also I informed Lenovo Int., Lenovo Europe and Lenovo Germany about this. But nothing happened, shame on you Lenovo!

Here is my suffering and success story with (hopefully) all relevant informations:

Thank you for the information on the problem and on your fix. Unfortunately, for my Legion 5 Pro (16ACH6H) I was unable to find a sufficiently old firmware version.

 


Is there a chance that an admin sees this thread and is able to forward this information to the tech department? Are there any other support channels we could use?

I also have the same issue. It has been two months since the last bios update. I installed all drivers and all updates from the official lenovo website for my laptop but nothing worked. I'm returning my Lenovo Legion 5 Pro now, because this key feature should work on a laptop that costs 1400 and more.
