NVEnc could not be found

[siperwrx]

Hey there,
I just installed v2024.06.16.1 on a new computer w/ Windows 11 (latest version) and I'm getting this popup:
GetTool Version got an empty output for NVEnc
The cause might be that NVEnc could not be found,....

 I can't enable debug because the program closes immediately after this popup. I've installed and reinstalled with the same error. Any ideas?

a. Does Hybrid/64bit/NVEncC.exe exist?
b. You open a terminal inside the Hybrid/64bit-folder and call "NVEncC.exe --check-features" what output do you get?

Ps.: deleted your other thread (one is enough)

a. Yes

Okay, not sure why this happens.
Since you don't have an NVIDIA gpu, you could create a "misc.ini" file next to the Hybrid.exe and put:

[General] nonvidia=true

or

[General] ignore=NVEnc

both should work.
Will do some testing tomorrow to get to the bottom of this, so that the above misc.ini is not needed.

Ps.: I thought I wrote code to ignore NVEnc when no NVIDIA card was detected. (I did, it's still there.)
PPs.: Please also try whether this happens with the latest dev version (you can find it in the 'experimental' folder in my GoogleDrive which is linked on the download page)

[siperwrx]

Thanks for the quick response. Adding the misc.ini file worked!

I'm also using an MSI RTX 4090--would that have anything to do with it?

Then NVEncC should output something like:

and not crash like it does in your case. (assuming the RTX card isn't deactivated or similar and official NVIDIA drivers (Studio recommended) are used)

[siperwrx]

Yeah, I'm using the latest Nvidia Studio driver. Anything else I can test to make sure that the video card is performing correctly? I've been able to use it in Topaz AI and Davinci Resolve.

NVEncC has some other options you can try to figure out where the problem is:

--check-device show DeviceId for GPUs available on system --check-hw [<int>] check NVEnc codecs for specified DeviceId if unset, will check DeviceId #0 --check-features [<int>] check for NVEnc Features for specified DeviceId if unset, will check DeviceId #0 --check-environment check for Environment Info --check-avversion show dll version --check-codecs show codecs available --check-encoders show audio encoders available --check-decoders show audio decoders available --check-profiles <string> show profile names available for specified codec --check-formats show in/out formats available --check-protocols show in/out protocols available --check-avdevices show in/out avdvices available --check-filters show filters available --option-list show option list

seeing this, Hybrid assumes that the NVIDIA card is the one with DeviceId = 0, I suspect this might not be the case on your system.
(iirc. in an older version NVEncC automaticall didn't use devid = 0, but the first NVIDIA card, I might ask the NVEnc dev to add this back(?))
Have to go to bed now, but what does 'NVEncC --check-device' output for you?
