NVENC Codec does not load in obs. (Shared object "libnvidia-encode.so.1" not found, required by "obs")

Hello, please help me with the nvenc plant on the obs!

My characteristics
GPU - Nvidia GTX 1650 Overclocked Low Profile
OS - FreeBSD 14.4
GPU driver - nvidia-driver 595.58.03
Window Manager - bspwm

I tried changing the module's paths through the AI, but it was no use.
The AI also suggested running the recording in advanced mode and checking, but the program returned the error "Operation not permitted."

I spent more than 2-3 hours on this but nothing helped, please help!

I looked at this before, there was another problem with with-glibc-shim, and the error in the condition had been fixed long ago.

Thread 'obs studio nvenc encoding with nv-sglrun need a bit of help'

I'm trying to get obs studio working with nvenc encoding on my dell xps 15 2019 using nv-sglrun,
which should be possible according to this post on bugs.freebsd.org

"At the moment there are no native FreeBSD versions of libcuda.so/libnvidia-encode.so/libnvcuvid.so, so to actually use NVENC we need to load the Linux binaries for those libs with the help of emulators/libc6-shim and the `nv-sglrun` script from that port. Something like this:"

sudo pkg install nvidia-driver linux-nvidia-libs libc6-shim obs-studio

run nv-sglrun and obs

nv-sglrun obs

but I keep getting...

If you're looking for the port that installed that .so file, try something like this: find /usr/ports -iname pkg-plist -exec grep libnvidia-encode.so {} +

This library is NOT provided by upstream for FreeBSD but Linux.

It should be installed as /compat/linux/lib64/libnvidia-encode.so (actually a symlink to libnvidia-encode.so.1 in the same directory and libnvidia-encode.so.1 is actually a symlink to libnvidia-encode.so.595.58.03 currently in the same directory) by x11/linux-nvidia-libs.

Not sure why, but pkg-which doesn't show the origin of the file. But it should be installed.

Code: 
% pkg info -l x11/linux-nvidia-libs-devel | grep libnvidia-encode.so.595.58.03
    /compat/linux/usr/lib/libnvidia-encode.so.595.58.03
    /compat/linux/usr/lib64/libnvidia-encode.so.595.58.03

Note that I'm using -devel variant.
 
I got rid of the array altogether since apparently we only need 2 bits of state per condattr and can just store them directly in condattr. Now nothing should crash. At least not for that reason.
 
Being that BSD does not directly support CUDA I have to hypothesize that even if nvenc runs, it will fall back to CPU encoding. I could be wrong...I was wrong once...Can't say as I liked it, so I vowed to never be wrong again.
 
NVENC doesn't have any kind of CPU fallback. There is the "Video Engine Utilization" metric in the GPU section of nvidia-settings if you want to be 100% sure.
