I recently purchased an RTX 40-series GPU, and am trying to use the Nvidia AV1 encoder for local recordings. It doesn't work, though, and I'm not sure why. It tells me to make sure my GPU drivers are up to date, and they are. If I use Nvidia HVEC, it works fine. I do have the Vertical OBS plug-in installed, along with the Source Record plug-in, but the error occurs even if neither of those are set to record. I've gathered a log, but nothing jumps out at me in there as being a problem. I'm hoping someone here can read it better than I can, though.
