Describe the Bug

For NVIDIA geforce series graphics cards below the 4000 series using propriety NVIDIA drivers on linux, AV1 is not supported on encode. sunshine's default setting "Sunshine will advertise support for AV1 based on encoder capabilities" Will result in it attempting to use AV1.

Expected Behavior

Expected Behavior is that of on Windows, in which the auto detect will correctly notice the graphic's card doesn't support AV1. This could be a issue with the NVIDIA driver but ideally things should just worktm.

Additional Context

I run a archlinux setup, however I use the flatpak version of the app. The same problem exists on the AUR as well however. And presumably all arch based setups. I'm not sure if this affects Debian based systems.

How is it detected as supported? In your logs it's clear that it's not supported.

Error: Could not open codec [av1_nvenc]: Function not implemented

Alright I'll try to clarify. "based on encoder abilities" implies that it checks if the encoder (and overall driver, which should check the gpu) supports AV1.

What's happening is that despite it not being supported, it attempts to use AV1 anyways.

You have to manually go into the advanced tab and explicitly set it to "sunshine will not advertise support for AV1"

Which in windows, this doesn't happen. As it autodetects that no, it doesn't support AV1, without needing to go into the advance tab and explicitly change the setting.

I believe this is expected behavior. The encoders are probed to verify them.
