Sunshine + Software encoder: not working, bug or missing feature.

[Karabacak021]

Today I started to test Sunshine with this application, it works fine with the Nvidia encoder, but when I move it to Software encoder, it cannot connect.
I am not sure if this is an issue or just missing functionality, so I am posting it here.

In Sunshine I tried different SW Presets, SW Tune, different HEVC and AV1 support settings, but unfortunately with this program it didn't work at all.
At the app, I tried with turned off HDR and turned on HDR, no difference.

Moonlight with Android, connects straight to Software Encoder, so Sunshine works fine.

I'm still on 1.1.0, but according to changelog, there should be no difference.
