I can't link display+speaker, please help

[Barabba11]

Hi, I?ve followed the instructions:
Create empty stream in the go2rtc.yaml
Go to go2rtc WebUI
Open links page for you stream
Select camera+microphone or display+speaker option
Open webrtc local page (your go2rtc should work over HTTPS!) or share link via WebTorrent technology (work over HTTPS by default)

I didn't know how to create an empty stream and couldn't find this anywhere, so I created a temporary stream by the api with address 127.0.0.1 (epty address won't be saved on config) and restarted, then on config I've deleted 127.0.0.1 so it became empty.
Then I clicked on links and there I clicked on display+speaker = broadcast software, but there isn't a button to save this on config, the next time it became again empty. So I clicked on webrtc.html local WebRTC viewer bu I see black screen, it doesn't work.

Can somebody please simply post here an example config yaml file for broadcasting RTC the desktop? It can be also with ffmpeg, I can't figure out myself. Thank you!

I've tried with ffmpeg trying to collect together random examples, bu i don't know the proper syntax

streams:
  test: ffmpeg:-f gdigrab -framerate 30 -i desktop
ffmpeg:
  bin: c:\ffmpeg.exe

the following command works and output the video with screen grabbed:
ffmpeg -f gdigrab -framerate 30 -i desktop c:log\output.mkv

I have this error:

Empty stream - just name without source.

Empty stream - just name without source.

Thank you for your answer, can you please post me a correct script to use ffmpeg, in particular to open the desktop. I can't find an example that shows me how can I paasa arguments to ffmpeg. Thank you!!

I don't know how to share desktop via FFmpeg from Windows

[Barabba11]

With this command I'm able to record the desktop into a file, how can I use these parameters with go2rtc?
Thank you!
ffmpeg -f gdigrab -framerate 30 -i desktop c:log\output.mkv
