How to debug 2 way audio?

[tERB00]

Hello! I'm trying to make go2rtc work with my Uniview camera. It is capable of doing 2 way audio via onvif - I know it for a fact because it is working with my Synology Surveillance Station.

My config looks like this:

streams:
RT: rtsp://admin:[email protected]/media/video1

log:
level: debug # default level
api: debug
exec: debug
ngrok: debug
rtsp: debug
streams: debug
webrtc: debug

On the info page it reports:

  "user_agent": "go2rtc/1.9.8",
  "medias": [
    "video, recvonly, H265",
    "audio, recvonly, PCMU/8000",
    "audio, sendonly, PCMA/8000",
    "application, recvonly, VND.ONVIF.METADATA"

On the links page I paste https://files.catbox.moe/5sp12d.mp3 in the input field, press Send and nothing happens. Nothing in the logs.
I also tried curl -d "dst=RT&src=ffmpeg:https://files.catbox.moe/5sp12d.mp3#audio=pcma#input=file" -X POST http://localhost:1984/api/streams and it does not work either.
This is a windows build. I can get jpeg snapshots so I know ffmpeg is working.

I'm not sure if it is a ffmpeg issue or go2rtc issue or what because there is no errors anywhere :) How can I debug this?

According to medias list your camera supports two way audio.
You can check stream info during playing audio (reload it multiple times). Or check network tab in the WebUI. Check if transfer bytes changing during playing.

This thing appears in the network tab when I press Send button:

Huh! This time error logs did show up and it says connection error by ffmpeg. I gave it a different url and it worked this time.
Not sure why there were no logs before since I relaunched the app many times and the config was never changed. Oh well, thanks for the quick reply and for your very useful app!
