No audio in recording for Hikvision camera with G.711 ulaw

[PregLizZz]

Describe the problem you are having

Hi,
I have audio in the live view, but in the recording there is no audio.
I use a Hikvision DS-2CD2142FWD-IWS with G.711 ulaw
I tried several different config changes now.
My config below works. Recordings also work, but no sound.
When I change - path: rtsp://127.0.0.1:8554/haustuer to - path: rtsp://127.0.0.1:8554/haustuer?video&audio my recordings are not playable any more, but no errors in the logs.
If I understand correctly normally it should be
output_args:
record: preset-record-generic-audio-aac
together with ?video&audio
for G.711ulaw.
Any help is appreciated.

Did you try transcoding with go2rtc? Eg:

    haustuer:
      - rtsp://user:[email protected]/Streaming/Channels/101
      - "ffmpeg:hauster#audio=aac"

You could also try:

    haustuer:
      - ffmpeg:rtsp://user:[email protected]/Streaming/Channels/101#video=copy#audio=aac
