Record audio from another camera

[diogopmartins]

Hello!
I have two cameras in one location, but only one camera has audio. That audio from the audio camera works flawlessly in Frigate.
Is it possible to add the same audio stream to the camera recording that doesn't have have audio?
Many thanks!

This is possible with go2rtc and then just use the restream as the source for frigate camera

How do I do that?

This is my current Config for those cameras:

   Garden1:
  - rtsp://192.168.10.242:554/user=admin_password=_channel=1_stream=0.sdp
  - ffmpeg:back#video=h264#audio=aac
  Garden1_sub:
  - rtsp://192.168.10.242:554/user=admin_password=_channel=1_stream=1.sdp
  Garden2:
  - rtsp://192.168.10.243:554/user=admin_password=_channel=1_stream=0.sdp
  Garden2_sub:
  - rtsp://192.168.10.243:554/user=admin_password=_channel=1_stream=1.sdp`

Thank you!

Well for one ffmpeg:back#video=h264#audio=aac is incorrect and back is supposed to be replaced with the actual name of the camera. Secondly you would just make a similar line to that on the camera without audio pointing at the camera with audio

It's now working! Thank you!

Leave my working config here if useful for someone else.
