[Config Support]: Fail to get audio working

[mihoaut]

Describe the problem you are having

Hi all,

i am sorry i tried so much to not bother here with my problem but after days of failing i ask for help. in my HA frigate addon i have neither audio in the live veiw, nor in the recordings, but i would like to have it in both. i have a couple of identical reolink e1 zoom cameras (i managed to have audio with them with the webrtc camera integration, so it must work somehow).

can you tell me what am i doing wrong, to not have audio ? the config is just a current snapshot in time, i had it changed so often already, but i do not manage to have the right combination of necessary config settings i guess.

thank you!

PS: this was the webrtc card url with wich audio is working fine: url: >- ffmpeg:rtsp://admin:XXXXXX@192.168.1.130/h264Preview_01_main#video=copy#audio=opus

Have a look at the documentation: https://docs.frigate.video/configuration/live/#camera-settings-recommendations

You'll want to make sure your camera is sending AAC audio for the best compatibility.

hi hawkeye, thanks for your reply. yes i looked at the docs. i think my config exactly refelcts this part of your mentioned documentation in the section audio support:

go2rtc:
  streams:
    rtsp_cam: # <- for RTSP streams
      - rtsp://192.168.1.5:554/live0 # <- stream which supports video & aac audio
      - "ffmpeg:rtsp_cam#audio=opus" # <- copy of the stream which transcodes audio to the missing codec (usually will be opus)
    http_cam: # <- for http streams
      - http://192.168.50.155/flv?port=1935&app=bcs&stream=channel0_main.bcs&user=user&password=password # <- stream which supports video & aac audio
      - "ffmpeg:http_cam#audio=opus" # <- copy of the stream which transcodes audio to the missing codec (usually will be opus)

also in the section Setting Stream For Live UI of this docu page i have the following present in my config:

   ffmpeg:
      output_args:
        record: preset-record-generic-audio-copy

am i missing something? am i not getting something ? please help me. thx !!!

You need to match your stream names in go2rtc with the names of your cameras, or you need to set the stream_name directive for each of your cameras.

https://docs.frigate.video/configuration/live#setting-stream-for-live-ui

[mihoaut]

i finally have audio. thank you very i was not aware that the names of the cameras have to match as well. i thought only in the path the name must match with the go2rtc names and as video was working in the first place in never was suspicious about this. thank you again very much!

Great! Happy to help.
