frigate [Config Support]: #backchannel=0 argument isn't being passed to go2rtc

Describe the problem you are having

Looks like the #backchannel=0 argument isn't being passed to go2rtc from the Frigate config file. I've even added ' ' around the input as I'm aware that Frigate sees # as comments.

This is causing my doorbell button press to not work.

Yeah we should probably just set that by default since frigate doesn't support 2 way talk (currently).

Jan 11 '23 13:01 NickM-27

by the way do you have force_audio set to False? I wouldn't expect backchannel to work when using ffmpeg

Jan 11 '23 13:01 NickM-27

Yeah I've got it set to False.

restream:
  enabled: True
  force_audio: False

Okay thanks

Which doorbell is yours?

@felipecrs Amcrest AD410

Jan 11 '23 23:01 conorlap

May I ask which integration are you using to detect the button press event?

Jan 11 '23 23:01 felipecrs

Sure, the dahua one:

https://github.com/rroller/dahua

Jan 11 '23 23:01 conorlap

Interesting, when I was using this integration, the button press event was extremely unreliable. Some times it didn't work, some times it took too long to detect.

I know you are not asking this, but I ended up using the Asterisk add-on and configuring the doorbell to connect to it as a SIP server. When someone presses the button, the doorbell calls a number in Asterisk, which I then configured in Asterisk to start my HA automation by using the HA API. It works 100% of the time and it's as fast as it can be.

But maybe the issues I had with the Dahua integration was because I had go2rtc with backchannel activated. Never thought on that!

Jan 11 '23 23:01 felipecrs

The dahua integration always worked well for my ad410 button presses back when I used that

Jan 11 '23 23:01 NickM-27

I got a different doorbell though:

VTO2202F-P-S2

Jan 11 '23 23:01 felipecrs

The dahua integration always worked well for my ad410 button presses back when I used that

Maybe it's because you were not using go2rtc at that time? I was, lol

I was using go2rtc, I even used it with 2 way talk but I had a separate camera setup with backchannel enabled and my main stream was with backchannel disabled

Jan 11 '23 23:01 NickM-27

So apparently I didn't notice, but apparently my AD410 stopped doing anything but recording video/audio since upgrading to go2rtc... adding #backchannel=0 did not help (although it appears its supposed to be default). Moving the stream URL out of the go2rtc section and back to the camera resolves it for me.... I'm on beta8

What do you mean "stopped doing anything but recording video/audio", what do you expect it to be doing? You should probably make your own issue with the config and logs

Feb 22 '23 19:02 NickM-27

Responding to doorbell button presses, config changes, remote restart,, etc. Apparently the AD410, while the backchannel is active on 2 way talk, does not respond to anything at all (a known issue with it, perhaps by design). I can go ahead and make a new issue if you like, I'm probably going to spin up a separate frigate instance to try to pinpoint the issue further, so it'll probably be this weekend

Feb 22 '23 19:02 YBonline

Oh, then that's definitely the backchannel issue. Most likely the config was just not correct to disable it. And backchannel is still on by default with the latest go2rtc release.

Feb 22 '23 19:02 NickM-27

Yes, thats why I decided to comment here instead of make a new issue in the first place, beta 8 includes #5021 which disables backchannel by default?

That PR is not relevant anymore since beta5 which completely reworked go2rtc feature

Feb 22 '23 19:02 NickM-27

Ok, this is my config in the go2rtc section: gp525_doorbell: - rtsp://admin:@10.10.30.30:554/cam/realmonitor?channel=1&subtype=0#backchannel=0

I'm not seeing anything relevant in the logs (which kind of makes sense, there is no error/warnings from Frigate's point of view, its just putting the doorbell into 2 way talk mode and keeping it there), the video stream continues to work

Feb 22 '23 19:02 YBonline

If you open the go2rtc webUI, please get the info for that stream and paste it here.

Okay, it's not seeing your backchannel so you either have another stream which is the one sound this or you have webRTC card / some other instance of go2rtc running somewhere without this option

Feb 27 '23 21:02 NickM-27

So I do use the Frigate card in Home Assistant. When I open the page with the card, there doesn't seem to be any additional consumers or anything in go2rtc. I don't have any separate configuration of go2rtc, and changing the path on the cameras: ffmpeg: input back to the same URL as in the go2rtc section makes the problem go away very consistently, so I'm a bit stumped. I plan to try to get the 2 way audio working as well as soon as I get some free time with go2rtc so I guess I'm going to give that a try next and see if it helps me figure anything else out.

Feb 27 '23 22:02 YBonline

I'd suggest pasting your full config here

Feb 27 '23 22:02 NickM-27

Its long, but here you go: Its the last camera configuration, if I have the configuration as posted, the doorbell doesn't work. If I simply swap the path to the commented out one, I experience no issues at all, even leaving go2rtc configured

Sorry to Pile on with a "me too" moment, but I have an Amcrest AD110 with this same issue. I can get video streams via frigate, and the detection is great, but while Frigate is running, the doorbell is in "talk" mode, which disables the actual doorbell button.

The solution supposedly is to append #backchannel=0 to the stream URL, but Frigate is not passing that information to go2rtc.

go2rtc:
  streams:
    doorbell_live:
      - rtsp://admin:password@ip:554/cam/realmonitor?channel=1&subtype=0
    doorbell_detect:
      - rtsp://admin:password@ip:554/cam/realmonitor?channel=1&subtype=1#backchannel=0
cameras:
  doorbell:
    ffmpeg:
      inputs:
        - path: rtsp://127.0.0.1:8554/doorbell_detect
          input_args: preset-rtsp-restream
          roles:
            - detect
      output_args:
        record: preset-record-generic-audio-copy
    detect:
      width: 640
      height: 480
    live:
      stream_name: doorbell_live

In go2rtc it looks like this:

{
  "producers": [
    {
      "type": "RTSP source",
      "url": "rtsp://ip:554/cam/realmonitor?channel=1\u0026subtype=1/",
      "remote_addr": "ip:554",
      "user_agent": "go2rtc/1.2.0",
      "medias": [
        "video, sendonly, 96 H264/90000",
        "audio, sendonly, 97 MPEG4-GENERIC/16000"
      ],
      "tracks": [
        "96 H264/90000, sinks=1",
        "97 MPEG4-GENERIC/16000, sinks=1"
      ],
      "recv": 8346455
    }
  ],
  "consumers": [
    {
      "type": "RTSP client",
      "url": "rtsp://127.0.0.1:8554/doorbell_detect",
      "remote_addr": "127.0.0.1:43814",
      "user_agent": "FFmpeg Frigate/0.12.1-367d724",
      "medias": [
        "video, recvonly, 96 H264/90000",
        "audio, recvonly, 97 MPEG4-GENERIC/16000"
      ],
      "tracks": [
        "96 H264/90000, sinks=1",
        "97 MPEG4-GENERIC/16000, sinks=1"
      ],
      "send": 8344151
    }
  ]

I've tried doing all sorts of yaml escape characters, but nothing seems to pass the value.

but Frigate is not passing that information to go2rtc.

that is incorrect. Frigate does not pass anything to go2rtc, it literally just hands that part of the config directly to go2rtc. You won't see backchannel in the url part that is shown in the stream info. You can tell it is working because there are no recvonly streams in the producer side.

In this case the problem is likely that you only have #backchannel=0 on the sub stream and not the main stream

Jul 31 '23 20:07 NickM-27

Ok, well thanks for the information. I'm not sure exactly what changed (because I was running the same config for weeks, without a working doorbell button), but I do see that if I put #backchannel=0 on the main stream, it is showing up in go2rtc.

The substream seems to not care either way, which is surprising to me, but maybe that's just expected behavior.

Either way: If I add the backchannel statement to the main stream, I can use the doorbell while watching the video, if I leave it off, it goes into 2 way talk mode.

Thanks for the teachable moment.

@NickM-27 Not to revive this issue thread, but with version 0.14, is there a way to get two-way audio support with the Amcrest doorbell that doesn't break the doorbell button? I assume not since gortc will keep the connection open. I assume it's not possible two wire two different gortc sessions, one for backchannel audio and one for the consumption of Frigate?
