HomeKit Camera Error(s)

[miniminne]

Hiya! When attempting to add a HomeKit Camera following the example given in the docs, I am hit with this error:

2023/01/31 20:38:40 [ERR] mdns: Failed to unpack packet: dns: empty NSEC(3) block in type bitmap

20:38:51.925 ERR github.com/AlexxIT/go2rtc/cmd/streams/producer.go:52 > error="exec: exit status 1" url=ffmpeg:living_room#audio=aac#audio=opus#async

My config file is set up as such:

streams:
  living_room:
    - hass:ecobee SmartCamera
    - ffmpeg:living_room#audio=aac#audio=opus#async
  doorbell:
    - hass:Circle View Doorbell 2P08
    - ffmpeg:doorbell3#audio=aac#audio=opus#async

Which matches the docs aside from the names. I know these are the correct devices in HASS because if I slightly change the hass: names, it breaks and tells me quite clearly that's the issue.

Did something change recently that doesn't allow go2rtc to grab the correct stream from HASS? Or, is there a different encoder I need to choose?

[AlexxIT]

First, check camera names in go2rtc start logs. Have you seen this names? Second, try to get only video without audio. So remove ffmpeg.

Hey thanks for getting back to me! I did check the logs, and tried to stream just video via Firefox & Edge/Chromium. Both attempts landed me with the above error messages. I did confirm these are the right names via the startup logs and even copy/pasted to verify.

[AlexxIT]

You can try reboot Hass, than reboot go2rtc and try again right after reboot. I can see mdns library fail. I need to find another library.

[miniminne]

So I did try rebooting both HASS & go2rtc but the same errors cropped up ☹️

Digging into this a bit more, it looks like it's expecting some form of DNSSEC record but the response is borked? Which seems odd to me considering its mDNS, not querying an outside server.

I have the same issue

Hi

I would just like to bring attention back to this issue. I certainly appreciate that Homekit is in development phase, so hopefully these common error will help in getting it over the line.

I am too experiencing these same errors with my Belkin Wemo Doorbell

To add, I have an Aqara G2H working perfectly, so I don't think it's my "setup". I have also tried with and without audio on this one, to no avail.

I wonder if the common theme of these devices being doorbells has anything to do with it?

Thanks! :)

Hey @AlexxIT ! Have you had a chance to dive into this issue any more?

[AlexxIT]

I have several projects and they all need attention. Here's an example: https://github.com/AlexxIT/SonoffLAN/issues/1106#issuecomment-1490669165
