@hexa:lossy.network@hexa:lossy.networkyou need to mount certain things into the container02:20:29
@hexa:lossy.network@hexa:lossy.networkyou probably want to run in the host network namespace02:20:37
@macaroniskengz:matrix.orgmacaroniskengz
In reply to @hexa:lossy.network
you probably want to run in the host network namespace
Actually I dont want that
02:21:48
@hexa:lossy.network@hexa:lossy.networkok, so no multicast things for you02:22:49
@hexa:lossy.network@hexa:lossy.networkno avahi discovery02:22:57
@macaroniskengz:matrix.orgmacaroniskengz Yes, due to security concerns I already disabled it in my current setup02:23:53
@macaroniskengz:matrix.orgmacaroniskengzMaybe I am too paranoid, but i dont trust thesd proprietary devices I cant get rid of02:24:25
@hexa:lossy.network@hexa:lossy.networkyou'd probably have to review the systemd hardening yourself02:25:37
@hexa:lossy.network@hexa:lossy.networkI can't explain all options to you02:25:42

@netpleb:matrix.orgnetpleb

right now my frigate config is very basic and I have something like:

# amcrest cameras
cameras.driveway = {
   ffmpeg.inputs = [ {
      path = "rtsp://<user>:<password>:554/cam/realmonitor?channel=1&subtype=1"
      roles = [ "detect" ]
   } ];
};

but I seem to be unable to get any audio from the cameras (I have enabled AAC audio in the camera's UI itself). Is there some additional thing I need to add to frigate/ffmpeg so that it will stream/record audio too?

19:24:56
@netpleb:matrix.orgnetplebI do not have amcrest integration in hass turned on, nor am I using go2rtc in frigate (i am new to all these things), so I am having a hard time grasping what is the minimum I need to setup to get audio working. Any help much appreciated!19:27:26
@netpleb:matrix.orgnetplebbecause I am doing this all on nixos using hexa's excellent modules for hass and frigate, I am also confused about things like: http://card.camera/#/README -- are we still able to use that frigate card, or no?19:33:19
@netpleb:matrix.orgnetpleb for anyone coming along later, I figured out how to get audio working. It seems to have required: ffmpeg.output_args.record = "preset-record-generic-audio-copy"; instead of ffmpeg.output_args.record = "preset-record-generic-audio-aac"; not sure why but whatever ;) 20:16:52

Does anyone use esp32 boards? How far did you managed to get with declarative (or at least programatic) way to reflash the devices?

I have enabled services.esphome, which seems to use /var/lib/private/esphome as workdirectory directory. However, if files in the work directory symlink to elsewher (e.g. /run/secrets/esp/esp32-test.yaml) it complains with the following message.

ERROR Exception in callback functools.partial(<function WebSocketProtocol._run_callback.<locals>.<lambda> at 0xffffa09fc0e0>, <Task finished name='Task-3531' coro=<EsphomeCommandWebSocket.on_message() done, defined at /nix/store/qz8753g0sgf8xy253kpbpbrr3r4j340r-esphome-2024.4.2/lib/python3.11/site-packages/esphome/dashboard/web_server.py:175> exception=ValueError("'/run/secrets.d/11/esp/esp32-test.yaml' is not in the subpath of '/var/lib/private/esphome' OR one path is relative and the other is absolute.")>)

01:49:36
@hexa:lossy.network@hexa:lossy.networkI maintain the esphome package but I have never used the module01:50:37
@hexa:lossy.network@hexa:lossy.networkI run various esp32 though01:50:45
@hexa:lossy.network@hexa:lossy.networkhonestly, that sounds like a base path restriction due to symlinks01:51:51
@hexa:lossy.network@hexa:lossy.network* honestly, that sounds like a base path restriction hit due to symlinks01:52:00
@laurynasp:matrix.orglaurynaspwhat is your setup for managing / flashing the devices? do you flash from nix develop? 01:52:26
@hexa:lossy.network@hexa:lossy.networkthat error is printed by pathlib01:52:55
@hexa:lossy.network@hexa:lossy.networkI have a devshell, yeah01:53:07
