@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.")>)

@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
@hexa:lossy.network@hexa:lossy.networkand when I feel like it (mostly on updates) I run the dashboard and let it update everything01:53:23
@laurynasp:matrix.orglaurynaspDo you mean, this stems from the ESPhome python code opinion symlinks vs regular files01:53:31
@hexa:lossy.network@hexa:lossy.networkplease don't use threads for everything I say01:54:57
@hexa:lossy.network@hexa:lossy.networknobody else is here, so we can just talk here01:55:10
@hexa:lossy.network@hexa:lossy.networkthe context is super clear 😄 01:55:20
@hexa:lossy.network@hexa:lossy.network esphome somewhere uses path.relative_to("/var/lib/private/esphome") 01:55:39
@laurynasp:matrix.orglaurynaspYeah, I was thinking that if I was to go forward with ESPHome dashboard (services.esphome), then I guess my best option would be PR to add an option for systemd services pre-Exec, where I could cp a file across. Would feel hacky. However, my ultimate goal is to automate managament of esp32 devices, so if there is better way, then i would go with that01:55:42
@hexa:lossy.network@hexa:lossy.networkand path is not inside that directory01:55:46
@hexa:lossy.network@hexa:lossy.networkhttps://github.com/search?q=repo%3Aesphome%2Fesphome%20relative_to&type=code01:58:06
@hexa:lossy.network@hexa:lossy.network probably in dashboard_settings.py 01:58:15
@hexa:lossy.network@hexa:lossy.network

Raises ValueError if not relative to ESPHome config folder

01:58:23
@hexa:lossy.network@hexa:lossy.networkthe esphome service to me feels like a stateful way of dealing with configs01:59:04
@hexa:lossy.network@hexa:lossy.networkyou can certainly instruct your secrets management to install the files into /var/lib/private/esphome though01:59:26
@hexa:lossy.network@hexa:lossy.networkjust a symlink won't do01:59:31
@laurynasp:matrix.orglaurynasp just doing a test run to check that ESPhome is happy with secrets.yaml being outside the config dir 02:16:33
@hexa:lossy.network@hexa:lossy.networkgood luck 😄 02:18:18
