No audio in HA HLS live view with Frigate 0.12 and go2rtc restream

[felipecrs]

And by consequence, no audio when casting the stream to media players either.

That's probably because the RTSP URL has multiple audio codecs but AAC is not the chosen one when pulled by HA.

This fixes the issue for me, but maybe it's not the cleanest solution (maybe this is better).

- f"rtsp://{URL(self._url).host}:8554/{self._cam_name}"
+ f"rtsp://{URL(self._url).host}:8554/{self._cam_name}?video=copy&audio=aac"

f"rtsp://{URL(self._url).host}:8554/{self._cam_name}"

I believe that a consequence of hardcoding the codec in the URL is that the WebRTC card may not work with the camera entity, since audio will always be in AAC format.

Although it does not work today anyway because it uses the Frigate internal host name in the URL:

That's a good point, I don't think the above is a bad solution either, having in the config is probably preferred though

@felipecrs good point but just FYI you shouldn't be using the camera entity with the webrtc card (assuming you are using 3.0). You should just use the url field and provide the name of the camera as it is in the go2rtc config

go2rtc:
  streams:
    your_camera: rtsp://...

type: custom:webrtc-camera
url: your_camera

this will work with go2rtc directly to get the stream instead of just using the rtsp url

Yeah, I know, thanks. That's what I do for my WebRTC cards. I'm just mentioning here a potential consequence of the "fix".

[felipecrs]

I just tried here and it seems that it works even when the camera has no audio.

Ops, actually I forgot to remove the "Closes" from the PR. However this should be fixed anyway as part of #419.
