Not sure i understand the question fully, if i’m using the doorbell? Yes, it’s on my wall fully functional 
It’s this one to be precise: Reolink Video Doorbell PoE | Smart Wired Doorbell with Chime
I have not tried any other devices.
Sorry, I just meant you have the doorbell… which is, according to the developer, the only Reolink product that supports sending audio to it. That means that your workflow likely won’t work for me. I didn’t see any relevant firmware updates for my devices (I don’t have the doorbell one).
Ok, i thought you also have one that you tested with, my bad
But when using https stream then is it possible senda audio to cam?
Depends which camera specifically? Works on the doorbell.
Reolink 823A
This is how i’ve done it on the Reolink Doorbell which supports 2-way audio. Not sure about the 823A but I can see it has a speaker and I believe it is profile T. Results will depend on the camera actually supporting 2-way. I believe the only one that does currently is the door bell but not 100% sure.

Thanks.
How to execute this shell script?
It’s just a post command. You can run it directly from ha with the ha shell command service or on any os directly. Really anywhere. Depends on what you’re trying to accomplish. I feed a tts mp3 into it from Google cloud service so it speaks.
My goal is too send tts to camera. But can you give a hint or tutorial how to get this post command work.
I don’t have any idea where to start.
I looked some youtube videos but wont found anything about how to post shell command in HA.
Is there any tutorial or something?
I’m not sure how you intend on initiating the tts to the bell but you could do this. You’ll need long lived token for the api.
a shell script in /config directory called ttsplay
This shell script will take an input of some text and pass it to the home assistant google_cloud integration to generate a mp3 file speaking that text. It stores in in HA and can be played with ‘URL’.
Then it takes that URL and with some ffmpeg/go2rtc magic it pads the beginning and end a few seconds and plays that mp3 to GO2RTC camera.
#!/bin/bash
TEXT="$1"
LOG=/config/ttslog
echo "TEXT: $TEXT" > $LOG
TOKEN=xxxxxxxxxxxxxxxxxxxxxxxxx
GO2RTC=frontdoor_camera
URL=`curl -v -X POST \
-H "Authorization: Bearer $TOKEN" \
-H "Content-Type: application/json" \
-d "{\"message\": \"$TEXT\", \"platform\": \"google_cloud\"}" \
https://ha.someurl.org/api/tts_get_url | jq -r .url` >> $LOG 2>&1
echo CURLRC=$? >> $LOG
curl -v \
-X POST \
"http://localhost:1984/api/streams?dst=$GO2RTC&src=exec:ffmpeg+-hide_banner+-v+error+-re+-i+$URL+-af+\"adelay=1s,apad=pad_dur=5\"+-c:a+pcm_alaw+-ar:a+8000+-ac:a+1+-vn+-user_agent+ffmpeg/go2rtc+-rtsp_transport+tcp+-f+rtsp+%7Boutput%7D" >> $LOG 2>&1
echo DOORRC=$? >> $LOG
exit 0
You can test it but dropping into the homeassistant container and executing it:
# docker exec -ti homeassistant /config/ttsplay "Hello there. Please leave the package by the door"
If/when it works, you can then execute this via home assistant by adding the shell_command to configuration.yaml and restarting HA. It will take the input of a input_text when it is called. See my automation after.
shell_command:
doorbelltts: >-
/config/ttsplay "{{ states('input_text.tts_door_text') }}"
and create a helper called ‘input_text.tts_door_text’ to hold whatever text you wanted to send.
and then create a simple automation so when you add text to it, it speaks to the doorbell and clears the input for the next time… You could also use a input_select and store canned responses and push those into the text field.

This works too. 
Much easier.

In your last example media_player configuration, what is the frontdoor_send stream?
Nothing fancy.

- ffmpeg:{input}#audio=opus
Ah, I see. Are you using the Frigate integration in Home Assistant or stand alone Frigate? I have the stand alone Frigate and can’t seem to send tts to my doorbell. But reading through the doc’s, it looks like the steam setting needs to be configured in the go2rtc.yaml file which I don’t have. Do you know if I create one manually if this would work or does this only apply to Frigate integrated?
I don’t use frigate as a backend. I only use the frigate card and a regular go2rtc installation. I would guess that if you created a go2rtc config in frigate, it work work similarly.
Okay thanks. I’ll give it a try.
Did you figure this out? I just can’t figure out what to put in the stream object.
I’m running frigate in docker so I can’t think of what makes sense to go here!
Where did you define your frontdoor_send? Is this part also in your yaml.config?
can you elaborate how you did this? all i want to achieve is for my doorbell to play a ding dong sound whenever the doorbell button is press… the ding_dong audio file is locally available in my HA upload folder.
