Speaker and microphone not working

[axelbrunger]

Dear developers:

I installed the latest versions of the doorbird and ffmpeg plugins and latest version of FFmpeg (with libfdk-acc enabled). Nearly everything is working well, except the speaker and audio are not working at all.

The 2019 DoorBird API implies that the RTSP and VIDEO requests are video only. The audio receive and transmit requests are separate commands (with audio-receive.cgi and audio-transmit.cgi). Any ideas how to incorporate these requests into the DoorBird home bridge plugin?

Any ideas and suggestions are welcome.

Best regards, Axel

Audio does not work at all unfortunately

Thanks for replying. I still like the plugin since the video feed is so much faster on my iPhone compared to the DoorBird native App. Thanks for developing it.

Hopefully, there will be a solution for the audio in the future. Please keep us posted.

Or, DoorBird finally comes out with a HomeKit compatible device.

Best regards, Axel

More likely the latter.. it’s waiting on DoorBird however if they provide an audio feed that is supported then I’d definitely add it but it’s not supported at this point

https://www.doorbird.com/downloads/api_lan.pdf?rev=0.27 Time to look at using gstreamer with ffmpeg for audio, might be possible to do this now.

I’ve just subscribed to this thread, fingers crossed! Would be a dream. This plugin has been rock solid

Nudge on this one. @brownad - planning to tackle this one anytime soon? Seems like the last significant piece of functionality for this plugin that’s left to implement, no?

Audio stream doesn’t work tried many times

@brownad - Does the gstreamer example in the latest API doc not work? Curious. I haven't messed with it.

[hjdhjd]

I just did a quick test to see if the audio receive interface actually does anything, and it seems to:

curl -v http://doorbirduser:doorbirdpass@doorbirdip/bha-api/audio-receive.cgi

returns

* Server auth using Basic with user 'doorbirduser'
> GET /bha-api/audio-receive.cgi HTTP/1.1
> Host: doorbirdIP
> Authorization: Basic REDACTED
> User-Agent: curl/7.70.0
> Accept: */*
> 
* Mark bundle as not supporting multiuse
< HTTP/1.1 200 OK
< Content-Type: audio/basic
< Content-Length: 9999999
< Connection: Keep-Alive
< Cache-Control: no-cache
< 

followed by what I assume is audio binary data. It's tantalizing to say the least. I don't want to go down a path that's been trodden...can you share some insight @brownad into the issues you've run into in getting this going?

[brownad]

Haven’t been able to decode the stream correctly yes you are right the audio_receive will return the data but to use gsrreamer with ffmpeg as the docs showed wasn’t something I could get working. Might have looked at this incorrectly though. Help would be most welcome. I know the other committers to the repo would have found a way by now.

I have gotten this working, with some caveats.

It's pretty straightforward to get this going to show you this is possible to do in FFmpeg. Assuming you have FFmpeg and ffplay installed, run this command:

ffmpeg -re -rtsp_transport tcp -i rtsp://doorbirduser:doorbirdpass@yourdoorbirdip:8557/mpeg/media.amp -f mulaw -ar 8000 -i http://doorbirduser:doorbirdpass@yourdirbirdip/bha-api/audio-receive.cgi -f matroska - | ffplay -

You'll see that it does produce the very stream we are seeking to create and plays it in ffplay. You can hear the audio and see the video.

I've mucked around a little with the ffmpeg command line in ffmpeg.js, but it clearly needs work.

Among other issues I noticed...if you enable audio in the camera config, you'll get an error as it tries to create a duplicate microphone device. Easy workaround is don't enable audio in config.json for now...just flip the conditional to always be true around line 310 or so in ffmpeg.js.

@brownad - I think that should give a fair amount to go on. This looks pretty straightforward at this stage, someone needs to spend the time working out what's quirky with the ffmpeg incantation in the code but the above shows it's pretty straightforward to implement using ffmpeg...we're just missing some ffmpeg command line mojo.

[brownad]

That’s pretty sweet. If anyone knows ffmpeg well then could be possible to do

@brownad I created a PR with the updates and instructions to get audio working.

You need ffmpeg compiled with fdk-aac support. You also need to flip audio support on and adjust the source line in videoConfig.

Otherwise, it works. Enjoy.

Microphone support isn't in this BTW...just listen-only audio. Microphone support is a project for another day, assuming some of the issues have been resolved with homebridge.

I noticed other plugins resolved microphone thought the ring one did..

It's possible to do as of the middle of last year. I think we take it a step at a time. Getting one-way audio is a start. Microphone next.

published now.. 👍 @hjdhjd
