At the moment I am trying to configure a Raspberry PI Zero W as HomeKit Camera.
The final goal will be to use this as video doorbell with two way audio.

I got stuck configuring the plain homebridge-camera-ffmpeg plugin with one-way audio. As soon as I add the alsa audio input to the config, I get the following error in the log:

[10/3/2019, 8:17:25 PM] [Camera-ffmpeg] ERROR: FFmpeg exited with code 1

I can record audio with the following two commands:

arecord -f S32_LE -r 48000 -D hw:0,0 -d 5 -c 2 capture.wav
arecord -f S32_LE -r 48000 -D plughw:0,0 capture.wav

My config is:

{
        "platform": "Camera-ffmpeg",
        "cameras": [
          {
            "name": "Door Cam",
            "uploader": false,
            "videoConfig": {
                "source": "-re -f video4linux2 -i /dev/video0 -f alsa -i plughw:0,0",
                "stillImageSource": "-re -f video4linux2 -ss 0.9 -i /dev/video0 -vframes 1",
                "maxStreams": 2,
                "maxWidth": 1920,
                "maxHeight": 1080,
                "maxFPS": 30,
                "vcodec": "h264_omx",
                "audio": true,
                "debug": true
            }
          }
        ]
      }

And this is the resulting debug log when I attempt to open the stream in the Home App:

invert the order of the ffmpeg sources with audio first like this

"-re -f alsa -i plughw:0,0 -f video4linux2 -i /dev/video0"

I was playing around with the order earlier... I used your source configuration but this didn't help:

I checked the available streams in my config with

ffmpeg -i <input> 2>&1 | grep "Stream #"

And added

                "mapvideo": "1,0",
                "mapaudio": "0,0"

to my config which solved this issue.

@odx can you please share your camera configuration in your config.json? I would like to see how you put in the mapping. Thank you

I am using both those too. But cannot get around "ERROR: Speaker FFmpeg exited with code 1". Probably not appropriate for this thread. But wondering if you ran in to similar and how you fixed it?
