Record video

[remko2000]

I istalled this plugin and I get my dafang in homebridge. But I experienced some problems. I don't get audio (if I turn cameraaudio on in homebridge I get ffmpeg exitcode 1). I also want tohave a option to record video. This is the relevant piece of my json:

{
"platform": "Dafang",
"mqtt": {
"hostBroker": false,
"port": 1883,
"host": false,
"debug": true
},
"cameras": [
{
"cameraName": "Garagecam",
"cameraRTSPStreamUrl": "rtsp://xx.x.x.xx:8554/unicast",
"mqttTopic": "schoenmakersloot/dafang/#",
"folder": "/home/pi/dafang/recordings/",
"accessories": [
{
"name": "Record Video",
"type": "recordVideo"
}

The camera appears in homekit but no recordbutton. I also get an error in homebridge:

I do get a recordswitch in Homebridge Config UI X and it records when I activate it but no switch in homekit (no audio). How can I solve this error and how do I add audio to my camera? My camera is a Xiaomi Xiaofang 1S. I already delete persist and accessoiresfolder in homebridge.
