Check whether it's viable to expose Vacuum's map as a HomeKit camera

[onfoot]

One would need to be able to create a single-digit-fps MJPEG stream from images generated either by I can't believe it's valetudo or the plugin itself, then dump it using ffmpeg to HomeKit.

I finally got around to toy with this and succeeded. The setup is:

1. An mqtt broker running on my home server. hmq in my case.
2. Vacuum set up to connect to said mqtt broker.
3. I can't believe it's valetudo running on my camera server, with webserver enabled, running on port 3030.
4. homebridge-camera-ffmpeg installed on my camera server's homebridge, properly configured.
5. Camera added to Home.

homebridge-camera-ffmpeg config:

{
      "name": "Vacuum",
      "videoConfig": {
        "source": "-loop 1 -i http://localhost:3030/api/map/image",
        "videoFilter": "pad='ih*16/9:ih:(ow-iw)/2:(oh-ih)/2',scale=1920:1080",
        "maxFPS": 5
      }
}

• -loop 1 sets up ffmpeg so it's constantly loading the generated png for each frame
• pad filter is set up so it expands the generated png to an 16:9 aspect ratio image so it looks right in Home app, then it's scaled using scale down to 1920x1080
• maxFPS set to a reasonable value; at 1 it was having hard time to start live streaming in Home app; at 5 it's instantaneous

Looks cool!
