ERROR: FFmpeg exited with code -2
Hello,
I'm trying to setup ip camera on homebridge. I can add the camera to the home bridge but I get the following error:
[Camera-ffmpeg] Snapshot from Camera One at 480x270
[Camera-ffmpeg] An error occurs while making snapshot request
[Camera-ffmpeg] Start streaming video from Camera One with 1280x720@299kBit
[Camera-ffmpeg] An error occurs while making stream request
[Camera-ffmpeg] ERROR: FFmpeg exited with code -2

I've installed homebridge-camera-ffmpeg plugin and config.json looks like this:

{
"platform": "Camera-ffmpeg",
"cameras": [
{
"name": "Camera One",
"model": "MotionEye",
"videoConfig": {
"source": "-re -f mjpeg -i http://user:password@192.168.x.y:8081",
"maxStreams": 2,
"maxWidth": 1280,
"maxHeight": 720,
"maxFPS": 20
}
}
]
}

I'm running a raspberry pi 3 on MotionEyeOS (camera). I've installed FFmpeg on the raspberry.

When I use the source link in my browser, the camera feed appears. Did you configure anything special on your camera?
